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.

My LXI for my salt water pool and spa turns on and you can hear it try to ignite and smell the natural gas but will not light. I made sure lines were clear good air and water flow to the best of my knowledge. It will not lignite and it says not to use a lighter for the pilot any suggestions? Thank you

Sounds like it is either the flame sensor or the ignitor. I recommend giving Jandy a call to see if they can pinpoint which part you need. Their number is 800-822-7933.

Is the lxi a better option for a salt house after pool

A  Answered on 5/10/2018 by InyoPools Product Specialist Lennox H.

Hi, Eric. The LXI Series heater has a copper heat exchanger which is not the best option for a saltwater pool. You will need a heater with a cupro-nickel exchanger.
