spent the weekend in sub zero temps (snow and freezing rain over night) and used a ProCat to keep the Surf Side toasty. Has anyone out there connect a ProCat to a 20lb tank? Alternately, has anyone used their 20lb tank to refill the smaller green disposable bottles?
It would be best to contact Coleman directly to see if it is safe to connect your ProCat to your 20lb tank. The smaller green cylinder tanks used with portable propane
devices are pressurized differently and, although someone here might actually hook their ProCat up to their 20 lb tank, it does not necessarily make doing so a safe venture. Coleman knows what's safest.
There are adapters that are used to refill small propane
cylinders but there appears to be some controversy regarding the legality of doing so in various states. You might use the search engine to locate previous threads on this topic.
