Minimum clearances from the Plenum to any combustible materials must be maintained as listed on page 5. Failure to do so can
cause a fire or explosion resulting in property damage, personal injury or death.
Note:
Blower - Motor/Wheel assembly can be removed to make
Plenum section easier & lighter to install. Refer to Removal
and Replacement of Motor/Wheel Assembly, Page 18.
1. Connect the Plenum to the Vent Hood by aligning both grooves
on the bottom of Plenum with both grooves on the bottom of the
Vent Hood. The Plenum is designed to slide into the Vent
Hood, (See Diagram I).
2. Gently slide the Plenum into the Vent Hood until the slip joint
guides located on each side of the Plenum are in contact with
each other.
3. Slide the slip joint drivers from the bottom upward over the the slip joint guides as far as possible by hand. A hammer may be
used to tap the slip joint drivers to their final position. Start the slip joint drivers on the slip joint guides with the embossed end
facing down. Do not force slip joints past embossing.
INSTALLATION OF WALL SUPPORT BRACKET
1. To prevent damage to the SS1R, temporarily support the bottom of the plenum (prop on ladder) while assembling the wall
support bracket. Assemble the wall support bracket as shown, (See Diagram J).
2. Using the prepunched holes, adjust the wall support bracket so that a
slight pitch
is maintained for water drainage, (See
Diagram J).
3. Use the prepunched holes on the wall bracket as a template to mark holes to be drilled into the side wall for mounting screws.
4. a)
If installing the bracket into a wood wall, drill 2 pilot holes at each point established in step 3 with a 1/8" drill bit
approximately 1" deep and install the screws provided to secure the bracket to the wall.
b)
If installing the bracket into a masonry wall, drill 2 holes at each point established in step 3 with a 1/4" masonry drill bit
approximately 1" deep. Tap the masonry anchors into the holes drilled in step 4. Screw the wall bracket onto the wall.
5. Connect the other end of wall support bracket to the stud on the plenum using the supplied 1/4"-20 keps nut, (See Diagram J).
INSTALLATION OF VENT PIPE
Single wall vent pipe is not allowed in an unconditioned or unheated space. When Installing the SS1R vent system, a barometric
draft damper control must be used. Install the barometric draft damper as close as is practical to the SS1R with the center line of
the barometric damper not closer than 10 inches to the SS1R inlet. Always install the draft damper in a 6” section of pipe. The
general venting configurations are shown in diagram K. The SS1R vent system is designed to accept 6” single wall, type”L” or
type “A” vent pipe. When installing the vent system, it will be necessary to use the tapered reducers or increasers as shown.
Determine which inlet of the SS1R will allow for the least amount of elbows to the furnace. When using single wall pipe, a mini-
mum clearance of 18” must be maintained between the vent pipe and combustible materials and the vent pipe must be exposed to
view for its entire length. If this clearance cannot be maintained, type “L” or type “A” vent may be used according to its listing and
vent pipe manufacturer’s instructions.
A maximum of 10 linear feet of vent may be used to connect the SS1R to the furnace. No more than three 90
0
elbows may be
used (two 45
0
elbows will be considered equivalent to one 90
0
elbow).

IMPORTANT:
Adjust SS1R mounting
bracket for a slight downward
pitch towards exit terminal.
