Optional Electric Heat

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 in 
to the supply air chamber.

Fuses are supplied, where required, by the factory. Some kW 
sizes require fuses and others do not. refer to Table 11 for 
minimum CFM limitations and to Table 9 for electrical data.

Optional Gas Heat

These gas-fired heaters have aluminized-steel or optional 
stainless steel, tubular heat exchangers with spark ignition.

NOTE: 

On VAV units, individual VAV boxes must be fully open 
in heating mode to insure airflow falls within specified 
Temperature Rise range.

Gas Piping

Proper sizing of gas piping depends on the cubic feet per hour 
of gas flow required, specific gravity of the gas and the length of 
run. "National Fuel Gas Code" Z223.1 (in U.S.A.) or the current 
Gas Installation Codes CSA-B149.1 (in Canada) should be 
followed in all cases unless superseded by local codes or gas 
utility requirements. Refer to the Pipe Sizing Table 12. The 
heating value of the gas may differ with locality. The value 
should be checked with the local gas utility.
