Installation and Servicing
SECTION 1 - GENERAL
1.9 FLUE INSTALLATION
Pluming will occur at the terminal so terminal positions where this could cause a nuisance should be avoided.
The flue must be installed in accordance with any local & state regulations and laws.
The following notes are intended for general guidance:
1.
The boiler MUST be installed so that the terminal is exposed to external air.
2. It is important that the position of the terminal allows the free passage of air across it at all times.
3. Minimum acceptable spacing from the terminal to obstructions and ventilation openings are specified in Table 4.
4. The flue assembly shall be so placed or shielded as to prevent ignition or damage to any part of any building.
IMPORTANT
. It is essential to ensure, in practice, that products of combustion discharging from the terminal cannot re-enter the
building or buildings through any openings into the building such as ventilators, windows, doors, or other sources of natural air
infiltration, such as forced ventilation openings etc.
If products of combustion re-entry is identified or suspected this should be immediately investigated and corrected following the
guidance provided by the local authority.

Prohibited area below electricity meter or fuse box extends to ground level.
Notes:
1. Where dimensions c, j
or k cannot be achieved
an equivalent horizontal
distance measured
diagonally from the nearest
discharge point of the
terminal to the opening may
be deemed by the Technical
Regulator to comply.
2. For minimum clearances
not addressed above
acceptance should be
obtained from the Technical
Regulator.
3. Minimum clearances d
and e also apply to any
combustion air intake
openings of appliances.
