6.5 New installation or installation of a
replacement appliance
When GO BF boilers are installed on old systems or systems
requiring updating, it is recommended the installer checks that:
– the connecting flue pipe is suitable for the combustion
temperature of the appliance, calculated and manufactured in
compliance with Standards, 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
personnel
– the fuel delivery line and the tank (LPG) comply fully with
specific Standards
– the expansion vessel ensures total absorption of the fluid
dilation 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.

CAUTION
The manufacturer declines all liability for any damage
caused by an incorrect implementation of the smoke
outlet or for an excessive use of additives.
6.6

Cleaning the system

Before installing the appliance on a newly constructed system or
replacing a heat generator on an existing system, it is important
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 available,
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
installing the new appliance, it is recommended that a fluid
is added to the water system to protect it from corrosion and
deposits.

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
system return (R).
6.7

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 delivery
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
recommended 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.
6.8

Boiler installation

boilers leave the factory with a paper template for
GO BF
installation onto a solid wall.
For installation:
– position the paper template (1) on the wall (2) where the boiler
is to be mounted
– make the holes and insert the expansion plugs (3)
– hook the boiler onto the plugs.
