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

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?
 Reply

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.

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.

what is difference between 266 and 267- I was looking PR267A but you show a 266 with different letters? I am concerned with the gas line length listed. I am replacing an existing heater, so gas is at heater location, but from gas source at house to pool is 80-100 feet, so how does this footage apply ? One last question, my pool is 18 x 40, is the 266/267 large enough ?
 Reply

A  Answered on 5/9/2015 by InyoPools Product Specialist Patrick P.

Hi Brad, The 266 & 267 would be the same heater, over the years this heater has been tested and at one point the testing agency rated it at 267,000 BTU's and then it was retested and rated at 266,000 BTU's the difference is negligible. Based on your measurements you would need a 1-1/4" gas line to adequately supply this heater. This 266,000 BTU heater would be a good choice for your 18' x 40' pool.

John, For your size pool, I would recommend a  336k btu or a 406k btu heater. Since you have a 266k btu installed, I would recommend checking with your gas company to see if your gas lines can support the additional btu size.

I have an existing in ground pool that we want to add a NG heater. Due to the location of the existing pump and filter near the house, we would need to install the heater approx. 30 feet away from the pump ad filter. Is there any potential problem with that?

Dean, As long as the pump is strong enough to provide enough water flow (gpm) to the heater and the gas line is sized correctly, you can install the heater 30ft away from the pump and filter. Please refer to the installation manual for space requirements.

hello I have a p-r266a-en-c install in my pool room already but I show the water electrical, and gas on the opposing side of the unit then the one on the picture shown. also can this unit withstand 30g pool and separate spa?

Hi. The water and electrical connections can be switch to either side, however, not the gas valve. This heater can be used to heat a pool and a seperate spa. I will need you to reconfirm the pool and spa surface area.

We had this raypac unit installed in May this year. It just recently started making a harmonics sound while running. What to do?

I'm not clear on what a harmonic sound is, but the heater may need to be cleaned. I suggest contacting Raypak for a troubleshoot, they can be reached at (805) 278-5300.

I received the heater from you (Raypak Heater 266,000 BTU NG – P-R266A-EN-C). No shipping problems. It is the same model I had before, and everything looks identical to my old heater except for the wires. The previous model had 6 wires (not 4). So I have two extra wires going into the heater, which have no connections in the heater. Can you tell me why? Is it something that was added previously by the installer? For what purpose?

Hi, Eyal. 1. The heater still has an optional fireman switch. Found it on the diagram.2. The two extra incoming wires I had (from the pump electrical box) were wired for the fireman switch...

I had an old model of Raypak Heater 266,000 BTU NG – P-R266A-EN-C. Got from you a new one. No problems. However, according to the OLD manual of the model, there was an option for adding a "fireman switch". It is shown in the wiring diagram of the same heater I bought 12 years ago. I am looking at the NEW manual and don't seem to find anything about wiring a "fireman switch". I just want to verify that this is the case (no firing switch option).

A  Answered on 1/7/2020 by InyoPools Product Specialist Matt S.

Unfortunately, we do not have a dimensions sheet on the 265B, but this is the spec sheet on the PR266AENC RP Series Technical Data. That pdf lists all the cabinet dimensions you wish to compare to your current unit.You should also be aware, this unit is rated for residential only use, whereas your C265B is a commercial unit. If this heater is for commercial use, you will need the Raypak Heater 266BTU NG ELE ASME.

hello, i was told i need 120K BTU for my pool does it make sense for me to purchase your 266K BTU ? will that be overkill? thanks very much sol
 Reply

A  Answered on 2/4/2020 by InyoPools Product Specialist Eric J.

Hello, The general rule of thumb when it comes to sizing a pool heater is a pool over 15k gallons would require 140k BTUs. It would depend on how big your pool is to determine if the 266k is overkill.

My heater makes a loud banging sound every so often after the pool pump has shut down. It sounds as though its trying to fire up. Our pump runs an 8 hour cycle. Its 3 years old and works perfectly otherwise. How can I correct this?

A  Answered on 3/17/2020 by InyoPools Product Specialist Lennox H.

Hi, Gary. To resolve this issue, the tube bundle will have to cool down prior to the pump shutting down. Installing a Fireman Heater Switch - 156T4042A if you have mechanical timer will help and allow your tube bundle to last longer.

My pool heater won't heat, it goes thru cycle and when it's get to SPK on screen it stays there and never heats up the heater?? Any suggestions?
 Reply

A  Answered on 5/7/2020 by InyoPools Product Specialist Alex V.

Mike, When you are seeing SPK, check to see if the pilot is lighting. If the pilot is lit, it should begin a sequence that would signal the PC board to open the main gas valve and fire the burners. Said signal is a DC signal and could be interrupted by a loose or disconnected ground wire, chewed or bare wire leading from the gas valve up to the PC board, or a loose connection at the PC board. Also, inspect the condition of the pilot itself. Excessive corrosion on the pilot could also interfere with the proving signal. If the pilot is not lit by the spark, then turn off the gas and clean the pilot and pilot tube.Also, check for any loose wires/crimps in the wire harness. Also, check the wired going into the connector that plugs into the PC Board. Sounds as if it could be momentarily losing contact.

Hi Rick, This would be the replacement for your heater if the BTU's were similar (i.e. your BTU's are between 250K & 275K). The headers on this heater can be reversed to come in the left. Here is a Video on How to Reverse the Water Connections on a Raypak Pool Heater showing how this is done. In regards to the transformer I'm not aware of a transformer needed on this heater you may want to get more details from your pool guy on this.

We would recommend this RP2100 Digital Heater - R406A - Copper - Natural Gas - P-R406A-EN-C #50 rather than the R266A heater, as the heat output of the R266A is not nearly as much as the R406A.

A  Answered on 12/27/2021 by InyoPools Product Specialist Rich N.

Hi Kathy - you can either "tell" the heater to go to Spa mode at the control panel or wire up a remote per page 36 of the manual.  The remote can be as simple as a flow switch if you have separate, dedicated pressure lines to your spa and pool. Be sure to activate the remote input (also on page 36) if you choose that route.

Does Raypak make the 266k btu heater with the water supply/discharge on the left side vs. the right? Left side discharge will make it easier to swap out.

Hi John, the supply/discharge ports for this Raypak heater are easily changed from one side to the other by removing the side panels and switching the headers from one side to the other.  See page 25 of the manual for instructions on how to do it.
