1. Maximum allowable limits listed on individual lengths
for inlet and ue and NOT a combination.
2. Minimum requirement for each vent pipe if ve (5)
feet in length and one elbow/tee.
3. Tee used in the vent/ue termination must be
included when determining the number of elbows in
the piping system.
4. 2 ½” or 3” diameter pipe can be used in place of 2”
diameter pipe.
5. Increased Clearance Conguration using (2) 45
deg. Long Sweep elbows should be considered
equivalent to one 90 deg. elbow.
6. One 90° elbow should be secured to the combustion
air intake connection.
The vent pipe outlet is sized to accept 2” pipe. Secure vent
pipe directly into the furnace tting with the appropriate
glue. Alternately, a small section of 2” pipe may be glued
in the furnace socket and a rubber coupling installed to
allow removal for future service. Piping should be routed in
a manner to avoid contact with refrigerant lines, metering
devices, condensate drain lines, etc. If necessary,
clearances may be increased by creating an oset using
two 45° elbows (Figure 7).
45 DEGREE
ELBOWS
If the furnace is being installed without a combustion air
pipe, a 90° elbow should be used on the combustion air
intake to guard against blockage.
On up ow / horizontal models, secure the combustion
air intake pipe to the air intake coupling using a rubber
coupling supplied with the furnace. The rubber coupling
may be omitted by inverting the intake coupling and gluing
pipe directly to it. Piping may also be glued to the intake
coupling in its original position by using a plastic coupling.
On counterow units secure the combustion air intake
pipe to the air intake coupling using the rubber coupling
and worm gear hose clamps provided with the unit. The
counterow rubber coupling allows service removal of air
intake piping internal to the furnace blower compartment.
The combustion air intake pipe can also be secured
directly to the counterow unit air intake pipe coupling.
