Selecting a Location
Guidelines for Selecting a Location
The location you select for your furnace must allow the following:
• Unobstructed, even heat distribution.
• Safe, easy access for servicing.
• Unobstructed passage for shop vehicles and equipment.
• Proper clearances from combustibles. Verify according to your local safety codes.
• Adequate combustion air per local codes.
• Proper stack installation.
Adhere to the following minimum clearances from combustible surfaces and to provide adequate clearance for servicing:
• TOP ......................................................... 18"
• FRONT (burner side) .............................. 24"
• REAR (stack side) .................................. 36"
• LOUVER END ....................................... 60"
• BLOWER/FAN END ............................. 24"
• BOTTOM ............................................... 24"
• CHIMNEY CONNECTOR .................... 18"
WARNING: Your local codes may require that your furnace is mounted a minimum of eight (8)
feet off the ground if there is the possibility of gasoline fumes or other combustible or explosive
fumes in your shop area. Refer to NFPA-88B.
Determining Air Flow From the Furnace
One important consideration in selecting the proper location for your furnace is heat distribution, i.e.
how the air (heat) will circulate from your furnace. Depending on the type of furnace you ordered (Unit
Heater or Central Furnace), you will use one of two air flow configurations:
•
"Free air" circulation : this method is the easiest and most economical. In this case,
industrial-size ceiling fans may be installed to aid in efficient, even heat distribution.
NOTE: If the peak of your shop roof/ceiling is 14 feet or higher, Clean Burn recommends
the use of industrial-size ceiling fans to gently redistribute the heat from the furnace. A
minimum of one Clean Burn 56" Blade Industrial Ceiling Fan (C.B. part# 70003) or
equivalent is recommended for each 2000 square feet of heated shop space.
•
Ductwork (central furnace ONLY ): this method is more complex and requires careful
planning and additional investment for proper installation. If you plan to duct your furnace,
it is essential that qualified HVAC personnel design and install the ductwork system
according to the specifications provided in this section.

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.
Mounting the Furnace
After selecting a safe and appropriate location for
your furnace, construct the mounting system as
required by the location and the following
specifications.
Ceiling Mounting
CAUTION: Ensure that your furnace
mounting system can safely bear the
suspended weight of the furnace and allow safe
servicing of furnace components.

Determining the Type of Oil Tank
It is very important that you determine which type of oil tank your furnace will be using, as this will
determine the correct method for installing your oil pump and oil lines. Oil tanks are classified in three
categories as follows:
(1) Inside Above Ground Tank
(2) Outside Above Ground Tank
(3) Underground Tank
Ensure that your tank installation adheres to the following safety guidelines:
• The tank installation must meet all national and local codes. Consult your Clean Burn dealer
and local municipal authorities for more information if necessary.
• Use a minimum 250-gallon tank. DO NOT use a 55-gallon drum as a substitute for an
appropriate tank. The tank must be large enough to allow water, sludge, etc. to settle out of
the used oil.
• The tank must have a manual shut-off type valve on the side of the tank to allow the water,
sludge, etc. to be drained from the bottom of the tank.
• All unused openings in the tank must be plugged or capped off.
• The tank must be vented to the outside of the building using iron or steel pipe and fittings
with an approved vent cap.
1.
2.
Review the following three figures (4E/4F/4G) which illustrate the different types of oil
tank/pump installations, and select the one which matches your site's tank installation.
Carefully review the appropriate tank/pump installation details, including the pump installation
and specifications for the oil line installation. (Procedures for installing these components can be
found in the following sections.)

