4. Connect each of condensate tubings to a stubs.
Use the furnished ½” and 5/8” tubing to cut the ap-
propriate length to get to the drain trap. The con-
densate 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. See figure 5.
5. Ensure the tubings are adequately connected to the
stubs.
6. Screw in place the drain trap with two head tapping
screws on the side of the furnace.
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. Such
a drain shall be in compliance with local building
codes or to a condensate pump approved for the
use with acidic furnace 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”). Those caps are furnished in
the part bag.
4.2 DOWNFLOW
CAUTION
It is STRONGLY RECOMMENDED to use the op-
tional 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.
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 left
side of the casing.
3. Place the drain trap gasket on drain trap.
4. Install the drain trap on the bottom left side, the
three outlet stubs of the drain trap toward the in-
terior of the furnace.
5. Screw in place the drain trap with two head tapping
screws on the side of the furnace.
6. Install two 1/2” black plastic caps on the unused
1/2” stubs of the drain trap.
7. Cut the required length of furnished 5/8” tubing and
connect one end on the port on the lower right side
of the condensate box. See figure 8
8. Connect the other end to the 5/8” stub of the drain
trap and secure the tubing on the gas manifold with
a tie wrap.
9. Connect the outlet from the drain trap to the con-
densate drain piping with a tee. DO NOT vent us-
ing the remaining 3 outlet stubs. Such a drain shall
be in compliance with local building codes or to a
condensate pump approved for the use with acidic
furnace condensate.
10. Make sure the unused stub ends of the drain trap
are plugged with furnished plastic caps.
4.3 HORIZONTAL RIGHT
1. Remove all tubings from the ID blower and vent col-
lector and block the stub openings with furnished
5/8” and 1/2” caps.
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. Install two 1/2” black plastic caps on the unused
stub openings on the drain trap inside the furnace.
See Figure 6.
6. Connect a small length of 5/8” PVC tube to the bot-
tom left of the condensate box and route with an
elbow to the drain trap. See Figure 6.
7. Connect the outlet from the drain trap to the con-
densate drain piping with a tee. DO NOT vent us-
ing the remaining 3 outlet stubs. Such a drain shall
be in compliance with local building codes or to a
condensate pump approved for the use with acidic
furnace 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”). Those caps are furnished in
the part bag.
4.4 HORIZONTAL LEFT
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.
