SLOPING CEILING INSTALLATION
The instructions for a sloping ceiling and a flat ceiling are the same except for the following:
A) The 200mm Inner Liner, and the 250mm Outer Liner will need to be trimmed to the angle required to suit the ceiling
(between 15-45 degrees).
B) Fitted to the non swaged end of the 200mm Inner Liner are 3 x locating brackets. These will need to be removed and
not used.
C) A 150mm-200mm, and a 200mm-250mm spider bracket will be needed at the ceiling end of the liners.
D) Point 10) will differ from the flat ceiling installation, in that the 200mm Inner Liner will need to be 6mm lower than the
250mm Outer Liner as shown in Diagram C.
E) Ensure the 150mm-200 spider is secured to the flue pipe, and is free floating inside the 200mm Inner Liner.
F) The 200mm-250mm spider must be secured to both the 200mm Inner and 250mm Outer Liners once they have been
aligned and the 6mm height difference has been achieved.
G) Point 15) will also differ from the flat ceiling installation as the sloping ceiling plate will use ceramic spacers between
the ceiling plate and ceiling. Please do not over tighten the screws.
