Hi Joshua, Brett,
Below are some pictures of one of my prototype stoves operating with a pre-heat tube and without a pre-heat tube, The canister has been in the freezer at -20C (-4F).
“My comment was mainly to stop the FUD-spreading of remote canister mount being 'designed' to allow for inverted duty. This one ISN'T, doing so would result in operating it outside of the manufactures intended purpose and should ONLY be done with that understanding and that you MAY be doing something potentially dangerous.
Potentially, from my understanding everyone seems to believe this is a dangerous thing. I suspect, however, that this is only dangerous if you're trying to run the thing at full-tilt. Liquid HAS to vaporize before it can ignite. If you're spraying a crap load of liquid into cold air you may be spraying it faster than it can light in the flame path... but it may light a moment later (aka after it's spread all over).
I suspect that, as long one is careful and doesn't open the valve up too far, you'll be fine. (Realize, I have yet to have a good opportunity to do this myself).”
The fact that it CAN be inverted without a pre-heat tube is a concern to me, (manufactures design or warning or not), in my stove designing and testing I have experienced how easily it is to have a flare-up with an inverted canister stove and I certainly would not like to have a big flair-up inside a tent.
From what I can find out the density of gas in liquid form is approximately 200 times more than it is in gaseous form. (Please correct me if that is incorrect.) so it does not take a lot of liquid gas to make a large air gas mixture.
