I thought all propane lanterns were idiot proof.  Apparently not.  🙂

I can't get this thing to light.  I reamed the air tube which is also the gas delivery tube and encountered no obstructions or debris.  I open the valve and gas is flowing at the valve where the air adjustment is for high altitudes(arrow below), but apparently nothing at the mantle.  Is there something obviously missing that you Bernzo owners recognize?

Thanks for any help.

Gas easily flows out of here.

This is what the valve adjustment looks like when high altitude is set, exposing the air holes.Valve open - hi altitude.jpg

It's gotta be in the Bunsen tube. Ream it out  and ream it good!

Is it possible the jet (orifice) is enlarged/missing? Far too much fuel will blow the flame out before it even lights.

Seriously gotta be like Timm says. I think I remember blowing mine all out with compressed air to make sure I had a good flow. That's about it.

Not sure I'd go that far yet.  🙂  I'm now suspecting this lantern was only used once.  As it turn out, the globe on this is an original Bernz-O-Matic, but the lettering is very faint.  I accidentally noticed the lettering at a certain angle while cleaning it.  I suspect the mantle may be original too.  The lantern came with the empty Bernzo mantle package and the burned in mantle faintly has Bernz-O-Matic on it.


I've pulled the burner cap off for the second time without breaking the mantle.  I can't believe that!   I just used a computer compressed air duster and the tube is clear.  I had reamed it out before, but nothing came out.

I've pulled the orifice out and couldn't see light through it, but suspect it had to be flowing.  I put it in the ultrasonic cleaner and shot some carb cleaner through it, but most of it went back on me.  🙁   I can now see light through it.  Dang, what a tiny orifice!  I'll try firing it up again.

I tried again and still no go.  I could be wrong, but I don't think this is where it should light.  This happened when holding a lighter to the mantle and quite a bit of gas had been dispensed.  There was quite an initial fireball when all that propane ignited.  🙂  There's got to be something simple I'm missing.  I'm assuming that this is essentially the mixing chamber to mix air with the gas being delivered to the mantle.  There are no other tubes at the mantle.

Once I removed the ceramic burner with the mantle, the entire tube was available and reamed out.   I'll look again tomorrow.  I didn't think to look at all the holes in the burner itself when I had it off.

Hi Jim,
try removing the mixing valve from the fuel pipe and check the threads for cracks or other damage. Many times these are chewed up while cleaning or changing the tip. If the tip isn't held firmly it will leak badly.

Not only should it, but it MUST seat in the end of the fuel pipe. Either the pipe end or the gastip is distorted. There also could be something in the fuel pipe preventing the tip from sliding all the way in. I think you're on to the problem now.

There was a slight burr preventing the tip from going into the tube.  A few wipes with 600 grit sandpaper made short work of that.  I notice a big difference now.  🙂  Instead of gas gushing out, it's coming out as a fine stream.  The lantern lit right up.

Thanks for the help!

Dana,

Thanks for that confirmation earlier about inserting the tip.  It slid in all the way, up to the end where it’s thicker.  Perhaps my previous pic was too small to easily show this.

This is the TX-900, but the bag it came in with the paperwork had one cardboard side of a box stating TX-700. I’m going with TX-900 because that’s what’ on the lantern label.  🙂

It doesn’t appear that bright, but I need to try it at night to really judge.  I originally only got this for the globe but once in hand, had to fire it up.  🙂. I’ve since put the original globe safely away.  It’s now sporting a blemish 200A globe.

These can be a little shy on lumens for the reason you found. They have a very small orifice. Later tonite you will be able to better judge the light output and make your final fuel/air adjustment for your altitude. See, it aint rocket science at all.

Alex,

I can't say that it's grown on me.  It's propane and propane doesn't do a lot for me.  If the way cool vent fit on a 200, it would probably be cannibalized already.

I just got home and lit it and it isn't very bright for propane.  When I wrapped a finger around the fresh air inlet, it burned much whiter, so if this is going to be a user, I'll need to plug some of the air holes as it's obviously burning too rich.

Looks great, Jim!

I've been hoping to run across one of these, but so far no luck. I have most of the Rocket Launcher stove, but have never gotten around to working on it.

If blocking off the air vents a bit helps, are you running it in the high-elevation setting? Try screwing that collar all the way down over the holes. You look like you're burning lean--rich means soot and yellow flames.

Timm,

I'm around 100' elevation and can't set the lantern for any lower elevation.  That collar isn't quite the restrictor it appears.  There's no soot or flames, but the best way I can describe it is that the mantle looks like an yttrium mantle running as is, and looks more like a thorium mantle when I partially cover that collar for the fresh air inlet.

I may play a bit with it tonight.   This thing is starting to wear me down.  I didn't want it except for the globe, but it's in such mint condition, it's beginning to grow on me.  I picked up more food for it at an estate sale yesterday, another old (er) bottle of propane.  🙂

I pulled the tip and wrapped some teflon tape around the end and re-inserted it, just to ensure a good seal at that spot.  I then wrapped the air inlet with some painters tape to partially block the holes.  It's now burning whiter but probably not much brighter, if at all.  However, moving the altitude adjustment now seems to make a slight difference.  I'm thinking that tip orifice is a bit too small for this lantern.  Opening the valve little to a lot seems to make no difference.  Someone must have tampered with it for the tip to not have been in the tube to begin with.

>>Hmmm...a propane lantern is both starting to wear you down and beginning to grow on you..... 🤔

I have a few propane lanterns, but just don't use them since collecting liquid fueled GPA's.  I still have a NIB Northstar that I've done nothing with and am not even certain why I bought it.  However, this one is pretty unique and I really like the vent which reminds me of a flying saucer from the 50's documentary 'Earth Versus the Flying Saucers'.   🙂

I have a Northstar as well and a few others, Jim.  Keep them around just in case.  Especially the single mantle ones!  I even have a decent red and yellow American Camper.  😀

As I understand it, the newer bottles have a larger diameter at the seam so won't fit in the tube.  Someone here has a procedure for grinding or filing down that seam.  No thanks, I'll find old bottles at yard sales.  Even then, the old bottles are extremely tight in mine, to the point that even the paper label is in the way.  Somewhere I saw where someone opened the seam at the bottom of the tube so they could use the current bottles.

K let's get back to cylinders. Older cylinders were manufactured by reducing the diameter of on half and inserting it into the other thereby maintaining an equal outside diameter. Newer ones are made by expanding one of the halves and placing it over the other. There are several variations on this theme but the end result is a cylinder that has a larger diameter at the seam preventing it from sliding into the tube of the lantern or stove. Some folks grind, file, or otherwise machine the seam to make it fit but I don't recommend doing anything to the structure of a pressure vessel. 
     The cylinders were even skinnier early in the propane era. Here's a pic of an early TX-700. There's room for the instruction and a spare pack of mantles in the tube with room to spare.

Thanks for that info.  I thought the older cylinders I was acquiring were awfully tight in the tube, but it makes sense if they were getting a larger diameter over the years.  Rubbermaid bought BernzoMatic in 1982 and Worthington bought them in 2011.  No reason for either of them to even think about the older propane lanterns and stoves, not that it would have mattered.
