Water heater blower needs re-wire
I have Rheem gas water heater with blower, that was plugged into the standard AC socket that is mounted into the top of the heater tank casing.
One morning the water was cold. I reset the breaker and the water heated nicely. A couple days later I had blower plug/socket melt violently! Luckily nothing caught fire. (I guess the breaker was trying to tell me something).
I cut the wire out of the thermostat that feeds this plug and capped it. I plugged the blower into a normal wall outlet, and turned the breaker and water heater back on. All is running just fine now, but the blower is on continuously, plugged into the wall.
My question is, how to wire the blower properly into the thermostat. The old wire that I capped is threaded through the housing of the heater, and I expect that going route to not be an option. I could easily have a wire coming out of the heater's electrical box around to the blower, but I want to do this right. Do I need to drill a hole in the this electrical box and put in a shielded conduit back up at the blower (mounted plug box at end)? This would seem like an electrically safe approach, but I was hoping there was be something easier. There is already a conduit into the box that is providing the power. I could try putting the wire up that conduit to the nearby junction box, and tapping into that box for the plug.
Has anyone had this type of thing happen before? I'm the previous short was at the plug due to conductive stuff somehow collecting, or the wire shorted along the tank wall.
