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/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 sys-
tem should be grounded.
USA All electrical connections should be done in accordance with the National Electrical Code, and all local ordi-
nances. 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.

INITIAL SET-UP
A) Remove burner and air tube from cartons. Check parts list (inside cover) to ensure all parts are present.
B) Remove burner cover by loosing the three screws securing it. Remove control box and air tube cover.
C) Remove drawer assembly from air tube, insert nozzle and set Turbulator adjustment for specific input required, then
set aside.
D) Mount air tube to burner chassis.
ASSEMBLY OF AIR TUBE TO
BURNER CHASSIS
The air tube and drawer assembly are
shipped in a carton separate from the burner
chassis. Choose the proper air tube length to
obtain the tube insertion for the specific in-
stallation.
A) Remove the AIR TUBE and BURNER
CHASSIS from their respective cartons.
B) Remove the DRAWER ASSEMBLY (1)
from inside the AIR TUBE by loosening
the screw (2). Carefully pull the DRAWER ASSEMBLY out of the AIR TUBE, install the required nozzle (see
page 10) and set aside.
C) Remove the two BOLTS (3) from FRONT PLATE (4) of the BURNER CHASSIS. Align the two holes on the AIR
TUBE HOLDING PATE (5) with the two holes on the BURNER CHASSIS FRONT PLATE with the BOLTS (3)
removed. Replace the BOLTS and fingers tighten only. Re-install DRAWER ASSEMBLY into AIR TUBE.
Tighten SCREW (2) securely.
D) Tighten the two bolts (3) securely.
MOUNTING THE BURNER TO THE BOILER OR FURNACE
There are three possible methods to mount the burner, depending on the individual application. These are:
1) Universal flange bolted to Boiler/Furnace unit.
2) Semi-flange collar bolted to Boiler/Furnace unit.
3) Universal flange mounted to optional Pedestal mount, where flange mounting direct to appliance is not possible.
Pedestal kit must be ordered separately.

A) Insert the two BOLTS (1) into the UNIVERSAL MOUNTING FLANGE (10) from the flat side, ensuring the bolt heads
are flush with the flat surface. Secure in place using two special CHROME NUTS (2) provided.
B) Position the MOUNTING GASKET (3) between the flat surface of the UNIVERSAL MOUNTING FLANGE (10) and
the appliance.
Line up the holes in the UNIVERSAL MOUNTING FLANGE with the STUDS (4) on the appliance mounting plate
and securely bolt the UNIVERSAL MOUNTING FLANGE to the plate.
C) Secure the two semi-flanges of the ADJUSTABLE COLLAR (9) to the AIR TUBE using the two long BOLTS (6).
Be sure that the ADJUSTABLE COLLAR (9) is properly positioned so the outside edge of the END CONE will be at
least 1/4 inch (6.5 mm) back from the inside wall of the refractory of the combustion chamber (see dimension B).
The measured length (A) is to include MOUNTING GASKET and FLANGE, if used.
D) The burner may now be attached to the heating unit by insetting the AIR TUBE through the BURNER ACCESS
HOLE (8) and into the appliance, making sure the BOLTS (1) line up with the two HOLES (5) in the ADJUSTABLE
COLLAR (9). Secure the burner in place using two NUTS (7).
A visual verification of the air tube insertion into the combustion chamber of the heating unit is suggested. Dimension B
should be at least 1/4” (see drawing).
NOTE:
A suggested method for creating mounting bolt holes in the mounting gasket: Hold the gasket against the appliance
mounting bolts using the mounting flange for proper positioning. Lightly tap the flange with a hammer to form the holes.
METHOD 2 – SEMI-FLANGE COLLAR
A) Follow item C from METHOD 1.
B) Align the air tube and attached adjustable collar so air tube is centered in the burner access hole of the boiler/furnace
unit.
Mark the center of the two holes in the ADJUSTABLE COLLAR on to the front plate of the heating unit. Then drill 1/
4 inch (6.5 mm) holes through the front plate of the unit, using marks as a guide.
C) Install two short BOLTS (1) through the front plate of the heating unit from the inside, and secure on the outside
using the two special CHROME NUTS (2).
D) Follow item D from METHOD 1.
METHOD 3 – 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, item A, C and D.
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.
WHEN THE COMBUSTION CHAMBER IS LINED WITH A REFRACTORY MATERIAL, IT IS IMPERA-
TIVE THAT THE END CONE NOT PROTRUDE INTO THE CHAMBER AREA, AS EXCESSIVE HEAT AT
BURNER SHUT DOWN WILL DAMAGE THE END CONE.

ELECTRICAL CONNECTIONS
It is advisable to leave the control box off the sub-base
while completing the electrical connection to the burner.
1) Wire access hole (Use BX electrical connector)
2) Earth ground conductor terminal (Green wire)
3) Hot conductor terminal (Black wire)
4) Neutral conductor terminal (White wire)
Strain relief clamp
Using the appropriate diagram below, make electrical connec-
tions to burner. All wiring must be done in accordance with existing electrical codes, both national and local.
When all electrical connections have been made, the control box may be put back in place on the sub-base.
APPLICATION FIELD WIRING
WARNING:
The hot (black) wire must be connected to the L terminal and
the neutral (white) wire must be connected to the N terminal
or the primary safety control will be damaged.
Do not connect wither wire to the terminal marked .
WARNING: DO NOT activate burner until proper oil line connections have been made, or failure of the pump shaft
seal may occur.

NOTE:
Terminal 4 is to be used to activate a remote safety lockout circuit only. A 120V AC source is supplied to Terminal 4 upon
lockout. The maximum allowable current draw for this circuit is 1 AMP.
IMPORTANT:
If a neutral or ground lead is attached to Terminal 4, the control box will be damaged should lockout occur.
NOZZLE PLACEMENT
A) Determine the proper firing rate for the boiler or furnace
units, considering the specific application, and then use the
Burner Setup Charts to select the proper nozzle and pump
pressure to obtain the required input from the burner.
B) Remove the NOZZLE ADAPTER (2) from the DRAWER
ASSEMBLY by loosening the SCREW (1).
C) Insert the proper NOZZLE into the NOZZLE ADAPTER and
tighten securely (Do not over tighten).
D) Replace adapter, with nozzle installed, into drawer
assembly and secure with screw (1).
