7 Functional checks commissioning (part II)
7.1 Funtional checks
After installing and checking the gas supply pressure, perform a function check before
commissioning the appliance and handing over to the user.
● Commission the appliance according to the relevant operating manual.
● Check the gas supply pipe, flue system, heating system and the hot water pipes for
leaks.
● Check that the flue system has been installed properly according to the flue system
installation manual.
Checking for tightness of the flue gas installation and flue gas recirculation
● Check the integrity off the flue gas installation accord-ing to TB 200.
Should the flue gas installation be longer than 2 m we strongly recommend to check the system
for flue gas recirculation as described below.
● For checking the system for flue gas recirculation use the combustion air analysis point
shown at 8.1.
● Use the flue gas analyser.
● If you detect any CO or CO2in the fresh air, search for the flue gas leakage or
recirculation.
