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.
5.
Install and tighten the lock-down nut on the mounting plate bolt to secure the burner in its firing
position.

Remove and discard the red caps and plugs from the
fittings and ports on the connector block. DO NOT
allow any dirt/debris to enter these components
during furnace assembly.
ATTENTION: The connector block includes an accumulator.
The accumulator functions like a shock absorber on the oil line
to prevent pressure buildup and protect vital burner
components. It is important that the connector block is
installed as shown so that the accumulator is in a vertical
position to prevent sediment from settling in the accumulator.
Never operate your furnace without the connector block and
accumulator properly installed on the furnace, or damage
may occur to vital burner components.
ATTENTION: DO NOT use teflon tape on any fittings.
Teflon tape residues will plug vital burner components.

Remove and discard the red caps from the oil line tubing.
2.
Loosely install the oil line tubing into the oil line fitting on the burner.
3.
Use a wrench to slightly rotate the oil line fitting on the burner counterclockwise so the tubing lines up
with the swivel assembly. Slightly bend the tubing as shown in Figure 3G, if required, to "line up" the oil
line.
4.
If necessary, use a tubing cutter to cut the tubing to the proper length.
ATTENTION: Due to adjustment of the burner hinge bracket, the oil line tubing may need to
be cut to fit properly. DO NOT lift up on the burner when installing the oil line tubing to
compensate for oil line tubing that is too long. This will place the weight of the burner on the
swivel fitting and result in leaks at the swivel fitting seal.

Constructing a Non-Combustible Floor
1.
Determine the size of floor you will need to construct:
• Measure the width and length of the furnace cabinet
• Add 12" (minimum) to all sides of the cabinet to achieve the total measurement for the
non-combustible floor.
The CB-1400 is approximately 34" x 30"
34" + 12" + 12" = 58"
30" + 12" + 12" = 54"
Therefore your non-combustible floor will need to be 58" x 54"
2.
Refer to Figure 4E. Install two (2) pieces of 5/8" sheet rock on top of the combustible material
(wooden floor, wooden beams, etc.) The sheet rock must be cut to the size of the total
non-combustible floor area.
Place a sheet of 24-gauge (minimum) galvanized sheet metal on top of the 5/8" sheet rock;
the sheet metal must cover the sheet rock completely.
Place 4" thick (minimum) hollow masonry block, end to end, on top of the 24-gauge sheet metal
to make a solid foundation. Be sure to add center cross blocking to safely and adequately support

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.
WARNING: DO NOT tie into an existing circuit, or electrical overload may occur.
2.
3.
Wire the furnace according to the Wiring Schematic, Figure B1, in Appendix B.
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.

sure a qualified electrician properly sizes and installs this electrical circuit.
4.
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.
Wire the pump circuit according to the appropriate Wiring Schematics, Figures B1 and B4
(Appendix B).

Operator's Manual: Model CB-1400
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 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

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 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 and Low-Flow Check Valve
ATTENTION: It is critical that you adhere to the following specifications for pressure relief and
low-flow check valve installation; if these specifications are not met, the metering pump will not
function correctly and the burner will shut down on reset.
The metering pump requires the installation of a pressure relief and low-flow check valve as shown in Figures
4H, 4J, and 4K.
• The pressure relief will open and relieve pressure on the line if there is a restriction in the
pressure oil line, clogged nozzle, etc.
• The low-flow check valve is a vital component which maintains pressure in the oil pressure
line.
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.

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. Use minimum
1/4" O.D. copper tubing or equivalent for for the compressed air line.
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: Model CB-1400
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-1400 requires minimum 8" I.D. stack components.
• Ensure that the vertical stack height is at least 10 feet PLUS one foot 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 (the stack components from the furnace breach to within 18" of the ceiling, roof,
or sidewall of your 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 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.
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 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).
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.

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.
2.
3.
4.
5.
6.
7.
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.
Ensure that main power to the heating equipment is turned OFF.
Position the stack safety switch over the lip of the barometric damper as shown in Figure 4O.
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.
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 4P. Install the wire so that
it is secured away from any hot surfaces.
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.
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 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
4Q.) Proper sizing, installation, and adjustment of the draft inducer are critical for optimal draft
inducer operation.

