Mi-Flues VIT-Smooth – 250mm Pipe with Damper – Ø125mm

Suitable for gas, oil and solid fuel appliances with temperatures up to 600°. VIT-Smooth pipe should only be used as a connecting pipe between your appliance and Flue Liner / Chimney Stack / Twin Wall Flue System. VIT-Smooth pipe should NOT be used to pass through ceilings or combustible walls.

VIT-Smooth is a single skin connecting flue system manufactured in zero carbon steel with Powder vitreous enamel coating in a matt black finish. Suitable for gas, oil and solid fuel appliances with temperatures up to 600°. You should not install a piece of VIT-Smooth 100mm within 375mm from combustible material, e.g. wood, plaster boards, etc. When installing make sure VIT-Smooth is installed the correct way up – the smaller diameter should always be pointing downward.

This is because all the condensates will stay within the flue system and not pass to the outside of the VIT-Smooth. VIT-Smooth is a friction fit joint so does not require sealing of the joints, For extra security if desired each joint could be coated with a jointing compound (fire cement or high temperature silicone sealant).

This makes sure that no condensate can escape and spoil the appearance of the pipe. VIT-Smooth has been designed to be cut, but care must be taken to cover any exposed steel with high temperature paint as this will rust over time. When installing appropriate PPE should be worn at all times.

You should make provision for inspecting and cleaning the chimney. This is particularly important on solid fuel applications. You can achieve this by installing a VIT-Smooth with an access door at changes of direction.

It is recommended that chimneys serving solid fuel appliances be swept and maintained as frequently as necessary but at least once a year.
