2. Important Safety Information
Read and understand all safety warnings and instructions before operating this heater. Failure to comply may result in fire, explosion, carbon monoxide poisoning, property damage, personal injury, or death.
2.1 Carbon Monoxide Hazard
- This heater produces carbon monoxide, which is an odorless, colorless gas that can cause death.
- Use only in well-ventilated areas. Adequate ventilation must be provided.
- Never use this heater in living or sleeping areas.
- Install a carbon monoxide detector in any enclosed space where the heater is used.
2.2 Fire and Burn Hazard
- Keep combustible materials at least 10 feet (3 meters) from the front, sides, and top of the heater.
- Do not use this heater near gasoline, paint, or other flammable liquids and vapors.
- The heater surfaces become extremely hot during operation. Avoid contact.
- Ensure the heater is placed on a large, sturdy, level base to prevent tipping.
- The unit is equipped with an automatic overheat shutoff feature for enhanced safety.
2.3 Propane Gas Safety
- Use only liquid propane (LP) gas.
- Always connect the heater to an LP gas cylinder with the provided hose and regulator assembly.
- Check for gas leaks using a soap and water solution before each use. Bubbles indicate a leak. If a leak is detected, tighten the connection or replace the faulty part. Do not operate the heater if a leak is present.
- Store LP gas cylinders outdoors in a well-ventilated area, away from heat sources and direct sunlight.

5.1 Starting the Heater
- Ensure the heater is connected to a propane tank and all connections are secure and leak-free.
- Slowly open the main valve on the propane tank.
- Locate the control knob on the heater's base.
- Press and hold the red ignition button (piezo igniter) while simultaneously turning the control knob to the desired heat setting (Low, Medium, or High).

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater does not ignite | No propane flow; faulty igniter; air in gas line | Check propane tank level and valve; ensure gas line is purged; inspect igniter for damage. |
| Low heat output | Low propane pressure; control knob setting too low | Check propane tank for adequate pressure; adjust control knob to a higher setting. |
| Heater shuts off unexpectedly | Overheat protection activated; low oxygen sensor activated; low propane supply | Ensure proper ventilation; check propane supply; allow heater to cool down. |
