Inspecting Burners - Procom FBD400RTCC-M-HC/MO Owner's Operation And Installation Manual

IMPORTANT: Owner's should check pilot flame pattern and burner flame pattern often.
Incorrect flame patterns indicate the need for cleaning (see Care and Maintenance,
page 25) or service.
WARNING: Only a qualified service person should service and
repair heater. This includes maintenance requiring replacement or
alteration of components.
Figure 26 shows a correct pilot flame pattern.
Figure 27 shows an incorrect pilot flame pat-
tern. The incorrect pilot flame is not touching
the thermocouple. This will cause the ther-
mocouple to cool, which shuts the heater off.
If pilot flame pattern is incorrect, as shown
in Figure 27
• turn heater off (see To Turn Off Gas to Ap-
pliance, page 19 or 21)
• see Troubleshooting pages 27 through 29.
WARNING: If yellow tipping
occurs, your heater could pro-
duce increased levels of carbon
monoxide. If the burner flame
pattern shows yellow tipping,
follow instructions at bottom of
this page.
Figure 28 shows a correct burner flame pattern. Figure 29 shows an incorrect burner flame
pattern. If burner flame pattern is incorrect then:
• turn heater off (see To Turn Off Gas to Appliance, page 19 or 21).
• see Troubleshooting pages 24 through 26.

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.
