3.1
STATUTORY REQUIREMENTS
GAS SAFETY (INST
ALLATION AND USE) CURRENT
REGULATIONS
The appliance is suitable only for installation in GB and IE and
should be installed in accordance with the rules in force.
In GB, a CORGI Registered Installer must carry out the installation.
It must be carried out in accordance with the relevant requirements
of the:
Gas Safety (Installation and Use) Regulations
The appr
opriate Building Regulations either The Building
Regulations, The Building Regulations (Scotland), Building
Regulations (Northern Ireland).
The W
ater Fitting Regulations or Water Byelaws in Scotland.
The Current I.E.E Wiring Regulations.
Wher
e no specific instructions are given, reference should be
made to the relevant British Standard code of Practice.
In Ireland (IE), the installation must be carried out by a Competent
Person and installed in accordance with the current edition of I.S.813
"Domestic Gas Installations", the current Building Regulations and
reference should be made to the current ETCI rules for electrical
installation.
It should also be in accordance with the relevant recommendations in
the current editions of the following British Standards and Codes of
Practice: BS 5449, BS 5546, BS 5440-1, BS 5440-2, BS 6798, BS
6891, Institute of Gas Engineer document IGE/UP-7, BS 7074
(expansion vessel) and I.S.813 for IE.
IMPOR
TANT NOTE:
Manufactur
er's instructions must NOT be
taken in any way as overriding statutory obligations.
3.3
FLUE TERMINAL POSITION
Detailed r
ecommendations for flue installation are given
in BS 5440-1. The following notes are for general
guidance.
a)
The appliance MUST be installed so that the ter
minal is exposed
to the external air.
b)
It is impor
tant that the position of the terminal allows free
passage of air across it at all times.
c)
It is ESSENTIAL TO ENSURE that pr
oducts of combustion
discharging from the terminal cannot re-enter the building or any
other adjacent building, through ventilators, windows, doors, other
sources of natural air infiltration, or forced ventilation/air
conditioning.
d)
The minimum acceptable dimensions fr
om the terminal to
obstructions and ventilation openings are specified in Figure 5.
e)
If the ter
minal discharges into a pathway or passageway check
that combustion products will not cause nuisance and that the
terminal will not obstruct the passageway.
f)
Wher
e the lowest part of the terminal is fitted less than 2000 mm
(78 in) above the ground, above a balcony or above a flat roof to
which people have access, the terminal MUST be protected by a
purpose designed K6 terminal guard (optional extra: Part No. 951507).
g)
The air inlet / flue outlet MUST NOT be closer than 25 mm (1 in)
to combustible material.
h)
Condensing appliances have a tendency to for
m a plume of
water vapour at the terminal under certain operating conditions. This
is normal but positions where this would cause damage or a
nuisance should be avoided. Consideration should be given to the
dispersal of the plume in terms of adjacent surfaces and
neighbouring properties. A special flue terminal, (Kit C), is available
to raise the flue discharge point; use of this terminal will limit the
maximum flue length available. For further information contact:
Halstead Boiler Ltd, Service Help Line: 01926 834834.
3.2
APPLIANCE LOCATION
The following limitations MUST be obser
ved when
siting the appliance:
a)
The appliance is not suitable for exter
nal installations. The
position selected for installation should be within the building,
unless otherwise protected by a suitable enclosure and MUST allow
adequate space for installation, servicing and operation of the
appliance and for air circulation around it (Section 2.4 and 3.4).
b)
This position MUST allow for a suitable flue system and ter
minal
position. The appliance must be installed on a flat vertical wall,
which is capable of supporting the weight of the appliance and
any ancillary equipment.
c)
If the appliance is to be fitted in a timber framed building it
should be fitted in accordance with the ‘Guide for Gas Installations
In Timber Frame Housing’, Institute of Gas Engineers document
IGE/UP-7. If in doubt, advice must be sought from the Local Gas
Supplier.
d)
The appliance is appr
oved to a protection rating of IP20.
Therefore if the appliance is to be installed in a room containing a
bath or a shower, any electrical switch or control utilising mains
electricity must be so situated that it cannot be touched by a person
using the bath or shower. Attention is drawn to the requirements of
the current BS 7671 (I.E.E Wiring Regulations) and in Scotland the
electrical provisions of the Building Regulations applicable in
Scotland.
3.4
VENTILATION REQUIREMENTS
Detailed r
ecommendations for air supply are given in BS 5440-2.
The following notes are for general guidance.
a)
It is not necessar
y to have a purpose provided air vent in the
room or internal space in which a room-sealed appliance is
installed.
b)
Cupboar
d or compartment ventilation is not necessary for a
room-sealed appliance providing that the minimum clearances are
maintained.
c)
Wher
e an open flued, (B23), system is used, then an air vent
must be provided in the same room or internal space as the flue
duct air inlet, with a minimum free-area of at least:
