tubing at the appropriate length to reach the drain
trap.
9. Connect the outlet from the drain trap to the
condensate drain piping using a ½" PVC tee. If a
condensate pump is used, make sure it is approved
for acidic condensate.
10. Prime the drain trap with water. This will ensure
proper furnace drainage at startup and will avoid
any recirculation of flue gas.
11. On the remaining 3 outlet stub, connect caps
(1x5/8" and 2x1/2"). These caps are provided in
the parts bag.

connection
The 3/16" stub just beside the drain of the condensate
box must be drilled or cut open. Use the supplied black
squared PVC tubing to connect the pressure switch (-0.2
in. w.c.) to this stub. (see figure 10)
The pressure switch must also be electrically connected
in series with the low fire pressure switch (top) using the
brown jumper furnished in the parts bag. Refer to figure
12 for more details.
3.5 MULTIPOSITION VENTING
DRAINAGE
All furnaces with horizontal exhaust vent piping must
have drain tee assembly and trap installed in the exhaust
pipe as close to the furnace as possible. See Figures 3,
6 and 10.
4 DUCT INSTALLATION
4.1 GENERAL REQUIREMENTS
The duct system should be designed and sized according
to accepted national standards such as those published
by: Air Conditioning Contractors Association (ACCA),
Sheet Metal and Air Conditioning Contractors National
Association (SMACNA) or American Society of Heating,
Refrigerating and Air Conditioning Engineers (ASHRAE).
Consult The Air Systems Design Guidelines reference
