Frequently Asked Questions
Do I need a Low NOx heater?
If you are in California, Texas, or another regulated air quality district, yes. Many jurisdictions will not permit a standard heater.
Why the bronze and cupro-nickel combination?
This is the durability build. Bronze headers resist corrosion at the water connections and cupro-nickel tubes resist the pitting that copper suffers in salt, low pH, and heavy use conditions.
How does this differ from the 017708?
Same 407A Low NOx size. The 017708 is ASME certified with a copper exchanger, which commercial and municipal installations usually require. This one is the cupro-nickel build for demanding water chemistry.
What size pool does 399,000 BTU suit?
Large in-ground pools and pool and spa combinations where recovery time matters. Sizing depends on surface area, temperature rise, and climate.
Is this the largest Low NOx model?
Yes. The line runs 207A at 199,500 BTU, 267A at 266,000, 337A at 332,500, and this 407A at 399,000.
Does it need professional installation?
Yes. Gas sizing matters especially at this output, since an undersized supply line will starve the heater.
