Designer Series Direct Vent Gas Fireplace
The ames from the burner should be visually checked
as soon as the heater is installed and periodically
during normal operation. In normal operation, at full
rate, and after operating for about 15 to 30 minutes,
the ame should be yellow and slightly taller than the
rear log. Figure 67
If the ame is blue and only in the center, turn off unit
and let cool. After unit is cool, remove logs and check to
make sure the back holes in the burner are not covered
with rock wool. If the back holes are clear, add more
rock wool to the center of the burner. Replace logs.
The type of installation, vent system
conguration, and wind effects may cause the ame
patterns to vary.
Keep the control compartment, logs, and burner areas
surrounding the logs clean by vacuuming or brushing at
least twice a year. Make sure the burner porting, pilot air
opening and burner air opening are free of obstructions
at all times.
The ames from the pilot should be visually checked as
soon as the heater is installed and periodically during
normal operation.
Figure 66. The
pilot ame has four distinct ames, one engulng the
thermopile, one engulng the sensor, and the other two
reaching to the main burners.
Inspect area around the injector. Remove any lint or foreign
material with a brush or vacuum.
