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
DA3610TA 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 DA3610TA Only:
If you are
using DA3610TA blower, 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.
OPERATING
OPTIONAL GWMS2
WALL MOUNTED
SWITCH
This wall switch works just like the con-
ventional light switch. Flip the switch up
for on and down for off.
Note:
Make sure that this switch is not in
a position to be mistaken for a light switch.
This may result in the heater being inad-
vertently turned on without the proper
precautions being taken. See installation
instructions on page 21 of this manual.
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.

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 incorrectly,
the flames will lift or “ghost”. This can be
dangerous. Inspect the flames after installation
to ensure proper installation and performance.
Figure 53 shows a typical flame pattern for
DVFE34 models.
If burner flame pattern differs from that
described:
• turn fireplace off (see To Turn Off Gas to
Appliance, page 24)
• see Troubleshooting, pages 27 through 29
