UNIT HEATER APPLICATIONS: Installing the Air Discharge Louver Assembly
The body of the air discharge louver assembly is shipped assembled and is packed on top of the furnace cabinet.
The louvers, nuts and bolts, which must be assembled separately, are packed inside the combustion chamber.
It is very important to install the air discharge to direct the flow of the hot air from the furnace as desired for your
application. As you will note from Figure 3G, the air discharge may be installed facing forward (as shown) or
rotated 90 degrees to the left or right. Additionally, the louvers may be installed horizontally or vertically to direct
the flow of the heated air.
1.
Position the body of the air discharge as desired over the hot air outlet on the furnace (i.e. facing
forward, right, or left).
ATTENTION: KEEP THE ORIFICE PLATE IN PLACE (as shown in Figure 3G) when installing
the louver assembly. The orifice plate is necessary for proper air flow from the furnace.
2.
Use the 12 self-tapping screws to securely attach the body of the louver assembly to the furnace cabinet.
3.
Install the louvers in the desired position (i.e. horizontally or vertically) using the bolts and locking nuts
provided.
ATTENTION: DO NOT restrict the flow of hot air from the furnace by closing the louvers, or
damage to the furnace and/or blower motor may occur.

CENTRAL FURNACE APPLICATIONS: Installing Ductwork
If you plan to install ductwork on your furnace, it is mandatory that qualified HVAC personnel design and
install the ductwork system to the CFM and SP specifications provided in this manual. Establish correct duct
size according to the following specifications and use radial bends or turning vanes to allow for proper air flow.
Sizing the Ductwork:
• For Model CB-3500, the outlet on the air discharge is 20" x 20". The main duct (CB-3500)
must initially maintain an outlet size of 20" x 20".
• For Model CB-5000, the outlet on the air discharge is 24" x 24". The main duct (CB-5000)
must initially maintain an outlet size of 24" x 24".
Additionally, to ensure proper air flow from the furnace and to prevent damage to related furnace components,
adhere to the following guidelines for installing ductwork with your CB-3500 or CB-5000 central furnace
application.
Installation Guidelines for Ductwork:
• It is essential that qualified HVAC personnel properly design the ductwork for your
furnace and determine the static pressure for your ducting application;
ATTENTION: Failure to adhere to the static pressure and CFM specifications provided in this
manual may result in damage to the blower motor.
•
The ductwork should be installed directly over the opening in the top of the furnace cabinet (i.e.
where the louver assembly would be installed for free air applications.)
• THE ORIFICE PLATE MUST BE REMOVED for all ductwork applications.
• Existing ductwork at your installation site may NOT be appropriate or meet the specifications for
your furnace installation.
Installing the Energy Retention Disc
Installing the Energy Retention Disc in the Combustion Chamber
ATTENTION: DO NOT fire your furnace without the Energy Retention Disc in place, or combustion
chamber damage will occur. Handle the Energy Retention Disc carefully to avoid damage.
1.
2.
3.
Refer to Figure 3A to review the proper positioning of the Energy Retention Disc.
Swing open the clean-out door on the front of the furnace to gain access to the combustion chamber.

Mounting the Burner on the Hinge Bracket
ATTENTION: Burner tube components (e.g. electrodes and retention head) are factory set. Handle the burner
with extreme care so that burner components are not damaged.
1.
Remove the nut from the mounting flange of the furnace cabinet, and set it aside for later use.
2.
Lift the burner into position so that it is mounted on the hinge bracket on the furnace cabinet.
3.
Carefully swing the burner so the retention head enters the throat of the furnace.
4.
Check the clearance between the retention head and the furnace throat. There must be at least
1/8" clearance, so the retention head is not "bumped" as you swing the burner into firing
position.
NOTE: If the retention head "bumps" the furnace throat, adjust the hinge bracket bolts
as follows:
• While supporting the burner, slightly loosen the two (2) hinge bracket bolts.
• Carefully re-position the burner so it swings freely into its firing position.
• With the burner in its firing position, re-tighten the hinge bracket bolts.

Wiring the Furnace and Pump
WARNING: To avoid electrical shock, make sure that power to the furnace is turned OFF before
connecting any wires. A licensed electrician should install all wiring to your furnace. All wiring must
be in accordance with the National Uniform Electrical Code and local codes. Properly size all wires and use
electrical conduit for all electrical lines.
Wiring your furnace involves the installation of two lines:
(1) A dedicated electrical line to the furnace
(2) A pump electrical circuit from the furnace to the metering pump
Necessary wiring specifications are provided in this section and in the Wiring Schematics located in Appendix B
at the back of the manual.
Wiring to the Furnace
1.
Install a dedicated electrical circuit to the
electrical junction box on the furnace.
Refer to NFPA-70 for wire size and distances
2.
Wire the furnace according to the Wiring Schematic, Figure B1, in Appendix B. Ensure that the
ground wire is attached to the GREEN ground screw on the furnace junction box.
3.
Check for correct voltage at the furnace, and refer to the following chart.
ATTENTION: Incorrect voltage will severely damage the blower motor/furnace components.
DO NOT operate your furnace on any non-specification power system.
ModelVoltage

Operator's Manual: Models CB-3500 & CB-5000
Installing the Suction Oil Line Components
ATTENTION: It is critical that you adhere to the following specifications for suction oil line
installation (oil line from the tank to the pump). If these specifications are not met, the metering pump
will not function correctly and the burner will shut down on reset. The majority of service problems with the
metering pump are caused by leaks at fittings in the suction oil line; these problems are eliminated by ensuring
a 100% airtight suction oil line which slants up to the pump.
• All suction oil line components must be installed as shown in Figures 4H and 4J. Suction line size
is 1/2" diameter. Proper installation allows the suction oil line to be filled with used oil during initial
priming.
• The suction oil line may NOT exceed 6 feet TOTAL vertical lift AND 4 feet TOTAL
horizontal lift (which equals 6.0” hg maximum operating vacuum). To determine if your
suction oil line will meet this specification for maximum operating vacuum, base the calculation for
your installation on the following equivalents:
(1) vertical foot = 0.75” hg (vacuum)
(4) horizontal feet = 0.75” hg (vacuum)
NOTE: ALSO ADD 0.75" hg to the final sum to account for every oil filter, shut-off valve, and
check valve on the suction side of the pump assembly.
Sample calculation: (6) vertical feet x 0.75" = 4.50" hg AND (4) horizontal feet = 0.75" hg
4.50" hg + 0.75" hg + 0.75" hg = 6.00" hg vacuum
•
The metering pump must be installed with a 3/4" check valve and screen at the end of the
suction oil line, or the pump will not maintain its prime.
•Use Permatex #2 non-hardening gasket sealer on every threaded fitting. DO NOT use
teflon tape or teflon pipe dope compounds; the teflon can flake off and cause damage to the
pump head.
•
The suction oil line must be 100% airtight for proper system functioning. Use only
high-quality flare fittings for the copper tubing. DO NOT use compression fittings.
DO NOT use any steel pipe unions. DO NOT use sweat copper pipe. These types of fittings
cause air leaks in the suction oil line and will require re-installation.
•
The suction oil line must slant up to the pump; any high spots will trap air and will not
allow the pump to prime.
1.
Assemble the suction oil line fittings (from the metering pump to the canister filter):
a. Refer to Figure 4H for a detailed look at the metering pump components and fittings.
b. Remove the plug from the 1/4" inlet port of the pump.
c. Install the 1/4" x 3" brass nipple into the 1/4" inlet port on the pump.
d. Install the 1/4" brass street elbow onto the 3" brass nipple; turn the fitting onto the nipple until it is
tight and faces away from the pump mounting plate.
e. Prepare the canister filter for installation:
• Install the 3/4" x 1/4" brass hex bushing into the outlet port of the canister filter.
Check the direction of the arrow for the proper flow.
• Install the 3/4" x 1/2" brass bushing into the inlet port of the canister filter.
• Remove the plug from one of the 1/8" gauge ports in the canister filter and install the vacuum
gauge. Seal the threads of the gauge with Permatex #2 non-hardening gasket sealer.
• Install the 1/2" threaded pipe adapter into one side of the 1/2" ball valve.
• Install the 1/2" MPT x 1/2" flare adapter into the other side of the ball valve.

