INSPECTING BURNERS
Check pilot ame pattern and burner ame patterns often.
PILOT FLAME PATTERN
Figure 19 shows a correct pilot ame pattern. Figure 20 shows an incorrect pilot ame pattern. The incorrect pilot
ame is not touching the thermocouple. This will cause he thermocouple to cool. When the thermocouple cools,
the heater will shut down.
If pilot ame pattern is incorrect, as shown in Figure 20:
• Turn heater off (see “To Turn Off Gas To Appliance”).
• See Troubleshooting, page 20.

BURNER FLAME PATTERN
Figure 23 shows a correct burner ame pattern. Figure 24 shows an incorrect burner ame pattern. If burner
ame is incorrect:
• Turn heater off.
• See Troubleshooting, page 20.
BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes in the tting 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.
