Hi,

I'm hoping someone can help me. My new house has the above boiler installed but I have no manuals etc...

My problem is that the hot water flow is pathetic. I was wondering if there is a flow restrictor built into this boiler and where it is and if it can be removed.

Thanks,

Ian.

temperature.
To set the D.H.W. flow, procede as follows:
– select Summer position “ ” and turn the D.H.W. thermostat
to max.;
– fully open the D.H.W. tap furthest from the boiler;
– check that the boiler is firing at maximum burner pressure;
– adjust the D.H.W. flowrate by turning the restrictor lever
on the divertor valve until a D.H.W. temperature rise of
approx 35°C is achieved. This corresponds to the
flowrates shown in Table 4;
– turn off the tap;
– remove the pressure gauge and refit the sealing screw;
Remember that the flow rates and corresponding temperatures
of use of hot water, given in Table 4, have been obtained
by positioning the selector of the circulation pump on the maximum
value.
Should there be any reduction in the D.H.W. flow rate, the
filter installed on the inlet to the pressure switch valve will
need cleaning.
To gain access to the filter, first close the cold water isolation
valve (20, figure 2), drain the D.H.W. circuit via the lowest
tap, make provision to collect a small discharge of
water, then loosen the brass swivel connection to access
the filter.

no pics i'm afraid

The boiler will give 9.3 litres/minute at a 35*C temperature increase.

If the output is less than this the DHW HE is probably blocked by debris because the system was not power flushed when the boiler was installed.

cant see it affecting the dhw flow though
will affect the temp rise
