Tube Installation with Green Hose Clamps
Counterflow Units with a 17 1/2” cabinet width.
Insert approximately one inch of cut Tube 2 through left side
panel grommet hole and secure to Hose A with a hose clamp.
Insert uncut Tube 2 through remaining grommet hole and
secure to Hose B with a green hose clamp. NOTE: Tube
must reach bottom of trap.
All Units with a 21” and 24 1/2” cabinet width.
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 Section X,
Condensate Drain Lines and Drain Trap - Upright Drain Trap Mount-
ing.

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 alteration
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 sup-
plied 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 an UL approved bushing such as Heyco Liquid Tight or by
applying non-reactive UL approved 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 located in-
side the blower compartment. To make electrical connections through
the opposite side of the furnace, the junction box must be relocated
to the other side of the blower compartment prior to making electri-
cal 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.
CAUTION
E
DGES OF SHEET METAL HOLES MAY BE SHARP.
U
SE GLOVES A PRECAUTION
WHEN REMOVING HOLE PLUGS.
1. Remove the burner compartment door.
2. Remove and save the two screws securing the junction box
to the side panel.
3. Relocate junction box and associated plugs and grommets
to opposite side panel. Secure with screws removed in step
2.
