Frequently Asked Questions
Which elevation version do I need?
Match the orifice to your site altitude. This #51 covers 2,000 to 5,999 ft. The 017410 is the same size with a #52 orifice for 6,000 to 8,999 ft.
What happens if I install the wrong elevation version?
The heater runs rich, loses output, sooties the heat exchanger, and can fault out. Order the orifice that matches your altitude rather than adjusting in the field.
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 this suit?
Large in-ground pools and pool and spa combinations where recovery time matters. 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 matters especially at this output, since an undersized supply line will starve the heater.
