TO CLEAN OR CHANGE THE INJECTORS
Remove the two (2) gas lines connecting the gas control valve to the pilot and main
burner from both ends. Remove the main burner injector and the pilot injector. Clean the
injectors with a soft bristled brush and air. Reinstall both injectors and replace the two (2)
gas lines.
IMPORTANT NOTICE: Do not use any sharp or hard tool to clean the injectors as their
calibrated holes may become damaged.
Step 11 Slide the heads of the two (2) bolts at the bottom of the front cover into the
corresponding holes in the back cover (with the upper end of the front cover leaning
about an inch forward), push the front cover in and down until the bolts lock into place.
Slide the overhangs at the upper end of the front cover under the back cover and fix with
the two (2) screws. Tighten the two (2) bolts at the bottom of the front cover.
Before completing your periodic maintenance check, ensure that the heater area
is kept clear and free from combustible materials, gasoline and other
flammable vapors and liquids. Also, check to see that the flow of combustion and
ventilation air around the vent cap on the outside of the structure is not obstructed.
