Interesting question!

I have an adaptor (not a Coleman product) and it has the standard BBQ regulator on it. Works fine, though the stove runs a fair bit hotter on max. than it will from a 1-lb. bottle -- enough to turn the burner supports glowing red. The solution of course is to throttle back using the stove's control valves.

Looking at the Coleman website, it seems they sell a 5-foot bulk adaptor with attached hose or a separate bulk adaptor plus assorted splitters and hoses. There's no evidence of a standard-type regulator. I suspect there's an orifice built right into the bulk adaptor, designed to control flow and pressure to appropriate levels. So, if you're using all-Coleman components, you should be good to go. (Being wise, of course, you will test this before relying on it.)

Let us know how it works out. I may want to upgrade.
