OPERATING FIREPLACE
Continued
Note: Do not hold the hand-held remote for
a long time. Body temperature will affect its
operation in the AUTO mode.
Safety Features
When away from home for an extended period
of time or as a child safety feature to prevent
accidental ignition of the fireplace, the receiver
ON/OFF/REMOTE switch should be in the
OFF position.
Auto Shutoff Feature
1. If the average room temperature exceeds 82
degrees Fahrenheit (28 degrees 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.
OPTIONAL GWMT1 WALL
MOUNTED THERMOSTAT
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 al-
lowed to stabilize at room temperature for a
minimum of 30 minutes for proper operation.
See installation instructions on page 19.
INSPECTING BURNERS
Check pilot flame pattern and burner flame pat-
terns often.
PILOT FLAME PATTERN
Figure 43 shows a correct pilot flame pattern.
Figure 44 shows an incorrect pilot flame pattern.
The incorrect pilot flame is not touching the ther-
mocouple. 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 Appli-
ance, page 23)
• see Troubleshooting, page 28
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.

OPTIONAL GWMS2 WALL
MOUNTED SWITCH
Make sure the heater switch is on AUTO. 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 posi-
tion 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 19.
