with (6) #8 x 3/8" (9mm) screws provided.
8. Align clearance holes on 6" x 10" (152mm x 254mm) duct with
screw holes on inner casing back and mark duct to be 2 1/4"
(57mm) shorter than 8" x 12" (203mm x 305mm) boot. Remove
duct and cut to proper length.
9. Attach 6" x 10" (152mm x 254mm) duct to inner casing back with
(4) #8 x 3/8" (9mm)screws removed in Step 3, 2 on top and 2
on bottom.
10. Insert rear register into 8" x 12" (203mm x 305mm) boot. Attach
rear register to wall with (2) #10 x 1"(25mm) screws provided.
11. Installation of ROK-1 is completed.
Locating Furnace On Wall
The furnace is to be located on a wall. The furnace is 14 1/8" (35.9cm)
in width and can be recessed into the wall with typical stud spacing.
A template is provided in furnace carton for locating gas line
connection. Also, refer to Figure 7 for positioning the furnace on
wall and for locating gas line connection.
Locating Gas Supply
The gas line can enter the furnace either through the floor or 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. See Figure 7.

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 assembly
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.
Installation of Three-prong (Grounding) Plug Assembly
1. Disconnect nylon cap on 3' (914mm) plug assembly from nylon
plug on wiring harness. Remove 3' (914mm) 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' (914mm) plug assembly into the 7/8"
(22mm) hole in the side panel.
4. Connect nylon cap on 3' (914mm) plug assembly to nylon plug
on the wiring harness.
5. Place 7/8" (22mm) strain relief bushing around the cord of the 3'
(914mm) 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

Attaching Furnace to Wall
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.
Gas Supply
Check all local codes for requirements, especially for the size and
type of gas supply line required. On Natural gas lines less than 75'
(22.9m) long, use 1/2" (13mm) pipe; on longer runs, use 3/4" (19mm)
iron pipe or equal. On LP gas lines please consult LP gas supplier.
Installing a New Main Gas Cock
Each appliance should have its own manual gas cock.
A manual main gas cock should be located in the vicinity of the unit.
Where none exists, or where its size or location is not adequate,
contact your local authorized installer for installation or relocation.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liquefied petroleum gases. The gas lines must be
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.
Never use an exposed flame to check for leaks. Appliance must
be disconnected from piping at inlet of control valve and pipe
capped or plugged for pressure test. Never pressure test with
appliance connected; control valve will sustain damage!
A gas valve and ground joint union should be installed in the gas
line upstream of the gas control to aid in servicing. It is required by
the National Fuel Gas Code that a drip line be installed near the gas
inlet. This should consist of a vertical length of pipe tee connected
into the gas line that is capped on the bottom in which condensation
and foreign particles may collect.

Method of Installing a Tee Fitting Sediment Trap
The use of the following gas connectors is recommended:
— ANS Z21.24 Appliance Connectors of Corrugated Metal Tubing
and Fittings
— ANS Z21.45 Assembled Flexible Appliance Connectors of Other
Than All-Metal Construction
The above connectors may be used if acceptable by the authority
having jurisdiction.
Pressure Testing of the Gas Supply System
1. To check the inlet pressure to the gas valve, a 1/8" (3mm) N.P.T.
plugged tapping, accessible for test gauge connection, must be
placed immediately upstream of the gas supply connection to
the appliance.
2. The appliance and its individual shutoff valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of
1/2 psig (3.5 kPa).
3. The appliance must be isolated from the gas supply piping system
by closing its individual manual shutoff valve during any pressure
testing of the gas supply piping system at test pressures equal
to or less than 1/2 psig (3.5 kPa).
