2.3 Terminal Position
The minimum acceptable siting dimensions for the terminal
from obstructions, other terminals and ventilation openings are
shown in diagram 2.5. 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.
It may be necessary to increase dimensions H & J if there is a
risk that the boiler products could stain any adjoining surface.
Increased siting flexibility can be achieved by using the Glow-
worm Plume Management Kit .
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, see diagram 1.1.
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 2.5 . These dimensions comply with
the building regulations, but they may need to be increased to
avoid wall staining and nuisance from pluming depending on
site conditions.
Plume Management Kit can be used to overcome many site
issues.

2.4 Terminal Guard

A terminal guard is required if persons could come into contact
with the terminal or the terminal could be subject to damage.
If a terminal guard is required, it must be positioned to provide
minimum of 50mm clearance from any part of the terminal and
be central over the terminal.
The guard should be similar to that shown in diagram 2.6.
