6. 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.
7. A “Blocked Drain Kit” MUST be installed for left side down
installations. The kit includes a front cover pressure switch
that must be used to protect against a blocked drain
condition. Install the front cover pressure switch per the
instructions included with the “Blocked Drain Kit”. Failure to
install the “Blocked Drain Kit” will void the warranty and could
lead to bodily injury or death.
For details concerning mounting of the drain trap, refer to Section
X, Condensate Drain Lines and Drain Trap - Horizontal Drain Trap
Mounting (Left or Right Side Panel).
HORIZONTAL DRAIN TRAP MOUNTING (LEFT OR RIGHT SIDE PANEL)
NOTE: This furnace is shipped from the factory as a Dedicated
Upflow. A “Blocked Drain Kit” is available and MUST BE USED if the
furnace is installed Horizontal Left or Horizontal Right. Check the
Serial/ Rating Plate on the furnace for the Kit P/N.
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.

BEFORE SERVICING OR CHANGING ANY ELECTRICAL
WIRING .

L ABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING
CONTROLS . W IRING ERRORS CAN CAUSE IMPROPER AND
DANGEROUS OPERATION . V ERIFY PROPER OPERATION AFTER
SERVICING .
CAUTION
WIRING H 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-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 re-
placement wiring must be copper conductor.
115 VOLT L INE CONNECTIONS
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 pro-
tection 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.
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 .
WARNING
Connect hot, neutral, and ground wires as shown in the wiring
diagram located on the unit’s blower door. For direct vent applica-
tions, the cabinet opening to the junction box must be sealed air
tight using either a UL approved bushing such as Heyco Liquid
Tight or by applying a UL approved non-reactive sealant to bush-
ing.
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
electrical connection with the junction box located inside the burner
compartment. To make electrical connections through the oppo-
site side of the furnace, the junction box must be relocated 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 to interfere with circulator blower
operation, filter removal, or routine maintenance.
E DGES OF SHEET METAL HOLES MAY BE SHARP . U SE GLOVES AS A
PRECAUTION WHEN REMOVING HOLE PLUGS .
WARNING
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.
