What are the steps to shutting down a gas furnace after the heating season while leaving the gas hot water heater on?
There's a red "Emergency Off" electrical switch connected to the furnace. Do I turn that off as well or is it connected to the hot water heater too?
I guess if I turn off that red "Emergency Off" switch & I no longer have hot water, then I'll know they're connected. Can I do any damage to the hot water heater if I do this?
