3.1 Flue Options
There are various flue options to choose from as illustrated in
diagram 3.3. The flue lengths and installation of various flue
types are described in section 10.
3.2 Flue Terminal Position
The minimum acceptable siting dimensions for the terminal
from obstructions, other terminals and ventilation openings
are shown in diagram 3.1. 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.
NOTE: If necessary it is permitted to increase the terminal
protrusion through the outside wall to greater than the
minimum dimension of 87mm but no more than 600mm.
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.

H* and J* See diagram 3.1 . These dimensions comply with
300
the building regulations, but they may need to be increased
to avoid wall staining and nuisance from pluming depending
300
on site conditions.

3.3 Terminal Guard
25
25
A terminal guard is required if persons could come into
contact with the terminal or the terminal could be subject to
300
damage.
If a terminal guard is required, it must be positioned to
300
provide minimum of 50mm clearance from any part of the
terminal and be central over the terminal.
600
The guard should be similar to that shown in diagram 3.2.
