Help...Coleman 228 Blowing Holes in Mantles

[BobR]

Hi everyone, My Coleman 228 lantern keeps blowing holes in the mantles after just a few minutes of operation. I am using #21 tie on or insta-clip genuine Coleman mantles. The lantern makes a popping noise after lighting for a about a minute or so after lighting. Any ideas as to what the problem might be? Thanks

Steve E had a similar problem this last weekend with his propane lantern. We were thinking it was a pressure issue. How much are you pumping it up? Steves, blew a hole in the bottom and what was left was a jet of gas that was blowing pretty hard. First one goes, then the next within a minute of each other. Doug

I would check the needle valves and regulators for any loose dirt, it sounds like a a piece of dirt is restricting the fuel flow and when enough pressure is built up it pushes the piece through.

Just my thoughts

From Coleman site:

Question
Why does my lantern “pop” and blow out the mantles during use or right afterwards?

Answer
There are two causes for “popping” at the mantles during the use of a Coleman® Lantern or when the lantern is shut off.

The first is the presence of water droplets in the tank of a liquid fuel lantern. Condensation can occur in the fuel can or in the tank of a lantern stored for long periods. If water droplets are in the lantern’s tank, they can be drawn up into the fuel and air tube and when they hit the hot generator and pass into the burner assembly, instantly turn to steam. This produces an increase of pressure in the burner assembly and will cause a “pop” at the ends of the burner tubes, which can break a mantle. This will occur while the lantern is running. To cure this, empty the fuel from the tank and rinse it out with clean fuel to remove all traces of water. Refill the tank with fresh fuel.

The second can occur on both liquid fuel and propane lanterns. In the end of each burner tube, where the mantles are tied on, is a screen assembly. This screen prevents the flame inside the mantle from pre-igniting the fuel inside the burner assembly. If the screen at the burner tube falls out or develops a large hole, when the lantern is turned off and the pressure inside the burner decreases, the flame in the mantle will light the fuel inside the burner causing the “pop” and usually breaks the mantle. The cure for this is to either replace the burner cap with the bad or missing screen or the entire burner assembly. Some burner assemblies do not have replaceable burner caps.

Thanks everyone...I'll be looking into this.

Doug, I pump about 15 strokes before lighting

Starleen I have been using fresh fuel. I think I need to check those screens
