Please note that each furnace is factory inspected before shipping in order to ensure that every component is operating efciently.
The “SFECM’’ series electric furnace is available in several models of various heating capacity (from 10 to 30 kW). All these models adapt easily
to many applications and are suitable for horizontal, upow and downow operations (see the gures below). When installed in vertical
downow position, use only ‘‘L’’ or ‘‘T’’ shaped plenum without openings or registers directly below the unit.
LOCATION
You must install the furnace on a dry and solid base, in an area free of ammable liquids or vapors and combustible materials. You must
indicate to the furnace user the location of the switches and disconnects. He must be able to quickly identify them in case of an emergency.
Moreover, the furnace should be located as centrally as possible in the area to heat in order to optimize air dissipation in all the rooms.
CLEARANCE
This furnace is approved for ‘‘zero inch’’ clearance. Meaning that you can install it directly against a wall. Ducts for models of 22.5 kW and
less can also be installed with a zero inch clearance (0 inch). However, ducts for models of 27.5 kW and more must have a 1-inch clearance
for the rst 36 inches of duct. From 37 inches, this clearance can be reduced to 0 inch. Please refer to the codes effective in your region if
you have any questions concerning clearances.
Since it is necessary to open the door in the front to perform the furnace maintenance inspection, you must leave at least a 24-inch
clearance in front of this door.
