Designation for an AFT heater using natural gas is “EN”.
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-R407A-EN-X
= Plastic headers, 407 model size, AFT, natural gas, cupro-nickel.
For altitudes above 5,000 ft., consult the factory.
For Canada, no de-rating is required for elevations up to 4500 ft.
Plastic (polymer) headers cannot be used for ASME installations.
*Note: For outdoor stack, use J dimension in the table above for appropriate size PLUS six (6) inches.
