All installations and services must be performed by qualified service personnel.

connector duct. Remove the bottom panel. Cut an opening in the distribution duct slightly larger than the connector duct. (refer to Figure 2 for location of this cut.) Cut the connector duct to length. Install the connector duct. Bend over each tab. Insure an airtight seal by using high temperature sealant or tape on the joint. Reinstall the bottom panel over the connector duct. Put the base top assembly in place (see Figure-3).

Slit the corners of connector duct down to the top of the base assembly. If metal projects more than 1-inch above the top of the base assembly, trim the flanges down to 1-inch. While the top of distribution duct is being pulled up with one hand, bend down each side of the connector duct tightly to the base assembly with the other hand. This assures a tight connection between the base assembly and the connector duct and that the distribution duct will be full size. Use high temperature tape and/or high temperature silicone caulking on all joints and seams to minimize air leakage. Secure the base assembly to the floor with two screws in the front flange.

2. Cottage Base Model: 01COT BASE (for CMA3 models only)

The 01COT BASE cottage base (Figure 1C) is required for a freestanding cottage base installation. The cottage base allows the two sides and rear to have an 8” x 12” register installed. IMPORTANT: All joints and seams of supply ducts must be sealed with a sealing method suitable to the application conditions and temperatures (I.E. High temperature silicone and/or aluminum tape). Refer to assembly and installation instructions included with cottage base for additional information.

The model CMC does not require a base for installation. The integrated coil cabinet serves as a base. The duct connection will be made to the bottom of the furnace. A sheet metal cover plate may be installed to protect any exposed combustible flooring.
