Application
Twin wall gas heating system designed for cost-effective venting of residential and small commercial atmospheric gas appliances with input up to 60kw. It is suitable for both internal and external use, either as a complete system or in combination with masonry, i.e. flue blocks or brick chimneys.
Note that BS 5440-1 requires the use of a stainless steel insulated flue on external runs exceeding 3 metres. K Vent fulfills this requirement and is fully interchangeable with the B Vent range.

• Twist-lock bayonet jointing system.
• No locking bands required.
• Aluminium inner liner and aluzink outer case which can be painted if required.
• 12.5 mm air gap between case and liner keep case temperature low.
• 0-90° adjustable bend.
• When joint is made, the liner covers the jointing collar, shielding it and permitting easy drain-down of any moisture in the flue.
