that you put a dust sheet over the top of the boiler until you are ready to make the flue
connection.
Because every boiler is fired and tested live at the factory, a small amount of water re-
mains within the boiler. It is possible for this water to initially cause the pump to seize. It is
therefore recommended that the pump rotor be manually turned to free its rotation before
turning the boiler on.
Remember to release the auto air purge before filling the boiler. See the instructions to
identify the location of this device.
This boiler allows to control the flow temperature of the central heating system at very
low levels. In case of underfloor heating system a temperature limiting device (e.g. a
safety thermostat) 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 cold and hot to the British Standard
BS 7593-2006 Code of practice, in order to remove system and installation debris.
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 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 opera-
tion, 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 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. The igni-
tion delay cycle does not prevent normal operation of the boiler to provide d.h.w.
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.
