6. INSTALLATION

6.1

Reference Standards

The technical information and instructions provided herein below
are  intended for  the installer / Ser vicing Technician  so that the
unit may be installed and serviced correctly and safely.

In the United Kingdom the installation and initial star t up of the
boiler  must  be b y  a CORGI Registered Installer in accordance
with the installation standards currently in eff ect, as well as with
any and all local health and safety standards i.e. CORGI.

In the Republic of Ireland the installation and initial start up of the
appliance must be carried out by a Competent Person in accor-
dance  with the current edition of I.S

.813  “Domestic  Gas

Installations”, the current Building Regulations , reference should
also be made to the current ETCI rules for electrical installation.

This appliance must be installed by a competent installer in
accordance  with current Gas Saf ety  (installation & use)
Regulations.

The installation of this appliance m ust be in accordance with the
relevant requirements of the Local Building Regulations , the cur-
rent  I.E.E. Wiring  Regulations,  the b ylaws  of the local w ater
authority, in Scotland, in accordance with the Building Standards
(Scotland) Regulation and Health and Saf ety document No. 635
“Electricity  at w ork  regulations 1989” and  in the Repub lic  of
Ireland  with the current edition of I.S . 813,  the Local Building
Regulations (IE).

C.O.S.H.H.

Materials used in the manufacture of this appliance are non-haz-
ardous and no special precautions are required when ser vicing.
Installation should also comply with the following British Standard
Codes of Practice

The  appliance ma y  be installed in an y  room or indoor area,
although particular attention is dr awn to the requirements of the
current I.E.E. Wiring Regulations, and in Scotland, the electr ical
provisions  of the Building Regulations applicab le  in Scotland,
with  respect to the installation of the combined appliance in a
room containing a bath or sho wer, the location of the boiler in a
room containing a bath or sho wer should only be considered if
there is no alternative.

Where a room-sealed appliance is installed in a r oom con-
taining  a bath or sho wer  the appliance and an y  electrical
switch  or appliance contr ol, utilising  mains electricity
should be situated so that it cannot be touc hed by a person
using  the bath or sho wer, specifically  in accor dance  with
current IEE Wiring Regulations.

The  location m ust  permit  adequate space f or  servicing  and air
circulation around the appliance as indicated in Section 6.4.
The location must permit the provision of an adequate flue and
termination.
For unusual locations special procedures may be necessary.
BS 6798-1987 gives detailed guidance on this aspect.
A compartment used to enclose the appliance must be designed
specifically for this purpose. No specific ventilation requirements
are needed for the installation within a cupboard.
This appliance is not suitable for outdoor installation.

The type C appliances (in whic h the combustion circuit, air
vent  intake and comb ustion  chamber  are air -tight  with
respect to the room in which the appliance is installed) can
be installed in any type of room.

Secondary ventilation is not required with this boiler . The boiler
must be installed on a solid, non-comb ustible, permanent wall to
prevent access from the rear.
