MOUNTED
THERMOSTAT
(OPTIONAL)
Make sure the heater switch is on AUTO
and set the temperature adjustment on
wall thermostat to the desired setting.
The thermostat has been electronically
calibrated at the factory and requires no
adjustment or leveling.
Upon installation, the thermostat must
be allowed to stabilize at room tempera-
ture for a minimum of 30 minutes for
proper operation. See installation instruc-
tions on pages 16 and 17 of this manual.
GWMS2 WALL
MOUNTED SWITCH
(OPTIONAL)
Make sure the heater switch is on AUTO.
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 17 of this manual.
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.
Do not keep the hand-held remote
control unit too close to the heater.
The thermostat on the hand-held re-
mote control unit will heat up too
quickly and turn the heater off.

To turn the burner off, press the
AUTO/ON/OFF button until OFF
lights. The pilot will remain lit.
IMPORTANT:
To turn the pilot off,
manually turn the control knob on the
heater to the OFF position.
OPERATING
BLOWER
Auto/Off/On Switch
This blower has three settings: ON, OFF,
and AUTO. In the ON position, the blower
will operate constantly. In the OFF posi-
tion, the blower will not operate. In the
AUTO position, the blower will start when
the thermostat senses a sufficient increase
in firebox temperature.
Note:
Your fireplace and thermostat
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.
Note:
It is safe to operate fireplace with
blower turned off. However, the blower
helps distribute heated air from the
fireplace.
