General information for gas operation

When installing a gas combustion system, regulations
and guidelines must be observed (i.e. Local Codes of
Practice and Regulations).

The subcontractor responsible for the installation or
changes to the gas system must inform the gas
supplier of the type and extent of installation planned
and the work intended.
The subcontractor must ascertain that an adequate gas
supply to the installation is ensured.

Installations, alterations and maintenance work on gas
systems in buildings and below  ground, must only be
carried out by installers who have a contract with the
gas supplier.

The gas pipework must be subject to a preliminary and
main test or the combined loading test and soundness
test, according to the pressure range intended. Burner
must be isolated.

The air or purge gas required for the test must be
expelled from the pipework. The pipework must be
completely purged.

Gas characteristics

The following information must be obtained from the gas
supplier:

Type of gas

Calorific value in MJ/m

3

or kWh/m

3

Max. CO

2

content of flue gas

Gas supply pressure.

Pipe thread connection

Only tested and approved sealing material should be
used. Please observe the prevailing user instructions!

Soundness test

see Ch. 4.6

Conversion to other gases

When converting to another gas type, a conversion kit
and re-commissioning is required.
