2. Safety Instructions
Read all instructions carefully before using the heater. Failure to follow these instructions may result in fire, injury, or property damage.
- Ventilation: Ensure adequate ventilation in the greenhouse to prevent carbon monoxide buildup. Although paraffin heaters produce less CO than other fuels, proper airflow is crucial.
- Fuel: Use only high-quality paraffin oil specifically designed for heaters. Do not use gasoline, kerosene, or other flammable liquids.
- Placement: Place the heater on a stable, non-combustible surface, away from flammable materials such as curtains, plants, or plastic sheeting. Maintain a safe distance from walls and other objects.
- Refueling: Always turn off and allow the heater to cool completely before refueling. Refuel outdoors or in a well-ventilated area to avoid spills and fumes indoors.
- Children and Pets: Keep the heater out of reach of children and pets. Never leave an operating heater unattended.
- Fire Safety: Keep a fire extinguisher or sand readily available in case of fire.
- Inspection: Regularly inspect the wick and burner for wear or damage. Replace components as needed.

- Fuel Cap: For sealing the fuel tank.
4. Setup
Follow these steps to prepare your Warmax Power 4 heater for first use:
- Unpack: Carefully remove all components from the packaging.
- Placement: Position the heater on a flat, stable surface within your greenhouse, ensuring it is away from any combustible materials.
- Fill with Paraffin Oil: Unscrew the fuel cap. Using a funnel, slowly pour high-quality paraffin oil into the tank. Do not overfill. Ensure the wick is fully saturated before lighting (allow approximately 30 minutes for saturation).

5. Operating Instructions
Operating the Warmax Power 4 is straightforward:
- Wick Adjustment: Ensure the wick is extended slightly above the burner opening. Use the adjustment wheel to raise or lower the wick.
- Lighting the Wick: Carefully light the exposed wick with a long match or lighter.
- Flame Adjustment: After lighting, allow a few minutes for the flame to stabilize. Adjust the flame height using the adjustment wheel. A smaller flame provides less heat and extends burn time, while a larger flame provides more heat. Avoid excessively large flames, which can produce soot.
- Monitoring: Regularly check the heater's operation and the greenhouse temperature.
- Extinguishing: To turn off the heater, use the adjustment wheel to lower the wick completely into the burner assembly. The flame will extinguish. Ensure the flame is fully out before leaving the heater unattended.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your heater.
- Wick Care: Periodically trim the wick to remove any charred portions, which can improve burning efficiency and reduce soot. Replace the wick if it becomes too short or damaged.
- Cleaning: Keep the burner assembly and heat spreader clean from dust and debris. Use a soft cloth to wipe down the exterior.
- Fuel Tank: If storing the heater for an extended period, empty the fuel tank to prevent paraffin degradation.
- Storage: Store the heater in a cool, dry place when not in use.
7. Troubleshooting
Here are solutions to common issues you might encounter:
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater won't light | Wick not saturated; wick too low; no fuel; damaged wick | Allow wick to saturate; raise wick; refill tank; replace wick |
| Flame is weak or flickers | Low fuel; dirty wick; poor ventilation | Refill tank; trim or replace wick; ensure adequate ventilation |
| Excessive smoke or soot | Flame too high; dirty wick; incorrect fuel type | Lower flame; trim or replace wick; use only proper paraffin oil |
| Heater goes out unexpectedly | Lack of oxygen (poor ventilation); fuel tank empty | Improve ventilation; refill fuel tank |
