Notes:-
1. For larger properties the incoming main should be a minimum of 32mm MDPE
with a pressure of not less than 2 bar dynamic and an adequate flow in line with
the pipe sizing calculations.
2. The flow rates are based on a 35°C temperature rise and assume normal pressure
and adequate flow to the appliance. The actual flow rate from the appliance is
automatically regulated to a maximum of 28 litres/min.
3. Unit is supplied on a 100mm high installation base.
4. The domestic hot water outlet temperature is automatically regulated to
approximately 52°C (± 2°c) at the bath flow rate of 18 litres/min recommended by
BS 6700. The temperature is not user adjustable.
5. The suggestions under Model Selection for any appliance size are maximums, and
in the same way as the criteria used for sizing the water distribution systems, are
based on a typical diversity of use. Therefore it will be impractical to expect the
appliance or the water distribution system to be able to support simultaneous use
of the sanitary fittings shown.

6. In projects requiring Building Regulations
approval, the maximum floor area figure
must not be exceeded to ensure compliance
with ADLI requirements. However, final
selection should be made on the basis of the
minimum model (appliance size) that meets
all the criteria i.e. heating load/number of
bathrooms and shower rooms/floor area.
