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
49. The flame from the pilot burner must
extend beyond the thermopile.
If your pilot assembly does not meet these
requirements:
• turn fireplace off (see To Turn Off Gas to
Appliance, page 18)
• see Troubleshooting, pages 22 through 24
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 50 shows a typical flame pattern. If
burner flame pattern differs from that described:
• turn fireplace off (see To Turn Off Gas to
Appliance, page 18)
• see Troubleshooting, pages 22 through 24

OPERATING
OPTIONAL BLOWER
ACCESSORY
Locate the blower controls by opening
the lower louver panel on the fireplace.
Blower controls are located on the left
side of the switch bracket to the left just
inside the louver panel.
Both the GA3700 manual blower and the
DA3610T thermostatically-controlled
blower have 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.
Note for DA3610T Only: If you are
using DA3610T blower with optional
themostat (wall mount or remote con-
trol) for the fireplace, your fireplace and
blower will not turn on and off at the
same time. The fireplace may run for
several minutes before the blower turns
on. After the heater modulates to the pilot
position, the blower will continue to run.
The blower will shut off after the firebox
temperature decreases.
The blower helps distribute heated air
from the fireplace. Periodically check the
louvers of the firebox and remove any
dust, dirt, or other obstructions that will
hinder the flow of air.

OPTIONAL GWMT1
WALL MOUNTED
THERMOSTAT
Light the fireplace as instructed in Light-
ing Instructions on page 18. 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 fireplace off, adjust thermo-
stat 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.