Installing the Oil Pump
After determining the type of oil tank your furnace installation will use, you can proceed by installing the
oil pump accordingly.
1.
2.
3.
4.
Study the specifications for oil pump installation provided in the appropriate tank/pump
installation diagram (either Figure 4E, 4F, or 4G).
Also refer to the oil pump installation diagram provided in this section (Figure 4H).
Adhere to the following guidelines:
• Install the oil pump in a location where it can be easily primed and serviced. Its location
must be protected from water and combustible fumes. DO NOT mount the pump in a
basement or on the floor.
• The oil pump can push the oil much further than it can suck the oil. It is therefore very
important that the pump be positioned as close to the oil tank as possible.
• Mount the pump inside the building to protect it from weather/exposure.
• Position the pump to minimize the height and length of the suction oil line (i.e. the oil
line from the pump to the tank). DO NOT exceed the following limits, or your pump will
not operate correctly:
Maximum suction line lift - 10 feet (or not to exceed 10" of vacuum)
Maximum horizontal run - 30 feet
• Measure the suction line lift and horizontal run for your installation and write this
information on the appropriate tank diagram in the spaces provided (either Figure 4E, 4F,
or 4G).
• The oil pump requires a single oil line. DO NOT install a return line to the tank unless
instructed to do so by your Clean Burn dealer.
• Whenever possible, mount the pump above the highest oil level in the tank, so the pump
is suction fed, not gravity or pressure fed.
ATTENTION: If your pump is gravity or pressure fed, DO NOT install check valves, or
severe damage to the oil pump seals and oil spillage will occur. Oil pressure at the pump
inlet may not exceed 3 psi. Refer to NFPA-31.
Install the oil pump according to the instructions and specifications provided in the diagrams.

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 oil 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

Operator's Manual: Models CB-1400, CB-1800, and CB-2800
Installing the Oil Lines
Your furnace installation requires two oil lines:
(1) Suction oil line: oil line and suction line components from the tank to the pump.
(2) Pressure oil line: oil line from the pump to the connector block on the furnace.
Procedures and specifications for the installation of the oil lines follow.
ATTENTION: Be sure to purchase copper tubing which is sized correctly for your installation.
Undersizing of oil lines restricts oil flow and results in poor furnace performance. Refer to the tables in
this section listing the proper sizing of the suction and pressure oil lines.
Installing the Suction Oil Line
1.
2.
3.
Study the specifications on the appropriate Tank/Pump installation diagram (either Figure 4E,
4F, or 4G).
Make sure you have purchased all the necessary fittings to complete the installation correctly.
Install the fittings and components as shown in the appropriate Tank/Pump installation diagram.
Also adhere to the following guidelines:
• DO NOT exceed line lengths and suction limits of the pump. Keep the suction line and
suction lift as short as posssible.
Maximum suction line lift - 10 feet (or not to exceed 10" of vacuum)
Maximum horizontal run - 30 feet
• Use properly sized copper tubing according to the following chart:
Type of Tank
Inside Tank
Outside Tank
Underground Tank
Minimum Size of Copper Tubing*
5/8" O.D.
3/4" O.D.
3/4" O.D.
*NOTE: Maximum allowable size of tubing is 1" O.D. for all
types of tanks.
•
•
•
Ensure that the suction line is 100% airtight. The pump cannot properly suck oil from the
tank if there are any leaks in the suction oil line. Air leaks in the suction line due to improper
installation will result in repeated burner shutdown and unnecessary service calls.
Use only good flare fittings. DO NOT use compression fittings or pipe unions on the suction
line. The use of these inappropriate materials on the suction line will result in air leaks and
burner shutdown.
Seal each threaded fitting with #2 Permatex non-hardening gasket sealer or equivalent. DO
NOT use teflon tape. Teflon residues will plug vital pump and burner components and will
void your warranty.
4-17
Operator's Manual: Models CB-1400, CB-1800, and CB-2800
Installing the Suction Oil Line (continued)
4.
5.
Install the canister filter in the suction line according to the specifications on the appropriate
Tank/Pump diagram (either Figure 4E, 4F, or 4G).
NOTE: DO NOT install the canister filter in the pressure oil line. This filter must be
installed in the suction oil line to protect the pump head. Ensure that the filter can be easily
accessed for cleaning.
Install the vacuum gauge in one of the ports of the canister filter. Ensure that all fittings on the
canister filter are 100% airtight.
Installing the Pressure Oil Line
1.
2.
3.
Study the specifications on the appropriate Tank/Pump installation diagram (either Figure 4E,
4F, or 4G).
Make sure you have purchased all the necessary fittings to complete the installation correctly.
Install the fittings and components as shown in the appropriate Tank/Pump installation diagram.
Also adhere to the following guidelines:
• Properly size the pressure oil line according to the following chart:
Length of Pressure Line
Minimum Size of Copper Tubing
Length up to 50 feet
Length up to 100 feet
Length up to 200 feet
1/2" O.D.*
5/8" O.D.*
3/4" O.D.*
*Diameter of copper tubing must be maintained for full line length.
•
Local codes may require the installation of "oil thermo cut-off" safety valves. Be sure to
check all appropriate codes to ensure compliance.
Installing the Compressed Air Line
NOTE: Your air compressor system must supply air pressure to the furnace with the following
requirements:
• 50 psi
• 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.
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 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 50 psi.
ATTENTION: DO NOT feed full shop air pressure to the burner or damage to burner
components may occur.
4-18
Operator's Manual: Models CB-1400, CB-1800, and CB-2800
Installing the Compressed Air Line (continued)
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.
NOTE: 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
(2) "Class A" stack through the sidewall and up the side of the building
Figures 4I and 4J illustrate these stack designs. Choose the stack design which is appropriate for your
furnace installation and review all specifications provided in the Figure. When designing your stack,
adhere to the following specifications:
• Models CB-1400/CB-1800/CB-2800 require minimum 8" I.D. stack components.
• Ensure that the vertical stack height is at least 10 feet. 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 or 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 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 concerning exhaust fans and
proper make up air.
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. All single wall
stack components must be located a minimum 18 inches from combustibles.
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: IMPORTANT for Canadian Installations - Local codes may require the installation of
a clean-out tee.

