INSPECTING BURNERS
Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
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 he thermocouple to cool. When the thermocouple
cools, the heater will shut down.
If pilot flame pattern is incorrect, as shown in Figure 35:
Turn heater off (see
“
To Turn Off Gas To Appliance”).

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.
