Will the supply house you purchase the boiler make a call to engineering or a factory service person that takes care of your area. Not everything is in a install manual.

Just remember with a two pole contactor one leg will be hot all the time power is on. Also good time to check blower and evap coil for cleanliness. If coil as a expansion valve check the bulb for tightness on the line and insulate it.

Would imagine that if you contacted any other hyper heat manufacturer they would have the same limitations for operating temps. Refrigeration systems need certain compression ratio to operate and return oil back to the compressor along with velocity of the refrigerant. Even a simple gas...
