Multi Fuel Chimney System
Twin Wall, Insulated Stainless Steel

The SMW Chimney Systems is a high quality prefabricated stainless steel insulated chimney system designed for solid and multi-fuel combustion equipment operating under natural draught and non-condensing conditions.

SMW is a prefabricated twin wall insulated chimney system and has been designed specifi cally to be used on solid, multi-fuel, gas and oil fi red combustion equipment, operating under negative natural draught conditions. Under no circumstances should SMW be used on appliances that generate
excessive condensation such as condensing appliances or where the chimney system
has been designed to operate under positive pressure conditions. For applications requiring
condensate and pressure resistance our Nova SM product should be used.
The SMW product is manufactured to the highest quality and is CE Marked to BS EN 1856-1, suitable for appliance with fl ue gas temperatures up to 450°C (550°C Intermittent).

The system consists of straight pipe lengths and associated fi ttings, which are constructed entirely from Austenitic stainless steel and have a 25mm insulated annulus. The external casing is weatherproof and supports the structural load, while the inner liner is manufactured from a high grade 316L stainless steel, offering excellent protection from the often corrosive products of combustion and is free to expand or contract as the fl ue gas temperatures change.
