HOW TO FIT THE APPLIANCE TO THE WALL
3.4 - WATER HEATER LOCATION
When selecting the position for the installation of the boiler
please comply to the following safety requirements:
• Fit the appliance in rooms protected from frost;
• The appliance cannot be operated in rooms where
aggressive vapours or dust are present;
• The appliance must be installed exclusively on a vertical
and solid wall, capable of adequately supporting the
weight of the water heater;
• The wall must not be made of flammable material;
•
Leave on each side of the appliance a clearance of 50
mm, at least 200 mm on the upper side and 400 mm on
the lower side in order to allow easy service works.
WARNING
The water heater is not suitable for outdoor
installation.
3.5 - WATER HEATER INSTALLATION
Before connecting the water heater the following
requirements must be carried out by competent and qualified
engineers:
a) The system is flushed out with water in order to
eliminate any solid element which could reach the water
exchanger and affect the proper running of the water
heater;
b) Check that the appliance has been preset for operating
with the gas type available.
This is verifiable via the indication on the packaging and
on the data badge;
c) Check that the chimney/flue pipe has an adequate draught,
does not have any constrictions, and that no other
appliance’s flue outlets have been fitted, unless the chimney
is serving more than one heating appliance, according to
the specific standards and regulations in force. The
connection between the boiler and chimney/flue outlet can
be made only after this verification has been carried out.
For the fitting of the appliance:
- Determine the position of the fixing holes (upper position) of
adequate diameter and use the two expanding hooks as
shown
- Hung the appliance and fix it using expanding screws
