A WARNING
Never purge a line into a combustion chamber. Never use
matches, candles, flame, or other sources of ignition for the
purpose of checking leakage. Use a soap-and-water solution
to check for leakage. Failure to follow this warning can cause
a fire, explosion, personal injury, or death.
Step 6— Electrical Connections
115-V WIRING — Refer to the unit rating plate or Table 5 for
equipment electrical requirements. The control system requires an
earth ground for proper operation.
A CAUTION
Do not connect aluminum wire between disconnect switch
and furnace. Use only copper wire.
Make all electrical connections in accordance with the National
Electrical Code ANSI/NFPA 70-1993 and local codes or ordi­
nances that might apply. For Canadian installations, all electrical
connections must be made in accordance with CSA C22.1 Cana­
dian Electrical Code, or authorities having jurisdiction.
A WARNING
The cabinet MUST have an uninterrupted or unbroken ground
according to National Electrical Code, ANSI/NFPA 70-1993
and Canadian Electrical Code, CSA C22.1 or local codes to
minimize personal injury if an electrical fault should occur.
This may consist of electrical wire or conduit approved for
electrical ground when installed in accordance with existing
electrical codes. Do not use gas piping as an electrical ground.
The auxiliary junction box can be moved to the right-hand side of
the furnace when a right-side power supply is desired. Remove the
2 screws holding the auxiliary junction box. Mount the junction
box on the right-hand side of the furnace (holes have been
predrilled in casing). The blower door interlock switch must also
be moved to the right side of the furnace due to the length of the
wiring harness. When moved, tuck the wiring harness behind the
clip provided to keep extra wire lengths out of the way.
NOTE:
Proper polarity must be maintained for 115-v wiring. If
polarity is incorrect, the microprocessor will ^shut off gas flow
shortly after the completion of ignition trial period.
