Thoughts on using a gasmate heater in tent awning

Hi All ,

Has anyone used one of those gasmate heaters (the one's that screw on top of the bottle) in a tent awning?.

what I am thinking of doing is putting our 2 RV5's up with awnings facing each other with the peaked side panels on one side only thus creating like a 3 sided room between the 2 tents and would like to use one of the above mentioned heaters to warm the area while keeping in mind the saftey issues of cause.

Has anyone tried this sort of setup with tents and how much heat will the unit put out, also any other issues that I should consider would be appreciated

Thanks
regards
