Diagram C2
For reasonable connection working space allow 150-200mm from rear of device to wall.
The device is 600mm wide and the centre of the trap is 300mm from each side.

‘S’ TRAP PIPE POSITIONING
FREE STANDING
‘P’ TRAP PIPE POSITIONING
The centre of the soil line to receive the ‘S’ Trap
should be approximately 272mm from the back wall.
To allow for normal recommended minimum side
service access, space soil line 600/700mm from side
wall.
If space restrictions do not allow for recommended
side service access, we suggest preference be given
to providing the most space available on the right
hand side as you look at the front of the device.
This will ease any difficulty in servicing the steam
tank element and probe.
The centre of the soil line to receive the ‘P’ Trap
should be approximately 410mm from the floor
when the device is positioned 150mm from the wall.
Because this pipe is graded to 5° this measurement
will vary as the device is installed closer or further
away from the back wall.
Steam Venting
No external vent pipe work is required as the device is designed to condensate all visible steam internally.
