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, receiver ON/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.
GWMT1 WALL MOUNTED
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.
