7. (Draining the Vent Elbow) Remove rubber plug from
vent – drain elbow side port.
8.
The unused vent-drain elbow drip leg port must be
plugged to prevent flue gases from escaping.
Insert
rubber plug removed in step 7 into the 100° elbow..
(Inserting a blunt tool such as a 3/16’’ Allen wrench
into the center of the rubber plug will stretch the plug
and allow complete insertion)
9. Place radius end of hose #4 on the side port of vent –
drain elbow and secure with a gold clamp.
10. Insert a ½” diameter PVC pipe (factory installed) into
hose #4 and secure with a gold clamp.
11. Insert the non-grommet end of hose #5 (factory
installed) from outside the cabinet in the back drain
hole.
12. Insert 100º elbow in hose #5 and secure with a red
clamp.
13. Locate hose #4 and cut a cut off a 4” straight section
and discard the radius end.
14. Connect the 4” straight section of hose #4 to the 100º
elbow and the PVC pipe and secure with red clamps.
15. Connect the hoses to the trap inlets and secure with
silver clamps, drain trap outlet must point to the
original bottom of the furnace.
16. Using the two sheet metal screws provided in the
cabinet, secure the trap to the furnace.
17. Refer to Field Supplied Drain section for instructions
on field supplied / installed drain on outlet of
furnace trap.

The wiring harness is an integral part of this furnace. 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 re-
placed with wiring material having a temperature rating of at
least 105° C. Any replacement wiring must be a copper conduc-
tor.

ONNECTIONS
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 fur-
nace must be NEC Class 1, and must comply with all appli-
cable 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 prop-
erly sized wire, and fuse or circuit breaker. The fuse or
circuit breaker must be sized in accordance with the maxi-
mum overcurrent protection specified on the unit rating plate.
An electrical disconnect must be provided at the furnace
location.
Connect hot, neutral, and ground wires as shown in the wir-
ing 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 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 connec-
tions. Line voltage connections can be made through either
the right or left side panel. The furnace is shipped config-
ured for a right side (left side for counterflows) electrical
connection with the junction box located inside the burner
compartment. To make electrical connections through the
opposite side of the furnace, the junction box must be relo-
cated to the other side of the burner compartment prior to
making electrical connections. To relocate the junction box,
follow the steps shown below.
NOTE:
Wire routing must not interfere with circulator blower
operation, filter removal, or routine maintenance.
