5 - MAINTENANCE
IMPORTANT! Regularly check with soapy water or equivalent means to ensure that the tubings, the
connections and the quickfit of the appliance (MODELS NOMAD and FIX) are LEAKPROOF.
Also check the connections to the gas cylinder or the gas installation for leaks.
Before carrying out maintenance operations, make sure the gas tap and/or the knob of the burner
are turned off.
- Maintenance comprises:
- Cleaning the outside of the heater (use a soft cloth and neutral detergents. Do not put any deter-
gent straight onto the parts that require cleaning).
- Inspecting or replacing the rubber hose (Lmax=1.5m), when damaged and at the intervals and
according to the methods provided for in the laws and regulations that are in force in the country in
which the heater is installed.
- Checking whether the parts of the quick coupling are still intact and cleaning these parts. Only use
original spare parts when replacing worn parts.
- Replacing the battery for the electronic ignition.
ALL other maintenance operations or alterations must be carried out by qualified fitters.
IMPORTANT! Regularly check the connections to the gas cylinder or the gas supply tube on leaks
with a soap solution or a similar product.
5.1 REPLACING THE GAS JET (Only to be carried out by qualified fitters)
1 – Remove the ignition/adjustment knob (1: Fig.12).
2 – Unscrew and lower the ring that supports the perforated bell that protects the burner’s inner
structure (2: Fig.12).
3 – Carefully lower the perforated bell + the steel cylinder.
4 – Find the gas jet (3: Fig. 12). Unscrew the gas jet from its housing under the venturi tube.
Replace it. BE SURE NOT TO DAMAGE THE THREADED PARTS when tightening the gas jet.
5 – Refit the cover and all the other parts you have previously removed.
6 - TROUBLESHOOTING
IMPOR
TANT! Before carrying out repairs, always TURN OFF the gas tap.
If there is no flame when the heater is switched on, this can be caused by:
1 – an insufficient gas flow (bad LPG gasification or filth in the installation), a blocked or faulty
pressure regulator.
2 – a sudden gust of wind (more than 3 m/sec.).
3 – a lack of gas (empty gas cylinder or interrupted gas supply) or a faulty pressure regulator.
4 – an interrupted thermocouple.
5 – a faulty electromagnetic valve.
6 – filth in the gas circuit.
7 - gas leaks.
