The BoilerMate A-Class 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. With the standard
appliance (supplied without a ballvalve and overflow) a 15mm valved mains cold branch
should be provided along with a temporary hose connection incorporating a double check
valve to allow the cistern to be easily topped up when necessary (the temporary hose
connection must be disconnected once the appliance is filled). With the automatic fill
model a15mm cold water supply and a 22mm warning/overflow pipe will be required for
the separate feed and expansion tank.
