Cleaning Pilot Orifice After use, cleaning of the pilot burner may be required for the proper flame. Also, cleaning of the pilot burner may be required due to spiders (spider webs). The pilot orifice can be cleaned with high pressure air or by placing under running water. Pilot orifice must be dry before replacement. Use a pipe cleaner to clean inside the pilot after the pilot orifice has been removed. Cleaning Combustion Chamber When the main burner and vent cap are removed, all internal areas of the combustion chamber are accessible for cleaning with a vacuum hose. TROUBLESHOOTING 1.

Relight the pilot and hold knob down longer and harder. Close lighter hole cover just after igniting. Check for a good pilot flame. c. Defective thermopile or defective magnet in safety section of valve. Replace. 3. Yellow pilot flame a. Obstruction at pilot orifice. b. Clean pilot orifice. 4. Pilot and main burner go out during normal operation. a. Check millivolts. b. Check for proper size of pilot flame. c. Check for defective or weak thermopile. d. Check input, reduce as needed. e.
