otherwise provide. All joints and
seals through which air may enter
and that would affect the draw have
been sealed with refractory material.
III.- BUILDING THE CHIMNEY
The way the cooker is installed will decisively affect safety issues and
how it works.
It is important to install the fireplace correctly.
In order to ensure it has been installed correctly, it should be installed by a
professional.
A.- Chimneys.
The way the cooker works depends on:
d)
The chimney.
e)
How it is used.
f)
The quality of the fuel used.
Over the years you may change the type of fuel you use but, once the chimney
has been installed in a given place, it is not so easy to alter or reposition.
Therefore, the following information will help you decide whether you can use
your present chimney or not or help you decide to build a new one.
This information will help you make the correct decision.
1.- How chimneys work
A basic knowledge of the dynamics of chimneys will help you make the most of
your cooker.
Chimneys:
b)
Safely evacuate smoke and gasses from the house.
b) Provide sufficient draw in the hearth to keep the fire alive.
What is the "chimney draw"?
The tendency air has to rise generates the chimney effect.
When a cooker is lit, hot air rises through the chimney. The chimney flue heats
up and keeps it drawing. Until the cooker and the chimney are hot enough, the
chimney effect will not work properly.
The chimney effect depends on the location, size and height of the chimney.
The following must be taken into consideration:
- Chimneys located inside a house keep warm and, therefore, chimney draw
is greater.
- The chimney size recommended by the manufacturer will provide a good
chimney effect.
