2) The machine performance is not optimal, thus
lengthening drying times.
We must remind of the daily frequency of these operations,
which can be performed directly by the operator.
5.4.4 FLAME QUALITY
The flame must be taught and light blue. If it is irregular
and yellowish, the appliance requires an intervention by the
installation technician.
Periodic control by qualified staff.
ATTENTION!
The general checks to be made on the appliance remain
valid in all cases.
However, if one of the following cases occurs, call the after-
sales assistance immediately.
1) When soot, dirt or stains are identified in the appliance
or in the immediate vicinity, due for example to
possible burning.
2) If the flame is not blue and taught.
3) When strange noises are heard on ignition.
4) If the gate valve on the supply line does not function
correctly, e.g. if the machine supply does not close
hermetically.
5) If there is the repeated intervention of safety devices
such as alarms E4, E5, E9 or the TSR manual rearm
thermostat.
5.4.5 WHAT TO DO IF YOU SMELL GAS
Considering that all combustible gases must have a
characteristic odour, in a way to be able to detect the
presence, in the case of leaks, before reaching dangerous
levels. If this characteristic odour is detected act as follows:
1) Open doors and windows to air the room as much as
possible.
2) Switch all flames off immediately.
3) Close the gate valve or the main supply valve of the
appliance or appliances.
4) Do not smoke or ignite naked flames.
5) Do not activate any type of electrical appliance or
telephone.
6) Keeping the main gate valve closed, check that other
secondary gate valves are also closed.
Remember that if the gas is powered by G30 or G31 liquid
gas (commonly called GPL or LPG), as this is heavier than air,
accidental leakage tends to initially fall to the ground and so
it must be “brushed” away to remove the gas residues.
In all cases, call the after-sales service immediately. The gas
leak will be eliminated and the tightness of the new supply
network will be inspected.
5.4.6 INSTRUCTIONS FOR MODIFYING THE CALIBRATION
OF THE DRYER FOR OTHER TYPES OF GAS.
Replace the nozzle placed on the right of the burner checking
that the diameter stated in the new nozzle that is to be
mounted corresponds to the following table (see exploded
diagram-gas battery page).

If gas heating appliances are installed in Belgium or France,
as well as mounting the nozzle a diaphragm must also be
mounted as described in chapter 1.4.7.2.
As well as modifications of the nozzle and the diaphragm the
identification plate positioned on the rear of the appliance
and the last page of this manual must also be updated. The
positioning of the adhesives stating the new features must
entirely cover the original indications so as not to cause any
misunderstandings.
5.4.7 ADJUSTMENT AND ADAPTATION OF THE VALVE
5.4.7.1 Gas pressure adjustment to the valve.
Premise: this operation must only be performed by a
qualified technician.
Close the gas network gate valve and switch the machine
off.
Remove the upper, rear panel of the machine via the
screws.
Access is now given to the compartment where the gas
heating battery is mounted. The gas control electrovalve is
fixed on the right of the battery, similar to that indicated in
the figure. Proceed as follows to vary the machine supply
pressure.
1. Loosen the safety screws that close the attachment for
the manometer downstream from the valve (see figure
2 reference 1).
2. Connect a manometer to the attachment just opened.
3. Check the correct supply pressure of the valve, the
type of gas and the diameter of the nozzle installed.
4. Remove the aluminium safety screw (see figure
2 reference 3) which hides a plastic screw for the
adjustment of the gas pressure downstream from the
electrovalve.
5. Open the gas supply gate valve and switch the machine
on.
6. During ignition of the burner, adjust the pressure
indicated on the manometer to obtain the desired value
(see table showing the necessary values for every type
of gas in paragraph 1.4.5). To adjust, slowly turn the
plastic screws (see figure 2 reference 3) clockwise to
