INSPECTING
BURNER
Check pilot flame pattern and burner flame
pattern often.
PILOT FLAME PATTERN
Figure 18 shows a correct pilot flame pat-
tern. 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 appliance will shut
down.
If pilot flame pattern is incorrect, as shown
in Figure 19
• turn appliance off (see To Turn Off Gas
to Appliance, page 10)
• see Troubleshooting, pages 12 through 14

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
heat shield height.
If burner flame pattern is incorrect, as shown
in Figure 21
• turn appliance off (see To Turn Off Gas
to Appliance, page 10).
• see Troubleshooting, pages 12 through 14
WARNING: If yellow tipping
occurs, your CO2 generator could
produce increased levels of car-
bon monoxide. If burner flame
pattern shows yellow tipping, fol-
