1.4 System Pressure – System & Combi Boilers
When the boiler is connected to a sealed system the
system pressure should be periodically checked. The
minimum pressure, as indicated by the black needle,
is 0.5 bar when the boiler is cold and 2.5 bar when
the boiler is at normal operating temperature. If the
pressure is outside this range contact Warmflow or
your installer.
1.5 Filling Loop
If the system pressure falls below the minimum
(e.g., due to the removal of a radiator for
decorating purposes) then the system should be
topped up using the filling loop valve. After the
system has been topped up the pressure gauge
should read 1 bar when the system is cold. The
valve must be fully closed and the flexible filling
loop removed from the valve, expect a small
water loss from the pipe.
Special attention must be given to the
concentration of corrosion inhibitors in the system water where there is a need for
topping up. Concentrations must be restored to inhibitor manufacturers‟
recommendations and monitored going forward.
Frequent or routine topping up of the system should not be necessary and may
prove harmful to the appliance. Should topping up prove necessary on a frequent
or routine basis you must contact Warmflow or your installer.
1.6 Combi Control Panel
The heating control thermostat is user adjustable from 50°C to 80°C. In order to
provide an additional level of safety there is a high limit thermostat which has a cut
off point of 110°C; this is factory set and is not adjustable. The high limit
thermostat is located under the control panel to the left hand side, press button to
reset. As standard the panel is fitted with two on/off selector switches to control
hot water and central heating. These switches can be replaced by the optional two
channel digital programmer, instructions for use are provided in the main boiler
handbook.
This boiler must be serviced annually. Contact Warmflow for further details.
In the event of a breakdown please contact your commissioning engineer who
should then contact our service department whilst at your home, to report the
fault.