Install the suction oil line (from the the tank to the canister filter):
a. Refer to Figures 4H and 4J. Prepare a piece of 1/2" O.D. copper tubing (user-supplied) which will
function as the pick-up line from the tank to the canister filter. This copper tubing must have the
following specifications:
• The tube must be one continuous piece of 1/2" O.D. copper tubing with no kinks
or fittings.
• The tube is to slant up from the tank to the pump with no loops or high points to
trap air.
c. Locate the 2" MPT x 1/2" FPT x 1/2" FPT duplex, slip-thru hex bushing (which will eventually be
installed into one of the 2" openings on the tank). Note that the fitting is marked "S" for suction
and "R" for return.
d. Install the 1/2" MPT x 1/2" slip fitting into the "S" side of the 2" duplex slip-thru hex bushing.
e. Install the 1/4" MPT x 1/4" compression fitting into the 1/2" x 1/4" brass bushing.
f. Install the 1/2" x 1/4" brass bushing into the "R" side of the 2" duplex slip-thru hex bushing.
g. Measure the height of the oil tank (from the bottom of the tank, NOT the floor) to the 2"
opening that you are going to use for the supply oil line. Deduct 12" (305mm) from this
measurement and transfer this new measurement onto the 1/2" O.D. copper tubing.
h. Remove the locking nut and ferrel sleeve connector from the 1/2" slip fitting, and slide them
over the copper tubing.
i. Slide the 1/2" O.D. copper tubing through the 1/2" slip fitting, which is installed in the "S"
side of the 2" hex bushing.
j. Install the screen into one side of the 3/4" check valve (making sure the arrow is pointing
away from the screen assembly).
k. Install the 3/4" x 1/2" brass bushing into the 3/4" check valve.
l. Install the 1/2" MPT x 1/2" flare adapter into the 3/4" x 1/2" brass bushing.
m. Slide the 1/2" flare nut over the end of the 1/2" copper tubing, and flare the end of the tubing.
NOTE: Use a high-quality flaring tool (such as a Ridgid Flaring Tool) to ensure that all
flares are made properly (i.e. so they will be 100% airtight).
n. Install the flared oil line and nut onto the assembled check valve/screen and tighten.
o. Pick up the assembled oil line, and carefully guide the end of the tubing with the check valve through
the 2" tank opening.
p. Apply Permatex #2 non-hardening gasket sealer (or equivalent) to the threads of the 2" duplex
slip-thru tank bushing, and tighten this fitting into the tank.
q. Pull the 1/2" copper tubing back up through the slip fitting until you see the mark that you put on the
tubing earlier. Holding the tubing with one hand, push the ferrel sleeve connector and locking nut
down the tubing, then tighten onto the 1/2" slip fitting. The oil line is now installed in the correct
position off of the bottom of the tank.
r. Carefully bend the oil line up to the canister filter; use a spring bender over the oil line while bending
the tubing to prevent kinks in the oil line. Allowing for the flare nut, cut off the excess tubing.
s. Install the 1/2" flare nut onto the tubing, and flare the end of the tubing.
t. Install the end of the tubing with the flare nut onto the 1/2" flare adapter (on the ball valve assembly
at the canister filter).
u. Install a vent from the tank to the outside of the building according to code. The tank must be
properly vented to allow air to enter the tank as oil is pumped out and to safely vent fumes to the
outside. See Figures 4J.
v. Install plugs in all other tank openings as required by code.
w. Inspect the installation. For proper suction oil line operation, make sure all components are
installed and positioned as specified in this manual.

Installing the Pressure Oil Line Components
ATTENTION: It is critical that you adhere to the following specifications for pressure oil line
installation (oil line from the pump to the furnace); if these specifications are not met, the metering pump will
not function correctly and the burner will shut down on reset.
•
The parameters for pressure oil line installation are:
Length of Pressure LineLine Size
Up to 100 feet 3/8" O.D. copper tubing
(Please note that some installations will allow for a greater pressure line length. Contact your
Authorized Clean Burn Distributor for more information.)
•
The pressure oil line must slant up to the burner with no loops or high points to trap air.
•
Local codes may require the installation of an in-line "Fire-O-Matic" safety valve.
Be sure to check all appropriate codes to ensure compliance.
1.
Refer to Figures 4H, 4J, and 4K.
2.
Make sure you have purchased all the necessary fittings to complete the installation correctly.
3.
Install the fittings and components as shown in the related illustrations. Be sure to use Permatex #2
non-hardening gasket sealer to seal every threaded fitting. DO NOT use teflon tape or teflon pipe dope
compounds.
Installing the Compressed Air Line
NOTE: Your air compressor system must supply air pressure to the furnace with the following
requirements: 50 psi and water trap or dryer. If you do not have shop air, an optional air compressor is
available. Contact your local Clean Burn dealer for more information.
1.
Run a compressed air line from your shop air to the connector block on the furnace -- for Model
CB-3500 use minimum 1/4" O.D. copper tubing or equivalent; for Model CB-5000, use 3/8" O.D.
copper tubing or equivalent.
2.
Install an easily accessible shut-off valve in the air line so the burner can be serviced without
shutting off the shop air in your service area.
3.
If necessary, install a pressure regulator (additional to the burner air regulator) in the air line, and
set it at 50 psi.
ATTENTION: DO NOT feed full shop air pressure to the burner or damage to burner
components may occur.
4.
Install a water trap or extractor/dryer in the air line with an automatic drain so compressed air
(rather than water) is supplied to the burner.
ATTENTION: Water must not be fed to the burner, or the flame will be extinguished and the
burner will shut down. Be sure to drain water from your compressor tank on a regular basis to
keep water out of the air line.

