BLOWER ACCESSORY INFORMATION

Code.
U.S. Installations, follow local codes and the National Electrical

BLOWER ACCESSORY
Operation
The fireplace insert is equipped with a factory installed blower accessory
that includes a fan control switch, plus a rheostat (speed control).
The speed control knob is located behind the lower louver at the right
side of the insert.
From a cold start, the temperature activated fan control switch will
normally take 5-10 minutes to heat up and energize the blower.
Once the blower is energized, adjust the blower speed control as desired,
then replace the lower louver.
When the insert is shut off, it may take 30-40 minutes for the heated unit
to dissipate (cool down) enough for the blower to shut off automatically.
Note: The blower shut off times will vary on blower speed and BTU
input level setting control by adjustment of the HI/LO knob located on
the gas valve.
Blower removal instructions
Servicing or removal of the blower system must be performed by a
qualified service person.
If the blower assembly (Item 45, page 24) must be replaced, the following
steps are recommended for removal:
1. Turn off gas and disconnect the electrical supply.
2. Remove the glass door assembly.
3. Remove the log set.
4. Remove the front surround panel assembly by lifting upward and

the insert, and at the same time, sliding the vent plate rearward until

by locating the (6) screws on the lower back of the insert that retains
the blower base plate.
