Gas supply
Check the connection for the gas
supply to the boiler for a leakproofness.
Possible leaks of must be sealed
before the boiler is started.
De-aerate the gas pipe and the gas
valve.
Request information on the gas type
and values from the local gas supplier,
so as to make sure that the boiler is
operated with the correct gas type.
After assembly of the boiler, all gas-
carrying pipes must be checked for
leaks.
Condensate connection
Make sure that the siphon has been
lledbeforetheboilerisstartedup,so
as to prevent emission of waste gases
from the condensate connector.
Filling the siphon after assembly.
Removed the siphon (7) from the
condensate connector in the boiler. Fill
it with 0.3 litres of water and then turn it
hand-tight back into its original position.
Flue gas and air supply connections
Check that the connectors for waste
gas and air supply correspond to the
domestic and regional regulations.
Facilitiesthatdonotfullthese
regulations may not be taken into
operation.
Make sure that all connectors are free.
Flue gas and air supply connectors
may not be reduced in size.
Before taking the boiler into
operation, it must be ensured that
dirt particles, which may be present
in the heating facility, are removed
by a thorough ushing of the piping
system.
Water pressure
Open the valves to the system. Check
the water pressure in the system. If the
water pressure is too low (minimum
operating pressure > 1.0 bar), then
it must be increased at least to the
minimum water pressure in the table.
Hydraulic system

hydraulic system in such a way that a