Operator's Manual: Models CB-3500 & CB-5000
Installing the Stack
WARNING: Inappropriate stack materials or improper stack design/installation can adversely
affect the proper, safe operation of your furnace. Contact your Clean Burn dealer to purchase the proper
stack components for your furnace.
Stack designs are generally classified as follows:
(1) "Class A" stack through the ceiling of the building (refer to Figure 4L)
(2) "Class A" stack through the sidewall and up the side of the building (refer to Figure 4M)
Stack Design and Specifications
ATTENTION: The stack design must be single and dedicated for each unit (furnace) according to the
following specifications. A single stack serving more than one unit MUST be engineered/certified for that specific
installation (ref. NFPA 211, 3.3.39 and 10.2.1; NFPA 31 6.5.16-18). Failure to adhere to this rule may result in
less than optimal system performance.
Figures 4L and 4M illustrate recommended stack designs. Choose the stack design which is appropriate for your
furnace installation and review all specifications provided in the corresponding drawing. When designing your
stack, adhere to the following specifications:
• Model CB-3500 requires minimum 8" I.D. stack components.
Model CB-5000 requires minimum 10" I.D. stack components.
•
Ensure that the vertical stack height is at least 10 feet PLUS 1.5 feet for every fitting
(e.g. 45 degree, 90 degree, or T) in the stack run. If needed, increase the vertical length
of the stack or install a draft inducer to obtain -.02" W.C. draft over fire. (Section 8 contains details
on adjusting the draft.)
•
Keep the horizontal stack run as short as possible; slant it upward at a minimum of 1/4" per
foot of run.
•
Keep the stack design simple. Complicated stacks (with long runs and many turns) reduce
draft and result in poor burner performance. Your stack may include only one 90 degree turn.
All other stack turns must be at 45 degrees or less to ensure optimal draft and burner
performance.
NOTE: If you plan to use an existing masonry chimney, the chimney must be lined and inside the building.
Exterior masonry chimneys chill the stack gases and result in poor draft and poor burner performance.
ATTENTION: If you have an exhaust fan(s) in your shop, it is critical that you have adequate make up air
(source of fresh air to replace the stale air exhausted by the fan). When an exhaust fan is run without adequate
make up air, the resultant vacuum in the building will draw combustion products back into the burner. This
back draft causes poor burner performance and may damage vital burner components. Refer to Section 8 in this
manual for additional information.
Stack components should be installed in the following order:
(1) Inside stack (stack components from furnace breach to within 18" of ceiling, roof, or sidewall of
building)
(2) Barometric damper
(3) "Class A" stack penetration through the ceiling, roof, or sidewall
(4) "Class A" stack on the exterior of the building
(5) "Class A" stack cap
(6) Draft Inducer (standard component for Model CB-5000; optional accessory for Model CB-3500)
4-18
Operator's Manual: Models CB-3500 & CB-5000
Installing the Interior Stack
WARNING: Single wall stack components may be used only for those portions of the stack
which are located inside your building and away from any fire/burn hazards.
Install the single wall stack with proper clearances from combustibles. Also ensure that the stack
is located a safe distance from all shop personnel.
Install an elbow at the junction of the horizontal and vertical stack components to allow for easy cleaning
of the stack.
ATTENTION: Avoid additional 90-degree turns in the stack. Each additional 90-degree turn
slows down stack gases, creates back-pressure, and results in repeated burner shutdown and
unnecessary service calls. All other turns in the stack should be at a 45-degree (or smaller) angle.
NOTE: IMPORTANT for Canadian Installations - Local codes may require the installation of
a clean-out tee.

Refer to the stack installation drawing, Figure 4L. Install a single wall tee (min. 24 gauge) after the
90- degree elbow in the straight vertical stack section within three to five feet of the furnace breach.
For horizontal stack runs (as shown in Figure 4M), install the tee after the first straight section of pipe.
NOTE: The tee is required to support the barometric damper. You must purchase this tee when
you purchase your stack materials (8" single wall tee - CB#70174 for CB-3500; 10" single wall tee CB#70180 for CB-5000).
For CB-5000 ONLY: Install the 9"-to-10" pipe adapter in the opening of the tee as shown in
Figure 4N.
Install the barometric damper in the opening of the tee (or pipe adapter for CB-5000 furnaces). Use a
small spirit level to make sure that it is properly level.
Install two self-tapping screws (i.e. one on each side of the barometric damper) to hold the damper in
place as shown in Figures 4N and 4O . DO NOT install a screw at the bottom of the barometric
damper, or the flapper of the damper will not operate correctly.
NOTE: Specifications for adjusting the barometric damper for proper draft overfire are provided in

Installing the Stack Safety Switch For Canadian Installations
NOTE: CSA Standards require that all heating equipment must be installed with a stack safety switch. If your
heating equipment is being installed in Canada, follow the instructions listed below.
CAUTION: For your safety and the safe operation of your heating equipment, the stack switch must
be installed by a qualified installer in accordance with the installation instructions provided here. Wiring
must be accomplished in accordance with all applicable codes. Failure to adhere to these safety
recommendations may result in serious personal injury and/or equipment damage.
1.
Follow the instructions in the Operator’s Manual, Section 4 to install a proper stack, including the
barometric damper which must be installed within 40 inches of the breach.
NOTE: The barometric damper must be installed so that it is level and the flapper moves freely.
2.
Ensure that main power to the heating equipment is turned OFF.
3.
Position the stack safety switch over the lip of the barometric damper as shown in Figure 4P.
4.
Drill a 1/8” pilot hole for the mounting screw, and mount the stack safety switch using the mounting
screw supplied with the switch.
NOTE: The mounting screw must not interfere with the free movement of the flapper on the barometric
damper.
5.
Install the wall thermostat according to the instructions provided in the Operator’s Manual, Section 4.
Wire the wall thermostat and stack safety switch in series as shown in Figure 4Q. Install the wire so
that it is secured away from any hot surfaces.
6.
When the heating equipment installation is completed, follow the instructions in the Operator’s
Manual, Sections 5 and 6 to prime the pump and start/adjust the burner.
7.
Follow instructions in the Operator’s Manual, Section 8 to check the draft; this is crucial for the
proper, safe operation of the heating equipment.

Resetting the Stack Safety Switch
WARNING: BURN HAZARD! To prevent serious personal injury, be sure to allow ample
time, at least 30 minutes, for the stack, barometric damper, and switch to cool down before attempting
to access and service these components. It is crucial to identify the cause of the stack obstruction (e.g. heavy
snowfall) and correct it before resetting the stack safety switch and re-starting the burner. DO NOT operate the
heating equipment with an obstructed stack; failure to correct an obstructed stack may result in fire, explosion,
and/or burn hazards causing serious personal injury or death.
NOTE: In locations where heavy snowfall occurs, it is critical that the stack remain unobstructed by snow. For
safe heating equipment operation, be sure to keep the area surrounding the stack clear of snow.
1.
2.
3.
Before resetting the stack safety switch, check the stack to make sure it is clear of any obstructions.
Remove the cover from the stack safety switch, and push the small button in the middle of the switch.
Pushing the stack safety switch reset button will re-establish the thermostat circuit, and the burner will
start (assuming the wall thermostat is calling for heat).
Understanding the Function of the Stack Safety Switch
The Stack Safety Switch monitors the temperature at the barometric damper on the stack and is designed to
detect the obstruction of the free flow of stack gases from the heating equipment and shut down the burner.
Obstruction of the stack results in the “spillage” of stack gases from the barometric damper, which heats up the
switch. The switch then opens, disconnecting the thermostat circuit to the burner, and the burner shuts off.

Installing the Stack Penetration
WARNING: When running the stack through your ceiling, roof, or sidewall, you must use
Class A/UL 103 HT double-wall insulated all-fuel stack components with a stainless steel liner. DO
NOT run single-wall stack through your ceiling, roof or sidewall. NEVER locate a stack joint inside walls or in a
joist spacer. Ensure proper clearances from combustibles per all applicable codes.
1.
2.
Refer to Figure 4L/4M as needed.
Follow the installation instructions provided by the stack manufacturer.
Installing the Exterior Stack
ATTENTION: All exterior stack pieces must be Class A/UL103 HT double-wall insulated all-fuel stack
components with a stainless steel liner.
• DO NOT use Class B or BW Vent/double-wall stack components (for gas fired appliances only).
• DO NOT use Type L Vent/double-wall stack components (for approved fuel oil appliances only).
• DO NOT use black stack pipe (for solid fuel burning appliances only).
• DO NOT use single-wall stack for your exterior stack. Single-wall exterior stack chills the stack
gases and results in poor draft and poor burner performance.
1.
2.
3.
Refer to Figure 4L/4M as needed.
Follow the installation instructions provided by the stack manufacturer.
Install water-tight roof flashing around the penetration of the exterior stack.
NOTE: Clean Burn recommends the use of "Dektite" roof flashing (or equivalent) which ensures a
water-tight seal when installed properly. Contact your local Clean Burn dealer for details.
Installing the Stack Cap
NOTE: Proper installation of a "Class A" stack cap ensures the free flow of stack gases which is
essential for optimal burner performance.
1.
2.
Refer to Figure 4L/4M as needed. Your stack cap should be classified as: "Class A" non-restrictive,
all-fuel type.
Install the stack cap according to the manufacturer's instructions.
Installing the Draft Inducer
ATTENTION: The draft inducer, Field brand model DI-3, is standard equipment for CB-5000 furnaces and
must be installed to ensure proper draft. The Field brand model DI-2 is available as optional equipment for the
CB-3500 furnace. The Field brand draft inducers have been tested for use on Clean Burn furnaces. DO NOT use
other models or brands of draft inducers.
Understanding the Importance of the Draft Inducer
The draft inducer is designed to aid in the removal of the natural draft created by the appliance to vent the
combustion gases to the outside of the building. As the paddle wheel turns, a negative pressure is maintained
within the stack so that the combustion gases can leave the furnace and travel out of the stack. (See Figure 4R.)
Proper sizing, installation, and adjustment of the draft inducer are critical for optimal draft inducer operation.

