Pre-Installation Requirements
Planning
Planning the Overlay™ system beforehand will save time during installation and minimise product waste. The direction the pipe runs to and from the ZRU or manifold and use of the return bends will be the main considerations.
The end returns have a flat panel which forms a channel to allow the routing of pipes to multiple circuits in the room. This can be removed where necessary.
Floor areas which don't require pipe circuitry e.g. beneath kitchen cupboards or sanitary ware can be 'blanked' using 18mm plywood or chipboard. This will make better use of the OverlayTM products. This can also be used to 'square off' rooms with irregular walls.

Room Layouts
The following diagrams show some examples of room shapes, pipe requirements and interruptions (pillars, hearths, etc.) which need
to be accommodated.

Pipe layouts in multiple
room installations
Multiple room installations require several circuits and careful planning is required close to the manifold to allow for all pipes
to be accommodated.
1. Wherever possible pipes can simply go through rather than round walls to eliminate the number of pipes requiring access through the entrance of the manifold cupboard.
2. Alternatively leave voids at the edge
of the panels.
3. Using return bends as routers or 4. using supply pipes to heat corridors are all ways of managing the installation in this area
