Installation on Non-Combustible Flooring

See Figure 15

1. Cut floor opening keeping in mind clearances listed

on unit rating plate. Also keep in mind gas supply

connections, electrical supply, flue and air intake

connections and sufficient installation and servicing

clearances. See Table 1 for correct floor opening size.

2. Flange warm air plenum and lower the plenum into the

opening.

3. Set the unit over the plenum and seal the plenum to

the unit.

4. Ensure that the seal is adequate.

Installation on Combustible Flooring

See Figure 16

1. When unit is installed on a combustible floor, a

downflow combustible flooring base must be installed

between the furnace and the floor. The base must be

ordered separately. See Table 2 for opening size to

cut in floor.

2. After opening is cut, set the combustible flooring base

into opening.

3. Check fiberglass strips on the combustible flooring

base to make sure they are properly glued and

positioned.

4. Lower supply air plenum into the combustible flooring

base until plenum flanges seal against fiberglass

strips.

NOTE:

Be careful not to damage fiberglass strips.

Check for a tight seal.

5. Set the furnace over the plenum.
6. Ensure that the seal between the furnace and plenum

is adequate.

The furnace and combustible flooring base shall not be

installed directly on carpeting, tile, or other combustible

material other than wood flooring.
