AW4E / #4E Heater Replacement Wick - Pack of 2

Key Features

• High-Temperature Fiberglass Top: The upper portion is constructed from premium heat-resistant fiberglass that won't burn away, ensuring a consistent flame height and maximum heat output during extended use.
• Superior Capillary Wicking: Features a high-absorbency cotton bottom that efficiently draws kerosene from the tank to the burner, preventing "dry spots" and ensuring a steady, reliable fuel supply.
• Precision-Stamped Metal Pins: Equipped with factory-aligned mounting pins that snap directly into the wick adjuster mechanism, allowing for a perfect "level" installation that prevents uneven burning or smoking.
• Clean-Burn Technology: Specifically woven to promote a clean, soot-free blue flame, significantly reducing the "kerosene smell" during startup and shutdown when used with high-quality 1-K fuel.
• Reinforced Stitching: The transition between the fiberglass top and cotton base is double-stitched to prevent fraying or separation, even after multiple "dry burns" to remove carbon buildup.

Compatibility & Fitment

This wick is specifically designed for 10,000 to 11,000 BTU portable radiant and convection heaters. Key compatible models include:

• Sengoku: Fits the HMN-110 (Heatmate) and OR-77 models.
• KeroHeat: Compatible with CTN-110 and CV-110 portable units.
• Mega Heat: Direct fit for the MGN-110 series.
• Comfort Glow: Fits various radiant models including the GRW-6 and GRW-10.
• Note: This is a "Pinned" wick. If your heater's wick adjuster does not have slots for metal pins, this model will not fit. Always verify the BTU rating of your heater before purchasing.

When to Replace

• Knob is Hard to Turn: If the wick adjuster knob feels "sticky" or requires force to raise, the wick is likely saturated with tar and carbon deposits that are jamming the mechanism.
• Strong Fuel Odor: A persistent smell of unburned kerosene while the heater is running usually indicates the fiberglass top is fouled and cannot maintain a clean combustion temperature.
• Flame Won't Reach Full Height: Even with a full tank, the flame remains low or uneven, suggesting the cotton bottom is clogged with water or impurities from old fuel.
• Visible "Carbon Crusting": The top of the wick looks like black, hard charcoal. While a "dry burn" can fix this temporarily, once the fiberglass becomes brittle, it’s time for a new one.
• End-of-Season Maintenance: For the best performance and safety, it is highly recommended to start every winter season with a fresh, clean wick.

Installation Tips

• Safety First: CRITICAL: Ensure the heater is completely cool and the fuel tank is empty before disassembly. Work in a well-ventilated area to avoid inhaling fumes.
• The 60-Minute Soak: PRO TIP: After installing the new wick and filling the tank, you MUST wait at least 60 minutes before lighting it. Lighting a "dry" wick will permanently ruin the fiberglass top in seconds.
• Pin Alignment: When installing, ensure all three pins are fully seated in the adjuster sleeve. If one pin is loose, the wick will sit crooked, causing a lopsided flame and excessive soot.
• Fresh Fuel Only: Only use clear 1-K grade kerosene. If your fuel has a yellow tint or contains water, your new wick will "tar up" and fail within days.
• Dry Burn Weekly: To extend the life of your new AW4E wick, perform a "dry burn" once a week by letting the heater run out of fuel naturally. This burns off the tar and keeps the fiberglass soft.
