Question about Pool & Spa
There are many things that will prevent a heater from firing. Best to get a pool tech out to see what happened. Heaters should only be worked on by people trained on them, as they are extremely hazardous if firing in any manner other than designed.

Yes! It is dangerous. The pressure switch is malfunctioning and allowing the heater to remain on when the pump shuts off. You should not use the unit until a qualified repair tech can look at the unit. There is only one other set of limit switches that are turning your burners off before the boiling water bursts the tube bundle so if they fail to react in time, you'll burst the heater, cause expensive damage and risk injury.

Actually, the clicking is likely causing the shaking. Inside the manifold of a H100 is a stainless steel diverter plate that send some of the passing water into the heat exchanger and lets the rest past and back to the pool. When it breaks, you will hear a 'clicking' noise at it rattles in the water path. When it breaks, the flow to the heat exchanger is intermittent and you will begin to boil the water, causing the shaking. This situation is dangerous, especially without a pressure relief in the heater or pipe. As long as your water chemistry is sound, Hayward will usually cover this under warranty even if the unit is over a year old.

SOURCE: pool heater won't light
it is possible to light a pool heater with an ignition device,however it is not advisable.since your unit is calling for heat and the gas valve is opening,i suspect you have a faulty ignitor

This sounds like you have a problem with your pilot. You can check this with a small mirror to see if their is a spark when you turn it on. If you have any soot build up on the pilot that will stop the spark and keep it from lighting also. If you have a short on your pilot wire this could be the problem also. I hope this helps, good luck.
