Place and Fix the Product in Position
These products can be very heavy. Due consideration should be given to getting the product onto the roof safely and
extreme care taken during installation.
Glazing Vision supplies woodscrews with the Pitchvent. If fixing to a support structure made from a material other than
timber, ensure the correct type of screws or fixings have been sourced prior to commencing this step.
Before attempting to lift the product, please check that the yellow transport plate(s) are securely attached to the product.
Remove all packaging from the product including polyfoam glass protection and low tack tape.
When removing the packaging, try to keep it intact as much as possible, so that after installation it can be re-used to
protect the product until project completion and final handover.
Using masking tape, tape the plastic packers (supplied) along the jambs and sill, ensuring that the product will sit centrally in the
aperture
–
there should be a nominal
3/8”
gap on all sides (filled with packers). Ensure that these will not conflict with the fixing holes in
the product.
