Locating Wall Opening
The furnace is to be located on an outside wall. Locate wall
studs so that wall opening will be located between wall studs.
The furnace is 16 inches in width and normal 16 inches on
center studs will not allow the furnace to be recessed into the
wall unless a stud is repositioned. The wall opening required as
shown in Figure 5 is a diameter of 7-1/2 inches. Locate and cut
wall opening. If there is insulation above the wall opening (air
inlet tube) a barrier should be installed above the wall opening
(air inlet tube) to prevent insulation from coming in contact with
the air inlet tube.
A template is provided in furnace carton for positioning
furnace on the wall. Also, refer to Figure 5 for positioning the
furnace on wall and for locating gas line connection.
Installing Optional Side Outlets
Side outlet register, SOR-1 may be installed on one or both sides
of the furnace at the required clearances of 18 inches to adjacent
wall or combustible material as shown in Figure 4.

Locate and cut the 5-1/2" square opening in the cabinet
side using the template from the kit, exposing the inner
liner knock-out.
2.

side of the furnace at the required clearance of 4 inches to adja-
cent wall as shown in Figure 7.

side using the template from the kit, exposing the inner
liner knock-out.
2.
Remove the knock-out.
3.
Using the inner and outer boots as hole templates, mark
and drill (8) 1/8" diameter holes in the inner liner and
cabinet side.
4.
Using Figure 7 locate and cut a 6-3/4" square opening
through walls.
5.
Prepare wall opening for the vent-air intake system (see
Locating Wall Opening).
6.
With furnace in place, after checking alignment of side
outlet opening in wall and furnace, place the 9-3/8" x
9-3/8" side outlet wall plate over outer boot, pass the
outer boot through the wall and attach side outlet wall
