Frequently Asked Questions
Why is the 406A rated 399,000 BTU?
The 406A chassis is rated 406,000 BTU on natural gas. On propane the certified input is 399,000 BTU. It is the same heater size, not a smaller model.
What is a millivolt heater?
A standing pilot flame heats a thermocouple, which generates the small voltage that operates the gas valve. The heater needs no household power at all.
Why choose millivolt over electronic ignition?
It keeps working through a power outage, and it can go on a remote pad with no electrical run, which saves trenching power out to the equipment. The tradeoff is that the pilot burns gas continuously and can blow out in high wind.
Is the 009203 propane or natural gas?
Liquid propane. Order 009195 for the 406K natural gas millivolt version.
What size pool does this suit?
Large 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.
Does it need professional installation?
Yes. Propane sizing matters especially at this output, since an undersized supply will starve the heater.
