INSTALLING OPTIONAL
WALL MOUNTED
THERMOSTAT - GWMT1
WARNING: Installation must
be done by a qualified installer
familiar with low voltage wiring
procedures.
WARNING: Do not connect
this thermostat to any electrical
source! Electrical shock and/or
fire hazard will occur.
1. Open lower louver panel. The valve is
attached to the underside of the firebox
assembly.
2. Disconnect from the valve the wires
running from the ON/OFF switch.
3. Connect one terminal of 25 ft. wire for
the wall thermostat to the TPTH termi-
nal on the valve. Connect remaining
wire terminal to the TH terminal on the
valve. Make sure that the wire termi-
nals are in the positions on the unit as
pictured in Figure 41. If wires are not
connected as shown the thermostat will
not work.
4. Route the 25 ft. wire through openings
provided on the sides of the fireplace
to a convenient location to mount your
thermostat (no outside wall).
IMPORTANT: The wire may be short-
ened but must not be lengthened.
The thermostat should be mounted 54"
above the floor in a location where
there is good air circulation. Avoid
heat sources such as lamps, direct sun-
light, fireplace, or heat and air condi-
tioning ducts.
WARNING: Do not connect
this thermostat to a power
source. Electrical shock and/or
fire hazard will occur.

mostat from the base. Grasp the sides
of the cover firmly and pull to separate

rectangular slots (from the back) on
each side of the base (see Figure 42).
7. Connect one bare wire end to each ter-
minal (“W” and “R”) of the thermostat
base (see Figure 43).
8. Install the base to the wall with screws
provided with thermostat.
9. Move the temperature adjustment back
and forth to insure the bi-metal is free
from restrictions.
10. Replace the cover onto the base. (Upon
installation, the thermostat must be al-
lowed to stabilize at room temperature
for a minimum of 30 minutes for proper
operation.)
11. Set the temperature adjustment to the
desired setting.
This thermostat has been electronically
calibrated at the factory. No adjustment
or leveling is necessary.
