I learned that cheap butane canisters have a fixed orientation for vapor feed.
That’s the tricky part of testing non-standard canisters. You never know when there’s a hidden dip or vapor feed tube. You could wind up feeding liquid fuel into the burner when you least expect it.
Worse, you could use it five times without incident, and then the fifth time, something shifts, and WHOOMPH! you get a fireball. Do your homework first with non-standard canisters.
The cheap butane canisters should, with this post, now be a fairly known quantity.
I assume those table-side stoves in restaurants have the index tab pointing up.
Yes. There’s a fixed fitting that the canister attaches to. On the fitting, there’s a metal tab that fits into the gap on the canister’s collar. There’s only one easy way to fit a canister in. You’d have to really work at it to screw it up.
This re-enforced that I should keep a vapor-feed canister in ITS upright position.
Yes, unless you’re using a warmed up stove AND have a preheat mechanism on that stove.
And it begs the question – now that I know how to use it more safely – where can I find these $1.25 canisters?
Just FYI: I’ve got two more posts on cheap butane: 1) A general look at butane adapters and 2) refilling canisters with cheap butane. I should have them both done by the end of the month.
As for where to find the canisters, I would look at restaurant supply stores. I also have seen them in supermarkets. The best prices here are in the asian markets, although there is one Dollar Store that sometimes has them.
The fuel is really only good so long as the fuel temperature is above 40F/5C. I usually plan on using 100% butane only if the temps are above about 50F/10C since fuel temperature falls with use.
