5. Setup

1. Unpacking: Carefully remove the heater from its packaging. Retain packaging materials for future storage or transport.
2. Placement: Position the heater on a stable, level surface. Ensure there is at least 1 meter (3 feet) clearance from walls, furniture, curtains, and other combustible materials. Do not place the heater directly under a power outlet.
3. Ventilation: Always ensure the room has adequate ventilation. Open a window or door slightly to allow for fresh air circulation.
4. Gas Cylinder Connection:
   • Place the gas cylinder in the designated compartment at the rear of the heater.
   • Connect a compatible gas regulator and hose (not included) to the gas cylinder valve. Ensure the connection is tight and secure.
   • Connect the other end of the hose to the heater's gas inlet.
   • Leak Test: Before first use and after every cylinder change, perform a leak test. Apply a soapy water solution to all gas connections. If bubbles appear, there is a leak. Tighten connections or replace faulty parts. Never use an open flame to check for leaks.

6. Operating Instructions

1. Preparation: Ensure the gas cylinder valve is fully open.
2. Ignition:
   • Press and hold the control knob (refer to Figure 4.4) and turn it counter-clockwise to the ignition position (marked with a star symbol).
   • While holding the knob, repeatedly press the piezoelectric igniter button (usually a separate button or integrated into the knob) until the pilot flame ignites. You may hear a clicking sound.
   • Continue to hold the control knob for approximately 10-20 seconds after ignition to allow the thermocouple to heat up and activate the safety valve.
   • Release the control knob. If the flame extinguishes, repeat the ignition process.
3. Adjusting Heat Output: Once the pilot flame is stable, turn the control knob to select one of the three desired power levels (indicated by flame symbols on the knob).
4. Shutting Down: To turn off the heater, turn the control knob clockwise to the "0" (off) position. Close the gas cylinder valve.

7. Maintenance

• Cleaning: Ensure the heater is completely cool before cleaning. Use a soft, damp cloth to wipe the exterior surfaces. Do not use abrasive cleaners or solvents. Keep the air inlets and outlets clear of dust and debris.
• Gas Cylinder Replacement: Always ensure the heater is off and the gas cylinder valve is closed before replacing an empty cylinder. Follow the connection instructions in Section 5.
• Storage: When not in use for extended periods, disconnect the gas cylinder, clean the heater, and store it in a dry, well-ventilated area, away from direct sunlight and extreme temperatures.
