Supply
Position C
Note: Position A is best suited for gas burner roofcurb. In this
position it is easier to access the burner register. It is also the
most optimal solution in areas where snow can accumulate.
Position the remaining screws on the four corners of the roofcurb.
Use a screwdriver to line up the roofcurb, adjustable angle pieces
and reinforcing angle piece holes opposite each other. Do not
tighten the screws fully.
After levelling the roofcurb perfectly, secure the adjustable angle
piece to the roofcurb using self-tapping screws or spot welds.
Tighten the reinforcing angle pieces down onto the joists.
7.4.3 - Insulation and waterproof sealing
Following insulation is standard for the roofcurb:
■ Self-adhesive rubber gasket of 9 mm around its entire perimeter
■ Thermal insulation of 9 mm on the outer faces of the ducts of
