Overview of E2 Furnace

E2E(-) Series electric furnaces are available in
two models. E2EH models are equipped with
the standard two-speed blower. E2EH models
can be easily converted for use with NORDYNE
split-system air conditioners and heat pumps.
E2EB models are air-conditioning ready; that is,
they are equipped with a multi-speed (four­speed) blower, blower relay, and cabinet insu­lation kit. See Table 3 for cooling and heat pump
availability with factory installed blower.

For typical non-ducted return air downflow
applications, 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 downflow alcove installations,
the grille (with frame provided) may be attached
to the top of the furnace and all paneling and trim
flushed to it. This installation provides an ac­cess door for future installation of NORDYNE
air conditioning or heat pump coils on top of the
furnace.

Power entrance for all models may be through
the right side or through the bottom of the unit
(when viewing the unit in a downflow position).
