Roof Drains - Installation Guide
1. CHECK THE DIMENSIONS
Before installing, check the total height
of the components to ensure the correct
finished level is achieved. Allowance must be
made for the thickness of any membranes
used and, where applicable, roof insulation.
2. FIT SPIGOT AND CHECK OUTLETS
Screw spigot, where required, into the body,
using a suitable sealant to create a watertight
joint. Position the body in the roof deck and
ensure the outlet is accessible.
3. INSTALL BODY
Install body so that the flange 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 flanged body for timber decks. The
flange can be drilled for fixings or use an
underdeck clamp (33.9610 or 33.9620). If the
deck is recessed for the flange consider the
need to reinforce the cut timber edge.
Note: Membrane flange level is determined
by roof build up
