An accessible manual shutoff valve MUST be installed upstream
of furnace gas controls and within 6 ft of furnace. A 1/8-in. NPT
plugged tapping, accessible for test gage connection, MUST be
installed immediately upstream of gas supply connection to
furnace and downstream of manual shutoff valve.
NOTE: The gas valve inlet pressure tap connection is suitable to
use as test gage connection providing test pressure DOES NOT
exceed maximum 0.5 psig (14-in. wc) stated on gas valve. (See
Fig. 33.) Piping should be pressure tested in accordance with
NFGC, local and national plumbing and gas codes before furnace
is attached. In Canada, refer to current edition of NSCNGPIC.
VIII. ELECTRICAL CONNECTIONS
See Fig. 21 for field wiring diagram showing typical field 115-v
wiring. Check all factory and field electrical connections for
tightness.
WARNING: Blower access panel door switch opens
115-v power to control. No component operation can
occur. Do not bypass or close switch with panel removed.
Failure to follow this warning could result in personal
injury or death.

A. 115–v Wiring
Before proceeding with electrical connections, make certain that
voltage, frequency, and phase correspond to that specified on unit
rating plate. Also, check to be sure that service provided by utility
is sufficient to handle load imposed by this equipment. Refer to
rating plate or Table 6 for equipment electrical specifications.
Make all electrical connections in accordance with National
Electrical Code (NEC) ANSI/NFPA 70-1999 and any local codes
or ordinances that might apply. For Canadian installations, all
electrical connections must be made in accordance with Canadian
Electrical Code CSA C22.1 or authorities having jurisdiction.
CAUTION: Do not connect aluminum wire between
disconnect switch and furnace. Use only copper wire.
Use a separate, fused branch electrical circuit containing a properly
sized fuse or circuit breaker for this furnace. See Table 6 for wire
size and fuse specifications. A disconnecting means must be
located within sight from and readily accessible to furnace.
NOTE: Proper polarity must be maintained for 115-v wiring. If
polarity is incorrect, control LED status indicator light will flash
rapidly and furnace will NOT operate.
