MOUNTING THE BURNER
TO THE BOILER OR FURNACE
There are two possible methods to mount the burner, depending on the individual application. These
are:
1) Universal flange bolted to Boiler/Furnace unit.
2) Universal flange mounted to optional Pedestal mount, where flange mounting direct to appliance is
not possible. Pedestal kit must be ordered separately.
METHOD 1 –UNIVERSAL MOUNTING FLANGE
A) Slide the UNIVERSAL MOUNTING FLANGE (1) over the end cone assembly with the flat flange
surface towards the heating unit.
B) Secure the UNIVERSAL MOUNTING FLANGE to the AIR TUBE by tightening the ALLEN
BOLT (2). Be sure that the MOUNTING FLANGE is properly positioned. The outer edge of the
END CONE will be at least ¼” (6.5 mm) back from the inside wall of the refractory chamber or
inside wall of the combustion chamber (see dimension B above). The measured length (A) is to
include the MOUNTING GASKET (3) and FLANGE.
C) For dry based appliances it is suggested that an amulet or cera-felt sleeve be used on the end cone
to help reduce the risk of end cone burn-off. This amulet also provides an additional benefit of
sealing the chamber air tube hole when this hole is larger then our air tube diameter. Please refer to
amulet instructions in regards to installing amulet to the burners air tube end cone.

D) The burner can now be attached to the heating unit by inserting the AIR TUBE through the
BURNER ACCESS HOLE (6) and into the appliance, making sure the MOUNTING FLANGE
lines up with the appliance studs (6). Secure the burner in place using nuts (4).
A visual verification of the air tube insertion into the combustion chamber of the heating unit is
suggested. Dimension “B” should be at least ¼ inch (see drawing).
METHOD 2 –PEDESTAL MOUNT
Secure the MOUNTING FLANGE to MOUNTING PEDESTAL using the hardware provided with the
pedestal. Secure burner to MOUNTING FLANGE as in METHOD 1.
NOTE: It is suggested that the pedestal be anchored in position on the floor by installing brackets over
the pedestal tube and securing brackets to the floor.
WARNING: WHEN THE COMBUSTION CHAMBER IS LINED WITH A REFRACTORY
MATERIAL, IT IS IMPERATIVE THAT THE END CONE NOT PROTRUDE INTO THE
CHAMBER AREA, AS EXCESSIVE HEAT AT BURNER END CONE DURING OPERATION OR
SHUTDOWN WILL DAMAGE THE END CONE. IF HIGH END CONE TEMPERATURES ARE A
CONCERN USING A CERA-FELT SLEEVE OR, AMULET OVER THE END CONE COULD
HELP REDUCE THE RISK OF BURN-OFF THE END CONE.
ELECTRICAL CONNECTIONS
It is advisable to leave the control box off the sub-base while completing the electrical connections to
the burner.
1) Electrical connector
2) Earth ground conductor terminal
The burner may be controlled using either a DIRECT LINE
VOLTAGE control circuit (120V AC 60 cycle) OR a LOW
VOLTAGE control (24V AC 60 cycle) using models Riello or
Honeywell R8038A 24v relays.
Following the wiring diagram on the next page, make
electrical connections to burner. All wiring must be done in
accordance with existing electrical codes, both National and
Local.
WARNING: DO NOT activate burner until proper oil line connections have been made, or failure of
the pump shaft seal may occur.

