INSTALLATION OF VENT PIPE
Single wall vent pipe is not allowed in unconditioned or unheated space. When Installing the SS1-R vent system, a barometric
draft damper control must be used. Install the barometric draft damper as close as is practical to the SS1-R with the center line of
the barometric damper not closer than 10 inches to the SS1-R inlet. Always install the draft damper in a 6” section of pipe. The
general venting configurations are shown in diagram K. The SS1-R 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 SS1-R 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 manufacturers instructions.
A maximum of 10 linear feet of vent may be used to connect the SS1-R 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).
The SS1-R vent system is shipped from the factory with the plug connected to the rear and the vent pipe inlet collar connected at
the bottom. If using the bottom inlet, read the section entitled “Vent Pipe Clamp Assembly”. If the installation requires the use of
the rear inlet, follow the steps in the section entitled “Vent Pipe Inlet Collar Conversation” to move the vent pipe inlet collar from the
bottom to the rear.

2. Remove the sensing tube from the Fan Proving Switch by loosening the plastic compression fitting.
3. Remove the vent pipe inlet collar from the bottom port by unfastening the 6 nuts that secure it to the plenum. Keep the nuts for
