Question about Raypak 2100 Pool Heater Propane 206000 BTU' (Pilot) ()

Open Question

I have a rp2100 pool heater. I just installed a new Pilot burner, as the old one finally quit. It works, the heating elements light and burn, but I noticed that a flame continues to burn at the new Pilot burner. I don't remember seeing this before . I thought it would spark, light the heating elements and then turn off. Should there be a flame still coming out of pilot after the heater lights?

Part of your fire tile (white like) has fallen into your pilot area and is messing with the gas/air mix. Cleaning it out should clear the pilot and have it return to a nice blue flame. If you can get a look inside the unit from a mirror to be sure the area of tile damage is minimal you should be ok. Of course to be on the same side you may want to call in a heater tech to tear it down and be sure the fire box is still sound.

It is probably something much more simple than that...Turn it on and stand back until it finally ignites, then look, using a mirror, at the burner tray from below. You will probably find a lot of the tubes, especially those near the pilot area, are not working or are burning bright orange. If that is the case, something, probably spiders, are blocking the gas from getting into the tubes. That will cause the big burst at ignition as the gas builds up for a bit before it finally reaches the pilot area.

Hello my name is Heath it will be my pleasure to assist you. Find the rollout switch and on the back there is a small red button if you push the button in it will reset the switch. The rollout is usually located near the burner section of the heater.I will attach a picture of a rollout switch which shows the small red button.11c0d2e.jpg

I am thinking it could be the relay. The relay directs the power to the device. In most devices it is the one that makes the 'clicking' sound.

It sounds like an issue of either incorrect gas valve settings, or a case where the refractory kit has started chipping off on the flame bed.

Heres what you need to find out. Can your service tech tell you what the pressure is before and after the regulator?

On natural gas it should be before the gas valve at 7-14 inches of water colum.
After the gas valve should be 4 inches water colum.

For propane it should be between 12-14 inches water colum before the gas valve and 10.5 inches water colum after the gas valve.

If you tech cannot verify any of this, you need a new tech. This should have been the first thing to be looked at.

Note: The most common cause for flame rollout (which is what you describe) is the refractory kit chipping and cracking . Then peices fall onto the burner tray and cause the high flame condition that you mentioned. If the tech working the job has not checked before and after gas pressures, and cleaned and inspected the burner tray and the heat exchanger. Fire him. These are all the quick easy things that would get you down to the bottom of your current situation. I wish I could go more in depth with troubleshooting, but it is difficult on these forums.

My raypack heater cycles on and off with a big bang each time it tuns on


It may be due to gas "pooling" before it ignites. Check that the pilot assembly is correctly positioned, and the burners and heat exchanger are clear of soot and debris.

Pilot lights but burner won't light. Display continues to read SPK


On these units, the pilot ignitor and the pilot rectefier are the same part. The pilot can be lit, but not be sensed by the rectefier/ignitor. This will keep your burner tray from igniting. You need to replace the ignitor assembley. If it is the same as the raypak digital 406a I charge about $75 for that part, and it takes about 20 minutes to install. Need the part or more help e-mail me. [email protected]

RP2100 GOES ON AND OFF REPEATEDLY


If you received the PRS error, then it is the water pressure switch. The water pressure switch, or heater actuator, ensures
that the heater operates only when the filter pump is in
operation. It is located on the inlet/outlet header. It is
factory set at 1.75 PSI for deck-level installations.
When the heater is located below the level of the spa
or pool, it may be necessary to adjust the pressure
switch to compensate for the no-flow static head. If it
is necessary to adjust the water pressure switch, Follow the directions in your manual.If your is the low Nox model, then you have a combustion fan. This has a fan air pressure switch but the error code for it is FAN I believe. If you don't have a manual you can get one at www.raypak.com

Pool heater


This is an old, but good heater. Power is either stopping thru the safety loop, high limits or pressure switch, or the pilot generator is tiring out and not sending enough power to keep the gas valve open.

I have a Raypac C155A LP spa heater. won't light


I would agree with you. The pilot generator has probably degraded over the years and is only proving enough millivolts to power the pilot but not enough to run the gas valve for your main burners.

Replacing the pilot generator, preferably the entire pilot assembly, will fix the problem.
