Water Connection
On units equipped with an optional water fill valve connect a water line (minimum 1/4") to the valve with a 1/4" NPT female fitting.
Units with dual (hot and cold) valves must have the hot water line connected to side with the hot water valve (red) and cold water
line to the cold water valve (blue). Plastic or rubber hose is not recommended, as it may melt against the hot kettle side.
