BEFORE FITTING THIS BOILER THE
INSTALLER MUST CHECK:
1.
What the maximum hot water demand is likely to be placed on
the boiler. Not every installation is suitable for a Combi boiler.
Systems requiring very high hot water flow rates may be better
suited with an unvented cylinder.
2.
That the mains are capable of supplying up to 24 litre/min with a
minimum dynamic pressure of 1.8 bar at the boiler. This is to
ensure that the boiler can achieve its maximum output.
3.
The hardness of the mains water supply. Systems with hard water
must be fitted with a suitable chemical scale preventer (eg Fernox
Quantomat or Combimate alternatively contact Warmflow for
further details).
4.
That the flow from any one hot water outlet does not exceed the
maximum recommended. This applies particularly to baths which
are usually fitted with larger taps and larger bore supply pipes. It
may be necessary to restrict the flow to these taps by reducing
the bore of the supply pipework or by fitting a restrictor into the
pipework.
5.
That any outlet when opened does not starve all the other outlets
of hot water. If more than one outlet is open at the same time
then the total flow from all the outlets should not exceed the
maximum flow rate of the boiler.
6.
That any showers being supplied hot water by the boiler are
compatible with this type of appliance.
It should be noted that the boiler has been factory fitted with
an 18 litre/min flow restrictor.
The manufacturers guarantees are void if the appliance is
not installed and commissioned in accordance with the
recommendations made herein.
