OPERATING FIREPLACE

Continued

Safety Features

When away from home for an extended period of timeorasachildsafetyfeaturetopreventaccidental ignitionofthefireplace,receiverON/OFF/REMOTE switch should be in the OFF position.

Auto Shutoff Feature

1. If the average room temperature exceeds 82° Fahrenheit (28° Centigrade), the hand-held remote control will perform a safety override and shut the fireplace off. This feature is not available in the MANU mode.

2. The receiver continuously receives signals from the hand-held remote to control the room temperature. If the hand-held remote is misplaced, obstructed or for any reason cannot transmit to the receiver, the receiver will shut off the fireplace after 8 minutes.

Key Pad Lock Feature

This feature allows the user to lock/unlock the keypad on the hand-held remote in the MANU or AUTO mode to prevent inadvertent operation (i.e. children operating the hand-held remote control, etc.). The keypad is locked in either on or off. Press the POWER and LOCK buttons together to turn the unit on or off.

Thermostat (OPTIONAL)

Make sure the heater switch is on REMOTE and set the temperature adjustment on wall thermostat to the desired setting. The thermo- stat has been electronically calibrated at the fac- tory 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 page 17 of this manual.

GWMS2 Wall Mounted

SWITCH (OPTIONAL)

Make sure the heater switch is on REMOTE. This wall switch works just like the conven- tional 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 being taken. See installation instructions on page 18 of this manual.

Inspecting Burners

Check pilot flame pattern and burner flame pat- terns often.

PILOT FLAME PATTERN

Figure 36 shows a correct pilot flame pattern. Figure 37 shows an incorrect pilot flame pattern. The incor- rect pilot flame is not touching the thermocouple. 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 37

•turn fireplace off (see To Turn Off Gas to Appli- ance, page 20 for Manual-Controlled Models or page 21 for Remote-Ready Models)

•see Troubleshooting, page 31

Note: The correct pilot flame on natural gas units will have a slight curve, but flame should be blue and have no yellow or orange color.

BURNER FLAME PATTERN

Figure 38, page 24, shows a correct burner flame pattern. Figure 39, page 24, shows an incorrect burner flame pattern. The incorrect burner flame pattern shows sporadic, irregular flame tipping. The flame should not be dark or have an orange/ reddish tinge.

Note: When using the fireplace the first time, the flame will be orange for approximately one hour until the log cures.
