Heater Gas Type SetupThe heater will come equipped from the factory for whichever gas type you choose.
NOTE: A free conversion kit is also included in case you need to change the gas type in the future.
Stainless Steel Heat ExchangerIf the heater will be in a corrosive environment, upgrading to a stainless steel heat exchanger will increase the life of the heater. Units with stainless steel heat exchangers ship direct from Sterling. The current ship time is listed in the option selection area above. Must be ordered with heater.
2 Stage Gas ValveHeaters with a two-stage gas valve start on the 1st stage at half output and only switch to the 2nd stage, full output, if the temperature inside the room continues to drop. This allows the heater to run more efficiently saving gas and money. Units with 2 stage valves ship direct from Sterling. The current ship time is listed in the option selection area above. Must be ordered with heater.
ElevationIf the heater will be installed at a location that is over 5000' above sea level, Sterling makes a special high altitude model for this application. Units setup for high altitude (above 5000') ship direct from Sterling. The current ship time is listed in the option selection area above. Must be ordered with heater.
