TECHNICAL SPECIFICATIONS
The manufacturer reserves the right to make any modifications it feels appropriate at any time.
INSTALLATION
Mounting to the wall
-remove the two self-threading screws from the bottom two corners of the front part (see
Figure 1);
- remove the front part slowly, by lifting it from below and pushing it upwards, and then
detaching it from the rear part;
- make four 6mm holes in the wall, following the indications shown in Figure 2;
-place the plastic plugs supplied in the holes;
- fasten the rear part to the wall using the 4 screws supplied;
- replace the front part, performing the same operations described previously in reverse
order.
FITTING THE FEET/WHEELS
-fasten the wheels and the feet to the holes shown in Figure 2, using the screws supplied.
IMPORTANT
The heater only works on natural gas at an inlet pressure of 18 mbar.
The adjustment and maintenance operations must only be performed by specialist personnel.
WARNING
The residues of combustion from the heater are discharged in the room, therefore sufficient ven-
tilation must be ensured.
For correct ventilation, the room that the appliance is used in must have an opening of at least
100 cm2. If necessary, this opening can be created by increasing the distance between the door
and the floor.
ON-OFF
Open the mains supply line cock.
Starting from position "0", fully press the adjustment knob and turn it anticlockwise, to position
"1". In this position, the pilot flame must ignite (if not, continue to press the knob for around 10
seconds so as to release any air in the pipes, and repeat the above operation).

Once the heater is on (as seen through the front grille), hold the knob in position "1"for
around 15 seconds, and then move it to the desired position.
To switch the heater off completely, turn the knob to position "0"and never forget to also close
the mains supply line cock.
IMPORTANT
The heater’s pilot flame also acts as an air analyser. This means that the device will completely
shut-off the flow of gas BEFORE the level of oxygen, due to combustion, in the room falls to
harmful levels for people. If this happens, open a window for a few minutes and adequately
ventilate the room. It will then be possible to ignite the heater again, ensuring adequate ventila-
tion in the room as described in the paragraph warning
When the heater is completely off, the mains supply line cock should also be closed.
MAINTENANCE AND CLEANING
- To perform any replacements and adjustments, always contact specialist personnel and
request the use of original spare parts.
- Clean the surfaces of the heater only when the appliance is cold, using a damp cloth.
Never use abrasive powders.
- Before igniting the heater again after the summer period, use a solution of soapy water to
check the seal of the fittings.
