Water pressure and quality
Check if the water pressure and quality
meet the requirements. Consult the
chapter “commissioning: water and
hydraulic system” for more detailed
information.
Water flow rate
Check if the water flow rate through the
boiler is within the limits. Consult the
chapter “commissioning: check water
flow” for more detailed information.
Combustion analysis
Check the combustion at full load and
minumum load, correct the settings if
necessary. An additional reference
check at 50% load is recommended.
Consult the chapter “commissioning:
combustion analysis” for more detailed
information.
Gas pressure
Check the dynamic pressure of the gas
supply to the boiler, when the boiler is
running at full load. In case of a boiler
cascade, all boilers should be running
at full load. See technical data for re-
quired values.
Gas tightness check
Check the tightness of all sealed
connections with an approved soap or
electronic analyzer, for example:
• Test points;
• Bolt connections;
• Gaskets of mixing system, etc.
Safety devices
Check the functionality and the settings
of all safety devices connected. Consult
the chapter “commissioning: Check
