Usage Features

Assembly and Initial Setup

  1. Remove Packing Materials: The grille needs to be opened to remove styrofoam packing wedges and the heat chamber assembly, which comes in protective packing.
  2. Replace Heat Chamber: After removing cardboard packing, the heat chamber assembly is replaced with its wire handle pointing to the front of the heater. The grille is then closed.
  3. Install Batteries: Two "D" size batteries are inserted into the battery holder located on the back of the heater, observing the correct polarity (+/-).
  4. Check Heat Chamber: Ensure the heat chamber is properly seated to prevent smoke and soot.

Fueling

  1. Access Fuel Tank: Open the fuel tank lid, lift out the removable fuel tank, turn it upside down, and remove the fuel tank cap.
  2. Siphon Kerosene: Insert the manual siphon's straight tube into a kerosene container and its flexible hose into the removable fuel tank opening.
  3. Start Flow: Turn the siphon's air vent knob clockwise to close the vent. Squeeze the siphon bulb vigorously 6-7 times to start the kerosene flow.
  4. Monitor Fuel Gauge: Watch the fuel gauge on the removable tank to avoid overfilling. Stop the flow by turning the air vent knob counterclockwise when the tank is half full.
    • Note: Overfilling, especially with cold kerosene, can cause overflow due to expansion when the fuel warms up.
  5. Secure Tank: Carefully remove the siphon, allow excess kerosene to drain, replace the fuel tank cap, and tighten it securely. Wipe away any spilled kerosene.
  6. Replace Tank: Invert the tank and place it back into the heater body.
    • Warning: Use only clean kerosene. Never use gasoline or other flammable liquids.

Lighting

  1. Level the Heater: The heater must be operated on a firm, level floor. Do not prop it up or place it on uneven surfaces.
  2. Engage Automatic Extinguisher: This is automatically engaged by turning the wick adjuster knob clockwise until it stops. If difficult, turn it counterclockwise once until it stops, then clockwise again.
  3. Wick Saturation: If fueling for the first time or after a long period without fuel, wait approximately 30 minutes for the wick to become fully saturated.
  4. First-Time Burn-in: For the first use, ignite the heater in a garage or well-protected outdoor area for about 15 minutes to burn off protective oil from burner parts. This prevents objectionable odors indoors.
  5. Automatic Lighting: Turn the wick adjuster knob clockwise until it stops. As the wick rises, the knob will turn with resistance and make a winding sound. Once the wick reaches its proper height, the automatic extinguisher engages. Gently push the igniter button; the igniter coil should glow and touch the wick.
    • Note: If the wick is difficult to ignite, slightly push back the igniter button to remove the coil from direct contact.
  6. Lighting with Match (if necessary): If automatic lighting fails (e.g., due to worn batteries or a defective igniter coil), open the grille, lift the heat chamber, and touch a match to the top of the wick. Do not let burned match parts fall onto the wick.
  7. Heat Chamber Seating: Ensure the heat chamber is properly seated by moving the wire handle left and right. Jerky movement indicates improper seating.

Adjusting the Flame

  1. Wait for Operating Temperature: After lighting, wait several minutes for the heat chamber to reach operating temperature and for the flame to become visible.
  2. Check Flame Height: After five minutes, the entire heat chamber should glow red.
    • Correct Flame: Most efficient combustion.
    • Too High: Produces smoke and soot.
    • Too Low: Produces odor.
  3. Adjust Wick: Raise or lower the wick by turning the wick adjuster knob to achieve the proper flame condition (uniform red glow from top to bottom of the heat chamber).
    • Note: Do not operate the heater with the wick set too low or too high, as this reduces combustion efficiency and increases unwanted emissions.
  4. Adjusting Maximum Wick Height (Wick Life Extender): If the flame length doesn't reach its normal level after prolonged use, the wick height needs adjustment using the wick life extender.
    • First, release the automatic extinguisher by pushing the manual shutoff button.
    • Pull the wick adjuster knob out completely.
    • The wick height adjuster knob has three holes (①, ②, ③) where a stem pin engages. Pull the control dial toward you and change the pin's location from ① to ②, or from ② to ③. Each step raises the maximum wick height by 2 mm.
    • Replace the wick adjuster knob.
    • Note: Only use positions ② or ③ when position ① no longer provides adequate flame length. When suitable flame length cannot be achieved even on position ③, the wick needs to be cleaned or replaced.

Extinguishing the Flame

  1. Routine Shutoff: Turn the wick adjuster knob counterclockwise until it stops (about a quarter turn). The flame will be completely extinguished, and the heater will be off.
    • Note: Do not use the automatic extinguisher for routine turn-off, as this can cause odor, smoke, and soot. The automatic extinguisher is for accidental jarring or tipping.
  2. Confirm Extinguishment: Ensure the flame is completely out.
  3. Relight Delay: Do not try to relight the heater for at least three minutes after extinguishing, as this may cause smoke and odor.

Manual Shutoff

  • For quick shutoff, push the manual shutoff button.
  • Note: For routine turn-off, only the wick adjuster knob should be used. Using the manual shutoff or activating the automatic extinguisher can cause unwanted odor, soot, and smoke.

Maintenance Features
