I bought a Broil Mate 4554 BBQ several years ago and it was using natural gas… now I’m moving to an apartment that doesn’t have an outdoor natural gas pipe… so the hose that usually goes into the natural gas needs to go into a propane tank, but I don’t know where to find one… any ideas?

It’s a fair question, and one we’ve seen here on the BBQ Smoker Site before.  If natural gas grilling is your thing, and you’ve been used to a natural gas pipe feeding your unit, moving to a setting where such a pipe feed is absent can indeed cause you some difficulty!
