Operating Fireplace

operating optional

blower accessory

Locate the blower controls by opening the lower louver panel on the fireplace. Blower controls are located on the left 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.

Inspecting Burners

Check pilot flame pattern and burner flame patterns often.

pilot assembly

The pilot assembly is factory preset for the proper flame. Altera- tions may have occurred during shipping and handling. The pilot is located on the back right hand side of the burner.

The flame must envelope 1/4" of top of the ignitor/sensor and grounding stem.

If your pilot assembly does not meet these requirements:

Turn the adjustment screw marked PILOT clockwise to decrease or counterclockwise to increase the flame to proper size (see Figure 49, page 23). Do not remove the adjustment screw.

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 52 shows a typical flame pattern.

If burner flame pattern differs from that described:

turn fireplace off (see To Turn Off Gas to Appliance, page 23)
