5.7 Assembly of the exhaust gas
system
Assembly with downward slope
The exhaust gas duct must be installed with a slope towards the Paramount, so
that the condensed water can drain from the exhaust gas duct to the central con-
densed water collector of the Paramount.
The min. downward slope is:
- Horizontal exhaust gas duct: min. 3° (min. 5.5 cm per one metre)
Working gloves
Caution! Danger of injury by missing working gloves!
Wearing working gloves is recommended during the assembly work, particularly
while cutting the pipes.
5.8 Gas connection
The gas side connection must only be carried out by an GasSafe heating engineer.
For the gas side installation and setting, the factory setting data of the equipment
and optional label should be compared with the local supply conditions.
An approved thermally activated shut-off device is recommended.
In case of existing old gas pipes, the installation of a gas filter is recommended.
Residues in pipes and pipe joints should be removed.
5.9 Check tightness
Danger! Danger of life from gas!
The entire gas inlet pipe, particularly the joints must be checked for leakages be-
fore commissioning.
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!
5.10 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.
Liquid Petroleum Gas design
Note:
The cause may be lack of gas in case of the fault message "133” (see fault
code table); therefore, the liquid gas tank must be checked for content.
5.11 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. 8 ).
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.
