Gas Vent IL Flue
DEKS Europe has been distributing twin wall flue since 2006 after being anointed as the official Selkirk distributor following the liquidation of Selkirk Manufacturing Europe in 2003. In 2012 DEKS Europe introduced a new twin wall system to the UK market named Seldek.
Selkirk Insta-Lock is a factory made twin wall gas vent system comprising a range of straight lengths, associated fittings and accessories. It is manufactured with an aluminium liner and an outer casing of Zalutite.
The air gap between the outer casing and inner liner insulates the vent and ensures a strong draft at the start of firing in order to minimise condensation. The resulting low external temperature under normal operating conditions permits installation with only 25mm (1 in.) clearance to combustible materials.
Lengths and fittings lock together to provide a rigid flue system and to ensure maximum ease of site assembly. The unique lock tab feature further secures each joint.
The Selkirk Insta-Lock Gas Vent system is available in 5 diameters 102mm (4"), 127mm (5"), 152mm (6"), 177mm (7") and 203mm (8") and is suitable for gas appliances in domestic or small commercial installations with draught-hoods or with a flue gas temperature not exceeding 260°C, and where the appliance is fitted with a draughthood or diverter. Consideration should be made to the sulphur content of the fuel oil which can have a harmful effect on aluminium if excessive condensation conditions are allowed to persist in the flue.
