115-V Wiring
Furnace must have a 115-v power supply properly connected and
grounded.
NOTE:
Proper polarity must be maintained for 115-v wiring. If polarity
is incorrect, control LED status indicator light will flash rapidly (Status
Code 10) and furnace will
NOT
operate.
Verify that the 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
for equipment electrical specifications.
USA Installations
: Make all electrical connections in accordance with
the current edition of the National Electrical Code (NEC) NFPA 70 and
any local codes or ordinances that might apply.
Canada Installations
: Make all electrical connections in accordance
with the current edition of the Canadian Electrical Code CSA C22.1 and
any local codes or ordinances that might apply.

WARNING
!
ELECTRICAL SHOCK AND FIRE HAZARD
Failure to follow this warning could result in personal injury, death, or
property damage.
The cabinet MUST have an uninterrupted or unbroken ground
according to current edition of NEC NFPA 70 or local codes to
minimize personal injury if an electrical fault should occur. In Canada,
refer to the current edition of Canadian Electrical Code CSA C22.1.
This may consist of electrical wire, conduit approved for electrical
ground or a listed, grounded power cord (where permitted by local
code) when installed in accordance with existing electrical codes. Refer
to the power cord manufacturer’s ratings for proper wire gauge. Do not
use gas piping as an electrical ground.
