Inspect the gas heat section of the unit. Verify the number of
burners match the number of heat exchanger openings and the
burner assembly is properly aligned. If the orifices were changed

1. Close the field-supplied manual gas shut off valve, located
external to the unit.
2. Connect a pre ssure gauge to the suppl y gas pressure tap,
located on the f ield-supplied manual gas shut off val ve (see
