4. Setup and Installation

4.1 Unpacking

1. Carefully remove the heater from its packaging.
2. Remove all packing materials, including any protective films or ties.
3. Inspect the heater for any signs of damage. If damaged, do not use and contact your retailer.

4.2 Placement

• Place the heater on a firm, level, non-combustible surface.
• Ensure there is a minimum clearance of 1 meter (3 feet) from any combustible materials (e.g., curtains, furniture, walls).
• Do not place the heater directly under a power outlet.
• Ensure the room has adequate ventilation.

4.3 Gas Connection

This heater is designed to operate with Natural Gas. Ensure your gas supply is compatible.

1. Connect the gas supply hose to the heater's gas inlet. Ensure the connection is secure and leak-free.
2. Use only approved gas hoses and regulators that comply with local safety standards.
3. After connecting, perform a leak test using a soapy water solution on all connections. Bubbles indicate a leak. Tighten connections or replace faulty parts if leaks are detected.

5. Operating Instructions

5.1 Ignition

1. Ensure the gas supply valve is open.
2. Press and turn the control knob to the ignition position (usually marked with a spark symbol or 'MAX').
3. Hold the knob in for a few seconds to allow gas to flow to the pilot light.
4. While holding the knob, press the igniter button (if present) repeatedly until the pilot flame ignites. If there is no igniter button, a manual ignition method (e.g., long match or lighter) may be required.
5. Once the pilot flame is lit, continue to hold the control knob for 10-20 seconds to allow the thermocouple to heat up and activate the safety valve.
6. Release the control knob. The pilot flame should remain lit.
7. Turn the control knob to the desired heat setting. The main burner will ignite.
