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 22 and 23.
·
Figure 22 shows a correct pilot flame pattern.
·
Figure 23 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 23.
Turn heater off (see To Turn off Gas to Appliance, page 17) See troubleshooting, page 21-23.
BURNER FLAME PATTERN
Figure 24 shows a correct burner flame pattern. Figure 25 shows an incorrect burner flame pattern. If pilot flame
pattern is incorrect then:
·
Turn heater off (see
“
To Turn off Gas to Appliance,
”
page 17).
·
See
Troubleshooting
, pages 21 through 23.
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.
