Inspecting Burners - EmberGlow VFS25NL Owner's Operation

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 19 or service.
WARNING: Only a qualified service person should service and
repair heater. This includes maintenance requiring replacement or
alteration of components.
Figure 19 shows a correct pilot flame pattern.
Figure 20 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 20
• turn heater off (see To Turn Off Gas to Ap-
pliance, page 17)
• see Troubleshooting pages 21 through 23.
WARNING: If yellow tipping
occurs, the pilot should be
cleaned.
Notice: Do not mistake orange flames with
yellow tipping. Dirt or other fine particles enter
the heater and burn causing brief patches of
orange flame.
Figure 21 shows a correct burner flame pattern. Figure 22 shows an incorrect burner flame
pattern. If burner flame pattern is incorrect as shown in Figure 22:
• turn heater off (see To Turn Off Gas to Appliance, page 17).
• see Troubleshooting pages 21 through 23.

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.