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#71074).
Install the barometric damper in the opening of the tee. Use a small spirit level to make sure that
it is properly level as shown.
Install one self-tapping screw at the BOTTOM of the barometric damper to hold it in place.
DO NOT install this screw at the top 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
CAUTION: When running the stack through your ceiling, roof, or sidewall, you must use a
proper insulated "Class A" penetration with a stainless steel liner. DO NOT run single-wall stack
through your ceilng, roof or sidewall. Single-wall penetrations do not meet safety codes and may create
a fire hazard. Provide proper clearances to combustibles per all applicable codes.
1.
2.
Refer to Figure 4I/4J as needed.
Follow the installation instructions provided by the stack manufacturer.
Installing the Exterior Stack
ATTENTION: All exterior stack pieces must be insulated "Class A" ("all fuel") stack components with
a stainless steel liner. DO NOT use "Class B" natural gas stack components. 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 4I or 4J 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 4I or 4J as needed. Your stack cap should be classified as: "Class A"
non-restrictive, "fuel-oil type".
Install the stack cap according to the manufacturer's instructions.

4.
5.
Select a location for the thermostat on an interior wall away from the furnace and cold drafts.
Run "two wire" (minimum 18 gauge) thermostat cable between the burner and the thermostat.
Remove the yellow jumper wire from the "T" terminals of the oil primary control. Save this
jumper wire for use during pump priming.
Connect the thermostat wires to the two "T" terminals on the oil primary control.
Follow the manufacturer's instructions to wire the thermostat.
Inspecting the Furnace Installation
Following completion of all installation activities described in this chapter, the furnace should be inspected by qualified personnel before firing. This ensures that your installation meets all applicable
national and local codes and allows for any deficiencies to be corrected before furnace startup. Improper
installation may void your warranty.

SECTION 5: OIL PUMP PRIMING
Understanding Oil Pump Priming
Preparing your Clean Burn furnace for operation begins with priming the oil pump. This activity
involves a series of separate procedures as follows:
(1) Preparing the Canister Filter for Pump Priming
(2) Preparing the Pump for Pump Priming
(3) Preparing the Burner for Pump Priming
(4) Activating the Pump
(5) Establishing Proper Oil Flow
(6) Flushing the Oil Lines
(7) Adjusting the Pump Pressure
NOTE: 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
Rags
Two containers (minimum one-gallon)
Medium straight-blade screwdriver
5-1
Operator's Manual: Models CB-1400, CB-1800, and CB-2800
Preparing the Canister Filter for Pump Priming
ATTENTION: Fill the canister filter with used oil so the pump gears are charged with oil during the
priming procedure. DO NOT use new motor oil; it will probably not ignite at the burner. DO NOT run
the pump with dry gears, or the pump will not prime and damage may occur.
1.
Refer to Figure 5A.
2.
Remove the four (4) bolts holding the canister bowl in place, then remove the bowl.
3.
Check the condition of the filter element and O-ring.
4.
Make sure the O-ring is in the groove on the top of the filter element. Push the element into
position on the filter body.
5.
Fill the canister with used oil to prevent the pump from running dry during priming.
6.
Check the condition of the canister O-ring, and re-install the canister. Tighten the four canister
bolts evenly to ensure that the canister filter is 100% airtight.