inducer. Follow directions in Section 8 (Adjusting the Draft Overfire) to set the proper draft.
Wiring the Draft Inducer for Normal Operation*
*(No exhaust fans in the building)
1.
Wire the draft inducer according to the Furnace Wiring Diagram provided in Appendix B at the
back of this manual.
Installing the Wall Thermostat
1.
Select a location for the thermostat on an interior wall away from any hot or cold drafts.
2.
Remove the top cover from the thermostat by pushing gently on the latch at the top center of the
body. (Hold the thermostat base in one hand, and grasp the body with the other hand; push in
on the latch with your thumb, and pull the cover away from the base.)
ATTENTION: DO NOT use a screwdriver to pry the cover off the base, or damage may occur.
3.
Remove the green paper insert and the black plastic battery isolator from the battery section of the
thermostat.
4.
Refer to the Burner Wiring Diagram in Appendix B at the back of this manual. Run two wire,
18-gauge (minimum) thermostat cable from the terminals on the back of the thermostat base to the T/T
terminals of the primary control on the burner.
ATTENTION: NEVER jump between T/T terminals on the primary control without removing
one of the wires. Failure to remove one of the wires will burn out the heat anticipator on the
thermostat and will cause the thermostat to fail.
5.
Mount the thermostat base 60" to 66" from the floor using the hardware provided.
6.
Reassemble the thermostat body onto the base. (Align the hinges at the bottom of the cover with the slots
at the bottom of the base, and swing the cover up into place.)
Replacing the Wall Thermostat Batteries
1.
Proper battery level is indicated by the room temperature being displayed on the LCD screen.
2.
When the battery level becomes low, a battery icon along with the word "REPLACE" will be
displayed in the lower left corner of the LCD screen. Replace the batteries to ensure proper
operation, following the previous instructions on the thermostat disassembly procedure.
3.
If the batteries are not replaced, the display will slowly become dim and not display any
information. The thermostat will eventually not function. If this happens, replace the batteries
immediately.
Inspecting the Furnace Installation
Following completion of all installation activities described in this chapter, the furnace should be
inspected by qualified personnel before firing. This ensures that your installation meets all applicable national and
local codes and allows for any deficiencies to be corrected before furnace startup. Improper installation may void
your warranty.

SECTION 5: METERING PUMP PRIMING
Understanding Metering Pump Priming
Preparing your Clean Burn furnace for operation begins with priming the metering pump. The procedures in this
section must be performed in sequence without interruption to properly prime the pump.
Required Tools and Materials
The following tools and materials are required for oil pump priming and should be gathered before starting any
procedures:
• 3/8" open-end wrench
• 5/8" open-end wrench
•Rags
• Two containers (minimum one-gallon)
• Permatex #2 non-hardening gasket sealer
• Adjustable Wrench
• Pipe Wrench
5-1
Operator's Manual: Models CB-3500 & CB-5000
Priming the Metering Pump
ATTENTION: The priming process must be done precisely as described in this procedure to ensure that all
air is thoroughly bled from the system. Failure to bleed all air from the system will result in repeated burner
shutdowns on reset.

7.
Refer to Figure 5A.
Remove the 1/4" NPT plug from the side of the pump head, and set it aside.
Remove the 1/2" brass cap from the 1/2" brass nipple. Place a funnel in the opening. Slowly
pour used oil into the funnel until oil comes out of the side of the pump head; this will fill the
oil line, canister filter, and pump head with oil.
ATTENTION: NEVER run the pump head dry (i.e. without oil in the pump head); doing so will
severely damage the pump.
Apply Permatex #2 non-hardening gasket sealer to the threads of the plug (removed from the pump head).
Re-install the plug and tighten.
Apply Permatex #2 non-hardening gasket sealer to the threads of the 1/2" brass nipple. Re-install the 1/2"
brass cap on the brass nipple and tighten.
Open the bleeder valve on the pump two to three (2-3) full turns, and position a container to catch oil
which will flow from the bleeder during pump priming.
Close the mini ball valve at the outlet port of the pump head
ATTENTION: Verify that the relief oil line is installed back to the tank before closing the mini ball
valve. Closing the mini ball valve will cause the internal pump relief valve to open.

Activating the Pump
NOTE: The CB-3500 and CB-5000 furnaces feature a priming switch which is mounted on the
left-hand side of the electrical junction box on the front of the furnace cabinet. The priming switch has
two positions:
•
PRIME (switch is in the UP position / orange indicator light is ON): this is used only
for pump priming. When the switch is in the UP position, the pump circuit is activated for
priming. The pump will continue to run as long as the switch is in this position. The oil
primary control circuit is de-activated so the burner cannot run while the switch is in the UP
position.
•
BURNER (switch is in the DOWN position): this is used for normal burner operation.
When the switch is in the DOWN position, the burner controls the operation of the pump.
The pump will only run while the burner is running.
a. Refer to Figure 5B to locate the priming switch.
b. Turn the priming switch to the prime (UP) position. The pump should immediately start running.

9.
Run the pump until a solid stream of oil flows from the pump bleeder. This will bleed all air out
of the suction line, oil filter and pump head.
ATTENTION: For the metering pump to operate correctly, it is very important that the system
is entirely full of oil and all air is bled out. The burner will shut down if there is any air in the
system.
10.
Open the mini ball valve at the outlet port of the pump head to allow the pressure oil line to be filled.
11.
Close and tighten the bleeder on the pump.
12.
Turn the priming switch to the burner (DOWN) position so that the pump stops running.
13.
Disconnect the pressure oil line from the burner and position a container to catch oil which will flow
from the pressure oil line during pump priming.
14.
Turn the priming switch to the prime (UP) position. The pump should start running immediately .
15.
Run the oil pump until the proper flow of oil has been established, and the oil line has been completely
flushed out.
16.
Turn the priming switch to the burner (DOWN) position so that the pump stops running.
17.
Re-connect the oil line to the burner.
Vacuum Testing the Oil Pump
Vacuum testing the oil pump is a very accurate way to determine the following:
• The condition of the pump -- the ability of the pump to pull a vacuum and suck oil from the tank.
• The condition of the fittings, gaskets and seals from the ball valve to the pump -- these
components must all be airtight to avoid suction leaks.
The following procedure provides instructions for vacuum testing the pump and canister filter on
systems equipped with a ball valve.
ATTENTION: For the pump to pull and hold vacuum, it is critical that all fittings are airtight. If any of these
fittings are loose, the pump may not pull a vacuum or may lose the vacuum rapidly. It is also critical that all
fittings in the suction line, including fittings on the canister filter, are 100% airtight.
1.
Follow the instructions to prime the pump (previous procedure).
NOTE: The pump will not pull a vacuum if the pump is dry. There must be oil in the gears of
the pump before the pump can pull a vacuum.
2.
With the pump running, open the bleeder two to three full turns, and make sure that oil is flowing
from the bleeder. DO NOT close the bleeder yet.
3.
Refer to Figure 5A. Close the ball valve at the inlet to the canister filter. Observe the vacuum
gauge.
NOTE: The ball valve must have a stainless steel ball and should be pressure tested by the
manufacturer to ensure that it does not leak. If the ball valve leaks, the vacuum test will not be
accurate.
4.
The vacuum should increase within 30 seconds to 15 inches of vacuum. When the vacuum
gauge reads 5 inches of vacuum, first close and tighten the bleeder, then turn the pump off and
close the mini ball valve at the outlet port of the pump. Observe the vacuum gauge.
NOTE: If the pump will not pull at least 15 inches of vacuum, there is a very serious suction leak, or
the pump is damaged.
5-4
Operator's Manual: Models CB-3500 & CB-5000
Vacuum Testing the Oil Pump (continued)
5.
If there are no suction leaks, the system will hold vacuum.
NOTE: It is acceptable for the vacuum to drop one to five inches within one minute as the seal
in the pump seats. The vacuum should then hold steady for 15 minutes.
ATTENTION: If the vacuum drops more than one to five inches within the first minute, there is one or more
leaks somewhere between the pump and the ball valve. Do the following:
• Wipe your finger along the cylinder at the shaft of the pump. If there is oil here, the pump
seal is damaged. Replace the pump.
• Disassemble and clean all the fittings from the pump to the ball valve. Properly seal all
fittings with Permatex #2 non-hardening gasket sealer or equivalent. Check the condition of
the o-ring on the canister filter and tighten the four canister filter bolts in a crisscross pattern.
• Repeat the procedure to vacuum test the system to ensure that the system is air tight.
6.
Follow the instructions to prime the metering pump after a vacuum test has been performed.

