In the United Kingdom, the installation and initial start-up of the 
boiler must be by a Gas Safe 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. Gas Safe.
In the Republic of Ireland the installation and initial start-up of the 
appliance must be carried out by a Competent Person in accordance 
with the current edition of I.S.813 “Domestic Gas Installations” and the 
current Building Regulations, reference should also be made to the 
current ETCI rules for electrical installation.
The installation of this appliance must be in accordance with the 
relevant requirements of the Local Building Regulations, the current 
I.E.E. Wiring Regulations, the by-laws of the local authority, in Scotland, 
in accordance with the Building Standards (Scotland) Regulation and 
Health and Safety document No. 635, “Electricity at Work Regulations 
1989” and in the Republic of Ireland with the current edition of I.S. 813 
and the Local Building Regulations (IE).

Materials used in the manufacture of this appliance are non-hazardous 
and no special precautions are required when servicing.

Installation should also comply with the following British Standards 
Code of Practice:
BS 7593:1992  Treatment of water in domestic hot water central 

and in the Republic of Ireland in accordancce with the following 
codes of practice:

Avoid installing the boiler where the air inlet can be polluted by 
chemical products such as chlorine (swimming pool area), or ammonia 
(hair dresser), or alkalin products (launderette).

Flue
Detailed information on fl ue assembly can be found in the 
“Connecting the Flue” section.
The boiler must be installed so that the fl ue terminal is exposed to the 
free passage of external air at all times and must not be installed in 
a place likely to cause nuisance.  It must not be allowed to discharge 
into another room or space such as an outhouse or closed lean-to.
Condensing boilers have a tendency to form a plume of water vapour 
from the fl ue terminal due to the low temperature of the fl ue gasses.  
The terminal should therefore be located with due regard for the 
damage or discolouration that may occur to building within the 
vicinity and consideration must also be given to adjacent boundaries, 
openable windows the min acceptable clearances are shown 
opposite.

 N

It may be necessary to protect the terminal with a guard, if this is the 
case it will be necessary to purchase a stainless steel terminal guard.  
Reference should be made to the Building Regulations for guidance.

The room in which the boiler is installed does not require specifi c 
ventilation.  If the boiler is installed in a cupboard or compartment 
ventilation is not required for cooling purposes.

The gas installation and tightness testing must be in accordance with 
the requirements of BS6891.  Ensure that the pipe size is adequate for 
demand including other gas appliances on the same supply.

The appliance requires an earthed 230V - 50 Hz supply and must be in 
accordance with current I.E.E. regulations.  
It must also be possible to be able to completely isolate the appliance 
electrically.  
Connection should be via a 3 amp double pole fused isolating switch 
with contact separation of at least 3mm on both poles.  
Alternatively, a fused 3 amp, 3 pin plug and unswitched socket may be 
used, provided it is not used in a room containing a bath or shower, it. 
It should only supply the appliance.

The boiler is suitable for sealed systems only.  The maximum working 
pressure for the appliance is 6 bar.  All fi ttings and pipework for the 
appliance should be of the same standard.  If there is a possibility of 
the incoming mains pressure exceeding 6 bar, particularly at night, 
then a suitable pressure limiting valve must be fi tted.
The boiler is designed to provide hot water on demand to multiple 
outlets within the property.  If there is a requirement for greater 
demands, for example if the boiler has several bathrooms and 
cloakrooms, a vented or unvented hot water storage system may be 
used.

Any shower valves used with the appliance should be of a thermostatic 
or pressure balanced type.  
Refer to the shower manufacturer for performance guidance and 
suitability.
