4.8.9

Installation to an existing central heating

system

The System boiler is designed to operate
on a sealed system only. Therefore if the
existing system is of the open water type it
will have to be modified to comply with BS

5376 Part 2.
Before installing a new System boiler to an

existing system, flush out the old system
with a recommended descaling agent.

It is most important that the correct concen-

tration of the water treatment product is

maintained in accordance with the manu-

facturers’ instructions.

If the boiler is installed in an existing system

any unsuitable additives MUST be removed
by thorough cleansing.

BS 7593:1992 details the steps necessary

to clean domestic central heating system.
Also check pipework and renew any corrod-
ed pipework or fittings. Valve glands must
be repacked or replaced wherever neces-
sary and any defective controls exchanged.

WATER TREATMENT

This boiler has a secondary ALUMINIUM
alloy heat exchanger Ravenheat recom-

mended only the use of FERNOX-COPAL,

SENTINEL Xl00 or SALAMANDER CUR-

ROSION GUARD water treatment products,

which must be used in accordance with the
manufacturers instructions. For further
information contact:

ELECTRICAL SUPPLY

Warning: this appliance must be earthed

4.10.1

External wiring to the appliance must be

carried out by a competent person and be in
accordance with the current I.E.E. Regula-

tions and local regulations which apply.
The Ravenheat boiler is supplied for con-

nection to a 230 V - 50 Hz single phase

supply.

The supply must be fused at 3 A.

NOTE: 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. The point of connection to the elec-

tricity supply must be readily accessible and

adjacent to the appliance except, where the
appliance is installed in a bathroom, this

MUST be sited outside the bathroom.

SECTION

5 INSTALLATION

5.1

WARNING

5.1.1

It is MOST IMPORTANT that this appliance

is installed in a VERTICAL POSITION, with

the flue air duct passing through the wall.

Make sure flue slopes 2.5

o

down towards

the boiler that is 45 mm/m fall per metre
of flue length.
