2. Remove the oblong knock-out from the bottom mid-
dle side of the casing.
3. Place gasket on the drain trap.
4. Screw in place the drain trap with 2 Tek tapping
screws to the side of the furnace. The drain trap
must be vertical.
5. Drill open the new bottom stub of the ID blower (if
not already open). Be sure to remove all debris.
6. Reroute the ID blower drain tube from the bottom of
the ID blower casing to one of the 1/2” stub of the
drain trap. Use the furnished 1/2” tubing to cut the
appropriate length to get to the drain trap.
7. Reroute the condensate box drain tubing from the
bottom of the condensate box to one of the 5/8”
stub of the drain trap. Use the furnished 5/8” tubing
to cut the appropriate length to get to the drain trap.
8. Reroute the vent collector drain tube to one of the
1/2” stubs of the drain trap. Use the furnished 1/2”
tubing to cut the appropriate length to get to the
drain trap.
9. Connect the outlet from the drain trap to the con-
densate drain piping using a ½” PVC tee. Such
a drain shall be in compliance with local building
codes or to a condensate pump approved for use
with acidic furnace 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”). Those caps are furnished in
the part bag.

VENTING DRAINAGE
All furnaces with horizontal exhaust vent piping must
have a PVC 636 drain tee assembly and trap installed
in the exhaust pipe as close to the furnace as possible.
See Figures 7,6 and 8

MULTIPOSITION PRESSURE
SWITCH CONNECTION
The 3/16 stub just beside the drain of the condensate
box must be drilled or cut open. The black squared PVC
tubing of the pressure switch (-0.2 in w.c.) must be con-
nected to this stub. This tubing is furnished with the fur-
nace. See Figures 7,6 and 8
The pressure switch must now be electrically connected
in series with the low fire pressure switch (top) with the
brown jumper furnished in the part bag. See Figure 9
and wiring diagrams.
