    If you don't understand what you're working on then you shouldn't be working on it. The unit is shutting itself off because there are bigger issues with it.

    From what you have stated, I believe you are not qualified to be diagnosing a gas appliance that can put many people at risk.

    Do yourself a big favor and call a commercial contractor. Until they arrive, shut off the gas valve on the pipe outside the unit.
