180 Model Connection Details/Dimensions
Diagram opposite show the connection details
and dimensions for the BoilerMate A-Class HP-
DEM 180 model.
The BoilerMate A-Class HP-DEM units are
supplied on an installation base to allow the
pipe runs to connect to the appliance from any
direction. It is easier if all pipes protrude vertically
in the cut out area shown. Compression or push
fit connections can be used. All pipe positions
are approximate and subject to a tolerance of
+/-20mm in any direction.
Note: All dimensions are shown in mm and
are to the centre line of pipework/gland.
