Electrical Requirements

WARNING
Electrical Shock Hazard
Electrically ground furnace.
Connect ground wire to green pigtail lead.
Failure to do so can result in death or electrical shock.
NOTE: Use copper conductors only.
All field wiring must be done in accordance with National
Electrical Code, applicable requirements of UL and local
codes.
Electrical wiring, disconnect means and overcurrent
protection are to be supplied by the installer. Refer to the
electric furnace rating plate for maximum overcurrent
protection, minimum circuit ampacity, as well as operating
voltage.
The power supply must be sized and protected according to
the specifications supplied on the product.
This electric furnace is factory configured for 240 Volt, single
phase, 60 cycles. For 208 Volt applications, see "208 Volt
Conversion" in the "Make Electrical Connections" section.

Duct Work Requirements

Install the conditioned air plenum, ducts and air filters (not
provided) in accordance with NFPA 90B Standard for the
Installation of Warm Air Heating and Air-Conditioning
Systems (latest edition).
The electric furnace is provided with flanges for the
connection of the plenum and ducts.
Air filters must be listed as Class 2 furnace air filters.
Supply and return duct work must be adequately sized to
meet the system's air requirements and static pressure
capabilities. Duct work should be insulated with a minimum
of 1 in. thick insulation with a vapor barrier in conditioned
areas or 2 in. minimum in unconditioned areas.
Supply plenum should be the same size as the flanged
opening provided around the blower outlet and should
extend ideally at least 3 ft from the electric furnace before
turning or branching off plenum into duct runs.The plenum
forms an extension of the blower housing and minimizes air
expansion losses from the blower.
