2.4 Benchmark standard
The Benchmark initiative is a code of practice
to encourage the correct installation,
commissioning and servicing of domestic
central heating appliances and system
equipment.
A “checklist” is dispatched with every appliance and can be found
towards the back of the Installation, Commissioning and Servicing
Instructions. This is a vital document that needs to be completed by the
installer at the time of installation. It confirms that the appliance has
been installed and commissioned according to the manufacturer's
instructions.
The service record provides space for the recording of regular servicing
of the appliance/heating system and this can become a valuable
document when, for example, you wish to sell the property. The service
record will show a potential purchaser that the heating system has
received regular professional maintenance and servicing during its
lifetime.
The Benchmark initiative aims to:
• Raise standards among professional installers.
• Build and maintain high safety standards in the industry.
• Improve customer satisfaction levels.
• Make a contribution to the nation's commitment to climate change.
3 Prepare for operation
3.1 Open vented heating system
Appliances that can be connected to open vented heating systems will
have the pressure maintained automatically by the header tank feeding
the system.
3.2 Sealed heating system
Appliances that can be connected to sealed heating systems are pre-
pressurised before operation, this pressure must be maintained for safe
use of the appliance.
▶ Check regularly that the pressure is maintained.
▶ Re-charge the system if the pressure indicator reads less than 0.8
bar.
▶ If a permanent significant decrease or increase in pressure is shown
on the pressure indicator, contact your installer or maintenance
engineer.
Pressure indicator
▶ Type of pressure indicator for the system pressure.
– Pressure gauge (an analogue dial showing the pressure)
– Pressure menu (a digital readout of the pressure)
▶ Your appliance may have one or both types of methods to indicate the
system pressure. The type of method used on this appliance will be
detailed in the following section.
3.2.1 Checking the system pressure
If the pressure is too low (≤ 0.2 bar) the system is out of operation and a
warning notification stays on the screen. Fill the water until indicator is in
green zone.
Your installer will advise you of the optimum operating pressure.
▶ Press the menu key [1]. Select and confirm Boiler status.
The screen Boiler status with a pressure indicator [2] appears.
Fig. 2 Pressure indicator for checking the operating pressure
▶ Check the system pressure at the display.
–Indicator in red zone: pressure is too low or too high.
–Indicator in yellow zone: pressure is low or slightly too high.
–Indicator in green zone: pressure is normal.
▶ Top up the heating water, if the pressure is low or too low.
3.2.2 Constantly re-pressurising the system
Constantly having to re-pressurise the heating system should be
investigated as it is an indicator of potential leaks and the concentration
of inhibitor protection in the system will be reduced; this can result in
corrosion within the heating system, reducing efficiency and increasing
contaminates.
▶ Check for leaks on heating system (pipework and radiator valves).
▶ Contact your installer or maintenance engineer if a recurring
significant decrease or increase in pressure is indicated on the
pressure screen.
System pressure increasing:
▶ If the system pressure repeatedly increases and you need to vent air
from the radiators, refer to section 3.3 "Topping up the system
pressure", page 8.
