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.

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.

Can you get a remote control for the Raypak 266000?

A  Answered on 1/6/2015 by InyoPools Product Specialist Robert M.

Hello Suljo - You could use something like the Intermatic PE653RC to remotely control the Raypak heater.

Hi, I wondered how high I can turn up the heat on the Raypak 266? My last heater, a Hayward, only went up to 90, and I don't believe the actual water temp ever got near that. Hopefully, I won't need to turn it so high, but there are always a few cool evenings when I like to crank it up. Thanks.

A  Answered on 4/2/2015 by InyoPools Product Specialist Lennox H.

Therese, these units are factory set for a max temperature of 104 degrees. A licence contractor can adjust it to 107 degrees max following Raypak instructions.

Is this heater available above 2,000 feet?

A  Answered on 5/1/2015 by InyoPools Product Specialist Patrick P.

This particular model is good for 0' - 1,999' we do have our Raypak High Altitude Heaters which go from 2,000' - 9,000' so I would suggest the high altitude model.

After nearly 20 years of reliable service my old RP2100 gave up

Written on 7/4/2019 by Guest

Disconnect gas, electric, and pvc water pipes.

Remove old heater

Clean area

Position new heater.

Reconnect services. Note: Electrical connection was same. Had to install new water in/out piping due to cutting out old piping.

Startup according to instructions

You will need help removing old and positioning new heater. They are heavy.

As for services, I was lucky in that I had to do little fabrication. This heater was very similar to my old one. Make sure to confirm location of all connection.

This is NOT a difficult task IF you are comfortable working with gas, electricity, and PVC plastic pipe.
