*ATTENTION: A qualified electrician must check the blower motor amperage during operation of the furnace to ensure that
motor amperage does not exceed 85% of the maximum amperage on the motor label. DO NOT operate the blower motor above
85% of maximum amperage or motor damage may occur.
IMPORTANT NOTE: It is essential that qualified HVAC personnel properly design the ductwork
for your furnace and determine the static pressure for your ducting application. Note that existing
ductwork at your installation site may not be appropriate or meet the specifications for this
furnace installation. For static pressure readings as shown in the chart above, the ductwork
should be installed directly over the opening in the SIDE of the furnace cabinet (i.e. where the
louver panels would be installed for free air applications.) For Central Furnace applications,
ductwork may NOT be installed over the bottom opening.
Installing the Hot Air Discharge Components
It is very important to properly install the hot air discharge components (louvers and blank cover panels) to
direct the flow of air from the furnace. As you will note from Figures 3D and 3E, the air discharge panels are to
be installed on the side(s) and/or bottom of the furnace. The air flow may be directed down, front, or back
depending on how the louvers and cover panels are installed.
IMPORTANT NOTE FOR CENTRAL FURNACE APPLICATIONS:
• For ducting applications with static pressure, DO NOT install the louvers. The ductwork should
be installed directly over the desired air discharge opening on the side of the furnace cabinet.

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 national 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
WARNING: A fuse-protected disconnect must be mounted in a readily accessible location for
the installation of the unit. This device can also be used for a disconnect in case of an
emergency.
1.
2.
3.
Install a dedicated electrical circuit to the electrical junction box on the furnace.
WARNING: DO NOT tie into an existing circuit, or electrical overload may occur.
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.
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.

*NOTE: When installing any optional equipment (e.g. air compressor or draft inducer), you do
not need to "upgrade" the fuse protection. The fuse size listed above is sufficient. Make sure a
qualified electrician properly sizes and installs this electrical circuit. 14-gauge copper wire is
required for 15 amp fuse protection.
DO NOT turn on main power until instructed to do so.
Wiring to the Metering Pump
WARNING: DO NOT wire the pump directly into your building's electrical system. The pump
must be activated (receive power) from the burner via the pump electrical circuit. DO NOT wire
the pump directly to a wall outlet so that it runs continuously; this will seriously damage your metering
pump and/or furnace and may result in a fire or explosion hazard.
1.
2.
Install the pump electrical circuit from the furnace to the metering pump location using approved
electrical conduit.
Wire the pump circuit according to the Metering Pump Wiring Schematic in Appendix B at the
back of this manual.

Operator's Manual: Models CB-1500 & CB-2500 (230 V / 50 Hz)
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.
•
•
•
•
•
•
1.
All suction oil line components must be installed as shown in Figures 4H and 4J. Suction line size
is 13 mm (1/2") diameter. Proper installation allows the suction oil line to be filled with used oil
duringinitial priming.
The suction oil line may NOT exceed 183 cm (6') TOTAL vertical lift AND 122 cm (4')
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:
30 cm vertical (1')
= 0.75” hg (vacuum)
122 cm horizontal (4') = 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: 183 cm (6') vertical x (0.75" hg/30 cm) = 4.50" hg AND
122 cm (4') horizontal = 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.
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 this assembly into one side of the 1/2" brass tee.
• Install the assembled 1/2" tee into the 3/4" x 1/2" brass bushing, which is installed in
the inlet port of the canister filter. Make sure that the 1/2" flare adapter is pointing down.
• Install the canister filter assembly onto the 1/4" brass street elbow as shown in Figure 4H.
The canister filter must be installed with the arrow pointing towards the pump
(direction of oil flow).
• Install the 1/2" x 5" brass nipple into the top side of the 1/2" brass tee assembly.

• 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. coppper 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 Figure 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 Relief Oil Line Back to the Tank
ATTENTION: It is critical that you adhere to the following specifications for plumbing the pressure relief
back to the tank.
The metering pump requires the installation of a pressure relief oil line back to the tank that you are pulling oil
from as shown in Figures 4H, 4J, and 4K.
• The pressure relief will open and relieve pressure if there is a restriction in the pressure oil line,
clogged nozzle, etc.
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 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 Line
Line Size
Up to 30 m (100')
10 mm (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.)
1.
2.
3.
4.
•
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.
Refer to Figures 4H, 4J, and 4K.
Make sure you have purchased all the necessary fittings to complete the installation correctly.
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: At least 1.7 bar (25 psi) and a 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.
2.
3.
4.
Run a compressed air line from your shop air to the connector block on the furnace. Use
minimum 6 mm (1/4") O.D. copper tubing or equivalent for the compressed air line.
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.
If necessary, install a pressure regulator (additional to the burner air regulator) in the air line, and
set it at 3.5 bar (50 psi).
ATTENTION: DO NOT feed full shop air pressure to the burner or damage to burner
components may occur.
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.

