When installing the double outlet system, the hot air outlets can be
installed in the same room as the fireplace, or one or both of the outlets
can be installed in adjacent or upper rooms. Installing the ducts at dif-
ferent elevations will tend to exhaust more heat out of the higher outlet
(
Figure 16
).

Fireplace Blower
The fireplace comes equipped with a heat activated blower. It is located
in the bottom of the fireplace, towards the back. It uses 120 V and must
be connected to the main electrical circuit by a qualified electrician. For
connection, use the electrical box supplied with the unit located on the
bottom right corner of the fireplace.
If you wish to adjust the blower speed, the variable speed control (VRUW)
provided must be installed in line with the wiring. Again, use a qualified
electrician for installation.
If the blower requires servicing,
1- Remove the doors and decorative facade.
2- Remove the screw located below the blower motor that holds it to the
back of fireplace.
3- Pull the blower out of the unit through the square hole located in the
front bottom right corner.
