The space between the uppermost collector
(1) and the ridge is required for the ridge
plate couplers (2) on which the ridge plates
are then laid. To create a level surface, it may
be necessary to fit several roof battens (3).
> Attach a lower ridge plate coupling (2)
(¬ Table 5.1/5.3, Item 16) and check for a
level surface.
> Fit one or two additional roof battens (3)
(¬ Table 5.1/5.3, Item 13) and check that
the drill holes in the ridge plate couplings
align with the battens.
> Lay the ridge plate couplings aside and
screw the roof battens down firmly. Make
sure when doing this
– that the roof battens are resting flush
against the outer edge of the collector,
– that the roof battens terminate in the
middle of a rafter and abut with the
next batten.

With vertical collector position
> Attach the lower ridge plate couplings
(¬ Table 5.1/5.3, Item 16) above the
collector:
– one on the external edge
(max. 150 mm from the edge),
– one per collector joint (central).
> Make sure that the lower ridge plate cou-
plings are resting on the collector frame
slot (1).
> Slide a support board (¬ Table 5.1,
Item 18) through the straps on the lower
ridge plate coupling (2).
> Join the lower ridge plate couplings to the
support board with two No. 2 screws each
(¬ Table 5.2/5.4) using the Torx bit to
prevent it from slipping (3).
> Screw the lower ridge plate coupling at
the top to the roof batten (4).