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. Failure to adhere to this rule may result in less than optimal system performance.
Figures 4L and 4M illustrate these stack designs. Choose the stack design which is appropriate for your
furnace installation and review all specifications provided in the related illustrations. When designing your stack,
adhere to the following specifications:
• Models CB-1500 and CB-2500 require minimum 203 mm (8") I.D. stack components.
• Ensure that the vertical stack height is at least 3 m (10 feet). If needed, increase the
vertical length of the stack or install a draft inducer to obtain -.02" W.C. draft over fire.
• Keep the horizontal stack run as short as possible; slant it upward at a minimum of
6.5 mm (1/4") per 305 mm (12") 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 (from furnace breach to within 45 cm (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

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.
1.
2.
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 or clean-out tee 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: Local codes may require the installation of a clean-out tee.
Installing the Barometric Damper
1.
Refer to Figure 4L. Install a single wall tee (min. 24 gauge) after the 90-degree elbow in the straight
vertical stack section within 90 to 150 cm (3 to 5 feet) of the furnace breach. For horizontal stack runs
(Figure 4M) install the tee after the first straight section of pipe.
NOTE: This 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).
2.
Refer to Figure 4N. Install the barometric damper in the opening of the tee. Use a small spirit level to
make sure that it is properly level.
3.
Install two self-tapping screws as shown in Figure 4N (i.e. one on each side of the barometric
damper) to hold the damper in place. 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
Section 8 of this manual.

Installing the Stack Penetration
WARNING: When running the stack through your ceiling, roof, or sidewall, you must use a
proper insulated "Class A" stack penetration with a stainless steel liner. DO NOT run single-wall
stack through your ceiling, roof or sidewall. Single-wall penetrations do not meet safety codes and may
create a fire hazard. Never locate a stack joint inside walls or in a joist spacer. Ensure proper clearances to
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 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 Optional Draft Inducer
ATTENTION: The draft inducer, Field brand model DI-2, is optional equipment and may be installed
to ensure proper draft. The Field brand draft inducer has 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
4O.) Proper sizing, installation, and adjustment of the draft inducer are critical for optimal draft
inducer operation.

Installing the Draft Inducer
WARNING: Turn OFF the main power to the furnace before proceeding with the installation of
the draft inducer.
ATTENTION: It is very important to install the draft inducer on a vertical section of stack to isolate the
inducer from excessive heat and ash buildup. Never install the draft inducer on a horizontal section of stack
close to the furnace breach where heat and ash will damage the inducer motor.
1.
2.
Refer to Figure 4O. Follow the instructions included with the draft inducer to mount the draft
inducer on the section of single-wall vertical stack.
Position the draft plate all the way out so that it does not reduce the draft produced by the draft
inducer. You will adjust the draft plate later as part of Adjusting the Draft Overfire (Section 8).
Wiring the Draft Inducer for Normal Operation*
*(No exhaust fans in the building. If exhaust fans do exist in the building, refer to pages 8-3 to 8-6.)
1.
Wire the draft inducer according to the Furnace Wiring Diagram provided in Appendix B at the
back of this manual.

6.
Select a location for the thermostat on an interior wall away from any hot or cold drafts.
Remove the top cover from the thermostat by pushing gently on the latch on the right side of the case.
(Hold the thermostat base in one hand, and grasp the cover 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.
Remove the black plastic tab located in the battery compartment.
Refer to the Furnace Wiring Diagram in Appendix B at the back of this manual. Run two wire, 18gauge (minimum) thermostat cable from the terminals on the back of the thermostat base to the terminal
block located on top of the electrical junction box (on top of the furnace cabinet).
ATTENTION: NEVER jump between terminals of the thermostat wire 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.
Mount the thermostat base 152 cm to 168 cm (60" to 66") from the floor using the hardware provided.
Re-assemble the thermostat cover onto the base. (Align the hinges on the side of the cover with the
slots on the base, and swing the cover into place.)
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.

