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 running 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 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 46, page 22. If wires are not connected as shown the thermostat will not work.

4.Route the wire to a convenient location to mount your thermo- stat (no outside wall). IMPORTANT: The wire must not ex- ceed 25 feet in length. The thermostat should be mounted 54" above the floor in a location where there is good air circula- tion. Avoid heat sources such as lamps, direct sunlight, fire- place, 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 47).

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 terminal (“W” and “R”) of the thermostat base (see Figure 48).

8.Install the base to the wall with screws provided with thermostat.

9.Move the temperature adjustment back and forth to insure the bimetal is free from restrictions.

10.Replace the cover onto the base. (Upon installation, the ther- mostat must be allowed to stabilize at room temperature for a minimum of 30 minutes for proper operation.)

11.Set the temperature adjustment to the desired setting. This ther- mostat has been electronically calibrated at the factory. No ad- justment or leveling is necessary.
