• Visually inspect all burner components and wiring.
• Verify that wiring is intact and leads are securely con-
nected.
Assemble burner (when required)
Welded-ange burners
1. Verify the bolt pattern on the appliance chamber matches
the ange pattern.
2. Verify the insertion depth (UTL) matches the depth of the
appliance opening (so the end of the air tube is ush with,
or slightly short of, the inside surface of the combustion
chamber).
