6 Boiler Location, Flue and Ventilation
6.1 Location
This boiler is not suitable for outdoor installation.
This boiler may be installed in any room, although particular
attention is drawn to the installation of a boiler in a room
containing a bath or shower where reference must be made to
the relevant requirements.
The boiler must NOT be installed in a cupboard.
In GB this is the current I.E.E. WIRING REGULATIONS and
BUILDING REGULATIONS.
In IE reference should be made to the current edition of I.S.813
"Domestic Gas Installations" and the current ETCI rules.
The boiler must be mounted on a flat wall, which is sufficiently
robust to take its weight, see diagram 1.1.
6.2 Clearances
The position of the boiler must be such that there is adequate
space for servicing.
The recommended clearances are shown in diagram 6.1.
The minimum acceptable spacings from the terminal to
obstructions and ventilation openings are shown in diagram
6.2. For Ireland the minimum distances for flue terminal
positioning must be those detailed in I.S.813 "Domestic Gas
Installations".
The terminal must be exposed to the external air, allowing free
passage of air across it at all times.
Being a condensing boiler some pluming may occur from the
flue outlet. This should be taken into consideration when
selecting the position for the terminal.
Carports or similar extensions of a roof only, or a roof and one
wall, require special consideration with respect to any openings,
doors, vents or windows under the roof. Care is required to
protect the roof if made of plastic sheeting. If the carport
comprises of a roof and two or more walls, seek advice from the
local gas supply company before installing the boiler.
