Go to the Girard website and figure out if you have a Gen 1, 2 or 3 model. If it's a Gen2, then yes - inside, upper left and towards the back is a round white cylinder (about the diameter of a nickel). There is a tiny, black reset button on the middle of that cylinder.
Pressing it restores the gas ignition on my Gen 2.
Once, I had to flip the red On/Off switch to off before it would restart,
There's *one* Youtube video out there where the fellow shows you how to do it too.
