Roof Drainage - Installation Guide
3. INSTALL BODY
Install body so that the 昀氀ange is at or
just below roof deck level. If the body
is not cast in it should be secured to
the deck. Use a wide 昀氀anged body
for timber decks. The 昀氀ange can be
drilled for 昀椀xings or use an underdeck
clamp (33.9610 or 33.9620). If the deck
is recessed for the 昀氀ange consider the
need to reinforce the cut timber edge.
Note: Membrane 昀氀ange level is
determined by roof build up.
4. DRESS MEMBRANE AND CLAMP
Dress the membrane over the 昀氀ange
over the edge of the body sump in
accordance with the manufacturer’s
instructions, ensuring that the
membrane does not restrict the outlet.
Ensure that the 昀氀ange is at or below
the level of the membrane.
Bolt the membrane clamping collar to
the body using the supplied 昀椀ttings.
Thin membranes may require the
screw length to be reduced.
