Flue Terminal Location
5851 670
Detailed recommendations for flue
installation are given in BS 5440:1.
The following notes are for general
guidance.
The boiler must be installed so that
the terminal is exposed to external
air.
& It is important that the position of the
terminal allows free passage of air
across it at all times.
&
19
Montagevorbereitung
Montagevorbereitung (Fortsetzung)
It is essential to ensure that products of combustion discharging
from the terminal cannot re-enter
the building or any other adjacent
building, through ventilators,
windows, doors, other sources of
natural air infiltration or forced ventilation / air conditioning.
& The minimum acceptable dimensions from the terminal to obstructions and ventilation openings are
specified in on page 16(BS 5440
Part 1).
& If the terminal discharges into a
pathway or passageway check that
combustion products will not cause
nuisance and that the terminal will
not obstruct the passageway.
&
Where the lowest part of the terminal is fitted less than 2 m above
ground, above a balcony or above a
flat roof to which people have
access, the terminal must be protected by a purpose designed guard.
(Available as an optional extra).
& Where the terminal is fitted within
850 mm of a plastic or painted gutter, or 450 mm of painted eaves, an
aluminium shield, at least 750 mm
long, must be fitted to the underside
of the painted surface.
& The air inlet / flue outlet duct must
not be closer than 25 mm to combustible material.
& Due to the high efficiency of the boiler the terminal may emit a plume of
vapour. This is normal but positions
where this would cause a nuisance
should be avoided.
&
Ventilation Requirements
Detailed recommendations for air
supply are given in BS 5440:2. The
following notes are for general guidance.
It is not necessary to have a purpose provided air vent in the room
or internal space in which the appliance is installed.
& If the boiler is to be installed in a
cupboard or compartment, no permanent air vents are required for
cooling purposes in the cupboard or
compartment, however, it is essential to ensure that the minimum clearances stated in page 9 are
maintained.
&
Central Heating System (typical system designs)
The Vitodens 100 is designed for connection to sealed central heating water
systems.
& A sealed system must only be filled by a competent person.
