Gas valve might be bad... The honeywell gas valve for atmospheric models is generic and can be replace without removing from heater.

try unplugging the power to the unit it should rest it

Some time ago I had that happen and because of the age my repair man said it would cost too much to repair it. The problem was a worn out thermostat.

This is likely a gas valve issue. Call a repair person, it is not recommend you repair it as there is a danger of explosion.

More than likely the gas valve is defective.

No, the the defective valve is only on gas fireplaces and stoves, not hot water heaters.

Check the pilot is clean not a short flame so its missing the sensor. Also check flame sensor and connection .

Google for "Vr8204c 1084 manual" ... 1st item says: http://www.warming-trends.com/manuals/HoneywellTroubleshootingGuide.pdf 68-0047 - VR8204; VR4204 Intermittent Pilot Dual Automatic Valve Combination Gas Controls Pretty much chapter and verse - you don't usually get any more.XV66OI This is an industrial valve. Are you safe to meddle with it?

being gas and you are not a qualified gas fitter, the sensible thing to do is to get a gas fitter in to adjust /fix the unit of course the unsafe thing to do is to try and do it yourself
