OUTSIDE AIR INTAKE
For the proper operation of the oven, it is essential that there is air enough for the combustion and re/oxygenation of the environment where it
is installed. In the case of houses built under the requirements of "energy efficiency" with a great degree of air tightness, it is possible that the
air intake is not guaranteed *the fitter must assure compliance with the Technical Building Code. This means that the air must be able to move
for the combustion through some openings connected to the exterior, even when doors and windows are closed. Moreover, it must comply
with the following requirements:
•
It must be placed in so that it cannot be obstructed.
•
It must be connected to the environment where the equipment is installed and it must be protected by a grate.
•
The minimum area of the outlet should not be less than 100 cm2. Check regulations on this issue.
•
When the air flow comes through openings that are connected to the exterior of adjacent environments, it is important to avoid
air intakes in connection with garages, kitchens, toilets, etc.

FUELS ALLOWED/NOT ALLOWED
The fuel allowed is wood. Use only dry firewood (max. moisture content 20%, which corresponds to firewood that was cut two years ago).
The length of the logs will depend on the model (you can check the technical features of each model in our web site www.bronpi.com).
Compressed wood briquettes must be used carefully in order to avoid harmful overheating of the equipment because they have a high
calorific power.
The wood used as fuel must be stored in a dry place. Damp firewood has approximately 60% of water. Therefore, it is not suitable to be
burnt because it makes the ignition more difficult due to the fact that the heat is used to vaporize the water. Moreover, the moisture content
has also the disadvantage that, when the temperature is lower, the water condense in the fireplace and the chimney. This causes the soot
accumulation and condensation, with the consequent risk of fire.
Among others, it is not allowed to use> coal, barks and panels, damp firewood or with paint or plastic materials. In these
cases, the warranty of the fireplace shall terminate. It is forbidden to use waste and it would damage the equipment.
Paper and cardboard should only be used during the ignition.
Below is an instructions table about the type of firewood and the quality for the combustion.

STARTUP (FIRST IGNITIONS)
In order to ignite the fire, we recommend using small wood strips with paper or other means such as fire starters.
It is forbidden to use liquid substances such as alcohol, gasoline, petroleum or similar products.
At the beginning, it is possible that you note smoke or smell which are typically produced when metals are subject to high
temperatures or when the paint is still fresh.
Never ignite the equipment when there are combustible gases in the environment.
In order to do a proper start-up of the products treated with paints used at high temperatures, it is important to consider the following
conditions:
•
The materials of the products are not homogenous due to the fact that there are cast-iron parts and steel parts.
•
The temperature of the product-s body is not uniform: among different zones there are variable temperatures between 300°C and
500°C.
•
During its lifetime, the product is subject to ignitions stoppages even in the same day, as well as intensive use or not use depending
on the season.
INSTALLATION, OPERATING AND SERVICING INSTRUCTIONS
(2) Traditional chimney. The
proper exit section must be,
at least, two times the interior
section of the chimney, the best
is 2,5 times.
(3) Chimney with interior cone
smoke deflector.
