Selkirk Insta Lock Gas Vent 

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.

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 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 minimize condensation. The resulting low external temperature under normal operating conditions permits installation with only 25mm (1 in.) clearance to combustible materials.
