3. Place the adapter with the attached starter ring over the flapper plate and secure them to the top of the fireplace using the four screws that held

the cover plate.

4. Fasten the remaining components of the duct: flex line, duct adapter, wall stack and fan box using at least three sheet metal screws and aluminum

duct tape at each joint.

Wiring of the Forced Air System:

Disconnect the electrical supply to the fireplace at the electrical panel prior to wiring the forced air system fan. All wiring should be done by a quali-

fied electrician.

1. After installing the fan box and ducting from the fireplace to the fan box, the wiring of the fan box should be undertaken. Included in the ducting kit

are two electrical switch boxes. One is for installation in new construction and the other is to be used in a remodel. Select the switch box needed

and fasten it to the wall framing in the room in which the fan box is located.
