Hello and happy swim season to all! 
I started up my heater yesterday and things seemed to be going well for a few hours however, once it got to 79* F,  it started making a strange “clattering” sound then shutting down. After a couple of seconds, you can hear it re-ignite and the same thing happens over and over. Does anyone have an idea what could be happening? I would very much appreciate feedback! 
Thanks in advance!!

For gas units it is best practice to consult a technician or call the manufacturer of the unit.
