In communal or LPG installations where the gas rate cannot be
measured it is acceptable to measure the combustion rate as
described in the servicing section.
• On completion, press the "reset" button to reset the boiler.
• Gas rates for both central heating and hot water can be veried
using the test program P.03 and P.01 respectively.
11.7 Testing heating system
• Ensure that the external controls and programmer are calling
for heat.
• Fully open all radiator valves, see chapter "Appliance
installation > Recommendations before installing > Heating
circuit design".
• Activate the C.H. function on the appliance's control panel.
• Balance the radiators as required to give the required system
dierential.
• Turn o all radiators that can be shut o by the user and check
to see if less than the maximum dierential allowed of 20°C
can be achieved across ow and return.

IMPORTANT:
Should the appliance require adjustment refer to the
"Specic adjustment" section overleaf.
• Allow the system to reach maximum temperature then switch
o the boiler by isolating from the electrical supply.
• Drain the entire system rapidly whilst hot, using the drain taps
at all the low points of the system. Fill and vent the system as
described previously in chapter "Commissioning > Filling the
CH system (Central heating)".
• Adjust the boiler temperature controls and any system controls
to their required settings.
11.8 Testingdomestichotwatersystem
• Open a hot-water tap.
• Check that the temperature obtained is compliant with the
setting on the appliance.

the surface of the boiler casing.
GB: It is a requirement that the “Benchmark” Installation,
Commissioning and Service Record is completed and left with the
