Heatline Gas Isolation Valve 0020197015

The Heatline Gas Isolation Valve, part number 0020197015, is a service valve fitted to the gas inlet of Heatline Capriz 2 and Monza 2 combi boilers. It allows the gas supply to the appliance to be isolated for servicing, safety checks and component replacement. The valve is operated by a screwdriver slot or lever, depending on the installation, and sits between the incoming gas supply and the boiler gas train.

• The valve spindle is stiff, seized or will not turn through its full travel
• Gas is smelled or detected at the spindle or valve body during a tightness test
• The valve will not fully isolate the supply, so the boiler cannot be safely worked on
• Corrosion, staining or weep marks are visible around the valve body or its connections

• Confirm the boiler model against the fit list above, as the valve is listed for Capriz 2 and Monza 2 appliances only
• Check the existing valve's connection type and thread against the new part before removing the old one
• Confirm the isolation valve is the faulty component and not the adjoining gas pipework or boiler gas train
• Gas work must be carried out by a Gas Safe registered engineer
