etrate through the roof. The standard kit comes with 1.2m of
twin wall ue (post fan). Note total combined maximum vertical

max 8m polypro).
Use standard methods to ash the roof penetration, the instal-
lation must be weather proof and conform to all local council

Mount the fan assembly box to roof framing using timber or
builders strapping, ensuring the ue is vertical and rigidly
mounted.
Aim to have the fan box mounted as high as possible, mainly to
allow sucient fall for condensation drainage if the exi-ue is
to run horizontally.
Ensure there is sucient space below fan box to have access to
t the exi-ue tubes and to allow owing bends if required.
