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 18. Set wall ther- mostat to desired temperature.
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.
INSPECTING
BURNERS
Check pilot flame pattern and burner flame patterns often.
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 50 shows a typical flame pattern. If burnerflamepatterndiffersfromthatdescribed:
•turn fireplace off (see To Turn Off Gas to Appliance, page 18)
•see Troubleshooting, pages 22 through 24
This thermostat has been electronically calibrated at the factory and requires no adjustment or leveling.
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 GA3700 manual blower and the DA3610T
Note for DA3610T Only: If you are using DA3610T blower with optional themostat (wall mount or remote con- trol) for the fireplace, 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.
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
49. The flame from the pilot burner must Figure 50 - Typical Flame Pattern extend beyond the thermopile.
If your pilot assembly does not meet these requirements:
•turn fireplace off (see To Turn Off Gas to Appliance, page 18)
•see Troubleshooting, pages 22 through 24
