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
