Installation Instructions
TRIM COLLAR (90° & 45° VARIANTS)
One piece trim collars are fitted around the Prima Smooth
pipe where it protrudes through the wall (see Fig. 1). They
should be fastened to the wall using an adequate method of
fixing.
CUTTING OF FIXED LENGTH
Where required fixed lengths may be cut on site to achieve
a non standard pipe length. Only the female end of the pipe
should be cut using appropriate cutting tools.The cut female
socket end should then be de-burred to allow the male spigot
of the next component to slide smoothly into the cut female
socket.The pipes are then installed in the usual way with the
male spigot of the next component being inserted into thecut
female end of the pipe.
The cut edge can be protected and covered using the Cover
Band ref. PS029 (Steel Finish), PSB029 (Black) to give a more
aesthetic appearance.

The lowering pipe is used to take the weight of up to 15 x 1m
pipe lengths as they are lowered down the existing chimney
stack. Rope, which is supplied by the installer, should be
fastened to the lowering brackets and the lowering pipe then
lowered gently down the chimney stack with the standard pipe
lengths being added one at a time up to the maximum load of
15m.
