d) Install the conduit in an area as protected from the cold as possible. If possible, the
chimney should be built inside the house.
The internal walls must be perfectly smooth and free from obstacles. Avoid bottlenecks
where pipes join to the brick chimneys.
f) It is very important to ensure that the joints of the pipes are well sealed to avoid
possible cracks through which air may enter.
In order to verify the air-tightness of the chimney, you may:
- Cover the outlet on the roof.
- Introduce damp paper and straw at the bottom of the chimney and light it up.
- Watch for possible cracks through which smoke leaks out and seal them.
