Raypak ASME Natural Gas Commercial Swimming Pool Heater, 406k BTU, 2000-6000 Ft, B-R406A-EN-X #51, 017406

Some local codes require that public pools, pools that are in a condominium and apartment or other commercial application be ASME certified.

ASME stands for American Society of Mechanical Engineers. They are a non-profit group which sets many industrial and manufacturing standards. A pool heater that is made to ASME standards will perform to a set of specifications as determined by ASME, specifically in relation to the operating water pressure the appliance can handle.

Each and every ASME heat exchanger that goes into a Raypak heater is certified by a state inspector to make sure it complies with the ASME code for that particular product.
