GWMT1 WALL MOUNTED THERMOSTAT (OPTIONAL)
Make sure the heater switch is on AUTO and set the temperature adjustment on wall ther- mostat 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 al- lowed to stabilize at room temperature for a minimum of 30 minutes for proper operation. See installation instructions on pages 20 and 21 of this manual.
GWMS2 WALL MOUNTED
SWITCH (OPTIONAL)
Make sure the heaterswitch is onAUTO.This wall switch works just like the conventional 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 fireplace being inadvertently turned on without the proper precautions be- ing taken. See installation instructions on page 21 of this manual.
OPERATING
BLOWER (OPTIONAL)
This blower has three settings: ON, OFF, and AUTO. In the ON position, the blower will op- erate constantly. In the OFF position, 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 distrib- ute heated air from the fireplace.

INSPECTING BURNERS
Check pilot flame pattern and burner flame pat- terns often.
PILOT FLAME PATTERN
Figure 43 shows a correct pilot flame pattern. Fig- ure 44 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermo- couple. This will cause the thermocouple to cool. When the thermocouple cools, the fireplace will shut down.
If pilot flame pattern is incorrect, as shown in Figure 44
•turn fireplace off (see To Turn Off Gas to Ap- pliance, page 23)
•see Troubleshooting, pages 28 through 31 Note: The pilot flame on natural gas units will have a slight curve, but flame should be blue and have no yellow or orange color.
