Fuel supply below the level of the burner
When the fuel supply is more than eight feet below
the level of the burner, a two-pipe fuel supply system
is required. Depending on the fuel line diameter and
horizontal and vertical length, the installation may
also require a two-stage pump. Consult the fuel unit
manufacturer’s literature, included with the burner, for lift
and vacuum capability.
Fuel line installation
Continuous lengths of heavy wall copper tubing are
recommended. Always use fl are fi ttings. Never
use compression fi ttings.
Always install fi ttings in accessible locations.
Proper routing of fuel lines is required to prevent air
cavitation and vibration.

Wire burner
Burner packaged with appliance
Refer to appliance manufacturer’s wiring diagram for
electrical connections.
Burner installed at jobsite
Refer to Figures 7a and 7b, for typical burner wiring,
showing cad cell primary controls. Burner wiring may
vary, depending on primary control actually used.
Refer to the appliance manufacturer’s wiring diagram
prior to connecting the burner wiring. All wiring must be
in accordance with the latest revision of National Electric
Code NFPA 70 and all local codes and regulations.
In Canada, all wiring is to be in accordance with the
Canadian Electrical Code, Part 1.
Special wiring required with covered burners
The mounting plate is not a conduit connection point.
Pass the conduit and attached connector through the
opening in the mounting plate and attach it directly to the
burner-mounted 4x4 electrical box.
If attaching a burner cover to a previously installed
burner, attach the mounting plate and then slide the
conduit into the “J” shaped conduit slot.
Disconnect electrical power before installing or
servicing the burner.
Provide ground wiring to the burner, metal control
enclosures and accessories. (This may also be
required to aid proper control system operation.)
Perform all wiring in compliance with the National
Electrical Code ANSI/NFPA 70 (Canada CSA C22.1)
