Frequently Asked Questions
Which elevation version do I need?
Match the orifice to your site altitude. This #52 covers 6,000 to 8,999 ft, which suits mountain installations. The 017405 is the same size with a #51 orifice for 2,000 to 5,999 ft.
What happens if I install a sea level heater at 7,000 feet?
Thinner air means less oxygen for combustion. A sea level orifice runs rich at altitude, which costs output, sooties the heat exchanger, and can trip the unit out on a fault.
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?
Larger in-ground pools and pool and spa combinations. Mountain installations usually mean colder ambient temperatures, so size conservatively.
Is it natural gas or propane?
Natural gas. Fuel is set by model.
Does it need professional installation?
Yes. Gas sizing, venting, electrical, and altitude configuration make this a licensed installer job.
