Central forced air kit (Not EPA "Environmental Protection Agency" approved)
The knock-outs provided on the back and on the sides of the BIS ULTRA allow the connection of
insulated flexible pipe which enables you to heat adjacent rooms up to 50 feet from the fireplace.
The ducting system must be installed as described below :
1.
Fix the adaptor at the back and/or the side of the fireplace by twist-locking the adaptor to the
fireplace. You can use more than one outlet on the fireplace (figure 19).
2.
Attach the 5" flexible pipe, using the collars provided. Important : Make sure that the plastic
wrapping around the flexible pipe will not be in contact with the fireplace.
3.
Route the flexible pipe to the chosen location. The ducting system can be installed either in an upper room or in a
lower room.
4.
Attach the flexible pipe to the fan, using the collars (figure 20).
5.
Fix the decorative grill fan adaptor to the fan.
6.
Attach a standard 3" x 10" grill to the adaptor.
7.
Install the
blower thermostat
in that part of the house to be heated by the hot air duct. Do not install the
blower
thermostat
in the room where the fireplace is located. A
cooling thermostat
can be installed in the same room as
the unit. This thermostat will turn on the blower when the room where the fireplace is located becomes too hot.
This option requires electricity. Make sure that the connections to the fan have been made according to the local codes
and comply with their requirements.
It is possible to connect a flexible pipe to a central heating system. Make sure the pipe will be
connected to the warm air supply duct, not to the return air duct (figure 21).