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

5-1
Operator's Manual: Models CB-1500 & CB-2500 (230 V / 50 Hz)
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.
1.
2.
3.
4.
5.
6.
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.

Priming the Metering Pump (continued)
8.
Activating the Pump
NOTE: The furnaces features a priming switch which is mounted on the right-hand side of the electrical
junction box on the front of the furnace cabinet. The priming switch has two positions:
• PRIME: This is used only for pump priming. When the switch is in the PRIME 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 PRIME position.
• BURNER: This is used for normal burner operation. When the switch is in the BURNER
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 position. The pump should immediately start running.

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.
Open the mini ball valve at the outlet port of the pump head to allow the pressure oil line to be filled.
Close and tighten the bleeder on the pump.
Turn the priming switch to the burner position so that the pump stops running.
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.
Turn the priming switch to the prime position. The pump should start running immediately .
Run the oil pump until the proper flow of oil has been established, and the oil line has been completely
flushed out.
Turn the priming switch to the burner position so that the pump stops running.
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.
2.
3.
4.
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.
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.
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.
The vacuum should increase within 30 seconds to 15 inches of vacuum. When the vacuum gauge reads
15 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.

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.

NOTE: The air gauge will not show any pressure until the burner starts. Before starting the
burner for the first time, it is very important to turn the air regulator completely OFF as
described.
6.
Initial Adjustment of the Combustion Air Band:
WARNING: The combustion air band must be properly adjusted to ensure that the burner
ignites and burns correctly. DO NOT attempt to start the burner with the combustion air band
wide open or completely closed. The burner may not ignite correctly. Failure to heed this warning may
result in a fire or explosion hazard.
• Refer to Figure 6A to locate the combustion air band.
• Rotate the combustion air band to adjust it to the appropriate initial slot opening as listed
in the following Initial Adjustment Charts. Use a ruler to accurately set the slot
opening at the widest section of the slot.
IMPORTANT NOTE: This initial setting of the combustion air band will allow you to start the burner.
You will fine tune the combustion air band further as described later in these instructions.
ATTENTION: The settings shown in the charts below are only initial adjustments. Final
adjustments must be done by inspecting the flame length according to the illustrations
provided on the following page.
NOTE: The oil pressure is automatically adjusted by the metering pump. The approximate
oil pressure range during initial startup is 0.07 to 0.28 bar (1 to 4 psi) for Model CB-1500,
and 0.28 to 0.55 bar (4 to 8 psi) for Model CB-2500.

Starting the Burner
1.
Turn the switch on the wall thermostat to HEAT and adjust the thermostat setting above room
temperature to start the burner.
NOTE: If the burner refuses to start, review the Preparing the Burner for Startup procedure. If,
after repeating this procedure, the burner still refuses to start, check the following system components
for proper functioning:
• Verify that the red wire as shown in the Burner Wiring Diagram (Appendix B) is energized
to230VAC.
2.
Adjusting the Air Regulator:
As soon as the burner starts running, turn the knob on the air regulator clockwise to achieve
proper operating air pressure. Refer to the Initial Adjustment Charts.
NOTE: If the safety reset on the primary control is activated and the burner stops running, see
Section 7 for further instructions on restarting your burner.
3.
Observing the Flame Length:
Visually inspect the flame length through the

