is connected with the hover by flues. These pass through an 

 opening in the wall into a drum from which heat is radiated

Such an arrangement necessitates cutting holes in the wall 

 of the building, and in case of emergency cannot be quickly

 outside the building, which is a decided disadvantage when 

 it is windy or stormy.
