Locating Gas Supply
The gas line can enter the furnace either through the floor or
outside wall. The gas line opening should be made at this time.
Location of the opening will be determined by the position of floor
joists and the valve and union used for servicing.
Locating Electric Supply
A 7/8" (22mm) diameter knockout is provided at the bottom of the
left and right side panels. A three-prong (grounding) plug assem-
bly is located within the control compartment (bottom) of the
furnace. Please remove 7/8" (22mm) knockout from appropriate
side panel when routing plug assembly to an electrical outlet. Unit
can be hard wired when recessed. Remove the 3 prong plug
assembly and terminate inside the unit junction box.

Installation of Three-prong (Grounding) Plug Assembly
1. Disconnect nylon cap on 3' (92cm) plug assembly from nylon
plug on wiring harness. Remove 3' (92cm) plug assembly from
control compartment (bottom) of the furnace.
2. Remove 7/8" (22mm) knockout from appropriate side panel.
3. Insert nylon cap on 3' plug assembly into the 7/8" (22mm) hole
in the side panel.
4. Connect nylon cap on 3' (92cm) plug assembly to nylon plug on
the wiring harness.
5. Place 7/8" (22mm) strain relief bushing around the cord of the
3' (92cm) plug assembly. Insert 7/8" (22mm) strain relief
bushing into the 7/8" (22mm) hole in the side panel.
Attention! The 7/8" (22mm) strain relief bushing is located within
the same yellow envelope as the Installation Instructions and
Owner's Manual.
Attaching Furnace to Wall
Refer to Figure 2 for the location of the 7 1/2" (191mm) diameter
wall opening for the furnace. After the wall opening has been
located and cut, position flue outlet on furnace in center of wall
opening. When attaching furnace to the wall remove that portion
of baseboard and molding on the wall which is behind the furnace.
Attach furnace to wall, at the outer casing top, with (2) toggle bolts
provided and to floor, at the outer casing bottom, with (2) #10 x 1
1/2" (38mm) screws provided.
Cutting Vent Tubes
This is the most important part of the installation. With the furnace
installed on wall the 6" (152mm) diameter air inlet tube and the 4"
(102mm) diameter flue outlet tube are to be marked and cut using
the following procedure.
1. Attach 6" (152mm) diameter air inlet tube onto the collar of air
drop assembly. Be sure 6" (152mm) diameter air inlet tube is
placed as far as possible onto the collar of the air drop assembly.
6. Position and attach inner boot to inner shield with (4) #8 x 1/4"
(6mm) provided screws.
7. Place the register over the 6 3/4" (171mm) square opening
with the louvers positioned for the desired discharge direction
and mark the mounting holes using the register as a template.
8. Drill (2) 1/8" (3mm) diameter holes in the wall and attach the
register with (2) #10 x 1 1/2" (38mm) provided screws.
9. Installation of SOK-1 is completed.
