• Fit a stop valve and suitable fitting on a cold water line (e.g., 3/4” x 1/2” 311 or washing machine type stop valve).
• Use a food-grade inlet hose with a 3/4” BSP female elbow fitting to attach to the boiler's underside.
• Ensure that the pre-attached sealing washer is fitted on both ends of the hose.
• Flush the water line and inlet hose by turning on the water and allowing several gallons to flow through to remove impurities and dust.
• Connect the right-angled tailpiece of the hose to the boiler’s inlet valve (3/4” BSP), ensuring the sealing washer is fitted here as well.
• Turn on the water and check for leaks.

NOTE: Avoid using a non-food-grade hose (e.g., a washing machine hose) as it may cause off-tastes, smells, and potential toxicity in the water.
