9 Exhaust gas connection
A3 / 62, 11, 12, 21, 22
Room air-dependent gas furnaces with fans in
front of burners without flow guards and total
rated load in installation space greater than
14kW.
Updraft lines are not required.
Exhaust gases must be directed outside through
kitchen ventilation systems. Type A gas applianc-
es first emit exhaust gases into the room, and
must promptly be extracted via the kitchen ven-
tilation system.
Monitor the exhaust vent to ensure that gas
is only fed to the burners when extraction is
ensured.