SECTION 6: STARTING AND ADJUSTING THE BURNER
Understanding Burner Startup and Adjustment
Starting and adjusting the burner involves a series of separate procedures which must be accomplished in
sequence without interruption. Review all the procedures before attempting burner startup and
adjustment, paying careful attention to safety information statements.
Preparing the Burner for Startup
1.
Turn the switch on the wall thermostat OFF.
NOTE: If your thermostat does not have an OFF setting, disconnect one thermostat wire so
the burner will not run.
2.
Turn the main power to the furnace ON.
3.
Wait at least 15 minutes until the preheater block is thoroughly warmed up. (Feel the back of the
burner box to make sure the preheater is sufficiently warm. The proving switch on the preheater
block will not allow the burner to start until the block is hot.)
NOTE: The preheater block will remain warm as long as power is supplied to the burner. If the
main power supply is ever turned OFF, you must wait at least 15 minutes until the preheater
block is thoroughly warm before starting the burner.

Fine Tuning the Combustion Air Band for CB-3500 Furnaces:
NOTE: The initial setting of the combustion air band may require additional adjustment.
• Refer to Figure 6A to identify the combustion air band location on the burner.
• Observe the flame. The flame should be yellow-white with sharp tips and no "sparkles."
• If the flame is orange in color or the flame length is too long, the oil you are burning
requires MORE combustion air. OPEN the air band 1/8" to 1/4", and re-check the flame
for the proper characteristics.
• Re-check the flame after five minutes. You should see a yellow-white flame with sharp
tips and no "sparkles", and the flame should extend half of the way down the combustion
chamber.

Fine Tuning the Air Intake for CB-5000 Furnaces:
• Refer to Figure 6B to identify the air intake location on the burner.
• Observe the flame.
• If you see "sparkles" in the flame, or the flame is orange in color, the oil you are burning
requires MORE combustion air. Rotate the locking tab DOWN and OPEN the air intake
1/16" to 1/8", and re-check the flame--you should see a yellow-white flame with no
"sparkles."
• Re-check the flame after five minutes--the flame should still be yellow-white with no
"sparkles."
• Rotate the locking tab UP to lock the air intake in place.
8.
Checking for a Smokeless Burn:
Check for a smokeless burn by observing the stack while the burner is running. If you see any
smoke, repeat the previous steps for setting the combustion air band or air intake and adjusting
the air regulator. After adjusting the combustion air band or air intake, re-check the flame length.
NOTE: Check for a smokeless burn periodically (as you do the flame length). Immediately
readjust the burner if you ever see smoke coming from the stack. Smoke indicates improper air/
fuel adjustment.
NOTE: When using instruments to adjust the burner for a smokeless burn, the following
readings should be achieved:
• Draft over fire should be -.02 inch w.c.
• Adjust for a smoke spot of a trace to #2
• Adjust for a CO2 reading of 8 to 12% or an O2 reading of 4 to 8%
• Cad cell reading of 200 to 500 ohms
Checking the Operation of the Blower Motor
NOTE: It is important to verify that the blower motor operates correctly to ensure that the fan limit control is
properly cycling the blower motor as described below. Also refer to Appendix A at the back of the manual for
additional information on the fan limit control.
1.
2.
3.
4.
Start the burner and adjust it as described previously in this section.
The blower motor will not start until the burner has been running for 5 to 15 minutes to heat
up the combustion chamber and heat exchanger. At this point, the fan limit control will activate
the blower motor.
Once the blower motor has activated, turn the burner off by turning the wall thermostat to OFF.
With the burner off, the blower motor should continue to run for 5 to 10 minutes until the
combustion chamber is cooled down. The fan limit control will then shut off the blower motor.
CAUTION: If the blower motor does not operate as described, immediately shut down your
furnace and contact your Clean Burn dealer.

Understanding the Fan Switches and Hi-Limits on the
CB-3500/CB-5000 Furnaces
The CB-3500 and CB-5000 furnaces feature redundant fan switches and redundant limit switches. The two fan
switches enable efficient working of the fan/blower for both unit heater and central furnace applications. The two
limit switches serve to protect the furnace from damage due to overheating. Review the following specifics on
each of the switches/controls to understand their operation; refer to the Furnace Wiring Diagrams in Appendix
B at the back of this manual to review the installation of these switches.
The Blower/Fan Switch
The CB-3500/CB-5000 furnaces feature an F-180 blower/fan switch (normally open) which is surface-mounted
at the front of the combustion chamber as shown in Figure 7B. The blower/fan switch senses the temperature of
the combustion chamber as the burner is firing. When the combustion chamber reaches the proper temperature,
the switch closes and sends power to the blower motor relay to turn ON the blower. When the wall thermostat
is satisfied and the burner shuts off, the blower/fan continues to run until the switch senses that the combustion
chamber has cooled down. The switch then opens and shuts off the blower/fan.

The Fan Limit Control
Understanding the Operation of the Fan Limit Control
The fan limit control, which is a probe style control, senses air temperature within the furnace cabinet. This
control contains two switches: the fan switch and the limit switch. This control is especially important for the
functioning of the fan with ducted applications.
Fan Switch: The fan switch is normally open and provides power to the fan (or blower). When the fan limit
control senses "Fan On" temperature, the fan switch closes and starts the fan (or blower). When the wall
thermostat is satisfied and the burner shuts off, the fan continues to run until the fan limit control senses the "Fan
Off" temperature. At this temperature, the fan switch opens and shuts off the fan (or blower).
NOTE: The fan limit control has a white fan switch button. Make sure the white button is pulled OUT for
automatic (normal) operation. When the button is pushed in (manual setting), the fan will run continuously.

Limit Switch: The limit switch is normally closed
and provides power to the oil primary control on
the burner. If the fan limit control senses 200
degrees F, the limit switch opens and shuts off
power to the oil primary control and the burner
stops running. The fan (or blower) continues to
run. Once the fan limit control senses 170 degrees
F, the limit switch automatically resets and restarts
the burner.
ATTENTION: It is very important to avoid
cycling the burner on hi limit as described above.
If the hi limit activates, immediately check and
readjust burner settings.
ATTENTION: DO NOT change the fan limit
settings from the specified settings, or severe
damage to the furnace cabinet may occur.

