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 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 protec-
tion specified on the unit rating plate. An electrical disconnect must
be provided at the furnace location.
Line voltage wiring must enter into the junction box provided with the
furnace.
NOTE: 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 right side electri-
cal connection. To make electrical connections through the oppo-
site side of the furnace, the junction box must be relocated to the left
side prior to making electrical connections. To relocate the junction
box, perform the following steps.
T
O PREVENT PERSONAL INJURY OR DEATH DUE TO ELECTRIC SHOCK,
DISCONNECT ELECTRICAL POWER.
1. Remove both doors from the furnace.
2. Remove and save the screws holding the junction box to the
right side of the furnace.
3. Disconnect the hose from the pressure switch. Leave the other
end attached to the induced draft blower.
4. Remove two wires entering junction box from blower deck.
5. Swap locations of the two bushings in the junction box.
6. Rotate the junction box 180 degrees so the access panel
continues to face forward. The open snap bushing should
now be at the bottom.
7. Insert the two wires through the open bushing in the bottom
of the junction box.
8. Attach the junction box to the left side of the furnace, using
the screws removed in step 2.

10. Check the location of the pressure hose and all wiring. Confirm
that it will not be damaged by heat from the burners or by the

rotation of the fan. Also confirm that wiring location will not
interfere with filter removal or other maintenance.
After the junction box is in the desired location, use washers to con-
nect field-supplied conduit to the junction box in accordance with
NEC and local codes. Connect hot, neutral, and ground wires as
shown in the furnace wiring diagram. The wires and ground screw
are located in the furnace junction box.
Low voltage wires may be connected to the terminal strip as shown
in Figure 10.
IMPORTANT NOTE: To avoid possible equipment malfunction, route
the low voltage wires to avoid interference with filter removal or other
maintenance.

T
O AVOID THE RISK OF INJURY, ELECTRICAL SHOCK OR DEATH, THE FURNACE
MUST BE ELECTRICALLY GROUNDED IN ACCORDANCE WITH LOCAL CODES OR,
IN THEIR ABSENCE, WITH THE LATEST EDITION OF THE
C
ODE.
To ensure proper unit grounding, the ground wire should run from
the furnace ground screw located inside the furnace junction box all
the way back to the electrical panel. NOTE: Do not use gas piping
as an electrical ground. To confirm proper unit grounding, turn off
the electrical power and perform the following check.
