This pack includes the stove connection (support block and 175-200mm stainless steel increaser adaptor for a 175mm stove pipe) and 8.4m of 180mm flue up to the underside of the capping.

The capping, chimney pot, top ring and raincap are not in the pack. Choose a capping for render or brickwork on this page, then either a 200mm chimney pot or the DM44 raincap and top ring.

If your stove has a 150mm outlet, the adaptor can be upgraded to the 150-200mm increaser adaptor on this page.

The Isokern Double Module DM44 180mm i/d chimney pack contains the pumice blocks and fixings to build a 8.4 metre high DM44 chimney with a 180mm internal diameter flue. The Isokern DM44 system is a self-supporting pumice block chimney: each 440mm square casing (300mm high) holds a round 180mm flue block, and the casings and flue blocks are bonded with Isokern Lip Glue. A half-height starter flue block goes at the bottom so the flue and casing joints are staggered.

This is a stove pack. It includes the DM44 180mm support block, which sits on lintels or a concrete slab over the stove recess, and a 175-200mm stainless steel increaser adaptor that connects a 175mm stove pipe to the flue. If your stove has a 150mm outlet, you can change it to the 150-200mm increaser adaptor using the option on this page.

Lip Glue quantity is worked out from the Schiedel joints-per-bag chart (DM44: 5 casing joints per bag).

Not included: the chimney capping and the chimney termination. Choose your capping on this page: 130723 DM44 Capping for Render 570mm Square, or 130724 DM44 Capping for Brickwork 820mm Square with 130728 DM44 650mm Square Corbel. Then choose your termination as an option: a 200mm terracotta or buff chimney pot (127341 / 130697) or the DM44 Raincap & Top Ring. A chimney pot needs 38mm clearance to combustibles and is set into the capping and flaunched; a raincap and top ring on a straight rendered stack allows 0mm.

Extras such as offsets, flue entry kits, access blocks, wall ties and lintels can also be added on this page.

For an 8.4m flue this pack builds 28 courses: 28 casings (440mm square, each 300mm high) around 28 180mm flue blocks (28 x 300mm = 8.4m), plus the starter block and 8 bags of Lip Glue. It suits a DM44 chimney that needs 8.4m of 180mm flue from the support block over the stove to the underside of the capping.
