Safety notices
CAUTION
Danger of injury through sharp edges.
Handle the cladding panels with care and
avoid contact with sharp edges.

Requirements for boiler room
§
• Observe the local and national building reg-
ulations regarding boiler rooms.
• Observe the local and national regulations
regarding ventilation and deaeration of boil-
er rooms.
• Do not set up in very dusty rooms. If neces-
sary, use an external combustion air supply
and/or filter for the supply air.
• Gas boilers may not be installed in rooms
which may contain halogen compounds
which may combine with the combus-
tion air (e.g. laundry rooms, drying rooms,
workshops, hairdressing salon). Halogen
compounds may occur in, amongst oth-
ers, cleaning, de-greasing and solvent sub-
stances, adhesives and bleaching agents.
Always make sure that there is an adequate supply of
fresh air to the boiler room, to ensure that the combustion
air supply necessary for all the firing systems operated
can flow in without hindrance and that no oxygen defi
-
ciency occurs for the operating personnel.
The binding values for the size of intake air apertures
are not usually stated in the relevant regulations, it is laid
down only that the partial vacuum in the boiler room must
not exceed 3 N/m
2
. To comply with this requirement, an
air supply cross section of 500 cm
2
is to be provided up
to a nominal heat output of 1000 kW. With rectangular
apertures the side ratio is not to exceed 1.5 : 1 and an ap-
propriate supplement is to be made with grilles to ensure
that the free cross section reaches the above values.
In Austria the ÖNORM H 5171 additionally stipulates a
flue air aperture. This must have a minimum cross sec
-
tion of 180 cm
2
up to a nominal heat output of 100 kW.
The cross section is to be increased by 1 cm
2
for each
additionnal kW.
4.3
Flue gas connection, flue gas pipe,
dimensions of flue gas pipe
To guarantee economic and fault-free operation, boiler
and chimney must be mutually adapted to create a func-
tional unit.
NOTICE
Moisture-resistant and acid-proof chimneys
must be used for the CompactGas.
Renovation, respectively chimney cross section adjust-
ment may be necessary with existing chimney installa-
tions, according to the instructions of a chimney specialist.
The function of the chimney, i.e. the production of the
necessary delivery pressure is basically dependent on:
a)
he type (nature) of the chimney (thermal insu-
lation, interior surface roughness, sealing etc),
b)
the connection of the boiler to the chimney
according to specification,
c)
the correct chimney cross section
dimensioning.
§
The national regulations must be observed.
