Base support Plate with Drain
This component is used to support the chimney directly from the floor. It should be fastened securely to the floor using
bolts or screws provided by others.
Adjustable Top Plate
The wall support is designed to be used internally or externally to provide either initial or intermediate support for
the vertical chimney. It is used in combination with side plates or with cantilever brackets. The turned down edge at
the front of the plates is slotted to allow for the plate to slide along the cantilever brackets and give some positional
adjustment. The female socket on the pipe attached to the underside of the plate should be pushed down onto the
preceding pipe and the joint secured using the locking band provided. The top plate is then attached to the side plates
or the cantilever brackets using the bolts provided through the fixing slots in the top plate (see Fig. 1). The bolts should
then be tightened firmly.
For maximum height of chimney see load bearing details, please refer to tables and diagrams on pages 32-33.
Side Plates/Cantilever Brackets
Once the position of the support has been established in relation to the chimney
route, secure the side plates or cantilever brackets to the wall using expansion
bolts to ensure adequate attachment and support (see Fig. 2).