Operator's Manual: Models CB-3500 & CB-5000
The Auxiliary Hi-Temp Limit Switch
The CB-3500 and CB-5000 furnaces are equipped with an auxiliary L-290 high temperature limit switch which
is mounted on a bracket at the front of the combustion chamber as shown in Figure 7B. This switch senses the
build-up of heat within the combustion chamber beyond the fan limit control setting and is designed to protect the
furnace from damage due to overheating.
Understanding the Function of the Auxiliary L-290 Auto-Reset Hi-Temp Limit Switch
If the temperature of the combustion chamber has exceeded the range of the fan limit control, the auxiliary
L-290 auto-reset hi-temp limit switch opens and shuts off power to the primary control on the burner, and the
burner shuts down. After the combustion chamber has sufficiently cooled, the L-290 switch will automatically
reset, and allow the burner to re-start.
The L-290 hi-temp limit switch will open and shut down the burner if any of the following conditions exists:
•
If the fan/blower has stopped running for any reason during furnace operation, the heat
in the furnace may cause the L-290 hi-temp limit switch to open. Ensure that the fan/blower is
functioning properly.
•
The fan limit control is not functioning properly. If the fan limit control has malfunctioned,
the L-290 could cycle on/off repeatedly. If this occurs, contact your Clean Burn Distributor
immediately for service.
•
The furnace is overfiring. Review the directions in Section 6 in the Operator’s Manual to
properly adjust the burner.
•
Improper ductwork is installed on the furnace (applicable only if your furnace is
operating as a central furnace). Ductwork must be installed by qualified HVAC personnel
according to industry standards and the specifications provided in Section 3 of the Operator’s
Manual.
ATTENTION: It is very important to determine the reason for the opening of the L-290 switch and take steps
to correct the cause; failure to do so may result in serious overheating and damage to the heat exchanger of the
furnace. Additionally, if the burner is rapidly cycling on/off, contact your Clean Burn Distributor immediately;
failure to address this situation may result in serious damage to the furnace.

SECTION 8: ADJUSTING THE DRAFT OVERFIRE
Understanding the Importance of Draft
Draft in the furnace is created as the hot combustion gases rise up the stack, creating a negative pressure inside
the stack and the furnace. This negative pressure is measured as inches of water column (W.C.) of draft. A proper
draft overfire of -.02 to -.04 w.c. is essential so that all combustion products travel away from the burner, down the
combustion chamber, through the furnace flues and up the stack.
Checking for Correct Draft Overfire
WARNING: Correct draft overfire is
essential for the proper and safe operation of
your furnace.
Your furnace is equipped with an observation/draft
reading port to check draft overfire. A qualified
serviceman with proper equipment
must check/adjust your furnace for proper draft.
Contact your Clean Burn dealer for this service.
1.
Insert the probe of the draft gauge
instrument into the draft reading port in
the observation port as shown in
Figure 8A.
NOTE: Follow the directions with the
draft gauge to use your specific type of
gauge.
2.
Note the draft overfire reading on the draft
gauge.
ATTENTION: The draft reading should
be in the -.02 to -.04 w.c. range. Poor
draft (i.e. -.01 to +.08) results in back
pressure in the furnace and poor burner
performance. Too much draft overfire
(i.e. greater than -.04) sucks the heat from
the furnace and results in abnormally high stack temperature.

5.
Before starting the burner, turn the weight
on the flapper COUNTERCLOCKWISE
until the flapper remains closed. This will
provide maximum draft for the furnace.
Follow the directions in Section 6 to start and adjust the burner.
With the burner running, check the draft
overfire with a draft gauge.
As shown in Figure 8B, adjust the weight
on the flapper to obtain a consistent
-.02 w.c. draft overfire. Turn the weight
COUNTERCLOCKWISE to increase draft
(i.e. draft increases as the flapper closes).
Turn the weight CLOCKWISE to decrease
draft (i.e. draft decreases as the flapper
opens).
Tighten the locking nut to securely hold
the weight in position.
ADJUST THIS WEIGHT
TO OBTAIN PROPER
DRAFT OVERFIRE

Figure 8B - Adjustment of Barometric Damper
Adjusting Draft Over Fire on Furnaces with Draft Inducers
(CB-5000 Standard; CB-3500 Optional)
NOTE: The draft inducer is purposely sized to create a generous draft. When adjusting the barometric damper,
you will find that the flapper is open most of the time. This allows the draft inducer to suck cool air through the
damper to protect the inducer motor from heat damage.
1.
2.
Use a draft gauge to check draft over fire.
Adjust the barometric damper to obtain -0.02 w.c. draft over fire. If you still have too much draft,
adjust the draft plate on the draft inducer. Move the plate in 1/4" to reduce the draft. Recheck
the draft reading.

Solving Draft Overfire Problems
WARNING! If you cannot achieve proper draft overfire, do not operate your furnace!
Contact your Clean Burn dealer for assistance.
ATTENTION: Backdraft must be resolved or your furnace will not operate correctly!
Under backdraft conditions, draft overfire readings will show positive pressure in the combustion
chamber. Backdraft means that oil spray, combustion products, and heat are blown back against the burner.
Backdraft results in oil-fouled retention heads and electrodes. Severe backdraft will force heat back against the
burner and result in heat damage to the cad cell and transformer.
Backdraft is caused by the following conditions:
• Poor draft caused by improper stack design. (See Section 4.)
• Poor draft caused by improper adjustment of the barometric damper.
• Incorrect combustion air band setting on the burner. (See Section 6.)
• Furnace flues are plugged with ash. (See Section 9.)
• Exhaust fans in your building are sucking gases down the stack.
Understanding the Effect of Exhaust Fans on Draft
Any type of exhaust fan, paint booth, or exhaust system in a building will create negative pressure in the building
unless there is a source of make-up air (i.e. fresh air which enters the building and replaces the air removed by the
exhaust fans.) Refer to Figure 8C on the following page.
If there is insufficient make-up air, the exhaust fan will suck air and combustion gases down the furnace stack
and create backdraft in the furnace. Even if the exhaust fan is on another level of the building or in another room
away from the furnace, the exhaust fan will still create backdraft at the furnace.
Checking Draft Overfire to Determine Severity of Backdraft
The following procedure is an accurate method of determining how much backdraft is created by the exhaust fans.
Once this is determined, you can select the correct method for resolving the backdraft. Refer to Figure 8C on the
following page as needed.
1.
Turn off ALL exhaust fans and close ALL doors and windows in the building (any open door or
window will allow make-up air to enter the building and will negate the test).
2.
Start the furnace and adjust the barometric damper so that the draft overfire is -.02 w.c.
3.
Check the draft overfire again. Now have someone start the exhaust fans.
4.
Note how much the draft overfire has changed.
ATTENTION: If the draft overfire changed towards positive, it is mandatory that make-up air
is provided to the building or severe damage to the furnace and burner will occur (voiding the
warranty). If the draft overfire remained constant at -.02 w.c., there is sufficient make-up air
entering the building, and the exhaust fan is not adversely affecting the draft.

