2.11 Filling the condensate drainage system.
Take off the plug on the condensate drainage system and fill it with water amounting to 1
glass so that flue gases do not come out.
Attention. Do not operate the boiler if the condense drainage system is empty. It
may cause intoxication from burnt gas.
2.12 System start-up.
Before starting up the boiler, check that the relevant actual rules have been performed.
Make sure that:
 all fuel pipe connections are tight and completely sealed; first check the with the
isolation valve closed, then with the isolation valve open (while keeping the gas valve
closed). No gas presence is supposed to be indicated by the gas meter in 10 minutes;
 the boiler is supplied with preset gas;
 the gas flow rate is as specified in this manual (see par. 3.7);
 the main switch is working correctly;
 the air/flue ducts (if present) are not obstructed. Do not start up the boiler if the controls
do not satisfy the requirements.
