Carol, here's what I've been able to find out so far this morning. The internet provides much access to different sites and with the firepit issue there seems to be a ton of different options.
The pit we have now (the zero clearance one) is/was made by Heat n Glo. A check of their site does not show our item any more (ours was bought in early 90's) in their list. Its BTU rating (from found paperwork) is 53,000btu. I could not find a rating for the firedancer model but the site did say that shipping to Canada was going to be a cost raising factor due to having to be 'refit' (as they call it) to comply with Canadian standards. The base price also does nto include ANY of the available options, logs, screens etc.
The paperwork on our larger pit also does warn NOT TO BE USED FOR COOKING. The Firedancer site shows many items designed just for THAT purpose. It does also show zero clearance operation, looks like its shown alit on a hardwood floor of some sort.
I cannot find any of our old paperwork on our 'rip roaring' firepit. (I'll think of its name/maker sooner or later) It does look REMARKABLY alike the Canadain 'Yukon' built in the Okanagan. Could be this company bought up the rights to the pit we had and are marketing it under their name?? Ours did have a much higher advertised btu rating (and thus I'd guess the higher flames?) then the Yukon, which was one of the reasons for us buying it.
BTU ratings are like fuel consumption ratings except they come in two different verions, btu's in and btu's out. All companys rate their rating differently. So in that regard, I'd say its buyer beware.
I do know from past experience that the size of the fuel bottle greatly affects performance. I've run our larger pit on a smaller disposable cylinder and only had about half an hour burn time and much lower flame as opposed to the 'advertised' 20/24hr burn time with a 20lb tank. I believe that has to do also with the tanks pressure.
Some Egg buddys we know of, saw our 'high flame' pit, went out and bought a similar one. They found the height of the flame was much less than ours so he proceeded to 'adjust' the regulator valve. This is a safety issue that I'd NOT recommend doing. A thought comes to mind also about 'adjusting' things like regulators. IMHO, if you choose to do this, you are breaking/violating CSA standards and IF that pit causes any damage, the 'insurance' you thought you HAD probably will be null and void, (because you have violated CSA standards) meaning you pay total damages....
BUT, ....thats my opinion!
Sorry for being so long winded....
Bottom line, 'Be Safe' at ALL costs....