6.
7.
Check the flame length after the burner has fired for 15 minutes.
Tighten the locking nut on the air regulator.
Fine Tuning the Combustion Air Band:
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 3mm to 6mm (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.
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 and adjusting the air
regulator. After adjusting the combustion air band, 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 10% or an O2 reading of 7 to 9%
• Cad cell reading below 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 switch is
properly cycling the blower motor as described below. Also refer to Appendix A at the back of the manual for
additional pertinent information.
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 switch 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 switch will then shut off the motor.
WARNING: If the blower motor does not operate as described, immediately shut down your
furnace to avoid potential equipment damage and/or fire hazard. Contact your Clean Burn dealer
immediately.
6-4
Operator's Manual: Models CB-1500 & CB-2500 (230 V / 50 Hz)
SECTION 7: RESETTING THE FURNACE AND BURNER
Understanding Furnace/Burner Shutdowns
When troubleshooting furnace/burner shutdown situations, Clean Burn recommends the following
sequence of actions:
• Follow the procedure for Resetting the Oil Primary Control provided in this section.
• Review the material on the following page about the safety switches to determine if the furnace is
shut down on high limit.
• If the burner still will not restart, contact your Clean Burn Distributor for immediate service.
Understanding the Oil Primary Control
The oil primary control will shut the oil pump and oil solenoid off when it detects flame-out during burner
operation. The oil primary control will then wait approximately 15 seconds (while the burner motor, air
solenoid, and transformer are energized) and attempt to re-ignite the burner (recycle mode). If the burner does
not re-ignite, the control will shut the burner off on safety lock-out. The following procedure explains what
should be done when this occurs. It is very important that you follow these instructions precisely when
resetting the safety on the primary control and restarting the burner.
Resetting the Oil Primary Control
DANGER! DO NOT reset the oil primary control if oil mist is present in the combustion
chamber or when the combustion chamber is hot! DO NOT operate your furnace if excess oil,
oil vapor or fumes have accumulated in or near the unit. As with any oil burning appliance, improper operation
may result in a fire or explosion hazard.
1.
2.
3.
4.
5.
Refer to Figure 7A.
Allow 5 to 10 minutes for all fuel mist to exhaust from the combustion chamber.
If the combustion chamber is hot, allow the furnace to cool for at least 30 minutes. DO NOT
push the reset button.
When you are sure that all fuel mist has cleared and the furnace has cooled, push in and hold the
reset button for three seconds, then release. This will reset the control at any time during its operation.
If the burner will not restart, call your Clean Burn dealer immediately.

Operator's Manual: Models CB-1500 & CB-2500 (230 V / 50 Hz)
The Blower/Fan Switch
The CB-1500/CB-2500 furnaces feature an F-180 blower/fan switch (normally open) which is surface
mounted at the front of the combustion chamber (see 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 blower/fan switch closes and sends power to the blower motor to turn ON the blower. When
the wall thermostat is satisfied and the burner shuts off, the blower continues to run until the switch senses that
the combustion chamber has cooled down. The switch then opens and shuts off the blower.
The Hi-Temp Limit Switches
The CB-1500/CB-2500 furnaces also feature two high temperature limit switches which are mounted on a
bracket at the front of the combustion chamber as shown in Figure 7B. The switches sense the build up of heat
within the combustion chamber and are designed to protect the furnace from damage due to overheating. The
limit switches are wired in series and are both auto-resetting.
Understanding the Function of the L-200 Hi-Temp Limit Switch
If the temperature of the combustion chamber is too hot, the L-200 hi-temp limit switch opens and shuts off
power to the primary control on the burner, and the burner shuts off. The blower continues to run to cool down
the furnace. After the combustion chamber has cooled down, the L-200 hi-temp limit switch will automatically
reset and allow the burner to restart.
ATTENTION: If the L-200 hi-temp limit switch is opening repeatedly, the burner MUST be readjusted
according to the instructions in Section 6 to correct the overheating problem, or serious damage to the
furnace may occur.
The L-200 hi-temp limit switch will open and shut down the burner if any of the following conditions exists:
•
•
The furnace is over firing. Review the directions in Section 6 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.
Understanding the Function of the L-290 Auxiliary Auto-Reset Hi-Temp Limit Switch
The L-290 auxiliary auto-reset high temperature limit switch is a back-up safety switch for the L-200 hi-temp
limit switch.
Both the L-200 and L-290 auxiliary hi-temp limit switches will open and shut down the burner if:
•
the blower has stopped running for any reason during furnace operation, the heat
in the furnace will cause the limit switches to open. Ensure that the blower is functioning properly.
ATTENTION: It is very important to determine the reason for the opening of the limit switches 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.
2.
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.
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.

