Learn how to assemble, wick, and light your UCO candle lantern safely. This step-by-step guide covers common mistakes and tips for first-time users.

Quick answer

Assemble the lantern by threading the wick through the burner cup, filling the fuel reservoir, and lighting the wick. Always use a fresh wick and trim it to 1/8 inch before each use.

Before you start: what you need

A UCO candle lantern, a fresh wick (or the one that came with it), a lighter or matches, and a safe, flat, non-flammable surface. Avoid using old or frayed wicks, as they can cause uneven burns or flare-ups.

Common mistakes to avoid

Don't over-tighten the glass globe; it can crack. Don't fill the fuel reservoir past the fill line. Don't light the lantern indoors or near flammable materials. And never leave a lit lantern unattended.

Step-by-step setup

1. Prepare the wick: Remove the old wick if present. Insert a new wick through the burner cup so that about 1/8 inch protrudes above the cup. Trim any excess with scissors. A wick that is too long will produce a smoky, sooty flame.
2. Fill the fuel reservoir: Unscrew the burner assembly. Fill the reservoir with lamp oil or kerosene to the fill line. Do not overfill. Screw the burner assembly back on tightly. Overfilling can cause fuel to leak when the lantern warms up.
3. Attach the glass globe and top cap: Place the glass globe over the burner cup. Screw the top cap onto the burner assembly. Ensure the globe sits evenly and the cap is snug but not overly tight. A cracked globe is a fire hazard; replace it immediately.
4. Light the lantern: Use a long-reach lighter or a match to light the wick through the opening in the top cap. Adjust the flame height by turning the top cap slightly. A steady, low flame is safest and most efficient. Never light the lantern indoors or near tents, dry grass, or overhanging branches.
5. Monitor and extinguish: Keep the lantern on a stable, heat-safe surface. To extinguish, blow gently on the flame or use the snuffer cap if available. Allow the lantern to cool completely before handling or storing. Always let the lantern cool for at least 10 minutes before touching the globe or refilling.
