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.
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
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 19.

iNspECTiNG BURNERs

Check pilot flame pattern and burner flame pat-
terns often.
PILOT FLAME PATTERN
Figure 45 shows a correct pilot flame pattern.
Figure 46 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 46
• 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.

Figure 46 - Incorrect Pilot Flame Pattern
bURNER FLAME PATTERN
Figure 47 shows a correct burner flame pattern.
Figure 48 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.
If burner flame pattern is incorrect, as shown in
Figure 48
• turn fireplace off (see To Turn Off Gas to Appli-
ance, page 23)
• see Troubleshooting, page 30
