Figure 1: Mr. Heater F242300 Propane Infrared Heater/Cooker. This image shows the heater unit with its radiant dish and protective grill, mounted on a metal stand, and connected to a green 1-pound propane cylinder. The control valve is visible at the top of the cylinder connection.
Setup
- Unpack the Unit: Carefully remove the heater and its components from the packaging. Inspect for any damage.
- Attach Propane Cylinder: Ensure the heater's control knob is in the 'OFF' position. Thread a 14.1-16.4 oz. disposable propane cylinder (not included) onto the heater's regulator connection. Hand-tighten only. Do not overtighten.
- Position the Stand: The unit comes with a stand that allows it to be used in two positions:
- Heater Mode: Position the unit upright so the radiant dish faces forward, directing heat horizontally.
- Stove Mode: Lay the unit down so the radiant dish faces upwards, allowing a pot or kettle to be placed on the grill for cooking.
- Optional 20-lb Tank Connection: For extended use, the heater can be connected to a 20-pound propane tank using an optional hose (sold separately). Follow the hose manufacturer's instructions for proper connection.
Operating Instructions
- Ensure Proper Ventilation: Always operate the heater in a well-ventilated outdoor area.
- Ignition: Slowly turn the control knob to the 'LOW' position. Use a long-stem lighter or match to ignite the burner. Once ignited, hold the knob in for a few seconds to engage the thermocouple.
- Adjust Heat Output: Rotate the control knob to select your desired heat setting: 'LOW' (8,000 BTU), 'MEDIUM' (12,000 BTU), or 'HIGH' (14,000-15,000 BTU).
- Using as a Heater: In the upright position, the unit provides radiant heat for warming outdoor spaces.
- Using as a Stove: In the horizontal position, the upward-facing radiant dish can be used to heat water or cook food. Place cookware directly on the protective grill.
- Estimated Run Time: A 1-pound propane cylinder typically lasts approximately 2 hours on the 'LOW' setting and less on 'HIGH'.
- Shutting Down: Turn the control knob to the 'OFF' position. Allow the unit to cool completely before handling or storing.
Maintenance
- Cleaning: Allow the heater to cool completely. Wipe exterior surfaces with a damp cloth. Do not use abrasive cleaners or solvents. Keep the radiant surface and grill free of debris.
- Inspection: Regularly inspect the propane cylinder connection for leaks (use a soapy water solution; bubbles indicate a leak). Check the hose (if used) for cracks or damage.
- Storage: Disconnect the propane cylinder when the heater is not in use. Store the heater in a cool, dry place away from direct sunlight and heat sources. Do not store propane cylinders indoors.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater does not ignite. | No propane flow, empty cylinder, faulty igniter. | Check propane cylinder connection. Replace empty cylinder. Ensure control knob is fully open. |
| Low heat output. | Low propane level, partially closed valve, cold cylinder. | Replace cylinder. Ensure valve is fully open. Allow cylinder to warm slightly (do not heat directly). |
| Flame goes out after ignition. | Thermocouple not engaged, strong wind. | Hold control knob in longer after ignition. Shield unit from strong winds. |
