OPERATING FIREPLACE
Continued
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.

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 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.
OPERATING
BLOWER
This blower has three settings: ON, OFF, and
AUTO. In the ON position, the blower will oper-
ate 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 distribute
heated air from the fireplace.

INSPECTING BURNERS
Check pilot flame pattern and burner flame pat-
terns often.
PILOT FLAME PATTERN
Figure 51 shows a correct pilot flame pattern.
Figure 52 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 52
• turn fireplace off (see To Turn Off Gas to Appli-
ance, page 23 for Thermostat-Controlled Mod-
els or page 25 for Remote-Ready Models)
• see Troubleshooting, page 30
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.
