"F" Deck Flange Installation Instructions
The use of a 10 ga. zinc plated steel flange helps to reduce the risk of a crooked or
off-set of the leader pipe. It enables the roof drain to be adjusted to insulation
height and is recessed in the center to accept the roof drain body and eliminate
the pooling of water in and around the drain. The flange eliminates the need for
reinforcement of the roof drain.
Place the flange over the opening. Flange may be fastened to the roof deck if desired.
Line the flashing clamp on the body of the roof drain up with holes in the flange and
secure with screws. (provided)
