The Shieldmaster single to twin wall adaptor is the first twin wall flue part you will need for your twin wall flue installation. It connects directly to your stove spigot and then upwards to your twin wall pipes or to the length of enamelled pipe coming out of the top of your stove. For best results, it is generally recommended to begin with a section of enamel pipe straight from the stove, as this option is both more cost-effective and more durable.

Installation Notes

This product does not come with a locking band, as the next part you attach it to comes with a locking band. Attach the bottom of this product to your stove pipe or spigot with fire cement and the top connects directly to your twin wall pipes.

Important Information

All twin wall flue parts are measured by their internal diameter. Due to the insulated construction, the external diameter will be approximately 2 inches larger than the stated size.

Technical Guidance

For help with installation requirements and compliance, please see our Technical Information section, which includes easy-to-understand guides covering Building Regulations for stove and flue installations.

Shieldmaster twin wall flue pipe is precision made to achieve a smaller distance to combustible materials than many other pipes on the market.

With its unique push fit system it easily locks with an included band without the need for any sealant or adhesives at the joins.

Warranty Details

Shieldmaster flue products come with a 25-year warranty covering manufacturing defects, provided the system is installed and used in accordance with the supplied installation instructions. To maintain warranty validity, the flue must be professionally swept at least once a year by an approved chimney sweep, with a signed service record kept. When burning solid fuels, only those approved by HETAS or the Solid Fuel Association are permitted. Use of unapproved fuels or any indication of a chimney fire will void the warranty. For coloured flue pipes with a powder-coated finish, the surface coating is covered by a separate 2-year warranty.
