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. SeeTable 3 for cooling and heat pump availability with factory installed blower.

For typical unducted return air downflow 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.