Refer to Figure 5C.
Remove the 5/8" 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 (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 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.

Activating the Pump
WARNING: Activating the pump for pump priming involves running the burner by
jumping the "F" terminals of the oil primary control. This procedure (i.e. jumping the "F"
terminals) should be used only for this specific purpose--never for normal operation. This
procedure is accomplished easily by two people: one at the burner and one at the wall thermostat.
ATTENTION: When performing this procedure, never jump from an "F" terminal to a "T" terminal,
or severe damage to the primary control will occur.
a. Refer to Figure 5D, Step 1.
ATTENTION: Ensure that the plastic barrier strip is in place between the "F" and "T" terminals as
shown in Figure 5D before proceeding; failure to do so will result in damage to the primary control.
b. Connect a jumper wire to one "F" terminal on the primary control.
c. Adjust the thermostat above room temperature. The burner should start running.
d. Immediately turn the knob on the air regulator clockwise until the air gauge registers 10 to
12 psi. You will adjust the air pressure further during burner startup and operation.
NOTE: No air pressure will register on the air gauge until the burner starts running.
e. The pump should start running.
f. Refer to Figure 5D, Step 2.
g. Within ten seconds, jump the "F" terminals by connecting the jumper wire to the other "F"
terminal.
NOTE: If the safety reset on the primary control activates and the burner stops running while
performing this procedure, follow the instructions in Section 7 to reset the oil primary control
and restart the burner.

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.
Close and tighten the bleeder on the pump.
Remove the jumper wire from the primary control; the burner and pump should stop.
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.
Reset the primary control; the burner should start running. Within ten seconds, jump the "F"
terminals by connecting the jumper wire to the other "F" terminal. This will start the pump again
and allow the oil line to flush out.
Run the oil pump until the proper flow of oil has been established, and the oil line has been
completely flushed out.
Remove the jumper wire from the primary control; the burner and pump should stop.
Re-connect the oil line to the connector block.
Make sure that the cad cell wires are connected to the "F" terminals as illustrated in Figure 5D,
Step 3. Save the jumper wire for future pump priming.
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.
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 5C. Close the ball valve and 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.
5-6
Operator's Manual: Model CB-1400
Vacuum Testing the Oil Pump (continued)
4.
5.
The vacuum should increase within 15 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.
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.
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.
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 Chart. Use a ruler to accurately set the slot opening at
the widest section of the slot. 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 chart 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 1 to 4 psi for Model CB-1400.

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.
Observing the Flame Length:
Visually inspect the flame length through the
observation port. Refer to Figure 6B for an illustration
of the desired flame length. The flame should extend
no more than one-half of the way down the combustion
chamber.
WARNING: The observation port gets hot as the
burner fires. To avoid personal injury, always wear
heavy work gloves and safety glasses when opening the port
and viewing the flame.

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 1/8" to 1/4", and recheck the flame for the proper
characteristics.
• Recheck the flame after five minutes. You should see a yellow-white flame with sharp tips and
no "sparkles", and the flame should extend half 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 Fan Motor
NOTE: It is important to verify that the fan motor operates correctly to ensure that the fan limit control is
properly cycling the fan motor as described below. Also refer to Appendix A (A-10) 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 fan 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 fan motor.
Once the fan motor has activated, turn the burner off by turning the wall thermostat to OFF.
With the burner off, the fan 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 motor.
WARNING: If the fan 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.

