Royce,
That's probably because it can't be done, at least if using a single
typical hand-held propane or MAPP DIY-type torch on a typical 2" diamater
boiler shell (min Type L) with 1/16" heads. But it's not the gas it's the
delivery systen that makes the difference. A regulated air/propane or
air/MAPP turbo-type plumber's torch (which you apparently have) will easily
do the the job. Given the right delivery system and volume, an
air/cow-farts torch would melt copper.