COUNTERCLOCKWISE to increase draft
(i.e. draft increases as the flapper closes).
Turn the weight CLOCKWISE to decrease

Tighten the locking nut to securely hold
the weight in position.
Figure 8B - Adjustment of Barometric Damper
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. (See Above)
• 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.
8-2
Operator's Manual: Models CB-1500 & CB-2500 (230 V / 50 Hz)
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.
2.
3.
4.
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).
Start the furnace and adjust the barometric damper so that the draft overfire is -.02 w.c.
Check the draft overfire again. Now have someone start the exhaust fans.
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. 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 amount 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 volumetric flow rate of the exhaust fan. This information should be stamped
on a label on the exhaust fan. Make sure to add up the total volumetric flow rate if more
than one exhaust fan exists in the building.
(b) Select the correct size of make-up air louver to provide the required fresh air.
If you cannot determine the volumetric flow rate of the exhaust fan, use the following procedure.
Procedure 2: (a)
(b)
(c)
(d)
(e)
(f)
Count the total number of exhaust fans in the building.
Close all of the doors and windows in the building except for one overhead garage door.
Start the furnace and allow it to run for 15 minutes to bring it up to temperature.
Set the draft-over-fire for -.02" to -.04" W.C.
Turn ON all of the exhaust fans in the building.
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.
Example of Calculations for Sizing Make-up Air Louver
Measured door opening: 366 cm (144") wide x 30 cm (12") high
• Convert to cm2 (ft2) - in this case it equals 10,980 cm2 (1728 in2)
• Multiply by 1.1 correction factor: 10,980 cm2 x 1.1 = 12,078 cm2
(1728 in2 x 1.1 = 1901 in2)
• Multiply by free area factor: 12,078 cm2 x 1.25 = 15,098 cm2
(1901 in2 x 1.25 = 2367 in2)
• Refer to sizing chart on the following page - required grill size would be:

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 10-13m
(40-50 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 and may reduce the service life of
your furnace.
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.

At least once a year
*It is very important to clean ash from the furnace on schedule. Normal use of the furnace requires
clean-out at least twice during the heating season. Heavy, around-the-clock usage requires more
frequent clean-out. For instance, one month of continual running of the furnace is 720 hours (24 hours x
30 days = 720 hours).
NOTE: IMPORTANT! Record all maintenance activities in the Maintenance Record provided in the
Appendixes.

section).
KEEP FACE AWAY
OPEN PORT SLOWLY
-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).
• Check the air pressure by observing the air gauge; proper air pressure settings are provided in
Section 6. DO NOT overfire the burner; doing so on a continual basis will damage the furnace.
• Check the combustion air band setting for the proper opening and clean away any dust/debris as
necessary. Note that the air band should NEVER be set fully open or closed.
• Check the draft over fire reading as specified in Section 8.

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. 3mm (1/8")
of ash has the insulating capacity of 25mm (1") of fiberglass insulation and reduces heat transfer
significantly. Never allow more than 6mm (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.

Ensure that power has been turned OFF, and all "hot" components have been allowed to cool
sufficiently. (Allow at least one hour for the Energy Retention Disc to cool.)
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.
Clean the ash from the combustion chamber (see Figure 9D):
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. Carefully remove the Energy Retenton Disc with a long handle or pipe. Lightly vacuum
the Energy Retention Disc.
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.
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. 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.

Cleaning Ash From the Furnace (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 the Check Valve / Screen
This procedure applies to furnace installations with inside and outside tanks. The following protective
gear should be worn when cleaning the check valve/screen:
• Rubber gloves
• Safety goggles

Refer to Figure 9E. Remove the one-piece suction oil line from the tank.
Remove the check valve and screen. Clean these components in a parts washer.
Check the operation of the check valve. The valve must seat so it is airtight to hold pump prime.
Re-assemble and re-install the components. Apply Permatex #2 non-hardening gasket sealer or
equivalent to the threaded fittings. Firmly tighten all connections so the suction line is 100%
airtight.
Follow pump priming instructions in Section 5 to re-establish prime.

Cleaning the Tank
DO NOT allow water, sludge, or other debris to accumulate in your oil supply tank to the point that noncombustible 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.
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. 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.

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.
Remove the lock-down nut on the mounting flange bolt.
2.
Disconnect the burner power cable.
3.
Carefully swing the burner open to its maintenance position.
4.
Remove the nozzle from the nozzle adapter with a 5/8" socket.
Cleaning the Nozzle:
1.
2.
3.
4.
5.
6.
7.
8.
Unscrew the stem from the nozzle head.
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.
Flush all components with WD-40 to remove oil residues.
Reassemble the nozzle components. When tightening the stem, just barely "snug" it down.
DO NOT overtighten.
Check the O-ring on the nozzle stem. Replace the O-ring if it is in the least bit cut or
deformed.
Lubricate the O-ring on the nozzle stem with a couple of drops of new motor oil, then reinstall the nozzle.
Check the electrodes for proper gap and clearances. (Figure A3)
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.
