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
compartment of the unit with the heater elements extending
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 11 for
minimum CFM limitations and to Tables 8 through 9 for elec-
