Can you use an electrical cord and plug for an exterior tankless gas water heater?

Tuesday, May 23, 2023

Although a cord and plug is supplied by many manufacturers for an interior gas tankless water heater, an exterior cord is not allowed. The required 120-volt electrical must be hard-wired. Here’s the page from Rheem manual with their requirements. Also, a dedicated circuit is recommended and the circuit should not be GFCI or AFCI protected.
