a
Danger!
Risk of death caused by improper gas
installation!
Tension in the gas line may result in leaks
or an explosion.
> Make sure there are no stresses in the
gas lines when it is installed.
b
Caution.
Risk of material damage caused by incor-
rect gas installation.
Excess test pressure may cause damage to
the gas valve.
> When checking the gas valve for leak-
tightness, use a max. test pressure of
1.1kPa (110mbar).
> During the gas installation, ensure that
the home pressure regulation for the
required gas flow pressure of 5mbar is
maintained in accordance with the tech-
nical data (
¬section18).
b
Caution.
Risk of material damage caused by con-
taminated lines.
Foreign bodies, such as welding remnants,
sealing residue or dirt in the supply lines
for gas, may cause damage to the boiler.
> Blow the gas line thoroughly clean prior
to installation.
b
Caution.
Risk of material damage caused by the
incorrect gas type.
Using the wrong gas type may cause a fault
shutdown on the boiler. Furthermore, igni-
tion and combustion noise may occur in the
boiler.
> Only use the gas type specified in the
type overview (
¬section1.5).
5.2 Connecting the gas line
5.1 Gas connection
> Fit an approved gas valve to the unit with a screw
