– Should it be necessary to access the areas in the
bottom part of the appliance, make sure that the
system components and pipes are not hot (risk of
burning).
– Before replenishing the heating system, put on pro-
tective gloves.
Commissioning of the MIA HE C10 boiler must be carried out by
professionally qualified Personnel after which the boiler can op-
erate automatically. It may however be necessary for the User to
start the appliance autonomously without involving a technician:
for example, after a holiday . In these cases certain checks and
the following operations must be carried:
– check that the gas isolation and water system valves are open
– using a pressure gauge (1), check that the heating system
pressure when cold is 1-1.2 bar . If this is not the case, open
the filling valve (2) and restore the heating system pressure
until the pressure gauge (1) shows a reading of 1-1.2 bar
– close the filling valve (2).