SECTION 7: RESETTING THE OIL PRIMARY CONTROL
Understanding the Oil Primary Control
NOTE: The CB-1400 primary controller (CB Part #33400) is a recycle type control, which features
interrupted ignition operation.
The oil primary control will go into safety lockout and shut the burner off when it detects flame-out
during burner operation. The oil primary control will then wait approximately one to two minutes 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. 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.
Using the Reset Button
DANGER! DO NOT push the reset button more than once! DO NOT push the reset button 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 your furnace. As with
any oil burning furnace, improper operation may result in a fire or explosion hazard.
1.
Refer to Figure 7A.
2.
Check the combustion chamber for fuel mist by shining a flashlight through the observation port.
If you see fog (fuel mist) in the chamber, DO NOT push the reset button.
3.
If the combustion chamber is hot, allow the furnace to cool for at least 30 minutes. DO NOT
push the reset button.
4.
When you are sure all mist has been cleared from the chamber and the combustion chamber is
cool, depress the red button on the primary control for a minimum of three (3) seconds, then
release. Reset the control ONCE ONLY.
5.
If the burner will not restart, call your Clean Burn dealer immediately.

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.

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.)
• Clean-out gasket on Clean-out door is out of position (See Section 9).
• Exhaust fans in your building are sucking gases down the stack. (See following pages)
8-2
Operator's Manual: Model CB-1400
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.
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 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 (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)
(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, 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

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.

*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
Appendix C.

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 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.
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)
• Safety goggles
• Rubber gloves
• Protective clothing
CAUTION: Make sure you use a sturdy ladder or scaffolding for safe access to ceiling-hung
furnaces.
NOTE: 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 target to cool.
Clean out the burner throat:
a. Disconnect the burner power cable.
b. Remove the lock-down nut and swing the burner open.
c. Clean out the burner throat using a small scraper to remove the residues.
ATTENTION: Keep the burner open (swung out) so that you do not knock or bend burner
components when cleaning out the combustion chamber.
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 clean-out tee or elbow.
d. Vacuum ash from the clean-out tee, or disconnect the stack and vacuum ash from the elbow.

Operator's Manual: Model CB-1400
Cleaning Ash from the Furnace (continued)
4.
Remove the clean-out door to clean ash from inside the combustion chamber (see Figure 9E):
a. Disconnect the stack from the furnace breach.
b. Remove the clean-out panel from the back of the furnace.
c. Remove the clean-out door to expose the heat exchanger flues and the combustion
chamber.
d. 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 pressure. Overfiring will damage the combustion chamber
and heat exchanger and will void your warranty.
f. Use your shop vac to vacuum ash from the flues.
NOTE: Avoid "packing" the ash in the back of the tubes by first vacuuming the flues before
pushing the flue brush down the flues.
g. Use a flue brush to thoroughly clean the flues.
h. Thoroughly vacuum any remaining ash residue from the flues.
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 fiberglass rope gasket.
NOTE: Make sure the fiberglass rope gasket is in good condition and the clean-out
door seals tightly. If the door does not seal tightly, replace damaged components.
k. Re-install the furnace components: clean-out door, clean-out panel, and stack.
NOTE: You may need to bleed air from the oil line before starting the burner. See Section 5
for the pertinent instructions.
l. Swing the burner into firing position. Install the lock-down nut and plug in the burner power
cable.
9-8
Operator's Manual: Model CB-1400
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: 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.

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:

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.

Fan Limit Control
Understanding the Operation of the Fan Limit Control
The fan limit control senses air temperature within the furnace cabinet. This control contains two switches: the
limit switch and the fan switch.
Fan Switch: The fan switch is normally open and provides power to the fan. When the fan limit
control senses "Fan On" temperature, the fan switch closes and starts the fan. 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.
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.

To Set Pointers on the Fan Limit Dial
1.
Turn OFF main power to the furnace.
2.
Remove the fan limit control cover.
3.
While holding the dial securely in place
with your thumb, move the pointer to
the desired setting.
ATTENTION: DO NOT rotate the dial when
setting the pointers. This severely damages the
control.

ORANGE WIRE (CONNECT TO FAN)
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 continues to run.
Once the fan limit control senses 170 degrees F, the
limit switch automatically resets and restarts the
burner.
NOTE: It is very important to avoid cycling
the burner on hi limit as described above. If
the hi limit activates, immediately check and
re-adjust burner settings.
ATTENTION: DO NOT change the fan limit
settings from the specified settings, or severe
damage to the furnace cabinet may occur.
