Optional Wall Thermostat or
Remote Control
Use only a 750 millivolt DC two-wire circuit thermostat
with this appliance. The thermostat should be placed
in the same room as the heater, typically 5 feet off the
floor. Avoid drafty areas or any area that may affect the
accuracy of the thermostat.
The thermostat should be connected to this appli
-
ance using a minimum of 16 gauge wire with a maxi-
mum length of 25 feet of wire.
Connect the two thermostat wire leads to the two
lower terminals on the terminal block located directly
above the ignitor button. Do not overtighten the con-
nections.
IT IS NOT NECESSARY TO DISCONNECT ANY
OTHER WIRES.
See Fig. 30.
For thermostatic operation, the On/Off/T-Stat switch
on the back of the stove must be in the T-stat position,
and the pilot light must be running, as it is the power
source for the thermostat.
At the thermostat, the two wires should be connect-
ed to the two connection screws on the thermostat base
plate per the manufacturer’s instructions.
Remote Control
When using a remote, the remote receiver should be
wired to the terminal block the same way the thermo-
stat would be. See the instructions above.
Follow the operating instructions included with the
Remote Control unit.
CAUTION:
LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING
THE CONTROLS. WIRING ERRORS CAN CAUSE IMPROPER OR
DANGEROUS OPERATION. ALWAYS VERIFY PROPER OPERATION
AFTER SERVICING THE APPLIANCE.

Flame Appearance / Air Shutter
Adjustment
This appliance is shipped from the factory equipped to
burn natural gas with the air shutter set half-open.
Be aware, however, that this initial setting may not provide
the optimal flame picture in your particular installation.
No single setting will be appropriate for all vent configu-
rations, fuel types, or installation environments. The air
shutter setting can also be adjusted to achieve the de
-
sired flame appearance. Flame appearance is a matter of
individual preference, however, most people enjoy a warm
yellowish flame.
Too much air -
the appliance will generate a flame that
is blue and transparent, or an “anemic” flame.
Too little air
- the appliance may generate very long
yellow flames resulting in soot. Sooting produces black
deposits on the logs, on the inside walls of the appliance,
and potentially, on the exterior termination cap. Sooting is
caused by incomplete combustion and lack of combustion
air entering the air shutter opening.
To adjust the air shutter: CAUTION! USE WORKGLOVES.
SURFACES MAY BE HOT!
1. Reach under the right side of the stove and loosen the
wingnut located closest to you. See fig. 29. Slide the
wingnut stem forward to open the air shutter and
increase air. Slide the shutter stem back to decrease the
air supply.
2. Tighten the wingnut to secure the shutter at the de-
sired setting.
3. Operate the burner for 30 minutes on the HIGH setting,
observing the flame continuously. If the flame appears
weak, slow, or sooty, adjust the air shutter to a more
open position as described above until the flame is as
desired. Make adjustments in small increments and
allow the burner to settle in before making further
adjustment
WARNING: AIR SHUTTER ADJUSTMENTS SHOULD ONLY
BE PERFORMED BY A QUALIFIED PROFESSIONAL SERVICE
TECHNICIAN.
