GAS HEATING SECTION (If Equipped)
Heat exchanger and exhaust system shall be constructed of
corrosion-resistant materials and shall be designed with
induced draft combustion with post purge logic and redundant
main gas valve. The heat exchanger shall be of the tubular
type, constructed of stainless steel for corrosion resistance and
allowing minimum mixed air entering temperature of 40 ºF.
Burners shall be of the in-shot type, constructed of
aluminumized steel. All gas piping shall enter the unit cabinet at
a single location through either the side or bottom, without any
field modifications. An integrated control board shall provide
timed control of indoor fan functioning and burner ignition.
Heating section shall be provided with the following minimum
protection:
a. Primary high-temperature limit switch.
b. Induced draft pressure switch.
c. Flame roll out switch(es) (manual reset).
d. Flame proving controls.
All gas heat models will meet the California requirement for
emissions of less than 40 nanograms per Joule (California
requirement on single phase models only).
