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)

Note:
The RD-700 & RD-800 offer several options that change the installation process. The -F
Deck Flange/Adustable Extension option is the first one described. Drains ordered with the
-B Sump Receiver are listed second. The "F" flange option allows for adjustable extension
and no need for reinforcement, while the "B" sump receiver allows for installation flush with
the roof. Make sure you have ordered correctly before preparing for installation.
