ELECTROSTATIC DISCHARGE (ESD)
Precautions and Procedures
CAUTION
Electrostatic discharge can affect electronic components.
Take precautions during furnace installation and service
to protect the furnace's electronic controls. Precautions
will help to avoid control exposure to electrostatic
discharge by putting the furnace, the control and the
technician at the same electrostatic potential. Neutralize
electrostatic charge by touching hand and all tools on an
unpainted unit surface, such as the gas valve or blower
deck, before performing any service procedure.
WARNING
Electric Shock Hazard. Can cause
injury or death. Unit must be properly
grounded in accordance with national and
local codes.
WARNING
Fire Hazard. Use of aluminum wire with this product may
result in a fire, causing property damage, severe injury
or death. Use copper wire only with this product.
CAUTION
. Failure to use properly sized wiring and circuit breaker
may result in property damage. Size wiring and circuit
breaker(s) per Product Specifications bulletin (EHB) and
unit rating plate.
EXTERIOR MAKE-UP BOX
(FIELD PROVIDED RIGHT SIDE)
FIGURE 43
The unit is equipped with a make-up box on the left hand
side of the cabinet. A field-provided make-up box can be
installed on the exterior of the right side of the furnace to
facilitate installation. If the make-up box is moved to the
right side, clip the wire ties that bundle the wires together
and install on the outside of the cabinet. See figure 43.
The excess wire must be pulled into the blower compart-
ment. Secure the excess wire to the existing harness to
protect it from damage.
Refer to figure 46 for unit field wiring. See figures 44 and
45 for icomfort Wi-Fi thermostat wiring in communicating
applications. Table 14 shows DIP switch and on-board link
settings for non-communicating thermostat applications.
Typical wiring schematic is shown in figure 46.
NOTE - Unit nameplate states maximum current draw.
See table for maximum over-current protection.

2 - Holes are on both sides of the furnace cabinet to
facilitate wiring.
3 - Install a separate (properly sized) disconnect switch
near the furnace so that power can be turned off for
servicing.
4 - Before connecting the thermostat or the power
wiring, check to make sure the wires will be long
enough for servicing at a later date. Remove the
blower access panel to check the length of the wire.
5 - Complete the wiring connections to the equipment.
Use the provided unit wiring diagram and field
wiring diagram shown in figure 46 and table 14. Use
18-gauge wire or larger that is suitable for Class II
rating for thermostat connections.
6 - Electrically ground the unit according to local codes
or, in the absence of local codes, according to the
current National Electric Code (ANSI/NFPA No. 70)
for the USA and current Canadian Electric Code
part 1 (CSA standard C22.1) for Canada. A green
