Note: The solar collectors (both flat panel and evacuated
tube) must be installed at an angle from the horizontal.
This is to ensure that any air in the system will travel to
the air vent valve located on the outlet connection of the
collectors.
The distance between the end of the collector rail at the
outlet side of the solar collectors and the horizontal must be:
10 - 15 mm (for one solar collector)
20 - 30 mm (for two solar collectors)
30 - 45 mm (for three solar collectors)
If the roof material is uneven where the collectors are to be
installed, then it may be necessary to add an additional 10
mm to the above distances for each collector.
