Connecting the Pipe Work to the Collector
There are many ways in which to attach the pipe work to the collectors, different installers
preferring different methods.
The flow and return pipes are connected to the collector by means of 22mm compression
couplings. These may be the type supplied with the flexible stainless pipe, standard 22mm
brass fittings (between 2 collectors for example), right angle 22mm brass fittings or 22mm T
brass fittings (if an external air vent is fitted).
In all cases, a hole must be cut in the tiles at each end of the collector (or at each end of a
multiple collector array).
The 22mm copper pipe tails protruding from each end of the collector can be trimmed using a
pipe cutter to give a closer fit. However, it is recommended that there remain a 5mm gap
between the end of the collector and the fitting to allow for expansion/contraction.
Using DN16 2-in-2 Pre-Insulated Stainless Steel Flexible Pipe
The 2 pipes can be separated by cutting the insulation apart using a craft knife or similar:
Cut around the insulation to reveal the pipe, this is then cut using a pipe cutter.
