Boiler installation and commissioning tips
The installation must be carried out by a
qualified person who will be responsible for
observing the current Regulations.
Installing the
Do not forget to remove the transit caps and
plugs from the boiler connections, these are
fitted to every boiler.
Keep the boiler clear of dust during
installation and in particular do not allow any
dust or debris to enter the top of the boiler
where the flue connection is made. It is
recommended that you put a dust sheet over
the top of the boiler until you are ready to
make the flue connection.
Remember to release the manual air vent
before filling the boiler. See the instructions
to identify the location of this device.
This boiler allows to
temperature of the central heating system at
very low levels.
In case of an underfloor heating system, a
temperature limiting device (e.g. a safety
thermostat) is recommended to stop the
boiler in case the water temperature exceeds
the design temperature.
You are strongly advised to flush out the
system both cold and hot in order to remove
system and installation debris.
When installing, commissioning or servicing a gas appliance that incorporates a pre-mix burner and zero-
set governor, because it is not possible to measure an operating pressure the engineer should first check
that the gas supply is metered and ascertain whether it is possible to measure the gas rate. If the gas input
rate can be measured then the requirements of GSUIR 26(9) can be met, including any specific
requirements in manufacturers' instructions.
If gas input rate cannot be measured then, to satisfy the intent of GSUIR 26(9), the engineer shall measure
the combustion quality of the appliance in accordance with BS 7967 or the manufacturers' instructions.
If the engineer does not have the required equipment and no alternative test is specified by the
manufacturer then the appliance shall be turned off and disconnected as an un-commissioned appliance
until such time that equipment is available to undertake such tests.

It is also sensible to initially
commission the boiler before connecting any
external controls such as a room thermostat.
By this method if you have a subsequent
problem following the addition of an external
control you can eliminate the boiler from your
fault analysis.
If the boiler is fitted with a digital
programmer, when setting the times for
automatic operation, remember that for
every "ON" time there must be an "OFF" time
to follow and that on every occasion you
enter a time you must also indicate which
days that you want the boiler to follow the
timed settings.
Some products incorporate an anti-cyclonic
time delay. It is normal when first switching
the boiler on for the boiler to operate on
heating for a few seconds then switch off.
After 3-4 minutes has elapsed the boiler will
then re-ignite and operate perfectly normally.
If you are in any doubts as to the installation
or operation of the boiler please read the
instruction manuals thoroughly and then if
necessary contact Biasi UK for advice and
assistance.
