ELECTRICAL CONNECTIONS

CAUTION
!
Protect from Property Damage
Do NOT connect the furnace line voltage to a GFCI pro-
tected circuit.
Failure to follow this warning could result in property
damage.
Make wiring connections to the unit as indicated on the
following field wiring diagram. As with all gas appli-
ances using electrical power, this furnace shall be con-
nected into a permanently live electric circuit. It is rec-
ommended that furnace be provided with a separate
"circuit protection device" electric circuit. The furnace
must be electrically grounded in accordance with local
codes or in the absence of local codes with the National
Electrical Code, ANSI/ NFPA 70 or CSA C22.1 Electrical
Code, if an external electrical source is utilized. The
integrated furnace control is polarity sensitive.
The hot leg of the 120V power supply must be con-
nected to the Black power lead as indicated on the wir-
ing diagram. Provision for hooking up an Electronic Air
Cleaner and/ or Humidifier is provided on the Inte-
grated Control.
Refer to the SERVICE FACTS literature and unit wir-
ing diagram attached to the furnace.

28
NOTE:
The maximum total cable length for the entire Com-
fort Control communicating system is 500 ft. 18
AWG. The maximum distance of any single cable
from a transformer is 250 ft. 18 AWG.
NON-COMMUNICATING WHOLE HOUSE AIR CLEANER
NOTE:
When connecting a *FD whole house air cleaner with
this furnace, order BAYACCECOMM101.
NOTE:
The BAYACCECOMM101 must be used when con-
necting a *FD whole house air cleaner to a furnace in
communicating mode. For 24 volt mode, see the in-
stallation in the whole house air cleaner Installer's
Guide.
NOTE:
The B/C terminal will require three wires to be con-
nected. Rather than connecting the three wired to
the low voltage terminal strip, create a pigtail using
a short length of thermostat wire and a wire nut
(field supplied) to attach to the B/C terminal.
