THERMOSTAT

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

Light the fireplace as instructed in Light- ing Instructions on page 26. Set wall ther- mostat 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 tempera- ture for a minimum of 30 minutes for proper operation.

To turn the fireplace off, adjust thermo- stat to the lowest setting 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.

INSPECTING

BURNERS

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

60.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 your pilot assembly does not meet these requirements:

turn fireplace off (seeTo Turn Off Gas to Appliance, page 26)

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 installation type and weather conditions.

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

Figure 61 shows a typical flame pattern for HDV37N, HDV37P, HDV41N, and HDV41P models. Figure 62 shows a typical flame pattern for BHDV37N, BHDV37P, BHDV41N, and BHDV41P.

If burner flame pattern differs from that described:
