Overview of E3 Furnace
E3E(-) Series electric furnaces are available in
two models. E3EH models are equipped with the
standard two-speed blower. E3EH models can
be easily converted for use with NORDYNE split-
system air conditioners and heat pumps. E3EB
models are air-conditioning ready; that is, they
are equipped with a multi-speed (four-speed)
blower, blower relay, and cabinet insulation kit.
See Table 3 for cooling and heat pump availability
with factory installed blower.
For typical unducted return air downfl ow applica-
tions, an air-conditioner or heat-pump coil can be
installed by mounting the coil directly on top of
the furnace without adding sheet metal cavities
or cutting and trimming wood panels.
A return air grille for closet or alcove installations
is available. For downfl ow alcove installations,
the grille (with frame provided) may be attached
to the top of the furnace and all paneling and
trim fl ushed to it. This installation provides an
access door for future installation of NORDYNE
air conditioning or heat pump coils on top of
the furnace.
