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 24. 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 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 left side of the switch bracket to the left just inside the louver panel.

Both the GA3750 manual blower and the CDA3620T thermostatically 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 CDA3620T Only: If you are using CDA3620T blower, your fireplace and 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.

The blower helps distribute heated air from the fireplace. Periodically 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 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

56.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 (seeTo Turn Off Gas to Appliance, page 24)

•seeTroubleshooting, pages 28 through 30

Thermopile

3/8" to 1/2"

Pilot Burner

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 57 shows a typical flame pattern for CHDV34(N/P)(A) models.

If burner flame pattern differs from that described:

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

•seeTroubleshooting, pages 28 through 30
