Inspecting Burners; Cleaning And Maintenance - Desa VV36EN-B Series Owner's Operation And Installation Manual

INSPECTING BURNERS

Check pilot flame pattern and burner flame patterns often.
PILOT ASSEMbLY
The pilot assembly is factory preset for the proper flame. Altera-
tions may have occurred during shipping and handling. The pilot
is located on the back right hand side of the burner.
The flame must envelope 1/4" of top of the ignitor/sensor and
grounding stem.
If your pilot assembly does not meet these requirements:
• Turn the adjustment screw marked PILOT clockwise to decrease
or counterclockwise to increase the flame to proper size (see
Figure 49, page 22). Do not remove the adjustment screw.
• see Troubleshooting, page 25

bURNER FLAME PATTERN
Burner flames will be steady; not lifting or floating. Flame patterns
will be different from unit to unit and will vary depending on instal-
lation type and weather conditions.
If the vent configuration is installed incorrectly, the flames will lift
or "ghost". This can be dangerous. Inspect the flames after instal-
lation to ensure proper installation and performance.
Figure 52 shows a typical flame pattern.
If burner flame pattern differs from that described:
• turn fireplace off (see To Turn Off Gas to Appliance, page 22)
• see Troubleshooting, page 25

Glass must be cleaned periodically. During start-up it is normal for
condensation to form on the inside of the glass causing lint, dust,
and other airborne particles to cling to the glass surface. During
initial start-up a slight film may form on the glass due to paint cur-
ing. The glass should be cleaned several times with a non-ammonia,
nonabrasive household cleaner and warm water after the first two
weeks of operation. Thereafter, clean the glass two or three times
during each heating season, depending on the usage and circum-
stances present. Refer to Removing/Replacing Glass Door on page
