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 fire- box 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 control valve as pictured in Figure 40. If wires are not connected as shown, the ther- mostat 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 sunlight, fireplace, or heat and air conditioning ducts.

5.Gently remove the cover of the ther- mostat 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 41).

WARNING: Do not connect this thermostat to a power source. Electrical shock and/or fire hazard will occur.

7.Connect one bare wire end to each ter- minal (“W” and “R”) of the thermostat base (see Figure 42).

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.
