- Cracks in the chimney, a poorly sealed or dirty door, if air is getting in through the
joins in the pipes, or through another piece of equipment connected to the chimney etc.
could mean that the draft is insufficient.
2. – Formation of soot and its cleaning.
When wood is burned slowly tar and other organic vapours are produced, which
when combined with the damp in the environment form tar. Tar vapours can condense if
the walls of the chimney are cold. If tar is set alight this could produce high temperature
fires. Any accumulation of tar must be eliminated.
Due to the fact that the accumulation of tar depends on so may variables it is very
difficult to foresee when the chimney has to be cleaned.
A visual inspection is the surest way to see if your stove is free from tar.
For this reason we recommend that the equipment is installed so that it can be
easily accessed.

3. - Options

If a chimney is going to be built for the Mallorca fireplace you have two alternatives:
a) Brick chimneys.
b) Metal chimneys
Studies show that there is not a great deal of difference between the efficiency of
the draft between brick and metal chimneys. The choice is up to you.
Whenever possible build you chimney inside the house where the draft will be
better, there will be less tar and it will last longer.
The advantages of brick chimneys are:
a) The mass of bricks and small slabs reduce the cooling of smoke in the
chimney.
b)The ability of the bricks to accumulate heat allows the house to stay hot
longer after the fire has gone out.
c) It can be built to your own specifications.
d) If it is constructed correctly it could be more resistant to heat than a metal
chimney.
Brick chimneys must be lined correctly to prevent smoke from cooling.
They must be constructed with materials which support high temperatures and
corrosion.
They can be round, square etc. as what matters is the size of the chimneys.
For brick chimneys the Mallorca fireplace must comply with the measurements
listed in the section on TECHNICAL SPECIFICATIONS.
The advantages of metal chimneys are:
a) They are easy to install.
b) They allow slight changes in the direction of the chimney, which gives
greater flexibility in the choice of the place where the stove is installed.
c) Due to the fact that there are curved bends actual angles which impede
draft are eliminated.
