Gas connection
■
The fresh air supply required
for trouble-free combustion
must be ensured. It is practical
to have the fresh air supply
provided by windows and
doors or through appropriately
dimensioned openings
in the outside wall
■
The units must not operate
continuously whilst unattended
The units may only be operated
in rooms if:
■
a sufficient quantity
ofair is supplied to the units for
the combustion
■
these are well ventilated and
aerated
■
the proportion of substances
harmful to health in the
breathing air is at a harmless
level
There is good natural ventilation
and aeration if:
1.
the room volume in m
3
is at least
30 times the nominal heating
capacity kW of all of the units
operating in the space, and
if the natural change of air is
guaranteed by windows and
doors or
2. constantly open ventilation
openings are present for
incoming and exhaust air
in the vicinity of the ceiling and
floor, whose size in m
2
is at least
0.003 times the nominal heating
capacity in kW of all of the units
operating in the space.
■
The use of longer hose lines
is permissible if:
- special operational reasons exist
- appropriate additional safety
measures are observed
and the hose lengths are kept
as short as possible
■
Hose lines must be
fundamentally protected
against chemical, thermal
and mechanical damage
■
The units may only be operated
out of the gas phase
■
The units must be serviced
by qualified persons only
■
Only original spare parts may
be used for repairs
■
Unit parts that are prone
to wear and ageing
(e.g. gas hoses) must be
replaced at regular intervals
The gas connection / unit
operation must take place
exclusively on the basis of
the accident prevention regulation
BGV D34, as well as the respective
local construction and fire
prevention regulations.
The units are operated with liquid
gas in accordance with DIN 51622.
They require a constant
unit
connection pressure of 1.5 bar.
It is prohibited to exceed or
undershoot the connection
pressure.
■
When using longer hose lines,
consider the respective pressure
loss
■
Only use components that have
been tested and are suitable for
the respective purpose, such
as gas hose, pressure controller
and hose breakage protection
or leak gas protection
■
If possible, the length of the gas
hose should not exceed 2 m
■
Only pressure controllers with
a fixed outlet pressure setting
are permitted. The units may
only be operated out of the gas
phase
CAUTION
The units must not be used
below ground level
, e.g.
in basements, without suitable
gas monitoring equipment.
CAUTION
The units must only be
installed in well ventilated
spaces and not in living areas
or similar recreational areas.
CAUTION
A constant unit connection
pressure of 1.5 bar (1500
mbar) must be guaranteed,
also in continuous operation.
NOTE
This does not apply
if the correct condition
is confirmed by an expert.
CAUTION
Before all work on the gas
supply and when replacing gas
cylinders, all shut-off valves
must be closed and no ignition
sources are permitted
in the immediate vicinity.
NOTE
It is prohibited to exceed
or undershoot the required
connection pressure.
