ORIFICE
The orifice is cleaned by using an alcohol based solvent and allowing to air dry.
If there is a lack of cooling on gas operation, verify the orifice is the proper size per the chart below:
S1521 #43 RM2607 #53 RM3662 #58
S1531 #43 RM2611 #53 RM3663 #58
S1621 #58 RM2807 #58 RM3862 #58
S1631 #58 RM2811 #58 RM3863 #58
S1821 #58 RM3607 #53 RM4872 #58
S1831 #58 RM3807 #58 RM4873 #58
THERMOCOUPLE
The thermocouple should produce 25 to 35 millivolts when connected to the lower circuit board. Any
reading below 18 millivolts could cause erratic gas operation.
BURNER
The slots in the burner should be directly below the flue tube. The burner should be cleaned periodically,
at least once a year. Soak the burner in an alcohol based solvent and allow to air dry.
FLUE BAFFLE
It should be cleaned periodically, at least once a year.
The proper position of the baffle above the burner
should be as follows:
S1521 2-1/4" RM2607 1-5/8"
S1531 2-1/4" RM2611 1-5/8"
S1621 1-5/8" RM2807 1-3/4"
S1631 1-5/8" RM2811 1-3/4"
S1821 1-5/8" RM3607 1-5/8"
S1831 1-5/8" RM3807 1-3/4"
RM3662 1-7/8"
RM3663 1-7/8"
RM3862 1-7/8"
