75 gal, Model PR6 75... can't read rest of label
Ran perfect 5 Yrs
Power failure and Generator backup... now unit won't start... solid state ignition... no pilot button...

Red light on gas block is lit 'PR' label on it

Tried resetting the reset SWitch on the power vent hood, no go.
Tried unplugging for 20 minutes

No go

Any Idea?
