Ideal Front Cover Plate Gasket Super Plus 013771

The Ideal 013771 is a front cover plate gasket for Ideal Commercial boilers in the Super Plus family. It sits between the front cover plate and the main heat exchanger or combustion chamber face, sealing the joint against flue gas and water leakage once the plate is bolted down. It is a service item: the gasket is normally renewed whenever the front cover plate is removed for inspection, cleaning or component replacement.

• Visible water or flue gas staining around the front cover plate joint.
• The gasket is compressed, brittle, cracked or stuck to the plate face on removal.
• The cover plate has been disturbed for cleaning or component access and the old gasket will not reseal.
• Combustion readings drift or the joint weeps after the plate is refitted.
• The gasket surface shows flattening or delamination where it contacts the sealing face.

• Confirm the boiler model and GC number against the compatibility list, as the Super Plus range uses several cover plate variants.
• Check the existing gasket or the appliance data badge for the number 013771 or the cross-reference 1170546.
• Inspect the cover plate face for pitting or distortion before fitting a new gasket, as a damaged face will not seal.
