b) The characteristics of the bricks in accumulating heat allows
for the house to remain warm for longer after the fire has been
put out.
c) It may be built to individual tastes.
d) If it is well built, it may be more fire-resistant than metal
chimneys.
Brickwork chimneys must be well lined to avoid smoke cooling.
They must be built using materials that withstand high temperatures and
corrosion.
They may be round, square, etc. what matters is their size.
Brickwork chimneys for the Hergóm oven must respect the measurements
indicated in the chapter titled TECHNICAL DATA.
The advantages of metal chimneys are:
a) Easy installation.
b) Slight changes in chimney direction can be made, leading to
greater flexibility in the choice of location for the range cooker.
c) Due to there being curved elbow joint, sharp edges that
make draught difficult are removed.
4.- Connecting the chimney
The vertical run of the chimney must avoid elbow joints and long horizontal
sections, as they make the draught difficult and favour the formation of
creosote and soot.
It is extremely important to seal the attachment ring – elbow joint – tube
connections using refractory filler, plaster or any other suitable material to
prevent air from entering the area.
The joints of the tubes forming the chimney, in the event of using metal
tubes, must be sealed during fitting, with the narrower ends pointing
downwards. This prevents the creosote that is formed inside them
reaching the outside.
This advice must be following whenever wood or coal fuel is used.
5.- Draw valve assembly
The draw valve control element can be found inside the instructions
manual packet.
The following figures display the different positions that can be used
based on the situation of the side wall where the oven has been installed.
This will enable users to place the draw valve control in the most
functional and suitable position on the said side wall.
