OPERATING OPTIONAL GWMT1

WALL MOUNTED THERMOSTAT

WARNING: Do not connect the thermostat to a power source. Electrical shock and/or a ﬁre hazard will occur.

Light the ﬁreplace as instructed in Lighting Instructions on page 23. Set wall thermostat to desired temperature.

This thermostat has been electronically calibrated at the factory and requires no adjustment or leveling.

Upon installation, the thermostat must be allowed to stabilize at room temperature for a minimum of 30 minutes for proper operation.

To turn the ﬁreplace off, adjust thermostat to the lowest set- ting and turn the gas control knob back to PILOT. The pilot will remain lit.

IMPORTANT: To turn the pilot off, turn the gas control knob on the heater to the OFF position.

OPERATING OPTIONAL

BLOWER ACCESSORY

Locate the blower controls by opening the lower louver panel on the ﬁreplace. Blower controls are located on the right side of the switch bracket to the left just inside the louver panel.

The BK manual blowerand the BKTthermostatically-controlled blower have an ON setting and an OFF setting. The blower will only run when the switch is in the ON position. In the OFF position, the blower will not operate.

Note for BKT Only: If you are using BKT blower with optional thermostat (wall mounted or remote control) for the ﬁreplace, your ﬁreplace and blower will not turn on and off at the same time.The ﬁreplace may run forseveral 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.

The blower helps distribute heated air from the ﬁreplace. Peri- odically check the louvers of the ﬁrebox and remove any dust, dirt or other obstructions that will hinder the ﬂow of air.

Check pilot ﬂame pattern and burner ﬂame patterns often.

PILOT ASSEMBLY

The pilot assembly is factory preset for the proper ﬂame height. Alterations may have occurred during shipping and handling. Call a qualiﬁed service person to readjust the pilot if necessary.

The height of the thermopile must be 3/8" to 1/2" above the pilot ﬂame as shown in Figure 48. The thermocouple must be at a height of about 1/8" above the pilot ﬂame. The ﬂame from the pilot burner must extend beyond both the thermocouple and thermopile.

If you pilot assembly does not meet these requirements:

•turn ﬁreplace off (see To Turn Off Gas to Appliance, page 24)

•see Troubleshooting, page 28

BURNER FLAME PATTERN

Burner ﬂames will be steady; not lifting or ﬂoating. Flame patterns will be different from unit to unit and will vary depending on instal- lation type and weather conditions.

If the vent conﬁguration is installed incorrectly, the ﬂames will lift or "ghost". This can be dangerous. Inspect the ﬂames after instal- lation to ensure proper installation and performance.

Figure 49 shows a typical ﬂame pattern.

If burner ﬂame pattern differs from that described:

•turn ﬁreplace off (see To Turn Off Gas to Appliance, page 24)

•see Troubleshooting, page 28