Installing a Make-up Air Louver
Exhaust Fans and Make-up Air Louvers
When exhaust fans are operated in tight buildings, there is little or no source of fresh air to replace the air
removed from the building by the exhaust fan. This results in negative pressure (vacuum) in the building which
creates severe backdraft problems at the furnace.
Properly sized make-up air louvers are designed to allow adequate fresh air to enter the building during operation
of the exhaust fans. The louvers automatically open under the vacuum created by the exhaust fans. The louvers
open just enough to provide the correct CFM of fresh air. The louvers automatically close when the exhaust fans
are turned off.
Sizing the Make-up Air Louver
IMPORTANT NOTE: When using louvers and grills, and the actual free area of the louver or grill is not known,
it is understood that wooden louvers/grills will have a free area of 25%, while metal louvers/grills will have a free
area of 75%. ("Free area" translates into the actual space allowing air to flow through.)
Procedure 1: (a) Determine the CFM rating of the exhaust fan. This information should be stamped on
a label on the exhaust fan. Make sure to add up the total CFM if more than one
exhaust fan exists in the building.
(b) Select the correct size of make-up air louver to provide the required CFM of fresh air.
If you cannot determine the CFM rating of the exhaust fan, use the following procedure.
Procedure 2: (a) Count the total number of exhaust fans in the building.
(b) Close all of the doors and windows in the building except for one overhead garage door.
(c) Start the furnace and allow it to run for 15 minutes to bring it up to temperature.
(d) Set the draft-over-fire for -.02" to -.04" W.C.
(e) Turn ON all of the exhaust fans in the building.
(f) Now close the opened overhead garage door slowly, just until the draft gauge moves down
into a positive (+) draft reading; as soon as it reaches this point, STOP the door at that
position.
(g) Slowly open the door back up, just until the draft reading comes back up to the -.02"
to -.04 W.C.
(h) Measure the size of the door opening, rounding this measurement off to the next largest
even foot.
Example of Calculations for Sizing Make-up Air Louver
Measured door opening: 12 ft. wide x 9 in. high
• Round off to 12 ft. wide x 1 ft. high
• Convert to square feet (in this case it equals 12 ft2)
• Multiply by 1.1 correction factor (12 ft2 x 1.1 = 13.2 ft2)
• Multiply by free area factor (13.2 ft2 x 1.25 = 16.5 ft2)
• Refer to sizing chart (following page) - required grill size would be (1) 54 in2 grill

Installing the Make-up Air Louver
All louvers and grills, regardless of the material from which they are made, must be FIXED in the OPEN position
OR be interlocked with the appliance so that they will open automatically during the operation of the appliance.
The interlock must be placed on the driven member.
NOTE: It is very important to follow these instructions carefully to ensure proper performance of the louver.
1.
2.
3.
The louver must not be close to the furnace. The fresh air should travel at least 40 to 50 feet before
reaching the furnace, so the air warms up. The furnace will not heat well if it is receiving cold return air.
The louver must be high in the sidewall of the building so the cold fresh air does not blow across the
floor level and chill the service personnel.
The louver should be installed in the opposite wall from the location of the exhaust fan. This
will quickly vent diesel exhaust from the top of the building and reduce the amount of run time
for the exhaust fan.

SECTION 9: MAINTENANCE
Understanding Maintenance
Servicing your Clean Burn furnace in a timely manner is very important to keep your furnace running in peak
condition. Just as an automobile requires periodic maintenance such as oil changes, engine
tune-ups, etc. your Clean Burn furnace also requires regularly scheduled service.
WARNING: Failure to maintain and/or improper servicing by unqualified personnel may
adversely affect the proper, safe operation of your furnace, may reduce the service life of your furnace,
and may void your warranty.
The following chart summarizes all the service intervals which are required to maintain your furnace. Service
instructions/procedures for these activities are included in this chapter.
Maintenance Activity

Operator's Manual: Models CB-3500 & CB-5000
Periodic Burner Inspection
Following initial start up of the burner, you should inspect the operation of the burner periodically--ideally on a
monthly basis. Doing so ensures that the system is functioning efficiently and safely.
Follow these guidelines for inspecting the operation of the burner:
• Visually inspect the flame length through the observation
port; the flame should extend no more than one-half of
the way down the combustion chamber.
-If the flame is diminishing or displays wide
variations, clean the canister filter and check
valve/screen (procedures provided in this
section).
-If the flame is firing too strongly (i.e. flame
touches back and/or side walls of the
combustion chamber), check the air pressure
setting (see following guideline).

Cleaning the Tank
DO NOT allow water, sludge, or other debris to accumulate in your oil supply tank to the point that non-combustible or harmful materials are drawn into the pump or burner.
Drain water and sludge from the bottom of your tank at least once a year, and more frequently with water accumulation.
NOTE: If your used oil tank has not been cleaned on a regular basis, a considerable amount of sludge, etc. may
have accumulated on the bottom of the tank. Under these circumstances, it is advisable for you to hire your used
oil hauler to pump the tank. Make sure the tank is pumped to the bottom to remove all sludge, etc. from the tank
(your used oil hauler may charge an additional fee for this type of service). The best time to pump the used oil
tank is at the end of the heating season when the tank is low. This allows sufficient time to refill the tank with
used oil (generated by your company over the summer months) so that you have adequate fuel for the heating
season.
9-6
Operator's Manual: Models CB-3500 & CB-5000
Cleaning Ash from the Furnace
NOTE: The maintenance interval for cleaning ash from the furnace is approximately 700 hours of operation as
indicated on the hour meter on the burner (refer to the servicing intervals at the beginning of this chapter). Be
sure to clean the ash from your furnace at least twice during the heating season. Your furnace may require
more frequent clean out of the ash due to contaminants in the oil or heavy use. As ash accumulates, furnace
heat output declines, and the stack temperature rises. 1/8" of ash has the insulating capacity of one inch of
fiberglass insulation and reduces heat transfer significantly. Never allow more than 1/4" of ash to accumulate in
the combustion chamber, heat exchanger flues, or stack.
CAUTION: Be aware that used oils may contain heavy metallic compounds or foreign
materials. When burned, these compounds are deposited within the furnace, necessitating
careful cleaning. The following protective gear should be worn when cleaning the ash:
• Respirator for fine particles (a dust mask is not acceptable)
• Rubber gloves • Safety goggles
• Protective clothing
CAUTION: Make sure you use a sturdy ladder or scaffolding for safe access to ceiling-hung
furnaces. When cleaning the furnace, static electricity may build up in the shop vac hose. If this occurs,
use #12 copper wire wrapped around the hose with the other end connected to the furnace (or other ground
source) to eliminate the static.

