Do you know where I can get a conversion kit going from natural gas to LP for an H2501 heater? I have been looking bit have had no luck locating one.

A  Answered on 4/23/2020 by InyoPools Product Specialist Patrick P.

You will need a HAXCNK0001 but unfortunately, this conversion kit has been discontinued by the manufacturer. I beleive you can purchase these parts individually here on the Hayward H Series Parts Page

What is the difference between an Electronic and Millivolt ignition?

A  Answered on 10/10/2012 by InyoPools Product Specialist Patrick P.

The basic answer is that Millivolt is the old style of ignition, using a standing pilot light. While the electronic ignition uses a spark start system like a gas grill. Electronic ignitions are more efficient in gas usage and also are better suited for high wind areas where a pilot light might get extinguished.

Will a gas heater operate at the low speed of a dual speed motor?

A  Answered on 1/16/2012 by InyoPools Product Specialist Patrick P.

Probably not - Most gas heater will shut off at low GPM levels (20-40) to keep the heater cores from overheating - 20 for 200 BTUs, 40 for 400 BTUs. Depending on your pool system you might get these GPM levels at the low speed but generally these heaters must be run at the motor's high speed.
