2. Place the drain trap gasket on the drain trap.
3. Install the drain trap on the left side, the three outlet
stub of the drain trap toward the interior of the
furnace.
4. Connect each condensate tubing to a stub. Use the
furnished ½” and 5/8” tubing to cut the appropriate
length to reach the drain trap.
The condensate
tubing from the condensate box is 5/8” and it must
be connected to the 5/8” stub of the drain trap. The
condensate tubing from the ID blower and the vent
flange are ½” and are connected to the ½” stubs of
the drain trap.
5. Ensure the tubings are adequately connected to the
stubs and are correctly sloped to the drain trap.
Left side connection requires special attention to
the slope of condensate tubing through the furnace.
6. Screw the drain trap in place with two head tapping
screws on the furnace side.
7. Connect the outlet drain from the drain trap to an
additional condensate tubing using a ½” tee for an
adequate drainage of the condensate. DO NOT
vent using the remaining three outlet stubs. 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 3 outlet stub, connect caps
(1x5/8” and 2x1/2”). These caps are provided in
the parts bag.
3.2 DOWNFLOW
SEE FIGURE 3 FOR INSTALLATION DETAILS
CAUTION
It is STRONGLY RECOMMENDED to use the
optional downflow base to ensure the 1” clearance
around the supply duct going through the floor
and the proper slope of the furnace for condensate
drainage. Also, the base allows sufficient spacing
for the venting and the drain trap.
When installing the furnace in downflow position, make
sure the furnace is tilted foward to make it drain properly.
Plan your installation to have at least 1.0 ft. of clearance
under the installed furnace to put the exhaust pipe
drainage and drain trap.
Figure 3 – Downflow position
3.2.1 Downflow condensate drain trap
connection
1. Remove all condensate tubing from the inducer
blower, condensate box and vent collector. Block
the openings with the provided 5/8” and 1/2” black
caps. In the downflow position, the only connection
to the drain trap comes from the condensate box.
The inducer blower will be drained through the
exhaust pipe.
2. Remove the downflow drain trap knock-out.
3. Place the drain trap gasket on the drain trap.
4. Install the drain trap.
5. Screw the drain trap in place with two head tapping
screws on the side of the furnace.
6. Install two 1/2” black plastic caps on the unused
1/2” inlets of the drain trap inside the furnace.
7. Cut the required length of 5/8” tubing and connect
one end on the downflow port of the condensate
box. See figure 3 for port location.
8. Connect the other end to the 5/8” inlet of the drain
trap and secure the tubing on the gas manifold with
a tie wrap.
9. Connect the outlet of the drain trap to the
condensate drain piping with a tee. DO NOT vent
using the remaining 3 inlet of the drain trap. If a
condensate pump is used, make sure it is approved
for acidic condensate.
10. Make sure the 5 unused inlets of the drain trap are
plugged with provided plastic caps.
