11.3 BRIVIS AD WINTER SEAL INSTALLATION
The Winter Seal can be fitted into the dropper duct before or after the dropper has been installed, but it is important
to ensure that:
•
Dropper duct is square
•
The dropper duct seam and the large 45º fold-up corner are to the high side of the roof as shown in the drawing
below, otherwise the flaps will not open correctly.
•
The Winter Seal is level and a minimum of 120 mm down from the top of the dropper (150 mm maximum)�
•
On the inside surface of the dropper duct, measure and mark points 120 mm down from top of dropper in each
corner� Join the marked points, drawing four level horizontal lines on the inside of the dropper duct to provide
the height position to fix the Winter Seal.
•
Use pliers to bend fitting tabs on Winter Seal sides out at 45º, and bend up the large 45º fold-up corner.
•
Hold the Winter Seal by the solid corner (90º) and lower into dropper with small 45º corners aligned diagonally
across the dropper duct� Lower until small corners line up with marked lines� (See diagram below)
•
Rotate the fold-up corner up until the frame aligns with the marked lines allowing fitting tabs to jam tight against
the dropper duct sides�
•
Check again that the large 45º fold-up is in the correct corner as per previous instructions�
•
Align the top edge on the marked lines and drill through frame holes from inside to out� Pop rivet or screw from
outside to in, making sure screw or rivet tails do not interfere with the seal’s operation�
NOTE
Fitting tabs should be straightened before screwing or riveting.
•
Route the cables through the
45º fold-up corner and bend the
45º corners down to seal� The
large fold-up should hold the
cable against dropper duct away
from the Winter Seal�
•
Ensure flaps on Winter Seal
operate freely�
