Route condensate hoses from the side openings to the
building's drainage system. Connect hoses with a con-
stant fall and a pipe vent to the building's drainage sys-
tem.
If required, install a condensate removal pump (acces-
sories).
Note
Pull the hoses out of the appliance far enough to pre-
vent unnecessary bends inside the appliance.
2. Check the gas connections for leaks. Also check
the line to the fuel cell module.
Note
Only use suitable and approved leak detection
agents (EN 14291) and devices for the tightness
test. Leak detection agents with unsuitable constit-
uents (e.g. nitrides, sulphides) can cause material
damage.
Remove residues of the leak detection agent after
testing.
!
Please note
Excessive test pressure can damage the
appliance.
Max. test pressure 150 mbar (15 kPa).
Where higher pressure is required for tight-
ness tests, disconnect the appliances from
. the gas supply pipe (undo the fitting).
