The discharge should terminate facing downward on the

xterior of the building in a position where discharging

(possibly boiling water & steam) will not create danger or

uisance, but in an easily visible position, and not cause

damage to electrical components and wiring.

The discharge must not be over an entrance or a window

or any other type of public access.

AIR RELEASE POINTS:

These m

ust be fitted at all high points where air naturally

collects and must be sited to facilitate complete filling of

the system.

The appliance has an integral sealed expansion vessel to

accommodate the increase of water volume when the

system is heated.

It can accept up to 7 litres (1.3 gal) of expansion water. If

the heating circuit has an unusually high water content,

an additional sealed expansion vessel must be fitted, for

GB refer to BS 7074 part 1 and for IE, refer to the current

edition of I.S. 813.

MAINS WATER FEED - CENTRAL HEATING:

A method for initially filling the heating system is supplied

with the connection kit. The filling loop is connected

between the cold water inlet and the central heating flow

connections, and incorporates a non-return valve. To

operate the filling loop, it is necessary to open both

quarter turn handles, once the required pressure has

been achieved, close both handles and disconnect the

hose in accordance with water byelaws. N

OTE: The

installer should ensure that there are no leaks as frequent

filling of the heating system can lead to premature scaling

of the main exchanger and failure of hydraulic

components.

DOMESTIC WATER:

The domestic water must be in accordance with the

relevant recommendation of BS 5546:1990. Copper

tubing to BS EN 1057:1996 is recommended for water

carrying pipe work and must be used for pipe work

carrying drinking water, a scale reducer should also be

used to reduce the risk of scale forming in the domestic

side of the heat exchanger.
