Incorrect installation occurs when the circular hole is cut off center of the leader
pipe extending upwards in the roof.
"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
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 and line the flashing clamp on the body of the
roof drain up with holes in the flange and secure with screws. (provided)
