Biasi ADVANCE OV Series User Manual And Installation Instructions page 6

You must ensure that you remove the transit caps and plugs from the boiler connections
which 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.
Please remember to remove all air from the heating system.
This boiler allows you to control the flow temperature of the central heating system at very
low levels. For underfloor heating system a temperature limiting device (e.g. a safety ther-
mostat) is recommended to stop the boiler in case that the water temperature exceeds
the design temperature.
You are strongly advised to flush out the system both hot and cold in order to remove any
system and installation debris to the British Standard BS 7593 code of practice.
It is also sensible to initially fire and commission the boiler before connecting any external
controls such as a room thermostat. By following this procedure, if you have a subse-
quent problem this method can eliminate the external controls from your fault analysis.
Some products incorporate an anti cycling 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 as-
sistance.
