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.
