Horizontal Venting
The design of this furnace has been approved for horizontal
venting with the following mechanical vent systems:
• Tjernlund (sideshot) - Models SS1, SSC, SS2*
• Field Control - Model SWG-5S with CK63 Control Kit
Vent systems are available through the local distributor.
Refer to the manufacturer’s installation instructions
for proper installation procedures and service parts

* Barometric control must be installed in the horizontal
venting system and located within 18” of the ue outlet of
the furnace.
Barometric draft control must be used in the horizontal
venting (sidewall) system. It must be located within 18” of
the furnace ue outlet (see Figure 8).
Do not common vent with any other appliance when using
the sidewall system.
Maximum permissible vent length is 100 equivalent feet,
and minimum permissible length is 15 equivalent feet.
Calculate the equivalent vent pipe footage from the furnace
to the mechanical vent system by adding the straight vent
pipe length and equivalent elbow lengths together. Each
90° elbow is equivalent to 10’ of straight pipe; each 45°
elbow is equal to 5’ of straight pipe.
