a. Homeowner manual operation
b. 2 stage indoor thermostat*
c. Outdoor temperature switch*
• Certified for zero clearance installation
• Heavy duty 20ga panel construction
• 20” x 20” x 1” replaceable filter and mounting rack supplied
• 24v control circuit
• Time delay sequencer for optimum electric element start up
* Not supplied.

Hi/Econo Heat Switch

• This switch is provided on some models. It is located on the front of the furnace and provides the homeowner with the option of manually increasing or reducing the heating power of the furnace. It can be used to manually switch from "Hi" to "Econo" if less heating power is temporarily desired, depending on the outdoor temperature.

• This switch can also be controlled automatically by a suitable multi- or two-stage thermostat connected to the W1 (Econo) and W2 (Hi) terminals. Set the switch to "Econo" if a two stage or multi-stage thermostat is used.

• If a standard thermostat is connected across W1-R, a remote switch or an outdoor temperature switch can be connected across OT-W2 to switch from "Econo" to "Hi" as the outdoor temperature drops. Leave the furnace switch in "Econo" if a remote or outdoor temperature switch is used.

Clearance to Combustibles

The Newmac EH Electric Furnace may be installed in the up-flow, down-flow, horizontal-left or horizontal-right positions with the following clearances to combustibles:
Sides 0"
Rear 0"
Front (For Servicing) 24"
Warm Air Plenum and Duct 0"


Locate the furnace to provide:
• Best heat distribution
• Shortest supply cable*
• Least interference with present or future plans
* Use 75ºC copper supply sized according to the minimum ampacity. This should be connected to a seperate fused disconnect switch to power the furnace. Suitable ground must be provided. Follow local codes.