WARNING: The vacuum should not exceed 11.44 inches of mercury.
WARNING: An external, appropriately listed and certified oil filter must be placed in the fuel
line between the fuel tank and the burner pump.
PUMP PURGE
NOTE: To protect the pump gears. It is advisable to lubricate the pump before purge all air out of oil
line(s) system. Apply oil through the VACUUM PORT.
1) SINGLE LINE (GRAVITY SYSTEM)
Turn off all power to burner/appliance, and then attach a hose over bleeder plug fitting put other end of
hose into a bucket. Loosen bleeder plug, when oil comes out of bleeder plug and appears clear tighten
bleeder port plug, and remove hose. The burner should have purge all air of pump, and oil line and
burner is ready to operate.
2) TWO LINE (LIFT SYSTEM) 2 options
A) Turn off the main power source to the burner and
remove the air tube cover. Shine a light source on the
photocell on the control box (now visible where the air
tube cover was removed), return power to the burner
and activate the burner. With the light source in place,
the burner will operate in prepurge only. Once the
burner is purged, turn off the power source and replace
the air tube cover. Return power to the burner. The
burner is now ready to operate.
B) Turn off the main power source to the burner/
appliance and then remove control box module. Get a
jumper wire and jumper sub-base terminals # 5 & # 6, this will operate the motor and pump only
with the control module off. Attach a hose over the bleeder port fitting and put the other end into a
bucket. Restore power and run burner without control box module until oil flows out of bleeder port
fitting and appears to be clear. Remove power and reinstall control box module, now the burner is
ready to operate.
ATTENTION: It is important that the fuel line be completely sealed and free from air leaks or
any internal blockages.
WARNING! WHEN THE BYPASS PLUG IS INSTALLED, A TWO-PIPE SYSTEM MUST BE
USED OR FAILURE OF THE PUMP SHAFT SEAL WILL OCCUR.

A TYPICAL LAYOUT FOR BF BURNER INTAKE AIR
A) Use an approved air intake kit.
B) Always keep intake air run to the minimum.
C) Maximum intake air run of 4 (inch) diameter, flexible or rigid type of venting = 100’
D) Reduce intake air length by 10’ for every 90° elbow used. 5’ for every 45° elbow used.
E) It is suggested that air intake venting be insulated with R7 (min) foil lined insulation a minimum of 10’ from
air intake source. (Prevent condensation or corrosion of intake air venting)
F) Used approved type of intake air vacuum breaker and to be installed in the same room and the burner, for the
event of intake air source being blocked, this device should be tested to prove that in the event of intake air
source is blocked that the vacuum breaker balancer is set correctly and can provide sufficient air for
combustion for the burner. If the room that the burner is installed into cannot provide enough air or air
quality is a concern, an additional air inlet source will have to be providing to this room.

PRECAUTIONS
AIR FOR COMBUSTION
Do not install burner in room with insufficient air for combustion. Be sure there is an adequate air
supply for combustion if the boiler/furnace room is enclosed. It may be necessary to create a window to
permit sufficient air to enter the boiler/furnace room. The installer must follow local ordinances in this
regard.
CANADA: It is suggested that the installer follow CSA standard B139.
USA: It is suggested that the installer follow NFPA manual #31.
CHIMNEY
Be sure chimney is sufficient to handle the exhaust gases. It is recommended that only the burner be
connected to the chimney. Be sure that it is clean and clear of obstructions.
OIL FILTER
An external oil filter is REQUIRED, even though there is an internal strainer in the pump. The filter
should be replaced at least once a year, and the filter container should be thoroughly cleaned prior to
installing a new filter cartridge.
DRAFT
Follow the instructions furnished with the heating appliance.
The pressure in the combustion area should be kept as close to zero as possible. The burner will operate
with a slight draft or pressure in the chamber.
ELECTRICAL CONNECTIONS
CANADA
All electrical connections should be done in accordance with the C.E.C. Part 1, and all local codes. The
system should be grounded.
USA
All electrical connections should be done in accordance with the National Electrical Code, and all local
ordinances. The system should be grounded.
CONTROL BURNER OPERATION
Check out the burner and explain its operation to the homeowner. Be sure to leave the Owner’s
Instruction sheet with the homeowner.
FIRE EXTINGUISHER
If required by local codes, install an approved fire extinguisher.
ELECTRICAL CONNECTIONS
. In most localities, a number 14 wire should be used inside a metal conduit. The system should be
grounded. A service switch should be placed close to the burner on a fireproof wall in an easily
accessible location.
