INSPECTING
BURNERS
Check pilot flame pattern and burner flame
patterns often.
PILOT ASSEMBLY
The pilot assembly is factory preset for the
proper flame height. Alterations may have
occurred during shipping and handling. Call
a qualified service person to readjust the
pilot if necessary.
The height of the thermopile must be 3/8" to
1/2" above the pilot flame as shown in
Figure 54. The flame from the pilot burner
must extend beyond the thermopile.
If your pilot assembly does not meet these
requirements:
• turn burner system off (see To Turn Off
Gas to Appliance, page 19)
• see Troubleshooting, pages 23 through 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
installation type and weather conditions.
If the vent configuration is installed incor-
rectly, the flames will lift or “ghost”. This
can be dangerous. Inspect the flames after
installation to ensure proper installation
and performance.
Figure 55 shows a typical flame pattern. If
burner flame pattern differs from that described:
• turn burner system off (see To Turn Off
Gas to Appliance, page 19)
• see Troubleshooting, pages 23 through 25

OPERATING
OPTIONAL BLOWER
ACCESSORY
Blower controls are located on the left
side of the rear cover of stove (from front
of stove).
The DA3610TA thermostatically-con-
trolled blower has an ON setting and an
OFF setting. The blower will only run
when the switch is in the ON position. In
the OFF position, the blower will not
operate.
If you are using DA3610TA blower with
optional thermostat (wall mount or re-
mote control), your burner system and
blower will not turn on and off at the
same time. The burner system may run
for several minutes before the blower
turns on. After the heater modulates to
the pilot position, the blower will con-
tinue to run. The blower will shut off after
the burner system firebox temperature
decreases.
The blower helps distribute heated air
from the burner system. Periodically
check the top grates of the stove and
remove any dust, dirt, or other obstruc-
tions that will hinder the flow of air.
OPERATING
OPTIONAL GWMT1
WALL MOUNTED
THERMOSTAT
Light the fireplace as instructed in Light-
ing Instructions on page 19. Set wall ther-
mostat to desired temperature.
This thermostat has been electronically
calibrated at the factory and requires no
adjustment or leveling.
WARNING: Do not connect
the thermostat to a power source.
Electrical shock and/or a fire haz-
ard will occur.
Upon installation, the thermostat must
be allowed to stabilize at room tempera-
ture for a minimum of 30 minutes for
proper operation.
To turn the burner system off, adjust
thermostat to the lowest setting and turn
the gas control knob back to PILOT. The
pilot will remain lit.
IMPORTANT:
To turn the pilot off,
turn the control knob on the heater to
the OFF position.
