ELECTRIC HEAT ACCESSORIES

Electric heaters are available as field installed accessories.
Refer to electric heat instructions for installation. These heat-
ers mount in the heat compartment with the heating elements
extending into the supply air chamber. All electric heaters are
fused and intended for use with single point power supply.

The factory-installed heaters are wired for single point power
supply. Power supply need only be brought into the single
point terminal block.
These CSA approved heaters are located within the central

into the supply air chamber.
Fuses are supplied, where required, by the factory. Some kW
sizes require fuses and other do not. Refer to Table 15 for
