Gas supply
Check the gas supply connection to the
boiler for tightness. If any leakage is
found, reseal the leakage before star-
ting the boiler!
Remove any air between the gas valve
and the gas line. This can be done at
the test point (1) at the gas pressure
switch.
Don’t forget to close the test
point afterwards!
Check the gas type and values with the
local gas company, in order to know for
which gas type the boiler should be
commissioned.
Condensate connection
Remove the syphon (2) from the con-
densate connection. Fill it with water
and place it back in the original posi-
tion. Make sure the syphon is filled
before starting the boiler, in
order to prevent flue gases dischar-
ging through the condensate connec-
tion!
Flue and air intake connections
Check whether the flue and air intake
systems are made according to the
national and local regulations. Installati-
ons which don’t comply with the regula-
tions, are not allowed to be commissio-
ned.
Make sure that all connections are free.
The size of flue gas and air intake con-
nections may not be reduced.
