INSTALLLATION 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 suffi-
cient 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 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.

AIR SHUTTER SETTING
LOW FIRE SETTING
A) Loosen PRESSURE RELEASING SCREW (1). (One turn is sufficient). This permits the fuel pressure to bleed off
to the pump return port and the burner to operate continuously at the low fire rate.
B) Loosen RETAINING NUT (2).
C) Turn the ADJUSTING SCREW (3) until the top of the air shutter (9) is correctly positioned according to the Burner
Set-up Chart, column 5, on page 10.
D) Use instruments to establish the proper settings for maximum CO2 and a smoke reading of zero.
E) Hold ADJUSTING SCREW (3) in position and secure by tightening RETAINING NUT (2).
F) Retighten PRESSURE RELEASE SCREW (1).
Note:
The low fire pressure regulator is pre-set at the factory to 100 PSI (7 bar).
To vary or regulate this pressure it is necessary to attach a pressure gauge to the PRESSURE PORT (6).
Loosen the PRESSURE RELEASE SCREW (1) as in step A above. Regulate the pressure by turning the PRESSURE
REGULATING SCREW (5).
The corresponding pressure can be read on the pressure gauge attached to the PUMP PRESSURE PORT (6).
MAIN FLAME SETTING
A) Be sure that the burner is operating at high fire.
B) Set the pump pressure by attaching a pressure gauge to the Pressure port (6) and adjust the pressure by turning
the pressure regulator adjustment screw (10).
Loosen the RETAINING NUT (7), and turn the BOLT (8) in a counterclockwise direction until about 3/4 of an inch
of thread is visible. Using the setting taken from the Burner Set-up Chart, column 5, position the air shutter (9) so
that the top of the shutter is aligned with the proper index line indicated on the air intake side of the burner housing.
Holding the shutter in this position, turn ADJUSTING BOLT (8) in a clockwise direction until a resistance is met.
C) The final position of the air adjustment plate will vary on each installation. Use instruments to establish the proper
settings for maximum CO2 and 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 en-
sure proper test results.

DUCTED COMBUSTION AIR INTAKE APPLICATIONS
The “Ducted combustion air intake kit” (see P.N. 3002762 in the spare parts list - OPTIONAL), allows ducting of exter-
nal air directly into the burner. A 4” diameter air intake is provided in the kit.
The settings of the burner must be according to the BURNER SETUP CHART – AIR INTAKE APPLICATIONS below.
NOZZLES RECCOMANDED:
Monarch R-PLP, Delavan W-B, Danfoss S-B, Steinen SS-S, Hago P.
NOTE:
A 45° degree nozzle is suggested, however, a 60° degree nozzle may be used in cases where the flame is
unstable at light-off when operated at low ambient temperatures.
NOTES:
A) This kit is not suitable for direct vent applications.
B) Always try to minimize the length of the air intake pipe.
C) Reduce pipe length by 10 feet for every 90° elbow, 5 feet for every 45° elbow.
D) Reduce pipe length by 6 feet for the 4” to 6” pipe adapter (if used).
E) Air intake venting should be insulated 10 feet from air intake source with a minimum R7 foil lined insulation, to prevent
condensation or corrosion of air intake venting.
F) Use an approved type of air intake vacuum breaker and install it in the same room of the burner.
This device should be tested to prove that the vacuum breaker balancer is set correctly and, in the event of intake air
source being blocked, can provide enough combustion air for the burner. If the room where the burner is installed
cannot provide enough air or air quality is a concern, an additional air inlet source must be provided to this room.
G) On the outside of the wall, use an approved intake air hood, located above the snow line and in such way as to prevent
leaves and/or other debris from blocking the air flow. Refer to local codes for proper location of inlet.
To mount this kit on the burner, please follow the installation description given in the kit instruction sheet.
Use a 4” to 6” pipe adapter (not supplied in the kit) to use a 6” diameter pipe.
