SECURING THE CURB
When the frame is correctly positioned, it is essential to secure the assembly with a disconnected stitched welded seam (20 to
30 mm every 200 mm
- - - -) along the outside or by using an alternative method.
CURBING AND FLASHING
Outside of frame must be insulated with rigid type insulation;
We recommend a minimum of 20 mm thick insulation (2 figure 24).
Check that the insulation is continuous, counter flash and seal around the frame
as shown in (1-figure 24).
CAUTION: To be effective, the upstream must end below the drop edge (3 - figure
24).
Where pipes and electrical conduits extend through the roof, flashing must
conform to local codes of practice
Before installing the equipment, make sure that seals are not damaged and check that the unit is secured to the mounting
frame. Once in position, the bottom of the equipment must be horizontal.
The installer must comply with local authority standards and specifications.
