Residues in pipes and pipe joints should be removed.
5.11 Check tightness
Danger! Danger of life from gas!
The entire gas inlet pipe, particularly the joints must be checked for leakages be-
fore commissioning.
5.11.1 Purging the gas line
The gas line has to be purged before commissioning. For this, open the measuring
nozzle for the connecting pressure and purge by observing the safety precautions.
Check for tightness of the connection after purging!
5.12 Factory settings
The set gas type can be seen on the affixed label on the burner. The data, set by
the manufacturer, has to be checked with the local supply conditions before insta-
lation of the Paramount. The gas pressure controller of the gas valve has been
sealed.
5.13 Supply pressure
The supply pressure must lie between the following values:
- for natural gas: 18 mbar - 25 mbar
- for liquid gas: nominal 37mbar
The connecting pressure is measured as pressure in the gas flow at the measuring
nozzle of the gas valve ( Fig. 9 ).
Danger! Danger of life by gas!
The Paramount must not be started up when the supply pressures are outside the
said range!
The gas supply company should be informed.
5.14 CO2 -Content
The CO
2
content in the exhaust gas must be checked during commissioning and
during regular maintenance of the boiler, as well as, after reconstruction work on
the boiler or on the exhaust gas system.
CO
2
-content during operation see section Technical data.
Caution! Risk of damage of the burner!
Too high CO
2
-values can lead to incomplete combustion (high CO-values) and
damage to the burner.
Too low CO
2
-values can lead to ignition problems.
The CO
2
-value has to be set by modifying the gas pressure at the gas valve (see
Fig. 9 ).
The air quantity set in the factory must not be changed.
5.15
Changing over from LPG to
natural gas and vice versa
Danger! Danger of life by gas!
The gas type of the Paramount must only be modified by an approved heating spe-
cialist. Use the BRÖTJE conversion set for LPG (accessory). The instructions of the
conversion kit must be observed!
The CO
2
-content has to be set by adjusting the nozzle pressure at the gas valve
(see section Guide line for nozzle pressure)
The CO
2
-content must be between the values according to section Technical Data
at full load as well as low load.
