Why did I get a high limit 2 fault?
It was not a particularly hot day and water flow was about as strong as it gets (no blockages and freshly cleaned filter). After the first fault, I left the heater off for about 30 min with the pump running, then turned it back on. It fired up fine, ran for a few hours and then I got another high limit 2 fault.

How to check high limit fault in Raypak?
I would start by removing the Hi Limit 2 from the header (should be yellow wires) and let it hang by the wires, and see if you still get the fault. If you do, remove the other high limit (black wires) and plug it into the yellow wires, and the other hi limit into the black wires (switching them). Let them both hang and check.
What should I do if my hi limit is not working?
A Hi Limit that is operating properly will: Detect high heat, open, shutting the heater down, cool, close, and heater should try to relight. If it is shutting down and not relighting after a few moments, then there may be a problem with the hi limit itself hanging open.

Can a mangled gasket cause a fault?
If this is the case, look towards limed tubes (improper water chemistry), sooting (gas delivery) or a uni-therm gov. (improper mixing). I don’t think the mangled gasket would cause this type of problem.
