5. Install two 1/2” black caps on the unused inlets of the
drain trap inside the furnace.
6. Connect a small length of 5/8" condensate tubing to the
condensate box and route with an elbow to the drain trap.
Make sure it can drain properly.
7. Connect the outlet of the drain trap to the condensate
drain piping with a tee. DO NOT vent using the remaining
3 inlets. If a condensate pump is used, make sure it is
approved for acidic condensate.
8. Prime the drain trap with water.
This will ensure
proper furnace drainage at startup and will avoid any
recirculation of flue gas.
9. On the remaining 5 inlets, connect black caps (1x5/8" and
2x1/2"). These caps are provided in the parts bag.

connection
Figure 9 – Horizontal right pressure switch tubing
The 3/16" stub just beside the drain of the condensate box must
be drilled or cut open. The black squared PVC tubing must
connect the pressure switch (-0.2 in w.c.) to this stub. This
tubing is provided with the furnace. Refer to figure 6 to see
which port is associated to the horizontal right position.
The pressure switch must also be electrically connected in
series with the low fire pressure switch (top) using the brown
jumper provided in the parts bag. Refer to figure8 (Horizontal
right pressure switch connection) for more details.

REFER TO FIGURE 10 FOR INSTALLATION DETAILS.
1. Remove all tubing from the ID blower, condensate box
and vent collector and block the stub openings with
furnished 5/8” and 1/2” black caps.
2. Remove the oblong knock-out from the bottom middle
side of the casing. (An alternate knock-out is available
on the furnace top panel if space is constraint)
3. Place gasket on the drain trap.
4. Screw in place the drain trap with 2 self-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.
Cut the provided 1/2" tubing at the appropriate length to
reach the drain trap.
7. Reroute the condensate box drain tubing from the bottom
of the condensate box to the 5/8” stub of the drain trap.
Cut the provided 5/8" tubing at appropriate length to
reach the drain trap.
