Guessing you have a milivolt heater. While your pilot will light when you push the pilot light button down you need to generate 200mv to open the selenoid for the pilot and another 300mv for the main valve. This can be checked by removeing the leads from the pilot generator (wires from the pilot), Push the pilot button down and hold in place (a small screwdriver wedged in becide the button will do this) Then check the milivolt reading from the generator. This reading should be between 500 and 700mv (1/2 to 3/4 of a volt) If you don't have this your pilot generator is bad.
If you do then you need to hook the leads back up to the valve and unhook the saftey circut leads and try to light the pilot again. If the pilot still won't light your gas valve is bad. If it does then you have a problem in your saftey circut and you will need to check each item in the circut by removing and jumping past.
This would be more in line with just the main side of the valve not opening. So I'm sure you will find it to be the pilot generator or the valve being bad. As I stated before this system only runs on 1/2 a volt so all connections need to be clean and tight also. Could be other problems but this should cover the common reasons. Good luck.

Thank you for posting your question here on

Replacing the roll out switch is an easy do-it-yourself repair. Fixing the problem causing the roll out of the burner flames in the first place is a bit more of a pro job. Something is causing to much heat to roll out the the combustion chamber into the control area causing the switch to fail. You will continue to burn the link until the underlying problem is fixed.

If this answer does not fix your problem, please comment with additional details prior to rating the answer. Positive feedback is appreciated once your problem is solved!

Yes, when you pull the headers off the exchanger they just go on each pipe and then bolt the headers back on.

What does CFH means on my control board?

"call for heat", in other words the heater realizes the water temperature is below the set-point on the heater and therefore wants to turn on and heat the water.

My boiler keeps running even with thermostat removed from circuit. It is a Raypak H1-133A thermionic heating system (pipes in the floor) about 15-20 years old. (thermostat is original, 50 years old).

I answered you previously with information that didn't help. I'm not answering for the $5, but to try to help you. It's been several days and I assume Raypak is not helping.
Possibly the thermostat closes a relay that is on the main control board, maybe this relay is stuck closed. Can you follow the wiring from the stat to the controller? Something in the controller is thinking you need heat.

"CLK" is being displayed on my Raypak making it impossible to put my heater on to heat my pool.

CLK stands for Clock. Your heater thinks it is connected to a timeclock and the circuit is open. The connection is on the back of the circuit board, and a communication wire will continue on to your timeclock or controller. Close that circuit and it should fire.

Raypak pool heater piliot light on heat will not turn on

Make sure that gas control knob is set to ON (counterclockwise). Make sure that ON/OFF switch is ON. Check that temperature setting is high enough to call for heat. Make sure pool pump is running and water is flowing to unit.
If not above there is a diagnostic procedure on page 33 of manual at:
