INTERVENTION IN CASE OF EMERGENCY

If there is fire in the chimney:
a. Close the loading door.
b. Close primary and secondary air intakes.
c. Put the fire out by using carbon dioxide extinguishers (CO2 powder).
d. Request for the immediate intervention of the fire-fighters.
DO NOT PUT THE FIRE OFF WITH WATER.
WARNING:
The manufacturer declines any responsibility for the malfunction of an installation not subject to the requirements of these
instructions or the use of additional products not appropriate.

CHIMNEY

The chimney is of basic importance in the proper functioning of the insert and primarily has two functions:
- Evacuate the smoke and the gas safely out of the house.
- Provide sufficient draft to the insert in order to keep the fire.
Therefore, it is essential that it is made perfectly and that it is subjected to maintenance operations in order to keep it in good condition
(many of the claims due to malfunctioning reasons refer exclusively to a bad draft). The chimney can be made of masonry or metallic pipe
compound.
It is necessary to comply with the following requirements for the proper operation of the stove:
• The interior section must be perfectly circular.
• It must be thermally insulated along its entire length in order to prevent condensation (the smoke is liquefied by heat shock) and even
more if the installation is outside the house.
• If we use metallic pipe for the installation outside the house, it is compulsory to use thermal insulated pipe. It consist of two concentric
pipes and, between them, there is a thermal insulator. Moreover, we will avoid condensation problems.
• It should not have bottlenecks (enlargements or reductions) and it must be vertical with deviations not higher that 45º.
• Do not use horizontal sections.
• If it has been used previously, it must be clean.
• Respect the technical data of the instructions manual.
** For the fitter
The optimum draft for the inserts vary between 12+/-2 Pa (1.0–1.4 mm water column). We recommend checking the technical information of
the product.
A lower value causes a bad combustion causing carbonic deposits and excessive smoke generation, having leaks and, even worse, an
increase of the temperature that could damage the structural components of the insert, while a higher value leads to a too rapid combustion
with the heat dispersion through the flue.
Materials that are prohibited for the chimney and, therefore, damage the proper functioning of the equipment are: fibre cement, galvanized
steel (at least in the first few meters) and rough and porous interior surfaces. Drawing D42 shows some examples of solution.
All inserts that send smoke to the exterior should have their own chimney.

INSTALLATION, OPERATING AND SERVICING INSTRUCTIONS
(1) Stainless steel AISI 316 chimney with double insulated
chamber and material resistant up to 400°C. Efficiency
100% optimum.
(2) Traditional clay chimney with square section and
holes. Efficiency 80% optimum.
(3) Chimney with refractory material and double insulated
chamber and exterior coating made of lightweight
concrete. Efficiency 100% optimum.
(4) Avoid chimneys with rectangular interior section
different to the one of the drawing. Efficiency 40% poor.
