INSTALLATION 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 room is enclosed. It may be necessary to create a window to permit sufficient air to
enter the boiler 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 con-
nected 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.
The burner settings used in this manual were obtained under laboratory conditions and may vary

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 to-
wards 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 1/4” (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 amu-
let or cera-felt sleeve be used on the end cone to help re-
duce 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 diam-
eter. Please refer to amulet instructions in regards to in-
stalling 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 (5) 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 com-
bustion chamber of the heating unit is suggested. Dimen-
sion “B” should be at least 1/4 inch (see drawing).
METHOD 2 – PEDESTAL MOUNT
Secure the MOUNTING FLANGE to MOUNTING PED-
ESTAL 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 ped-
estal tube and securing brackets to the floor.
WHEN THE COMBUSTION CHAM-
BER 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 OPER-
ATION OR SHUTDOWN WILL DAMAGE THE
END CONE. IF HIGH END CONE TEMPERA-
TURES 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.

1) Loosen the bleeder valve (A).
2) Disconnect nozzle oil supply line at the pump nozzleport (B).
3) Attach a flexible plastic tube to the pump nozzle, port directing
the oil flow into a bucket.
4) Loosen the screw(s) securing the air tube cover, allowing it to
be removed freely.
5) Holding the air tube cover in its proper location start the burner.
6) When the solenoid valve is engaged approximately 10 seconds
after starting, remove the air tube cover and shine a light
source on the photocell, allowing it to see false light.
7) Run the burner until the fuel pump has been purged of air, then tighten the bleeder valve and immediately
shut down the burner.
8) Reinstall the air tube cover and nozzle line.
9) The burner can now be started normally.
Omitting steps 2 and 3 will result in a collection of unburned oil in the combustion chamber creating a
hazardous situation upon burner startup.
B) TWO LINE (LIFT SYSTEM)
Turn off the main power source to the burner and remove the air tube cover. Shines a light source on the photocell
(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.
SETTING THE AIR ADJUSTMENT PLATE
A) The initial air damper setting is made by turning screw (2) until
the top edge of the air damper (3) is aligned with the number ac-
cording to the burner setup chart.
B) Further adjustments can be made with the burner cover in place
by removing plastic plug on the top right hand side of the cover.
Turn the screw counter clockwise (+ indicator) to increase com-
bustion air, turn the screw clockwise (- indicator) to decrease
combustion air.
C) The final position of the air damper will vary on each installation.
Use instruments to establish the proper settings for maximum
CO2and a smoke reading of zero.
NOTE:
Variations in flue gas, smoke, CO2, and temperature readings may
be experienced when the burner cover is put in place.
Therefore, the burner cover must be in place when making the final
combustion instrument readings, to ensure proper test results.
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 WILL OCCUR.

IMPORTANT
The following charts indicate initial setting with combustion air at 20ºC (68ºF).
MODEL BF3 BURNER SETUP CHART
MODEL BF5 BURNER SETUP CHART
- Actual input values given in above table are based on zero (0) chamber pressure, fired in Riello Canada Inc. Test
Lab DIN (small) test boiler (chamber length 17”, chamber diameter of 11”). Input values calculated using pump pres-
sures listed above in the set-up table. Some variations will occur depending on application. This above set-up table
is used to assist in the initial set-up only. Proper test equipment must be used to set the burner up properly.
- Please refer to appliance literature or recommendation regarding nozzle size, spray pattern and spray angle. If no
suggestions or literature are given, using above set-up table for desired input value set burner to table setting until
burner is firing then make suitable adjustments to burner to achieve desirable combustion results.
