KLOBER Uni-Line Slate Vent Manual

The Uni-Line Slate Vent is suitable for use with 600mm x 300mm and 500mm x 250mm slates, both natural and
man-made (for other slate sizes consult Klober on [phone]).
When deciding on the position of the Uni-Line Slate Vent consider the following:
• If the vent is sited at the eaves (low-level), at least one full depth course of slates is needed below to allow free air flow.
• If the vent is fitted at the ridge-line (high-level), then at least one full course of slates must be fitted over the head of the unit.
• The vent must be located between two rafters.
• Minimum pitch 22.50°.

Decide in which course the vent is to be
fitted and lay slates up to the course below.
Lay the two slates directly below the vent.
Cut the underlay diagonally and pin back onto
the surrounding battens and rafters. For rigid
sarking board, cut-out the rectangle.
Slide the vent - spigot first - into the opening.
Using the centring line on the vent, align with
the joint line of the two slates directly below.
Fix vent by nailing through centre nail holes.
Mark the area of the two slates to be
removed (hatched area shown above).
Cut out this area.
If required, an additional underlay seal
is available.
Fix the slates either side of the vent, ensuring
that they overlap the side flashing by the
correct distance. 600mm x 300mm slates
should be aligned with the vertical weather
bar (see guide marks on vent).
Using the cut slates as a template, mark the
underlay diagonally as shown.This is the
cut-line.
Fix the cut slates in position, leaving the
underlay opening exposed.
Continue to fix subsequent slate courses as
normal. No slate cutting of the course above
the vent is required.

Follow the 600mm x 300mm fixing
instructions steps 1-2 (as shown overleaf).
Continue to follow the 600mm x 300mm
fixing instructions - steps 3-7 (shown overleaf).
Use the trimmed slates to mark a 270mm
long gap in the middle batten. Cut out this
section of batten.
When fixing the adjacent 500mm x 250mm
slates, they should abut the main vent body
(see guide marks on vent).
Fix an additional 1.2m support batten above
the cut batten (spanning two rafters) and nail
to the adjacent rafters.
At gauges below 225mm, slight trimming of
the slates in the course above the vent, may
be required.
