3.Remove and save the four screws which hold the rotation plate on the partition panel. Note that one of the screws which hold the induced draft blower on the rotation plate needs to be removed.

4.Turn the rotation plate 90 degrees counterclockwise. The inner gasket must turn with the rotation plate.

5.Reinstall the rotation plate on the partition panel, using the four screws removed in step 3. Tighten screws to provide an airtight seal.

6.Make sure all wires are at least one inch from flue pipe. Relocate junction box to right side of cabinet if nec- essary. Refer to Section Vl for instructions.

WARNING

To prevent death or serious illness to building occupants due to flue products leaking into the building, proper installation of gaskets and screws is essential for providing a gas tight seal between the partition panel and the induced draft blower.

V. Masonry Chimneys

WARNING

Possibility of property damage, personal injury, or death - Damaging condensation can occur inside masonry chimneys when a single fan assisted Category I appliance (80% AFUE furnace) is vented without adequate dilution air. Do not connect an 80% furnace to a masonry chimney unless the furnace is common vented with a draft hood equipped appliance, or the chimney is lined with a metal liner or Type B metal vent. All installations using Masonry chimneys must be sized in accordance with the appropriate Venting Tables.

If an 80% furnace is common vented with a draft hood equipped appliance, the potential for condensation damage may still exist with extremely cold conditions, long vent connectors, exterior chimneys, or any combination of these conditions. The risk of condensation damage is best avoided by using the masonry chimney as a pathway for properly sized metal liner or Type B metal vent.
