Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your

issue. First I’ll need some more info so I have a more complete picture of your situation.

What's the brand and model number of your unit? Do you have any vapors flammable or otherwise in the area? or did the heater get wet?

Rheem water heater XG50T12DM40U0, no vapors, other than painting wall, no wetness or leaks notice
HVAC Technician: Rick, HVAC Supervisor replied 5 months ago

Painting produces vapors. You first need to clear the air so there is no odor at all in the area. Do you have an ohm meter?
