Hi. I have a Rheem Power Vent hot water heater, model PVW50-36FV, I was painting in the basement with little ventilation. The far right and left LED lights indicate the FV sensor detected the presence of flammable vapors. The unit is shut down and in lockout mode. How do I unlock this unit? Any help would be appreciated.

Contact RHEEM manufacturing for the correct answers. Last one I serviced was a real pain. In many cases the combustion air shutter slams shut not allowing the unit to fire off.

Follow reset procedures on the bottom of page 9... for flammable vapor lockout it truly works!
