INSPECTING BURNER
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure 18 shows a correct pilot flame pattern. Figure 19 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 pilot flame pattern is incorrect, as shown in Figure 19
• turn heater off (see To Turn Off Gas to Appliance, page 10)
• see Troubleshooting, pages 13 through 15

BURNER FLAME PATTERN
Figure 20 shows a correct burner flame pattern. Figure 21 shows an
incorrect burner flame pattern. The incorrect burner flame pattern
shows yellow tipping of the flame. It also shows the flame higher
than 1/2 the glass panel height.
WARNING: If yellow tipping occurs, your heater
could produce increased levels of carbon monoxide.
If burner flame pattern shows yellow tipping, see the
following instructions.
NOTICE: Do not mistake orange flames with yellow
tipping. Dust or other fine particles enter the heater
and burn causing brief patches of orange flame.
If burner flame pattern is incorrect, as shown in Figure 23
• turn heater off (see To Turn Off Gas to Appliance, page 10)
• see Troubleshooting, pages 13 through 15
