Remove the rubber cap from the side drain port on the rubber
elbow.
5.
Secure the short end of Hose B to rubber elbow side drain
port using a green hose clamp.
NOTE:
For left side drainage,
route hose to far left (down) side panel grommet holes.
NOTE:
Horizontal left side connections (when using new side port
drain elbow) does not require connecting a hose to the
induced draft blower housing.
6.
Cut 5 1/2 inches straight length from the long end of each
Tube 2.
7.
Insert approximately one inch of each Tube 2 through left
side panel grommet hole. Secure tubes to Hose A and Hose
B with a green hose clamps.
NOTE:
Tube must reach bottom
of trap. Ensure hoses and tubes maintain a downward slope
for proper drainage and that they are not kinked or binding.
For details concerning mounting of the drain trap, refer to

1.
Position the drain trap against side panel with drain tubes
inserted into trap. Note that the trap may be orientated with
the outlet facing either the furnace’s top cover or base pan.
2.
Secure drain trap to side panel at the dimples or crosshairs
located on either side of the grommet drain holes.
3.
Confirm that tubes reach bottom of drain trap and that all
hoses maintain a downward slope and are not kinked or
binding.
4.
Attach PVC drain line to drain trap outlet with either a 90°
elbow or coupling.

ARNESS
The wiring harness is an integral part of this furnace. Field alter-
ation to comply with electrical codes should not be required. Wires
are color and number 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 copper conductor.

ONNECTIONS
Before proceeding with electrical connections, ensure that the sup-
ply voltage, frequency, and phase correspond to that specified on
the unit rating plate. Power supply to the furnace must be N.E.C.
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 protec-
tion 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.
WARNING
I
N UPRIGHT UPFLOW INSTALLATIONS, THE DRAIN TRAP MUST BE MOUNTED ON
THE OPPOSITE SIDE OF THE UNIT FROM THE JUNCTION BOX.
T
HIS WILL
REDUCE THE RISK OF WATER REACHING THE JUNCTION BOX IN THE EVENT OF
A BLOCKED DRAIN CONDITION.
Connect hot, neutral, and ground wires as shown in the wiring dia-
gram located on the unit’s blower door. For direct vent applications,
the cabinet opening to the junction box must be sealed air tight us-
ing either a UL approved bushing such as Heyco Liquid Tight or by
applying a UL approved non-reactive sealant to bushing.
Line polarity must be observed when making field connections. Line
voltage connections can be made through either the right or left
side panel. The furnace is shipped configured for a left side (right
side for counterflows) electrical connection with the junction box lo-
cated inside the blower compartment. To make electrical connec-
tions through the opposite side of the furnace, the junction box must
be relocated to the other side of the blower compartment prior to
making electrical connections. To relocate the junction box, follow
the steps shown below.
NOTE:
Wire routing must not to interfere with circulator blower
operation, filter removal, or routine maintenance.
