To protect the appliance against excessive pressure:
B
Fit a pressure regulator with a safety valve.
6.2
Checking the size of the expansion
vessel
The integrated expansion vessel is pre-charged to
0.75 bar (75 kPA).
Where the system volume is more than 100 litres or
exceeds 2.65 bar (265 kPa) at maximum heating
temperature, an additional expansion vessel must be
fitted as close as possible to the appliance in the central
heating return.
All expansions vessels must have the same pressure.

Siting the appliance
Regulations concerning the installation site
B
Observe relevant national regulations.
B
Consult the flue kit installation instructions for details
of minimum clearances required for flue gas routing.
B
Do not install the appliance outside.
If the appliance is fitted into a cupboard or a
compartment is built around the compliance after
installation, then the compartment must be built from or
lined with a non-combustible material.
Combustion air
In order to prevent corrosion, the combustion air must
not contain any corrosive substances.
Substances classed as corrosion-promoting include
halogenated hydrocarbons which contain chlorine and
fluorine compounds. They may be found in solvents,
paints, adhesives, aerosol propellants and household
cleaners, for example..
Surface temperature
The maximum surface temperature of the appliance is
below 85 °C. Therefore no special safety measures are
required to protect flammable materials and fitted
furniture.
Ventilation
This is a room sealed appliance and does not require any
air for combustion from inside the property.
There is no need for ventilation openings to be provided
in the compartment because of the low heat loss from
the appliance casing, if the clearances shown are
maintained (
