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 Figure 34 and 35.
·
Figure 34 shows a correct pilot flame pattern.
·
Figure 35 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 Figure 35. Turn heater off (see "To Turn Off Gas to Appliance",
page 21). See Troubleshooting, page 26-28.

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.
