2 Safety
a Caution
Inappropriate modifications can cause damage.
Never tamper with the boiler or other parts of
the system.
Never attempt to perform maintenance or re-
pairs yourself.
- Do not damage or remove seals on components. Only
authorised engineers or our customer service may re-
moved sealed components.
d Danger
Risk of scalding.
The water coming out of the tap can be very
hot (ecoTEC combination boiler only).
a Caution
Risk of damage.
Do not use sprays, solvents, chlorinated clean-
ing agents, paint, adhesives or similar sub-
stances in the vicinity of the appliance. These
substances can cause corrosion, including in
the flue system.
Installation and setting
a Important
The appliance must be installed and serviced by
a competent person as stated in the Gas Safety
(Installation and Use) Regulations 1998. In IE,
the installation must be in accordance with the
current edition of I.S.813 'Domestic Gas Instal-
lations', the current Building Regulations and
reference should be made to the current ETCI
rules for electrical installation.
a Caution
The appliance may only be operated with its
case properly and permanently closed.
Otherwise, in unfavourable conditions, material
damage or even injury or death can result.
Filling pressure of the heating system
Regularly check the filling pressure of the heating sys-
tem (see 4.3.2).
Leaks (ecoTEC combination boiler only)
If there is a leak in the water pipes between the appli-
ance and the taps, immediately turn off the cold water
service valve and have your engineer repair the leak.
Frost protection
Your boiler is equipped with a frost protection function:
If the heating water temperature drops below 5 °C when
the main switch is ON, then the boiler goes into opera-
tion and heats the boiler circuit to approx. 30 °C.

h Note
It cannot be guaranteed that water will circu-
late throughout the entire heating system.
If the boiler is not operated for several hours during
very cold weather there is therefore the possibility of
the system freezing.
Please ensure that if you are absent during a period of
frost the central heating remains in operation and all
rooms are kept above freezing point.
It must be remembered, however, that the boiler will be
automatically switched off by the built in monitoring de-
vices if certain faults occur, e.g. interruption in the gas
or electricity supply or faults in the flue gas system. To
overcome this possibility you can drain both the central
heating system and boiler.
h Note
Frost protection and monitoring devices can
only function when the main switch of the unit
is set to the "I" position and the boiler is con-
nected to the electrical supply.
