Water heater question
My new coach has an Atwood 6 gallon tank type water heater with both gas and electric heat. It works fine but when on gas I’ve noticed something outside of my experience. It lights and burns fine but all the while the burner is going the igniter continues to spark. Not rapidly like when lighting the burner but just twice about every three seconds. Click, click pause and repeat. I see no purpose in it and am concerned it will burn out the igniter. On the other hand it is a distinctly different mode from start up so seems intentional. Is this a normal?
Thanks friends.
