Potterton Flue Cover Insulation 11 Section 17070909

This is a flue cover insulation component manufactured by Potterton, supplied in an 11-section format. It forms part of the flue assembly on the Potterton Derwent Prestige PLUS boiler, where it provides thermal insulation around the flue cover. Its role is to limit heat loss from the flue path and protect surrounding components from sustained heat exposure.

• Visible cracking, crumbling or breakdown of the insulation material
• Discolouration or scorching indicating prolonged heat exposure
• Insulation sections loose, displaced or no longer seated on the flue cover
• Heat damage or condensation marking on nearby components in the flue area
• Insulation missing sections, leaving part of the flue cover exposed

• Confirm your appliance is a Potterton Derwent Prestige PLUS
• Check the existing insulation is the 11-section type before ordering
• Inspect the flue cover itself for damage, as the insulation alone may not resolve a deteriorated cover
• Verify the part against the manufacturer's parts list for your model
