Make sure the room where the unit is
installed meets all the requirements of the
Current Regulations. In particular, this unit
is an “open chamber” type and must only
be installed and operate in permanently
ventilated places. An insufficient supply of
combustion air will compromise normal
operation and the evacuation of fumes.
Also, the fumes forming under these
conditions are extremely harmful to health
if dispersed in the domestic environment.
Otherwise there may be risk of suffocation
and intoxication or explosions and fire..
Therefore the place of installation must be
free of dust, flammable materials or
objects or corrosive gases.
Position the water heater as close as possible
to the hot water taps, near the sink, but
NEVER above a cooktop. It must also
be situated as close as
possible to the flue or
the start of the flue gas
exhaust pipe.
If the unit is installed inside a cabinet
or joined laterally to other elements,
space must be allowed for removing
the casing and performing normal
maintenance activities.
