150MM PRIMA PLUS 1MM WALL SUPPORT Prima Plus is a high quality 316L stainless steel single wall flue system with a wall thickness of 0.6mm. It is designed for use on gas and oil burning stoves and boilers with continuous operating temperatures up to 450°C and short firing up to 600°C. With the addition of a gasket to the joint, Prima Plus is designed for fluing condensing gas and oil appliances with positive pressures up to 200Pa, continuous operating temperatures up to 160°C and short firing up to 200°C. It can also be used for lining brick stacks for gas, oil, multi-fuel appliances and open fires as an alternative to flexible liner. (The exception is in England where Building Regulations now disallow the use of 0.6mm as a liner in domestic installations).

Prima Plus 1mm can be used for the same applications as Prima Plus. Additionally it is specifically designed for connecting solid fuel appliances to existing brick stacks or a twin wall chimney. It provides internal fluing of domestic woodburning, coal and
multi-fuel stoves and boilers with normal operating temperatures up to 540°C and short firing up to 760°C.

Prima SW is a medium corrosion-resistant 304 BA grade stainless steel single wall flue system designed for use internally on gas and oil-fired (28 sec only) air and ceiling heaters and natural draught boilers with constant operating temperatures up to 250°C.
