Contura C 460 Installation Instruction page 17

Lay the first insulating block on top of the sealing plate. Make
sure that the insulation forms a tight seal around the flue base
(the start section of the flue) and the concrete surround. Then fit
the second insulating block in place. This has a larger hole in the
middle and should form a tight seal with the outside of the chimney
module. Fit the bottom chimney module into place.
Screw the front section of the ceiling insulation into place leaving a gap of 4–5 mm to the flue casing. Make sure that the ceiling insulation is
held in place firmly against the ceiling. Hold the rubber sealing strip so that the gills are facing the flue casing and press the strip into place
in the gap around the chimney. Seal and use insulating blocks to insulate in the roof/floor above the ceiling insulation.
