Have you ever seen what’s up that hole above the burner?
I don’t have one handy, but digital cameras are great for sticking into little places that my head won’t go.
They usually contain baffles (except for some 50 gal, 2007 bld A.O. models HA!).
These units should be serviced and cleaned, if necessary, every year!
Can’t enlarge these shots for some reason.
I don’t know how it works on my computer, but I just one-click the small picture, and a new large picture appears in window. …
