Frequently Asked Questions
Which elevation version do I need?
Match the orifice to your site altitude. The #50 covers 0 to 1,999 ft, this #51 covers 2,000 to 5,999 ft, and the #52 covers 6,000 to 8,999 ft. In this 266A size that is 017400, 017404, and 017408 respectively.
What happens if I install the wrong elevation version?
The heater runs rich, loses output, sooties the exchanger, and can fault out. It is not a field adjustment you should improvise, so order the right orifice.
Why choose cupro-nickel over copper?
Cupro-nickel resists corrosion far better in saltwater pools, low pH water, and high flow installations. On balanced chlorinated water, copper costs less and performs the same.
What size pool does 266,000 BTU suit?
Mid-size 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.
Is it natural gas or propane?
Natural gas. Fuel is set by model.
Does it need professional installation?
Yes. Gas sizing, venting, electrical, and local code make this a licensed installer job.