Cleaning the Ash (continued)
1.
Ensure that power has been turned OFF, and all "hot" components have been allowed to cool sufficiently.
Carefully remove the Energy Retention Disc with a long handle or pipe. Lightly vacuum off the Energy
Retention Disc.
2.
Clean the ash from the stack components:
a. Brush accumulated ash from the stack cap.
b. Lightly tap the stack components to loosen the ash.
c. Allow ash and dust to settle in the elbow on the stack.
NOTE: It is not necessary to remove the stack to clean it. You will vacuum ash from the
stack elbow as you clean out the back of the furnace as described below.
d. Remove the clean-out cap from the unused furnace breach.
e. Thoroughly vacuum out the back of the furnace, including the stack elbow, through the
clean-out breach. A long wand on the hose of your shop vac is helpful in reaching all the
way through the back of the furnace to the stack elbow.
3.
Clean the ash from the combustion chamber (see Figure 9E):
a. Bleed down pressure on the air and oil lines by slightly loosening the fittings at the bottom of
the connector block.
NOTE: Turn off the shut-off on the air pressure line.
b. With air and oil pressure completely bled off, disconnect the air and oil pressure lines from
the bottom of the connector block.
NOTE: Cover the lines to keep dirt from entering the air / oil supply
c. Remove the lock-down nuts on the clean-out door.
d. Carefully swing open the clean-out door to expose the heat exchanger flues and the
combustion chamber.
e. Check the color of the ash--it should be light gray or tan.
ATTENTION: White ash indicates excessive air pressure. Black ash or soot indicates lack of combustion air. If these conditions exist, call your Clean Burn dealer. DO NOT overfire
your furnace by turning up the compressed air. Overfiring will damage the combustion
chamber and heat exchanger and will void your warranty.
f. Vacuum the ash from the combustion chamber and the flues.
ATTENTION: When cleaning the combustion chamber, ensure that you do not gouge or
damage the refractory material on the inside of the clean-out door.
NOTE: Avoid "packing" the ash in the tubes by first vacuuming the flues before pushing
the flue brush down the flues. DO NOT bump or bend burner components while cleaning the
combustion chamber.
g. Use a flue brush to thoroughly clean the flues.
h. Thoroughly vacuum any remaining ash residue from the flues. Make sure the back (at the
breach) is still clean.
i. Check the flues for rust.
ATTENTION: The presence of rust in the flues indicates that chlorinated materials are
being burned. Burning chlorinated materials will severely damage your heat exchanger and
void your warranty. Contact your Clean Burn dealer for instructions to test your oil for
chlorine contamination before firing your furnace.
j. Inspect the inside of the clean-out door. Make sure the refractory material on the inside of
the clean-out door is in good condition and the clean-out door seals tightly when closed. If
the door does not seal tightly, replace any damaged components.
9-8
Operator's Manual: Models CB-3500 & CB-5000
Cleaning the Ash (continued)
k. Re-install the furnace components: Swing the clean-out door shut; install and tighten the
lock-down nuts so that the door seals properly. Re-install the air and oil lines on the bottom
of the connector block.
NOTE: You may need to bleed air from the oil line before starting the burner. See Section 5
for the pertinent instructions.
Cleaning and Maintaining the Draft Inducer
The Draft Inducer will require periodic maintenance to ensure that the fan blades do not accumulate excessive ash
which can create vibration, noise, and motor wear.
1.
2.
3.
4.
Ensure that power has been turned OFF, and all "hot" components have been allowed to cool
sufficiently.
Disconnect the wires from the draft inducer and remove it from the stack penetration.
Clean the fan blades with a scraper and wire brush.
Oil the draft inducer motor according to the manufacturer's recommendations.
Annual Burner Tune-up
Your Clean Burn furnace requires annual periodic maintenance. The burner requires an annual tune-up
--similar to an automotive tune-up--to keep it running in peak condition. The burner tune-up should be performed
by a qualified Clean Burn service technician who has the necessary parts and expertise.
Contact your local Clean Burn dealer to schedule the annual periodic maintenance which is usually (preferably)
performed during warm weather to prepare the furnace for the next heating season. Various levels of service are
provided to fit your particular need.
End of Season Maintenance
ATTENTION: Turn main power to your furnace OFF at the end of the heating season. This will prevent
the oil from being "cooked" in the pre-heater block when it is not in use. Failure to do so may result in carbon
build up in the burner preheater block which will block oil flow.
ATTENTION: Turn main power to your furnace OFF at the end of the heating season. EPA
regulations allow your used oil to be burned only for "heat recovery." DO NOT operate your furnace during
warm weather just to burn oil, or severe damage to the combustion chamber/heat exchanger may occur.
Contact your local Clean Burn dealer to schedule your annual burner tune-up. Allow only trained, authorized
service personnel to service your burner.

block will cool down, and the
burner will not re-start the next
morning. To turn the furnace “off ”
overnight, turn the wall thermostat
to OFF. The heater block will stay
hot.
5. If oil residues have built up on
the electrodes and retention head,
follow the instructions in Section 8
to check for proper draft overfire.
Clean the electrodes and retention
head as shown in Appendix A.

Removing the Nozzle for Cleaning:
NOTE: Due to swivel fittings on the air and oil lines, it is not necessary to disconnect these lines when
swinging the burner open.
1.
2.
3.
4.
Remove the lock-down nut on the mounting flange bolt.
Disconnect the burner power cable.
Carefully swing the burner open to its maintenance position.
Remove the nozzle from the nozzle adapter with a 5/8" socket.
Cleaning the Nozzle:
1.
Unscrew the stem from the nozzle head.
2.
Spray WD-40 or equivalent through the orifice to thoroughly remove any blockage.
CAUTION: DO NOT damage or deform the nozzle orifice; DO NOT use a torch tip
cleaner or other inappropriate device to clean the orifice. If the blockage is a "tarry"
material or a hard, black material, call your Clean Burn dealer for service.
3.
Flush all components with WD-40 to remove oil residues.
4.
Reassemble the nozzle components. When tightening the stem, just barely "snug" it down.
DO NOT overtighten.
5.
Check the O-ring on the nozzle stem. Replace the O-ring if it is in the least bit cut or
deformed.
6.
Lubricate the O-ring on the nozzle stem with a couple of drops of new motor oil, then re
install the nozzle.
7.
Check the electrodes for proper gap and clearances.
8.
Re-install the burner and adjust for optimal performance as described in Section 6.
NOTE: If the nozzle plugs within a few days after cleaning, call your Clean Burn Dealer for service.

Installing and wiring
Warning —
1. Always disconnect power source before wiring to avoid electrical shock or damage to the control. All wiring must comply with applicable codes and
ordinances.
2. Thermostat terminals (T–T) provide a current source. Never apply external power to these terminals under any circumstances.
Mounting
• The control may be mounted on a 4” x 4” junction box in any convenient location on the burner, furnace or wall. The location must not exceed the ambient
temperature limit, 140°F.
Wiring
• Wiring must comply with local and national electrical codes, and with the wiring diagram.

1. Safety timing (TFI) test — Remove one cad cell wire (F-F). Start burner.
The control should lockout within the TFI time limit. Replace cad cell wire.
2. Flame failure test
as described on the reverse side of this Data sheet. The control should recycle (restart after 65 seconds).
3. If control does not operate as described, check the wiring.

Power ON
Open all manual oil line valves. Close the line switch.
Self-test 1
The control performs a “boot-up” test to verify internal operation each time power is applied to the black wire. The amber LED turns
on and the test continues for about 5 seconds. If the test fails, the control turns the amber LED off and repeats this test sequence
until successful.
Stand-by
(No call for heat) If Self-test 1 is successful, amber LED turns off and control waits for heat call.
Call for heat Set thermostat and limit to call for heat. Thermostat circuit must be closed and power coming to black wire from limit circuit.
Self-test 2
If a failure occurs in this self-check, the control won’t start and the amber LED blinks 1 second on, 4 seconds off, until serviced or the
problem clears. These failures include CAD cell seeing light, internal fault, or line voltage <90V. See service section.
Burner on
After the self-test, amber LED turns off. The ignitor starts, followed 2 seconds later by the motor.

To Reset
Push in and hold reset button for 2 seconds, then release.
Latch-up
If the control locks out 3 times during a single call for heat, latch-up occurs. The control turns on both the amber and red LED’s constant. You must use the special procedure below to reset the control after latch-up.
repeated burner lockouts must be corrected before returning the burner to normal operation.

Service & Troubleshooting
•
Burner (control) will not come on
No power to control
• Check limit circuit to the control (at least 102 VAC).
• Check all electrical connections.
Internal fault: CAD cell, and line voltage OK, the issue may be
an internal fault . Replace the control.
Check for:
• CAD cell is defective. Replace.
•
Control is in lockout
• Red LED will be on. Press the reset button for 2 seconds.
CAD cell seeing light
• Green LED on, and amber LED blinking 1 second on, 4 seconds
off. Remove one yellow lead from FF terminals. If the amber LED
If the amber LED goes OFF, the control is OK, and;
• light is leaking into the burner housing, OR
• CAD cell is defective, OR
• there is a problem with the CAD cell wiring or holder.
• If appliance was recently shut down, CAD cell may see residual
hot spots in chamber.
To troubleshoot:
• Attach multimeter to monitor CAD cell resistance. Dark
resistance should be over 50K ohms, and room light resis-

Replace cell if necessary, or reinstall and close the burner
housing.
Check for stray light by measuring the CAD cell resistance
looking into the inactive combustion chamber. It should read
at least 50 KOHMS.
Other no start problems
If the CAD cell is OK, and the amber LED still blinks 1 second on, 4
seconds off, the other possible failures include:
