If desired, the power supply and thermostat cable can
come into the wall stud space from a basement, crawl
space or an adjoining stud space.
Terminate flexible electrical conduit at the junction box
located on the underside of the header plate. Leave the
wires long enough to connect inside the junction box to
the convenience outlet.
CAUTION
Do not run wire behind flanges of header plate or
in any location where it might be damaged. Avoid
splicing thermostat wire unless the spliced wires are
properly cleaned, soldered and taped.

FIND THE STUDS AND CEILING JOISTS
(See CAUTION on page 6)
Find two studs at spot where furnace is to be placed.
Use a stud indicator or small finishing nails. Repeatedly
drive and remove a nail into the wall in the area of the
stud until you find it. Then find one side. Leave the nail
there. Drive another nail just on the other side of the same
stud.
Inside edge of the other stud should be about 14-1/2
inches from the one found. Drive finishing nail on inside
edge of this stud.
Using the nails as a guide, draw a line up both sides to
the ceiling to locate hole cut out for vent pipe and elec-
trical connections.
CUT CEILING OPENING
Mark off and cut 3-1/2 x 12 inch rectangular hole in ceil-
ing, centered between wall studs. The back edge of the
opening should be about 1/8 inch from the wall. See Fig.
16, page 14.
ELECTRICAL SUPPLY ROUGH-IN
The electrical supply openings must be made in the wall
or ceiling above furnace to match holes in furnace top.
Holes in furnace top are 1 inch from the left side of fur-
nace. See Fig. 13.
If desired, the power supply and thermostat cable can
come into the wall stud space from a basement, crawl
space or an adjoining stud space.
