- Flue temperature values refer to an air inlet
temperature of 15°C and flow temperature of
50°C.
- The data relevant to domestic hot water
performance refer to a dynamic inlet pressure
of 2 bar and an inlet temperature of 15°C, the
values are measured directly at the boiler outlet
to obtain the data declared mixing with cold
water may be necessary.
- * Specific capacity 'D': domestic hot water
flow rate corresponding to an average increase
of 30K, which the boiler can supply in two
successive withdrawals.
To achieve these higher flow rates the flow
restrictor must be removed from the cold inlet
connection. See Section 1.15 item 35.
