Hayward H100ID1 Pool Heater - Rattles

I saw lots of posts on this model w.r.t. ignition problems...I have a different sort of problem. When ignition occurs the heater "knocks" - sounds like something loose flying around or a car with a faulty cylinder. Random sort of sounds. the entire heater shakes with each knock.

The heater does work like this...but makes me awfully nervous. Any ideas?

your heater does not have enough water running through it. Try cleaning filter first...
