SYSTEM ASSEMBLY
49
If the roof material is not even where the collectors are to be installed, then it may be necessary to add
10 mm for each collector in the array to the above distances. It is important that the solar hot outlet is the
highest point in the collector waterway so the system functions efficiently.
Note: AS/NZS 3500.4 states a minimum of three (3) screws 40 mm long be used per strap. Longer screws
or anchors may be required to achieve a 40 mm minimum embedment into rafters for a metal roof.
Additional screws or anchors may be required.
Tile Roof: Remove the tiles on the next row above the position of the collector mounting rail to expose the
rafters. Ensure the collector mounting rail is at the correct angle from the horizontal. Once in position, fix
the collector straps to the rafters, using suitable screws or anchors. Replace the tiles.
Metal Roof: Ensure the collector mounting rail is at the correct angle from the horizontal. Once in position,
fix the collector straps to the rafters, through the metal roofing material, using suitable screws or anchors.
Care should be taken not to mark Colorbond
®
or other metal roof sheet with a marking pen and to remove
all swarf from the metal roof as these can cause deterioration of the metal roofing material.
Note: Fixings must penetrate only through the high point in the roof material profile.
