Finalising position 1. To finalise the position of the Manifold, and tighten the fixings, the two end evacuated tubes must be fitted. An incorrect spacing between the manifold and the bottom rail will mean that the tube end caps will not click securely into place.
Page 10 Section 4: Pitched frame assembly The GG20T and GG30T collectors can be elevated to the required angle on both flat and pitched roofs using the specialised frame pieces supplied. Adjustable angle range: 22 Making up the frame The cross braces (6) and angled bracing section (3) should be cut to the desired length.
