Frequently Asked Questions
Do I need both ASME and Low NOx?
They answer different requirements. ASME is a pressure vessel standard demanded by commercial and municipal code. Low NOx is an emissions standard demanded by air quality districts. A commercial pool in California typically needs both, which is what this model covers.
What is the difference between the 406A and the 407A?
The 407A is the Low NOx version of the same size class, rated 399,000 BTU.
Why bronze headers?
Bronze holds up better than standard header materials under continuous commercial duty and aggressive water chemistry, which is why commercial specs call for it.
What elevation does the #26 orifice cover?
0 to 5,000 ft, a wider band than the standard configurations. Above 5,000 ft, ask us before ordering.
Can I use this on a residential pool?
Yes, but you are paying for ASME certification you likely do not need. A residential Low NOx 407A is the better value unless local code says otherwise.
Does it need professional installation?
Yes, and commercial installations typically require permitting and inspection in addition to a licensed installer.
