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 GA3750 manual blower and the
CDA3620T 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.
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.
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
53. The thermocouple must be at a height of
about 1/8" above the pilot flame. The flame
from the pilot burner must extend beyond
both the thermocouple and thermopile.
If your pilot assembly does not meet these
requirements:
• turn fireplace off (see To Turn Off Gas to
Appliance, page 25)
• see Troubleshooting, pages 28 through 30

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 54 shows a typical flame pattern for
CDV37N, CDV37P, CDV41N, and
CDV41P models.
If burner flame pattern differs from that
described:
• turn fireplace off (see To Turn Off Gas to
Appliance, page 25)
• see Troubleshooting, pages 28 through 30

HAND-HELD REMOTE
OPERATION
1.
After lighting, let pilot flame burn for
about one minute. Turn control knob
on the control valve to ON position.
Turn flame adjustment knob any-
where between HI and LO. Turn the
knob to the REMOTE setting.
Note:
The burners may light if hand-held
remote selector switch was last
turned off. You can now turn the
burners on and off with the hand-
held remote control unit.
IMPORTANT:
Do not leave the re-
mote selector switch in the REMOTE
position when the pilot is not lit. This
will drain the battery.
2.
Press the ON/OFF button to turn the
burners on and off. When turning
burners off, the pilot will remain lit.
IMPORTANT:
To turn the pilot off,
manually turn the control knob on the
heater to the OFF position.
NOTICE: You must light the pilot
before using the hand-held re-
mote control unit. See
Lighting
Instructions, page 25.
