BBQ grills that are listed for use in or on a dwelling will not except
any tank larger than 10 pounds without an adapter. That is done
deliberately to prevent the use of the larger propane cylinders inside a
building. Most regular BBQ grills are not listed as gas cooking
appliances that are suitable to use in doors.

You are talking about the tiny grills that are about worthless. That is
not what the OP is looking for and really has little to do with the
subject of use on a deck. Those things are table top units that use the
disposable tanks. Real grills use the 20 pound tanks.


Now I'm really confused. I just went and looked at my tank. On the top, it
is stamped TW 17.0 , which I would take to mean that the tare weight is 17#.
That feels right, about like a bowling ball. This tank is about knee high,
and in liquid would say it would hold around five gallons just looking at
it. However, full, it weighs a lot. How ARE these things rated? In pounds
of liquid in side? In gallons? When I go get them filled, they charge me
by the gallon. Help me out, please. Is a 17# empty tank called a 20#
because it's approximately twenty pounds empty? Propane weighs 4.24# per
gallon, so that's about 21 pounds for five gallons. Is that a rounded
number, too?
