VENTILATION NOTICE

• Please be aware that your heater consumes oxygen during operation. To ensure safe use, it’s crucial to have proper ventilation in the room where the heater is used. This facilitates the removal of combustion by-products and allows fresh air to enter.
• Appropriate ventilation significantly lowers the risk of condensation. Refer to the table below for the recommended room sizes for each heat setting and the corresponding required ventilation surface.

REQUIRED VOLUME OF ROOM AND VENTILATION SURFACE

CONNECTING THE CONTAINER

Gas Connection Guidelines
Utilize an approved regulator that matches the gas supply pressure, along with an approved tubing. The tubing should be no shorter than 50cm and under no circumstances longer than 1m. During the connection process, take care to avoid any twisting of the hose.

Gas Leak Testing

1. Turn all appliance control knobs to the “OFF” position.
2. Be sure that the gas regulator is tightly connected to the gas cylinder.
3. Turn on the gas valve. If you hear a rushing sound, turn the gas off immediately. There is a major leak at the connection. Connect properly before proceeding.
4. Brush soapy solution (mixture of half soap and half water) onto hose connections.
5. If growing bubbles appear, there is a leak. Turn the gas valve of the cylinder off immediately and check the tightness of all the connections. If the leak cannot be stopped, do not try to repair it and reach out to the after-sales service team.
