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 017707?
Same 337A Low NOx size with bronze headers. The 017707 uses a copper heat exchanger. This one uses cupro-nickel, which is the better choice for saltwater pools.
What size pool does 332,500 BTU suit?
Larger in-ground pools and pool and spa combinations. Sizing depends on surface area, temperature rise, and climate, so have a pool professional size it for your install.
What elevation does it cover?
0 to 5,000 ft. Above that, ask us before ordering.
Does it need professional installation?
Yes. Gas sizing, venting, electrical, and local code make this a licensed installer job.