Preparing the Burner for Pump Priming
NOTE: It is necessary to allow the burner to warm up at least 15 minutes prior to activating the burner
during the pump priming sequence. The proving switch on the preheater block will not allow the burner
to start until the block is hot.
1.
Turn the switch on the wall thermostat to OFF.
NOTE: If your thermostat does not have an OFF setting, disconnect one thermostat wire so the
burner will not run.
2.
Turn the main power to the furnace ON.
3.
Refer to Figure 5C.
4.
Disconnect the oil line at the connector block on the furnace.
5.
Position a one-gallon container (minimum) to catch oil which will flow from the disconnected oil
line during pump priming.
NOTE: It is important to thorougly flush the oil line during pump priming so that no dirt/debris
is fed to the burner.
6.
Loosen the locking nut on the oil regulator, and turn the knob two to three full turns counter
clockwise so the oil regulator is completely shut off.

Activating the Pump
IMPORTANT NOTE: 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.

Refer to Figure 5D, Step 1.
Locate the yellow jumper wire which you removed and saved during installation of the wall
thermostat.
Connect the jumper wire to one "F" terminal on the primary control.
Refer to Figure 5D, Step 2.
Turn the switch on the wall thermostat to HEAT, and adjust the thermostat above room
temperature.
The burner should start running.
Immediately turn the knob on the air regulator clockwise until the air gauge registers 15 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.
The pump should start running.
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 burner and pump until proper oil flow has been established and the oil lines have been
completely flushed out. (See the following procedures for specific instructions.)

Establishing Proper Oil Flow at the Pump
1.
2.
3.
Within one minute after opening the bleeder port, oil should be sputtering from the port. Make
sure the container is positioned to catch the oil flowing from the port.
ATTENTION: If no oil flows within one minute, shut the pump off and call your Clean Burn
dealer. DO NOT run the pump "dry"--doing so may damage the gear set.
Observe the oil flow at the bleeder port until a steady stream (no fluctuations or sputtering) is
achieved. Bleed approximately one quart of oil from the open port to ensure an airtight suction
line.
NOTE: If the oil stream continues to fluctuate or sputter, there is a leak(s) in the suction
line. Any leak(s) in the suction line must be repaired to ensure that the suction line is 100%
airtight.
Close the port with a 3/8" wrench and tighten completely.
Flushing the Oil Lines
1.
2.
3.
4.
Go back to the burner (at the disconnected oil line). Observe a steady oil flow until one gallon
has been collected; this ensures that all air and debris have been flushed from the oil line.
Turn the power OFF so the burner and pump motors stop running.
Re-connect the oil line to the connector block.
Remove the jumper wire from the "F" terminals, and make sure the cad cell wires are now
connected to the "F" terminals as illustrated in Figure 5D, Step 3. Save the jumper wire for
future pump priming.
Adjusting the Pump Pressure
NOTE: It is not necessary to adjust pump pressure for most furnace installations. Adjust the pump
pressure only if either of the following conditions exist:
• The distance between the pump and the furnace is less than 50 feet.
• You are burning light viscosity oil such as #2 fuel oil. (In this case, you may also need to
install a nozzle with a smaller orifice. Contact your Clean Burn dealer before proceeding.)
1.
2.
3.
Refer to Figure 5B.
Turn the set screw counterclockwise with a small, straight-blade screwdriver until the screw is
flush with the nipple. DO NOT back the set screw out more than this!
Turn the adjustment screw clockwise one full turn to set the pump pressure at approximately
20 psi.

SECTION 6: STARTING AND ADJUSTING THE BURNER
Understanding Burner Startup and Adjustment
Starting and adjusting the burner involves a series of separate procedures which must be accomplished
in sequence without interruption. Review all the procedures before attempting burner startup and
adjustment, paying careful attention to safety information statements.
Preparing the Burner for Startup
1.
2.
3.
4.
5.
Turn the switch on the wall thermostat OFF.
NOTE: If your thermostat does not have an OFF setting, disconnect one thermostat wire so
the burner will not run.
Turn the main power to the furnace ON.
Wait at least 15 minutes until the preheater block is thoroughly warmed up. (Feel the back of the
burner box to make sure the preheater is sufficiently warm. The proving switch on the preheater
block will not allow the burner to start until the block is hot.)
NOTE: The preheater block will remain warm as long as power is supplied to the burner. If the
main power supply is ever turned OFF, you must wait at least 15 minutes until the preheater
block is thoroughly warm before starting the burner.
Refer to Figure 6A to locate
the oil and air regulators.
Loosen the locking nuts on
the oil and air regulators.
Turn the adjustment knobs on
the oil and air regulators
counterclockwise until 1/2"
of the threads on the knobs
are exposed. DO NOT back
the knobs all the way out.
NOTE: The air and oil
gauges will not show any

