External wiring must be correctly earthed, polarised and in accordance with relevant

regulations / rules. In GB this is the current I.E.E. WIRING REGULATIONS. In IE

reference should be made to the current edition of the ETCI rules. This boiler is

supplied for connection to a 220 - 240 V~ 50 Hz supply.

The supply must be fused at 3 A.

The method of connection to the electricity supply must facilitate complete electrical

isolation of the appliance, by the use of a fused double pole isolator having a contact

separation of at least 3 mm in all poles or alternatively, by means of a 3 A fused

three pin plug and unswitched shuttered socket outlet both complying with BS 1363.

The point of connection to the Electricity supply must be readily accessible and

adjacent to the appliance unless the appliance is installed in a bathroom when this

ORK

Copper tubing to BS EN 1057:1996 is recommended for water pipes.

Jointing should be either with capillary soldered or compression fittings.

Where possible pipes should have a gradient to ensure air is carried

naturally to air release points and water flows naturally to drain taps.

The appliance has a built-in automatic air release valve, however it

should be ensured as far as possible that the appliance heat exchanger

is not a natural collecting point for air.

Except where providing useful heat, pipes should be insulated to prevent

heat loss and avoid freezing.

Particular attention should be paid to pipes passing through ventilated

spaces in roofs and under floors.
