Sealing checks

IMPORTANT NOTE: After assembling the kit curb and prior to put the machine on it, make sure to put a poly-
ethylene foam on the curb upper fl ange side (must be delivered in the curb package).

CURBING AND FLASHING

Outside of frame must be insulated with rigid type insulation. We
recommend a minimum of 20 mm thick insulation.
Check that the insulation is continuous, counter fl ash and seal around
the frame as shown.
CAUTION: To be effective, the upstream must end below the drop edge.
Where pipes and electrical conduits extend through the roof, fl ashing
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 specifi cations.