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.

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.
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.
3.
Within ten seconds, turn the knob on the oil regulator clockwise until the oil regulator gauge
shows 1 psi and the burner ignites. Do not exceed 1 psi at this time. Instructions are provided
later in this section for adjusting the oil regulator to the proper flame length.
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.
4.
Adjusting the Oil Regulator:
While adjusting the oil regulator, visually inspect the
CAUTION
flame length through the observation port. Refer to
WHEN OPENING INSPECTION PORT
Figure 6B for an illustration of the desired flame length.
The flame should extend no more than one-half of the
PORT MAY BE HOT

way down the combustion chamber.
WEAR
SAFETY GOGGLES
WARNING: The observation port gets hot as the
KEEP
FACE AWAY
burner fires. To avoid personal injury, always wear
OPEN PORT SLOWLY
heavy work gloves and safety glasses when opening the port
and viewing the flame.
NOTE: The CB525-S2 burner features a unique oil regulator system which regulates the oil after it has
been heated to 140 degrees F. At this temperature, the difference in viscosity between various used oils
is minimal, and the need for adjusting the oil regulator is significantly reduced. Additionally, this burner
allows for fine tuning to accommodate the particular blend of used oils being burned. It is also designed
to operate at low ambient temperatures with minimal adjustment.
Correct Maximum Flame Adjustment
(Proper Oil and Air Pressure):
• Flame goes half of the way down the
combustion chamber.
• Flame does not touch back or walls of
combustion chamber.
Incorrect Flame Adjustment
(Oil Pressure Too High):
• Flame must not touch back or walls of
combustion chamber.
Incorrect Flame Adjustment
(Air Pressure Too High):
• Ensure proper air pressure setting.

Starting the Burner (continued)
5.
6.
7.
8.
Check the flame length after the burner has fired for 15 minutes. If necessary, adjust the oil
regulator to fine tune the flame.
Tighten the locking nuts on the oil regulator and the air regulator.
NOTE: After initial startup, check the flame length at least weekly and readjust as necessary.
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, the oil you are burning requires MORE combustion air.
OPEN the air band 1/8" to 1/4", and re-check the flame for the proper characteristics.
• Re-check the flame after five minutes--you should see a yellow-white flame with sharp
tips and no "sparkles."
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/Blower Motor
NOTE: It is important to verify that the fan/blower motor operates correctly to ensure that the fan limit
control is properly cycling the fan/blower motor as described below. Also refer to Appendix A at the
back of the manual for additional information on the fan limit control.
1.
Start the burner and adjust it as described previously in this section.
2.
The fan/blower motor will not start until the burner has been running for 5 to 15 minutes to heat
up the combustion chamber and heat exchanger. At this point, the fan limit control will activate
the fan/blower motor.
3.
Once the fan/ blower motor has activated, turn the burner off by turning the wall thermostat to
OFF.
4.
With the burner off, the fan/blower motor should continue to run for 5 to 10 minutes until the
combustion chamber is cooled down. The fan limit control will then shut off the fan/blower
motor.
WARNING: If the fan/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.

Operator's Manual: Models CB-1400, CB-1800, and CB-2800
SECTION 7: RESETTING THE OIL PRIMARY CONTROL
Understanding the Oil Primary Control
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.

SECTION 8: ADJUSTING THE DRAFT OVER FIRE
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 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 Over Fire
WARNING: Correct draft over fire is
essential for the proper and safe operation
of your furnace.
Your furnace is equipped with an observation/
draft reading port to check draft over fire. 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 (i.e. -.06 to
-.12) sucks the heat from the furnace and
results in abnormally high stack
temperature.

