Water heater switch
Is the outside switch on the water heater only for the propane ignition, or does it control the electric as well? I have inside switches for each of these.

The outside switch is ONLY for 120. It is usually a winterizing switch. Turn it OFF when you drain the W/H to prevent dry firing when it is empty. If you have an inside switch, the outside switch must be ON for the inside switch to work. Doug
