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. Check with your local air district before ordering.
What is the difference between the 336A and the 337A?
The 337A is the Low NOx version of the same size class. The output is 332,500 BTU rather than 336,000, which is the small tradeoff for the cleaner burn.
Why bronze headers?
Bronze resists corrosion and holds up better than standard header materials under demanding service and aggressive water chemistry.
What size pool does this 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 are the other sizes in the Low NOx line?
The 207A is roughly 199,500 BTU, the 267A is 266,000, this 337A is 332,500, and the 407A is 399,000.
Does it need professional installation?
Yes. Gas sizing, venting, electrical, and local code make this a licensed installer job.
