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.

3.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.

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.

OPERATING BLOWER

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.

INSPECTING

BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT FLAME PATTERN

Figure 41 shows a correct pilot flame pat- tern. Figure 42 shows an incorrect pilot flame pattern. The incorrect pilot flame is not properly heating the thermocouple. When the thermocouple cools, the heater will shut down.

If pilot flame pattern is incorrect, as shown in Figure 42.

•turn heater off (see To Turn Off Gas to Appliance, page 19)

•see Troubleshooting, pages 22 through 24
