Welcome to Mi-Flues MI-Flues is a Blackpool based company with factories and distribution centres across England, Scotland and Ireland, and are dedicated to the development of the highest quality flues and chimney products. Established in 1996, MI-Flues has grown to become one of the most respected manufacturers of chimney products in the industry, constantly pushing the boundaries of products specification and design, this has led to the introduction of the TWPro family of flue products.
KEY BENEFITS TWPro is a high quality, multi-fuel, stainless steel twin wall chimney system designed for use with all solid fuel, wood, coal, gas, oil and pellet heating appliances. It is tested to a maximum operating temperature of 600°C and comes with a 25 year warranty. TWPro has exceptional thermal properties which have allowed it to be classified as G50. The 50mm clearance required to combustible materials also applies when it is installed in an enclosure.
INSTALLATION & DESIGN CONSIDERATIONS When designing the flue system the following points should be considered:1. The internal diameter of the flue system should not be less than the size specified by the appliance manufacturer. 2. Ensure that the flue pipe connection from the appliance rises vertically for at least 600mm before any change of direction is contemplated. 3. The minimum height for any solid fuel flue system is recommended to be 4.5m from the top of the appliance. 4.

FIRE STOPS Firestop Plate Non-Ventilated (Gas and Oil) A Firestop plate is used to allow the chimney to pass between floors, for example, when you need the chimney to go through the ceiling on the ground floor through to the first floor. The steel plate is designed to provide the appropriate distance between the flue and the adjacent flammable materials, according to both fire and building regulations. A plate must be used top and bottom of the floor penetration.
