Gas Safety

The Smell of Gas

Gas contains an odorant to make leaks detectable by smell. Gas is heavier than air, so try to smell for it near the floor.

Immediate Actions for Gas Smell:

• Immediately shut off the gas supply.
• Avoid creating sparks or fire. Do not switch electricity on/off, light matches/lighters, or use your telephone.
• Evacuate the area around the gas source and ensure good ventilation for the gas to dissipate. Stay clear of the area. If gas smell persists or you are unsure, contact the fire department.
• Gas leaks must be repaired by qualified personnel only.

Operation

1. Check the heater for damage or defects. Do not use a damaged heater; contact your supplier.
2. Ensure you use undamaged, full gas bottles with propane or butane.
3. Select a location that meets all safety instructions. Place the heater on a level, stable, horizontal surface made of non-flammable material. Do not plug it in and set the power switch to O (off).
4. Firmly attach the gas hose to the pressure regulator using suitable tools (left screw threads).
5. Remove the protective cap and attach the gas supply hose to the device (left screw threads). Screw the nut firmly for a secure connection.
6. Connect the pressure regulator to the gas bottle. Screw the nut firmly to prevent gas leakage. Ensure the gas hose is not bent or kinked, and avoid twisted or pulled tension.
7. Verify the device is correctly attached to the gas bottle and perform a complete gas leakage test as described below.
8. Once confirmed, open the gas tap (Diagram 1).
9. Insert the plug into the socket and set the power switch to I (on) (Diagram 2). The fan will start.
10. Wait for the fan to run steadily. Press the gas valve button with your right hand for 10 seconds while simultaneously pressing the ignition button several times with your left hand to ignite the device (Diagram 3).
11. Once the gas ignites, keep the gas valve pressed for another 15 seconds. Then release; the gas will burn continuously (Diagram 4).
12. To switch off, close the gas tap on the gas bottle and wait for the flame to extinguish. Set the power switch to O (off) and unplug the unit. Disconnect the pressure regulator from the gas bottle.

Attention: The device remains hot for a while after use. Always unplug when not in use.

If changing the gas bottle or reusing after storage, repeat the entire process, including the gas leakage test.

Attention: If the device fails to ignite after three attempts, do not try again due to explosion risk from gas concentration. Contact your dealer to diagnose the malfunction. Ensure the gas hose is not bent or kinked, and avoid stress that could cause damage or leaks. Always use the correct, supplier-provided regulator and hose. A 1.5-meter hose is recommended.

Gas Leakage Test

Perform a complete gas leakage test during installation, after changing a gas bottle, and after storage to rule out damage. Use a soap solution (1 part liquid soap, 1 part water) for testing. Never use an open flame. Do not smoke during tests. If a leak is detected, immediately close the gas tap, move the equipment away from heat/sparks, and contact your supplier. Perform the test with a full gas bottle.

• Unplug the unit, switch the power switch to O (off), and close the gas supply.
• Prepare a 1:1 soap and water solution.
• Apply the solution to the entire gas transport system, especially connections, using a spray bottle, brush, or cloth.
• Open the gas supply. Soap bubbles will indicate a leak.
• If a leak is found, shut off the gas supply, tighten the leaking part, turn the gas supply back on, and re-check. Contact your dealer if bubbles reappear.
• Ensure no fire or sparks are present during the test and do not smoke.
• If the gas hose shows signs of damage (bursting, cracks, wear, burns), replace it with an equivalent hose of the same length. Replace the hose at least every 3-4 years, or sooner if damaged. Use only approved hoses.

Cleaning and Maintenance

Switch off the unit, unplug it, and allow the heater to cool before cleaning or maintenance.

Keep the unit clean, especially grills and fan blades, by regularly removing dust. Clean the housing with a damp cloth; avoid aggressive, corrosive, or abrasive cleaning agents. Dust and dirt can be removed with a brush, vacuum, or compressed air.

Check the flame after ignition. A normal flame is blue, stable, and uniform. If not, contact customer service.

Regularly check the gas hose and screw connections. Replace damaged hoses immediately. Replace hoses at least every 3-4 years, even if no visible damage is present. Use only approved hoses.

If the gas tap on the bottle falters, switch off the power, unplug the unit, and let it cool. The gas valve will block the supply. Do not disconnect the hose. Take the bottle and device to your gas supplier. This issue is not with the unit itself.

For long-term storage, disconnect the gas supply hose, place the protective cap on the opening, and store the unit in its original packaging or a dust-free box in a cool, dry place, out of reach of children. Before reuse, check the fan and ensure no flammable materials are near the heater. Perform a gas leakage test.

Repairs must be done by qualified personnel using only original parts, including hoses and regulators. The heater requires annual inspection by a qualified person.