With the burner running, check the draft
overfire with a draft gauge.
As shown in Figure 8B, adjust the weight
on the flapper to obtain a consistent
-.02 w.c. draft overfire. Turn the weight
COUNTERCLOCKWISE to increase draft
(i.e. draft increases as the flapper closes).
Turn the weight CLOCKWISE to decrease
draft (i.e. draft decreases as the flapper
opens).
Tighten the locking nut to securely hold
the weight in position.

Solving Draft Overfire Problems
WARNING: If you cannot achieve proper draft overfire, do not operate your furnace!
Contact your Clean Burn dealer for assistance.
ATTENTION: Backdraft must be resolved or your furnace will not operate correctly!
Under backdraft conditions, draft overfire readings will show positive pressure in the combustion
chamber. Backdraft means that oil spray, combustion products, and heat are blown back against the
burner. Backdraft results in oil-fouled retention heads and electrodes. Severe backdraft will force heat
back against the burner and result in heat damage to the cad cell and transformer.
Backdraft is caused by the following conditions:
• Poor draft caused by improper stack design. (See Section 4.)
• Poor draft caused by improper adjustment of the barometric damper.
• Incorrect combustion air band setting on the burner. (See Section 6.)
• Furnace flues are plugged with ash. (See Section 9.)
• Clean-out gasket on clean-out doors is out of position. (See Section 9.)
• Exhaust fans in your building are sucking gases down the stack.
8-2
Operator's Manual: Models CB-1400, CB-1800, and CB-2800
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 (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
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) With all exhaust fans running, open one of the large bay doors so that it is just 2 feet
open. Position a helper at this door.
(b) Start the furnace and check for proper -.02 w.c. draft overfire.
(c) As you watch the draft gauge, instruct your helper to slowly close the large bay door.
When the draft overfire is affected, stop closing the door.
(d) Open the large bay door just enough to allow the draft overfire to return to a proper
-.02 w.c. The size of this opening represents the approximate size of the make-up air
louver required.
(e) Measure the size of the opening and calculate the square inches. Select a make-up air
louver that is at least 10% larger than this opening.
Example of Calculations for Sizing Make-up Air Louver
1. Opening Size
12' (144") x 1' (12") = 12 square feet (1728 (square inches)
2. Add 10%
1728 square inches x 1.1 = 2000 square inches
3. Louver Size
Select 48" x 48" louver = 2304 square inches
(Installation instructions are provided on the next page)

Operator's Manual: Models CB-1400, CB-1800, and CB-2800
Installing the Make-up Air Louver
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
Maintaining your Clean Burn furnace is an important activity which includes several periodic maintenance activities and an annual burner tune-up...all are necessary to keep your furnace running in peak
condition. 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 maintenance activities which should be performed on the furnace
at the intervals indicated. Instructions/procedures for these activities are included in this chapter.
Maintenance Activity
Cleaning the canister filter
Cleaning out ash
Cleaning the check valve/screen
Cleaning water/sludge out of tank
Annual burner tune-up
Interval
Before vacuum gauge reads 10" HG of vacuum
At least twice a year; more often with heavy use
At least once a year
At least once a year
At least once a year
NOTE: IMPORTANT! Record all maintenance activities in the Maintenance Record provided in the
Appendixes.
Annual Burner Tune-up
Your Clean Burn furnace requires annual preventative maintenance--similar to an automotive tune-up-to keep it running in peak condition. Contact your local Clean Burn dealer to schedule the annual
preventative maintenance which is usually (preferably) performed during warm weather to prepare the
furnace for the next heating season. The burner tune-up should be performed by Clean Burn certified
technicians.
9-1
Operator's Manual: Models CB-1400, CB-1800, and CB-2800
Cleaning the Canister Filter
NOTE: Never operate your furnace with more than 10" HG of vacuum on the suction side of the pump.
High vacuum separates air from the oil and results in erratic burner operation.
The following protective gear should be worn when cleaning the filter:
• Rubber gloves
• Safety goggles
1.
Close the ball valve adjacent to the filter.
2.
Position a container under the filter.
3.
Unscrew the four bolts to drain the oil from the canister.
4.
Remove the canister bowl.
5.
Clean the screen and the bowl in a parts washer.
6.
Referring to Figure 9A, examine the filter components as you reassemble them.
7.
Check the condition of the O-rings. Replace any that are cracked or worn.
8.
Ensure that the canister filter is 100% airtight by firmly tightening the four bolts.
9.
Open the ball valve. Refer to Sections 5 and 6 for instructions on priming the pump and starting
the burner.
USE A RATCHET WITH A 6-INCH EXTENSION AND
3/16-INCH "ALLEN" SOCKET TO REMOVE THE
FOUR "ALLEN" BOLTS

