User instructions
Introduction
The
icon 23 t
and
icon 28 t
boilers are wall mounted combination boilers providing central
heating and instantaneous domestic hot water.
These instructions should be carefully followed for the safe and economical use of your boiler.
GAS LEAK OR FAULT
If a gas leak or fault exists or is suspected, turn the boiler off and consult the local gas company or
your Installer/Service provider.
IN CASE OF POWER SUPPLY FAILURE
The boiler no longer operates.
As soon as power supply is restored, the boiler will restart automatically.
IN CASE OF LOSS OF WATER IN THE SYSTEM
CAUTION: The boiler is installed as part of a sealed system which must only be drained and
filled by a competent person.
If the pressure shown on the pressure gauge is less than 1 bar the system must be filled up
immediately.
Important notice: A central heating system cannot operate satisfactorily unless it is properly filled
with water and unless the air initially contained in the piping systems has been properly bled off. If
these conditions are not satisfied, air noise will occur within the system.
AIR IN THE HEATING SYSTEM
Persistent air in the heating system may indicate leaks in the system or corrosion taking place. Call
your Installer/Service provider.
OVERHEATING SAFETY
In the event of problem, the overheat safety device causes
safety shutdown of the boiler. If this happens, call your In-
staller/Service provider.
Controls and lighting
The control panel, located at the lower front of the boiler
casing, see diagram, allows the boiler to be started, shut
down, controlled and monitored during use.
Make sure that:
— The boiler is connected to the electrical supply.
— The boiler gas service cock is open.
— The pressure gauge reads between 1 and 2 bar.
The boiler is now ready to start.
