you must consult the Reznor high-altitude derate tables and coordinate with a venter pressure switch adjustment if necessary

you must verify the specific temperature rating and mounting bracket style required by the unit's data plate

this dual-terminal SPST pressure switch functions as a normally open control that proves the draft inducer motor is moving sufficient combustion air through the heat exchanger

3-Pole Switching: Simultaneously controls all three power legs to ensure balanced load distribution and motor protection

This 5 cell heat exchanger is engineered with precision to facilitate maximum thermal transfer while ensuring combustion gases remain isolated from the circulating air

Siemens Industrial Controls 3UB81234EW2 Relay 326058-758 you must consult the ReznorThe Siemens 3UB81234EW2 is a high performance ESP200 solid state overload relay designed for precise motor protection in industrial HVACR and pumping applications. Engineered to replace legacy ESP100 units without enclosure modifications, this 3 phase overload relay handles a wide current range of 10 to 40 Amps. Unlike standard bimetallic options, the solid state design is ambient insensitive, virtually eliminating nuisance tripping caused by varying
