GAS HEAT
These gas-fired heaters have aluminized-steel or
optional stainless steel, tubular heat exchangers with
spark ignition with proven pilot.
All gas heaters are shipped from the factory equipped
for natural gas use. See Gas Heat Application Data
Table.
For natural gas heating installations in locations requir-
ing low NOx emissions, Accessory model 1LN0406
must be used.
NOTE: Gas Heaters are shipped available for natural gas, but can be converted to L.P. with Kit Model No. 1NP0440 or 1NP0485 (2
Stage). All furnaces meet the latest California seasonal efficiency requirements.
