Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue.
I'll assume the thermostat is set higher than the pool temp and the system switch is ON. The first thing to try is to jump the TH & TH/PP terminals on the gas valve. This assumes you have a unit with a pilot that's lit all the time not electronic ignition. Tell me if the burner fires up when you jump the gas valve terminals
