2.5 Ventilationskrav

When operating the heater indoors, ensure adequate ventilation. The heater requires a minimum vent area of 9 square inches (example: 3" x 3" opening) at the ceiling and at floor level for adequate ventilation during operation. Do not use other fuel burning appliances inside the enclosure with a window or roof vent.

2.6 Brændstoftype

Use only propane (LP) gas. Never use refillable propane cylinders with this heater. Only use disposable 1lb propane cylinders or connect to a larger propane tank using an approved adapter hose (sold separately).

4.1 Justering af varmeindstillinger

1. Once the pilot light is stable, turn the control knob to your desired heat setting: "LO" (Low) for 4,000 BTU or "HI" (High) for 9,000 BTU.
2. Allow the ceramic burner to fully glow orange (approximately 30 seconds) before adjusting the setting further or leaving the heater unattended.
3. The heater is designed to be noiseless during operation.

4.2 Brændstofforbrug

A 1lb propane cylinder typically provides approximately 5.4 hours of heat on the "LO" setting and 2.4 hours on the "HI" setting.

5. Vedligeholdelse

Regelmæssig vedligeholdelse sikrer varmeapparatets levetid og sikre drift.

• Keep the heater clean and free from dust and debris.
• Periodically inspect the burner and pilot assembly for any blockages or damage.
• Ensure the safety screens are intact and free from damage.

6. Fejlfinding

If your heater is not operating correctly, refer to the following common issues:

• Heater does not light: Ensure propane cylinder is connected correctly and has fuel. Check for gas flow.
• Pilot light does not stay lit: Ensure the control knob was held down for the recommended 30 seconds after ignition. Check for proper alignment of the pilot.
• Propane tank freezes over: This can occur in cold temperatures during prolonged use. Allow the tank to warm up or switch to a fresh tank.
• Varmeapparatet slukker uventet: This is likely due to the ODS or tip-over safety systems activating. Ensure adequate ventilation and that the heater is on a stable, level surface.
