technician to clean and service the burner.
WARNING: Danger of bodily injury or death. Make
sure electric power and gas supply are off before
removing panels or doors.
Disconnect the gas line inside the cabinet.
Remove three screws from the front of the combustion chamber
bottom panel and drop the assembly down. Clean inside the
combustion chamber and the burner with a shop type vacuum
cleaner.
To remove burners remove screw from the end of the burner and
slide the burner out of its bracket (it may be necessary to slightly
spring the bracket).
Inspect the Burner Box gasket. Replace if damaged.
Replace burner assembly and control assembly by reversing the
above procedures.
Check the spark gap. It must be carefully adjusted to
specifications, as illustrated (Fig. 30), for the ignition device to
function properly.

The efficiency rating of these appliances is a product of a thermal efficiency rating system determined under continuous operating
conditions and was determined independently of any installed system.
**For elevations above 2,000 feet reduce ratings 4% for each 1,000 feet above sea level.
**Btu/hr. = British Thermal Units per hour.
