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 door panel. The valve is
attached to the underside of the burner
system assembly.
2. Disconnect from the valve the wires run-
ning from the ON/OFF switch.
3. Connect one terminal of the wire for the
wall thermostat to the THTP terminal on
the valve. Connect remaining wire termi-
nal to the TH terminal on the valve. Make
sure that the wire terminals are in the
positions on the unit as pictured in Figure
33, page 14. If wires are not connected as
shown the thermostat will not work.
4. Route the wire to a convenient location to
mount your thermostat (no outside wall).
IMPORTANT: The wire must not exceed
25 feet in length.
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 sunlight, fireplace,
or heat and air conditioning ducts.
5. Gently remove the cover of the thermostat
from the base. Grasp the sides of the
cover firmly and pull to separate from the
base.
6. Feed the electrical wires through the
rectangular slots (from the back) on each
side of the base (see Figure 34).
7. Connect one bare wire end to each termi-
nal ("W" and "R") of the thermostat base
(see Figure 35).
8. Install the base to the wall with screws
provided with thermostat.
9. Move the temperature adjustment back
20
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.
