5. Instructions For Use
• In order to guarantee safety and correct operation, it is essential that all the tests are
carried out by a competent and responsible licensed service person before lighting up
the boiler.
• The tests are described in the installation, operation and service instructions manual in
Section 15 Commissioning.
• Ensure that the Central Heating circuit is regularly filled with water checking that the
pressure indicated on the temperature and pressure gauge (4 on figure 3.2) is not
lower than 1 bar (14.5 psi) as shown on figure 5.1.
• If the pressure reading on the pressure gauge is below 1 bar (14.5 psi), then the
system will require filling. An automatic filling valve is normally provided by the installer
for this purpose.
• If you are in any doubt regarding this procedure you are advised to contact your
Installer or an Approved Service Person.
• This appliance is provided with a built in anti-freeze system that operates the boiler
when the temperature is below 41 °F
• Therefore, when the boiler is not lit or used in cold weather, with consequent risk of
freezing do not switch off the boiler at the circuit breaker or close the gas inlet
cock.
• When you expect not to use the boiler for a long period follow the instructions given in
section 5.6 on page 14.
• Isolate the boiler from the electrical
supply at the circuit breaker.
• The boiler should have been installed
with an automatic fill valve, external to
the unit. Open the cold water supply
to the automatic fill valve.
• The pressure should be 1 – 1,5 bar
(14.5 – 22 psi).
• The automatic fill valve should
maintain this pressure, but not exceed
it.
Air introduced into the boiler during this filling process will vent through the automatic air
purger fitted to the boiler. You may also find it necessary to vent air from your heating
circuit using the installed vents, however be aware that excessive venting will cause the
pressure in the system to drop. Always ensure that the pressure gauge is set at the
required pressure.
