Notes:-
1. In many cases, large properties will benefit from having 2 smaller appliances located
adjacent to the areas of peak hot water use. This will allow 2 heating zones to be
provided and remove the need to provide trace heating on the hot water system.
2. A plastic feed and expansion cistern will be supplied separately including ballvalve,
float and overflow fitting.
3. 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.
4. Unit is supplied on a 100mm high installation base.
5. The domestic hot water outlet temperature is automatically regulated to
approximately 52°C at the bath flow rate of 18 litres/min recommended by BS
6700. The temperature is not user adjustable.
