3.1 Reference Standards

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 effect, 
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 
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).

C.O.S.H.H.

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

I.S. 813   

Domestic Gas Installations

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).

3.1.1 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 should also 
be taken into consideration when siting the fl ue.

The minimum acceptable clearances are shown below:

 - A Directly below an opening, window, etc 

300 mm

- B Horizontally to an opening, window, etc 

300 mm

- C Below gutters, soils pipes or drain pipes 

75 mm

- D Below eaves 

200 mm

- E From vertical drain pipe or soil pipe 

75 mm

- F From internal or external corner 

300 mm

- G Above ground, roof or balcony level 

300 mm

- H From a surface facing the terminal 

600 mm

- I   From a terminal facing a terminal 

1200 mm

- J  Vertically from a terminal on the same wall 

1500 mm

- K Horizontally from an terminal on the same wall 300 mm
- L Fixed by vertical fl ue terminal

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.

3.1.2 Ventilation

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.
