CAUTION
These minimum clearances must be maintained
also in consideration of outdoor installations in
confined spaces (e.g. alcoves).
8.5 New installation or installation of a re-
placement appliance
When
Brava Slim HE R
boilers are installed on old systems or
systems requiring updating, it is recommended the installer
checks with appliance supplier for advice:
– the connecting flue pipe is suitable for the combustion tem-
perature of the appliance, calculated and manufactured in
compliance with Standards, current editions, that it is as
straight as possible, air tight, isolated, with no obstructions or
restriction and that it has appropriate condensate collection
and evacuation systems
– the electrical system has been manufactured in compliance
with specific Standards and by professionally qualified per-
sonnel
– the fuel delivery line and the tank (LPG) comply fully with spe-
cific Standards
– the expansion vessel ensures total absorption of the fluid di-
lation in the system
– the pump flow-head performance is sufficient for the system
characteristics
– the system is clean, free of any sludge, deposits, de aerated
and air tight. For system cleaning, please refer to the relevant
paragraph.
m
CAUTION
Gas pipe sizing, flue installation and appliance ventila-
tion must comply with AS/NZS 5601.

IT IS FORBIDDEN
Do not install the boiler in special environments that
may limit its optimum operation (e.g. marine environ-
ment).
8.6 Cleaning the system
Before installing the appliance on a newly constructed system
or replacing a heat generator on an existing system, it is im-
portant that the system is thoroughly cleaned to remove sludge,
slag, dirt, residue etc.
Before removing an old heat generator from an existing system,
it is recommended that the user:
– puts a descaling additive into the water system
– allows the system to work with the generator active for a few
days
– drains the dirty water from the system and flushes the system
with clean water once or more than once.
If the old generator has already been removed or is not availa-
ble, replace it with a pump to circulate water in the system and
then proceed as described above.
Once cleaning operations have been carried out and before in-
stalling the new appliance, it is recommended that a fluid is add-
ed to the water system to protect it from corrosion and deposits.
m
CAUTION
– For further information on the type of additive and
usage, please contact the appliance manufacturer.
– Please remember that you MUST install a Y filter
(not supplied with the appliance) on the heating sys-
tem return (R).
8.7 Water system treatment
When filling and restoring the system it is good practice to use
water with:
– aspect: clear if possible
– pH: 6÷8
– hardness: < 25°f.
If the water characteristics are different from those indicated, it
is recommended that a safety filter is used on the water deliv-
ery pipe to retain impurities, and a chemical treatment system
to protect against possible deposits and corrosion which could
affect boiler operation.
If the systems are only low temperature systems, it is recommend-
ed that a product is used to prevent the development of bacteria.
In any case, please refer to and comply with the legislation and
specific technical standards in force in the country where the
appliance will be used.
8.8 Boiler installation
Brava Slim HE R
boilers leave the factory with a template for in-
stallation onto a solid wall.
For installation:
– remove the cladding (only on models
Brava Slim HE 20 R e
and
Brava Slim HE 40 R e
)
– place the steel sheet template (2) (if supplied) on the wall (1)
– make the holes and insert the expansion plugs (3)
– hook the boiler onto the plugs.
