Fidas24: Connecting the Gas Lines

ATTENTION
The relevant safety regulations for working with flammable gases must
be complied with.
The fittings of the gas paths in the gas analyzer may not be opened.
The gas paths can become leaky as a result.
However, if the fittings of the gas paths in the gas analyzer have been
opened (only by trained personnel), a seal integrity test with a leak
detector (thermal conductivity) must always be carried out after they
have been sealed again.
The seal integrity of the combustion gas supply line outside the gas
analyzer must be checked regularly.
Combustion gas which escapes through leak points in the gas paths in
the instrument can cause fires and explosions, also outside the gas
analyzer.
The lines and fittings must be clean and free of any residues (e.g.
particles left over from manufacturing). Contaminants can enter the
analyzer and damage it or lead to false measurement results!
NOTES
The installation of gas connections is described in section "Installing the
Gas Connections (see page 41)".
Follow the manufacturer's installation instructions for the fittings! In
particular, hold the male fittings (gas connections) in place when
connecting the gas lines.
Follow the manufacturer's instructions when laying and connecting the
gas lines.
If gas lines made of stainless steel are connected to the analyzer
modules, the lines must be connected to the building-side equipotential
bonding.
Never connect more than three analyzer modules in series!