Operator's Manual: Models CB-1400, CB-1800, and CB-2800
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. 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. 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.
The following protective gear should be worn when cleaning the ash:
• Respirator for fine particles
•Rubber gloves
• Safety goggles
•Protective clothing
1.
2.
3.
Ensure that power has been turned OFF, and all "hot" components have been allowed to cool
sufficiently. Allow at least one hour for the ceramic 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.

the combustion chamber.
e. Check the color of the
ash--it should be light
gray or tan.
ATTENTION: White
ash indicates excessive air
pressure. Black ash or
soot indicates too
much oil pressure. If
these conditions exist,
call your Clean Burn
dealer. DO NOT overfire
your furnace by turning
up the compressed air
and/or oil pressure.

will void your warranty.
f. Use your shop vac to
vacuum ash from the flues. Figure 9B - Accessing the Combustion Chamber for Cleaning
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.

Operator's Manual: Models CB-1400, CB-1800, and CB-2800
Cleaning the Ash (continued)
j. Inspect the fiberglass rope gasket.
NOTE: Make sure the fiberglass rope gasket is in good condition and the clean-out
door(s) seal(s) tightly. If the door(s) does not seal tightly, replace damaged components.
k. Re-install the furnace components: clean-out door(s), cross brace (CB-2800), 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.
Cleaning the Check Valve
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
1.
Refer to Figure 9C. Remove the standpipe from the tank.
2.
Remove the check valve and filter. Clean these components in a parts washer.
3.
Check the operation of the check valve. The valve must seat so it is airtight to hold pump prime.
4.
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.
5.
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.
End of Season Maintenance
ATTENTION: Turn main power to your furnace OFF at the end of the heating season. EPA regulations allow your used oil to be burned only for "heat recovery." DO NOT operate your furnace during
warm weather just to burn oil, or severe damage to the combustion chamber/heat exchanger may occur.
Contact your local Clean Burn dealer to schedule your annual burner tune-up. Allow only trained,
authorized service personnel to service your burner.

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.

Unscrew the stem from the nozzle head.
Spray WD-40 or equivalent through the orifice to thoroughly remove any blockage.
ATTENTION: 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.
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.

Oil Pump Components (continued)
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.
BALL VALVE
IMPORTANT NOTE: For the pump to pull and hold
VACUUM GAUGE
vacuum, it is critical that all fittings are airtight.
Check the cover bolts, the 1/4" plug in the return port
and the acorn nut (on older style pumps only). If any
FIGURE A6 - Oil Pump System
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.
Refer to Section 5: Oil Pump Priming in this manual. Follow the instructions to prime the oil
pump. NOTE: The oil pump will not pull a vacuum if the pump is dry. There must be oil in the
gears of the pump before the pump can pull a vacuum.
2.
With the pump running, open the bleeder two to three full turns, and make sure that oil is flowing
from the bleeder. DO NOT close the bleeder yet.
3.
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.
4.
The vacuum should increase within 15 seconds to 20 to 25 inches of vacuum. When the vacuum
gauge reads 20 to 25 inches of vacuum, first close and tighten the bleeder, then turn the pump
off.
NOTE: If the pump will not pull at least 20 inches of vacuum, there is a very serious suction
leak or the pump is damaged.
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.
IMPORTANT: 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.

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 (or blower). When the fan
limit control senses "Fan On" temperature, the fan switch closes and starts the fan (or blower). When
the wall thermostat is satisfied and the burner shuts off, the fan continues to run until the fan limit
control senses the "Fan Off" temperature. At this temperature, the fan switch opens and shuts off the fan
(or blower).
NOTE: The fan limit control has a white fan switch button. Make sure the white button is pulled OUT
for automatic (normal) operation. When the button is pushed in (manual setting), the fan will run
continuously.
Limit Switch: The limit switch is normally
closed and provides power to the oil primary

and the burner stops running. The fan (or

automatically resets and restarts the burner.
