Designation for a Digital heater using propane gas is “EP”; a Digital heater using natural gas is “EN”. Designation for a Millivolt heater using propane gas is “MP”; a Millivolt heater using natural gas is “MN”. Prefix “C” is for cast iron (ASME) headers; “P” is for plastic (polymer) headers.

Suffix “X” is for cupro-nickel tubing; “C” is for copper tubing.

EXAMPLE: P-R406A-EN-X= Plastic headers, 406 model size, digital, natural gas, cupro-nickel. Reduce input 4% for each 1000 ft above sea level when installed above 2000 ft elevation.

For Canada, no de-rating is required for elevations up to 4500 ft Plastic (polymer) headers cannot be used for ASME installations.
