Roof kits and their relevant manufacturer codes:
Horizontal Installations
(DF400 only)
With any DF400 installation where the collector is installed horizontally on a wall
façade or roof surface; the airvent on the collector manifold must be the highest
point of the collector, otherwise air in the system will remain in the pipes within the
collector tubes and be difficult to flush out. Airlocks in the pipes will stop circulation
through the system.
When the collector is orientated correctly, i.e. with the manifold slightly higher than
the base of the collector, (see below) air will be forced back into the system. In this
instance the air separator will prevent air from circulating.
Metal Roof Fixings
Kingspan also supply roof fixing kits for metal and other commercial roofs. Two options
available utilise appropriate clamps so the fabric of the metal roof is not penetrated.
Note the minimum and maximum distances on each fixing kit.
The distance between the vertical rails on each fixing kit should be between 600mm-
1100mm on 20 tube systems and 800-1400mm on 30 tube systems. This is illustrated
on each roof kit diagram.
Note that the fixing clamps on the side rails are preset for ease of on-site installation.
