My boyfriend bought a grill for my roommates and me, a gas grill. It's a Kenmore I think? Anyway, it's a 2 burner grill near the side burner. The assembly instructions were desperate, and the hose the tank attached to, one picture showed it going over a lump towards the side with the side burner (which is how we did it), but another picture showed the hose purely underneath the main part of a set of the grill. Is this a big issue that we should fix? We already used the grill once with no problems.

Also, nearby appears to be nowhere to put the tank...the picture shows it on the bookshelf by the legs, but the tank won't fit, and it is a 17 lb cistern (the book says no more than 20 lb.)

Thanks.
Why not to put mirrors above mantelpieces?
Answers:    The hose routeing is probably preventing you from puting the cistern under the grill.If it ain't broke don't fix it :^)
