Notes:
The speed of this forced air duct system blower can be controlled by the
speed control that is installed with it. The speed control also has an off
position. This blower is energized only when the fireplace is up to tem-
perature. It will also shut off automatically when the fireplace cools down.
To maximize warm air distribution, this forced air duct system can be
used in conjunction with the Whole Home Comfort System described
in this manual.
