Safety Features
When away from home for an extended period of time or as a child
safety feature to prevent accidental ignition of the fireplace, the
receiver ON/OFF/REMOTE switch should be in the OFF position.
Auto Shutoff Feature
1. If the average room temperature exceeds 82 degrees Fahr-
enheit (28 degrees Centigrade), the hand-held remote con-
trol will perform a safety override and shut the fireplace
off. This feature is not available in the MANU mode.
2. The receiver continuously receives signals from the hand-
held remote to control the room temperature. If the hand-
held remote is misplaced, obstructed, or for any reason can-
not transmit to the receiver, the receiver will shut off the
fireplace after 8 minutes.
Key Pad Lock Feature
This feature allows the user to lock/unlock the keypad on the
hand-held remote in the MANU or AUTO mode to prevent
inadvertent operation (i.e. children operating the hand-held re-
mote control, etc.). The keypad is locked in either on or off. Press
the POWER and LOCK buttons together to turn the unit on or off.
OPERATING OPTIONAL
BLOWER ACCESSORY
Blower controls are located on left side of rear cover (when
standing in front of stove).
The CDA3620TB thermostatically-controlled blower has 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.
If you are using CDA3620TB blower with optional thermostat
(wall mount or remote control) for the burner system, your
burner system and blower will not turn on and off at the same
time. The burner system may run for several minutes before the
blower turns on. After the burner system modulates to the pilot
position, the blower will continue to run. The blower will shut off
after the burner system temperature decreases.
The blower helps distribute heated air from the burner system.
Periodically check the air passageways of the burner system
and remove any dust, dirt, or other obstructions that will hinder
the flow of air.
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 burner system as instructed in Lighting Instructions on
page 26. 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 burner system off, adjust thermostat 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 burner system 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 63. 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 burner system off (see To Turn Off Gas to Appliance, page 26)
• see Troubleshooting, page 30

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 incorrectly, the flames will lift
or "ghost". This can be dangerous. Inspect the flames after instal-
lation to ensure proper installation and performance.
Figure 64 shows a typical flame pattern. If burner flame pattern differs
from that described:
• turn burner system off (see To Turn Off Gas to Appliance, page 26)
• see Troubleshooting, page 30
