5. Remove the rubber cap from the side drain port on the rubber
elbow.
6. Secure the short end of Hose B to the rubber elbow side
drain port using a green hose clamp.
NOTES:
■
For left side drainage, route Hose B to the far left (down)
side panel grommet holes.
■
Horizontal left side connections (when using a new side
port drain elbow) does not require connecting a hose to
the induced draft blower housing.
7. Cut 5
¹⁄₂
" (14 cm) straight length from the long end of each
Tube 2. Discard radius ends.
8. Insert approximately 1" (2.5 cm) of each Tube 2 through the
left side panel grommet hole.
9. Secure the tubes to Hose A and Hose B with the green hose
clamps.
NOTE: Tube must reach bottom of trap.
NOTE: Ensure that the hoses and tubes maintain a downward
slope for proper drainage and are not kinked or bound.
For details concerning the mounting of the drain trap, refer to
“Horizontal Drain Trap Mounting” in this section.

1. Position the drain trap against the side panel with the drain
tubes inserted into the trap.
NOTE: The trap may be orientated with the outlet facing
either the furnace’s top cover or base pan.
2. Secure the drain trap to the side panel at the dimples or
crosshairs located on either side of the grommet drain holes.
3. Confirm that the tubes reach the bottom of the drain trap and
that all of the hoses maintain a downward slope and are not
kinked or binding.
4. Attach the PVC drain line to the drain trap outlet with either a
90° elbow or coupling.
ELECTRICAL CONNECTIONS
Wiring Harness
The wiring harness is an integral part of this furnace. Field
alteration to comply with electrical codes should not be required.
Wires are color coded for identification purposes. Refer to the
wiring diagram for wire routings.
If any of the original wire as supplied with the furnace must be
replaced, it must be replaced with wiring material having a
temperature rating of at least 105°C. Any replacement wiring
must be a copper conductor.
115-Volt Line Connections
Before proceeding with electrical connections, ensure that the
supply voltage, frequency and phase correspond to that
specified on the unit rating plate. Power supply to the furnace
must be NEC Class 1, and must comply with all applicable
codes. The furnace must be electrically grounded in accordance
with local codes or, in their absence, with the latest edition of The
National Electric Code, ANSI NFPA 70 and/or The Canadian
Electric Code CSA C22.1.
Use a separate fused-branch electrical circuit containing properly
sized wire, and fuse or circuit breaker. The fuse or circuit breaker
must be sized in accordance with the maximum overcurrent
protection specified on the unit rating plate. An electrical
disconnect must be provided at the furnace location.
NOTE: Line polarity must be observed when making field
connections.
Connect hot, neutral and ground wires as shown in the wiring
diagram located on the unit’s blower door. For direct vent
applications, the cabinet opening to the junction box must be
sealed air tight using either an UL Listed/CSA approved bushing
such as Heyco Liquid Tight or by applying non-reactive UL
Listed/CSA approved sealant to bushing.
