INSPECTING BURNERS
Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
1. Turn control knob to pilot position
2. Inspect pilot flame and refer to Fig. 20 and 21.
• Fig. 20 shows a correct pilot flame pattern.
• Fig. 21 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will cause the
thermocouple to cool. When the thermocouple cools, the heater will shut down.
• If the pilot flame is incorrect, as shown in Fig. 21, turn heater off (see “To Turn Off Gas to Appliance,” page 19). See
Troubleshooting, page 22 - 23.

BURNER FLAME PATTERN
Fig. 22 shows a correct burner flame pattern. Fig. 23 shows an incorrect burner flame pattern.
• If burner flame is incorrect, as shown in Fig. 23, turn heater off (see “To Turn Off Gas to Appliance”, page 19).
• see Troubleshooting, pages 22 through 23.
BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes in the fitting at the entrance to the burner. These holes may become blocked with
dust or lint. Periodically inspect these holes for any blockage and clean as necessary. Blocked air holes will create soot.
