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.
Note for CDA3620T Only:
If you are
using CDA3620T 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.
HAND-HELD REMOTE
OPERATION
The thermostat control setting on the
remote control unit can be set to any
comfort level between HI and LO. The
burners will turn on and off automati-
cally to maintain the comfort level you
select. The ideal comfort setting will vary
by household depending upon the amount
of space to be heated, the output of the
central heating system, etc.
1.
After lighting, let pilot flame burn for
about one minute. Turn gas control
knob on the control valve to ON po-
sition. Turn variable control knob
anywhere between HI and LO. Slide
the selector switch to the REMOTE
position.
Note:
The burner(s) may light if hand-
held remote ON button was on when
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 selec-
tor switch in the REMOTE position
when the pilot is not lit. This will drain
the battery.
IMPORTANT:
Be sure to press the
ON/OFF buttons on the hand-held
remote control unit for up to 3 sec-
onds to assure proper operation.
2.
Select the MAN (manual) or AUTO
button on the hand-held remote con-
trol unit (see Figure 52).
• In manual mode, turn burners on or
off by pressing the ON/OFF buttons
on the hand-held remote control unit.
• In auto mode, the room tempera-
ture is controlled by the thermo-
stat in the hand-held remote con-
trol unit. To increase the room tem-
perature, press the top arrow of the
TEMP button. To lower the room

temperature, press the bottom ar-
row of the TEMP button. At higher
settings the heater will run more.
IMPORTANT:
This remote control
has been specially engineered to take
an air temperature sample every 5.5
minutes in the AUTO mode. It will not
respond immediately to the tempera-
ture setting being turned up or down.
IMPORTANT:
The hand-held remote
control unit must be near the heater
but not extremely close to it. The
thermostat on the hand-held remote
control unit will heat up too quickly
and turn the heater off.
3.
Use the STATUS button on the hand-
held remote control unit to see the
operation mode being used and the
temperature setting selected. A red
light will come on beside the opera-
tion mode being used.
4.
To turn the burners off when operat-
ing in the manual mode, press the OFF
button. If operating in the auto mode,
press the MAN button, then press the
OFF button. The pilot will remain lit.
IMPORTANT:
To turn the pilot off,
manually turn the gas control knob
on the heater to the OFF position or
set selector switch to OFF position.
