Safety Measures; Intervention In Case Of Emergency; Chimney - Bronpi SIERRA Instructions D'installation, D'utilisation Et D'entretien

Keep any flammable or heat sensitive materials (furniture, curtains, and clothing) at a minimum distance of about 100cm, including the area in
front of the loading door. Measurements below the minimum distances should not be used.
4.1.

SAFETY MEASURES

During the installation of the equipment, there are risks to be taken into account, so you should follow the next safety measures:
a. Do not place flammable objects above.
b. Do not place the oven near combustible walls.
c. The oven should only be used when the ash pan is inserted.
d. It is recommended to install carbon monoxide detector (CO) in the room where the equipment is installed.
e. Use the gloves included for opening and closing the door as well as manipulating the controls as these can be very hot.
f. Solid combustion residues (ashes) should be collected in an airtight container and resistant to fire.
g. The appliance should never be turned on in the presence of emission of gases or vapours (e.g., linoleum glue, gasoline, etc).
h. Do not place nearby flammable materials.
WARNING!!
It is noted that both the oven and the glass get very hot and should not be touched.
4.2.

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 OUT THE FIRE 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 oven and primarily has two functions:
- Evacuate the smoke and the gas safely out of the house.
- Provide sufficient draught to the oven 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 conditions.
(Many of the claims due to malfunctioning reasons refer exclusively to a bad draught).
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 oven:
• 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 draught for
the ovens varies 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 oven, 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 D18 shows some examples of solution.
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. Not recommended
