Inspect burner and components
•
Check the air tube length. Verify the insertion length of the tube UTL will
be long enough (see “Mount burner in appliance”).
•
Visually inspect all burner components and wiring.
•
Verify that wiring is intact and leads are securely connected.
•
Verify that all burner components are in good condition.
Do not install or operate the burner if any component is dam-
aged or if burner does not comply with other guidelines of this
manual and the appliance manual.
Mount burner in appliance
Welded-flange burners
1.
Verify the bolt pattern on the appliance chamber matches the flange
pattern.
2.
Verify the insertion depth (UTL), including spacers, matches the depth of
the appliance opening (so the end of the air tube is flush with, or slightly
short of, the inside surface of the combustion chamber).
3.
Place gasket onto boiler front plate.
4.
Slide the end of the air tube into the opening and secure the flange to
the boiler front plate.
Install the burner pedestal
(optional)
1.
Adjust the pedestal so that the height of the air tube matches the location
of the burner opening.
2.
The pedestal has approximately 3" of adjustment. If the burner opening
is too high for the pedestal to rest on the floor, then construct a base.
Two solid cement blocks, side by side, is recommended. Alternate the
direction as layers are put down.
3.
Place a spirit level on the air tube. Adjust the pedestal so the air tube
slopes down slightly toward the appliance. The slope should be about
2 degrees.
4.
Tighten the pedestal bolt securely.
2. Prepare site • assemble burner • mount burner
