3 INSTALLATION
To ensure proper drainage of the condensate when
installed in position other than upflow, the furnace
MUST be tilted. Refer to figures corresponding to the
position of the furnace in the following sections.
CAUTION
PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in water
spillage and/or property damage.
For any position other
multiposition pressure switch must be connected
pneumatically to the
electrically to the control to allow the furnace
to stop in the event of drain blockage.
3.1 UPFLOW
The furnace is factory built for upflow position. In this
position, the drain trap can be installed on the right or left
side depending on air return duct. When installing the
furnace in the upflow position, make sure it is leveled or
tilted foward.
In the upflow orientation, the drain trap can be installed
to the right or to the left of the furnace. The location of
the drain trap is dependent of the return duct connection.
The furnace must be perfectly leveled or slightly leaned
forward to help drain condensate.

See figure 1 and read the following instructions:
1. Remove the oblong knock-out from the right side of
the casing.
2. Place the drain trap gasket on drain trap.
3. Install the drain trap on the right side. See figure 1.
4. Screw in place the drain trap with two head tapping
screws on the right side of the furnace.
5. Connect the three stubs to the condensate tubings
already in place in the furnace.
6. 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 3 outlet stubs.
7. Prime the drain trap with water. This will ensure
proper furnace drainage at startup and will avoid
any recirculation of flue gas.
8. On the remaining 3 outlet stub, connect caps
(1x5/8" and 2x1/2"). Those caps are furnished in
the parts bag.
9. If a condensate pump needs to be use, make sure
it is suited for acidic condensate.
