Important Installation Hint
When the gas hose is installed or removed make sure
to counteract at the gas connection nipple of the unit
(according to DIN 4815, part 2) by means of an open-
ended spanner SW 19, whereby the left-handed thread
is to be taken into account.
Hint!
Insufficiently dimensioned supply plants can cause icing
of the pressure gas or pressure reservoirs.
When the gas pressure falls, a proper gas supply to the
consumer points can no longer be ensured in many
cases.
This will result in imperfect combustion, harmful waste
gases or extinction of the flame. Therefore the supply
plant is to be dimensioned in such a way as to ensure
that problems of this kind cannot be caused.
The cristalline white frost may not be removed by open
fire, glowing objects or radiators. Sufficient gas supply to
the consumer points can be ensured by using an evapo-
rator.
Sufficient gas supply is to be ensured according to the
unit power rating (see identification plate), service life
and ambient temperature of the supply tanks.
In principle, we recommend that you use a set of at
least 3 cylinders to avoid intensive icing of the reser-
voirs.
The number of cylinders can be increased by using a
set of several cylinders (accessories), depending on the
unit capacity and the service life.
This procedure is to be carried out also for all further
gas components, such as pressure controller, hose
shearing pin, etc.
When any work is carried out on the gas supply
line and when the gas cylinder is replaced, all
stop valves must be closed and there may be
no ignition sources in the direct surroundings.
Multi - cylinder Set
Important!
The pressure gas tanks are to be installed laterally
behind the unit. The tanks may never be heated and
defrosted, respectively by the unit's hot air current
(danger of explosion!)
Cylinders with liquid gas may never be used in a lying
position when the unit is in operation (gas leakage in the
liquid phase).
All cylinder valves are to be opened to ensure regular
gas tapping.

Tank Gas Plants
When the units are connected to tank gas plants, make
sure that the pipes are properly dimensioned according
to the conduit length.
We recommend that a permanently set pressure
controller with an outlet pressure of 1.5 bar and an
appropriate gas throughput (please refer to unit type
plate) is installed directly beside the unit, as well as a
certified stop valve which has been adapted to the
admission pressure concerned, to ensure a perfect
function of the unit.
It has proven that the installation of a gas filter in front of
the control and safety devices of the units is absolutely
necessary (please also refer to DIN 4788 and TRF 88,
section 5), to avoid operating troubles of the control and
safety devices of the unit which can be caused by
harmful substances such as rust and dust from the gas
supply line (or tank).
