Optional electric heat

The factory-installed heaters are wired for single point power
supply. You only need to bring the power supply into the single
point terminal block.

Optional gas heat

The optional gas-fired heaters have aluminized-steel or optional
stainless steel, tubular heat exchangers with spark ignition.
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.
Follow the "National Fuel Gas Code" Z223.1 (in U.S.A.) or the
current Gas Installation Codes CSA-B149.1 (in Canada) in all
cases unless they are superseded by local codes or gas utility
requirements.
See Table 15, Gas pipe sizing - capacity of pipe, on page 36.
The heating value of the gas may vary by locality. You must
check the value with the local gas utility.
