We currently have a Sta-Rite 200BTU inground heater for a 14,000 gallon pool. Can we upgrade the heater to a Sta-Rite 333BTU without a lot of changes or additional time for installation? Also for the warranty to be valid, can we use a licensed heating and air company technician or do we have to go with a pool technician?

A     Answered on 6/17/2016 by InyoPools Product Specialist Scott W.

I'd need the length and the size of your gas lines. The owner's manual has a diagram on page 14 on what size gas lines you need for each size heater. Here's the link for the owner's manual.

I have ne of these for ten years and the exchanger is cracked well after ten years thats fine and I am sure it was a free at some point for this issue. Anyway, I want to purchase from your site as price is same everywhere join internet at $1999 but a local outfit out hear wants 3,250, are you kidding. I should be able to swap out the unit. And that is my question can you recommend an outfit out hear or is it simple. now mind ya I am quite capable and have hooked gas lines before, send email.

Hello Richard, We would recommend that the Max-E-Therm Heater 400000 BTU be installed by a licensed service technician. In the event you need to utilize the 1 year manufacturer's warranty, they may require receipt information of who it was installed by. We suggest you contact a local pool part/supply company that performs installations.

I am trying to hook the Max-E-Therm heater to a Jandy Aqualink controler. Need to know how to wire. Do I use 3 or 4 wire connection?

A     Answered on 10/2/2015 by InyoPools Product Specialist Lennox H.

Hi Bart, The Max-E-Therm Owner's Manual does not indicate a 4 wire connection so it will be the 3 wire connection.

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.
