Saunier Duval Insulation 0020183143

This is a Saunier Duval insulation component, identified by part number 0020183143 and supplied under the product name SAUN 0020183143 INSULATION. It is a service part for Saunier Duval heating appliances, used to insulate a specific internal location within the appliance. Fit it only where the manufacturer's parts breakdown for the appliance specifies this part number.

• Confirm 0020183143 against the parts list for your appliance model and, where applicable, its serial number range, as insulation part numbers change between build variants.
• Check the position the insulation sits in — insulation is often used at more than one point in the same appliance, and the same appliance can list different insulation part numbers for different locations.
• Inspect the existing insulation for contamination, moisture, brittleness or breakdown before ordering, as damaged insulation in the wrong place can affect combustion, heat retention or air paths.
• Check whether the insulation is supplied with any retaining clips, gaskets or seals as part of the appliance assembly, and order those separately if they are also required.
