Flue Preparation
Unpack flue duct, flue trim and air duct.
Measure overall wall thickness. If this is between
280mm (11in) and 355mm (14in), use flue as
supplied without alteration.
For wall thickness between 102mm (4in) and 280mm
(11in), air duct and flue duct are required to be
shortened.
Using the indication on the duct, mark accordingly to
table below.
Bend tabs as shown.
Using tin snips, cut around ducts at appropriate
mark. Remove any sharp edges.
