d) For the piping choose a place which is the least exposed to
cooling influences as possible. If possible, the chimney should be
inside the house.
e) The inner walls should be perfectly flat and free from any
obstacles. Avoid any bends where the pipe joins the brick chim-
ney.
f)
It is very important
that the joins of the pipes are well sea-

The following procedure is to test that the chimney is water
tight:
Cover the exit in the roof.
Put paper and wet straw in the lower part of the chimney and
light them.
See if any smoke comes out of any possible cracks and seal
them.
