Atwood GC6A 6-Gallon Gas/Electric Water Heater Illustrated Parts
GC6A combines the pilot-operated propane heater with electric heating. Its original service layout separates the gas and tank assembly from a short electric-element reference. The electric section identifies an older bolt-on style, which differs from screw-in element designs.
