LOW EMISSION fire lighting

Smokeless combustion is a way of lighting a fire able to significantly reduce the emission of harmful substances. The wood burns
gradually from the top downwards, so combustion is slower and more controlled. Burnt gases pass through the high temperatures of
the flame and therefore burn almost completely.
Place the logs in the hearth a certain distance apart as shown in the
the top, or vertically in the case of tall narrow combustion chambers. Place the fire starter module on top of the pile, arranging the first
logs in the module at right angles to the pile of wood.
Fire STARTER MODULE. This fire starter module replaces a paper or cardboard starter.
Prepare four logs, 20 cm long with a cross section of 3 cm by 3 cm. Cross the four logs and place them on top of the pile of wood
at right angles, with the fire lighter (wax impregnated wood fibre for example) in the middle. The fire can be lit with a match. If you
want, you can use thinner pieces of wood. In this case, you will need a larger quantity.
Keep the flue gas exhaust valve and combustion air regulator open.
After lighting the fire, leave the combustion air regulator open in the position shown:

Wood
IMPORTANT:
• do not add further wood between one complete load and the next;
• do not suffocate the fire by closing the air intakes;
• regular cleaning by a chimney sweep reduces fine particle emissions.

NORMAL OPERATION

IMPORTANT: For safety reasons the door of the hearth can be opened only for the loading of the fuel. The hearth
door must always remain closed during operation or rest.
After having positioned the registers correctly, insert the indicated hourly wood load avoiding overloads that cause anomalous stresses
and deformations. You should always use the product with the door closed in order to avoid damages due to overheating
(forge effect). The inobservance of this rule makes the warranty expire.
For safety reasons the door of the appliances with constructive system 1, must be opened only for the loading of the fuel or for
removing the ashes, while during the operation and the rest, the door of the hearth must remain closed.
The appliances with constructive system 2 must be connected to their own flue. The operating with open door is allowed under
supervision.
With the controls positioned on the front of the appliance it is possible to adjust the heat emission of the hearth. They have to be
opened according to the calorific need. The best combustion (with minimum emissions) is reached when, by loading the wood, most
part of the air for combustion flows through the secondary air register.
Never overload the appliance (see the hourly wood load in the table here below). Too much fuel and too much air for the combustion
may cause overheating and then damage the stove. You should always use the appliance with the door closed in order to avoid
damages due to overheating (forge effect). The inobservance of this rule makes the warranty expire.
The adjustment of the registers necessary to reach the rated calorific yield with a depression at the stack of 17-20 Pa 1,7-2 mm of
column of water) is the following one: see chapter TECHNICAL DESCRIPTION. The appliance works as an intermittent operating
appliance.
In the event that the water temperature exceeds the tripping temperature of the safety devices, immediately
suspend the feeding of wood, and make sure that the water temperature and the flame decrease, eliminating the
causes of the overheating (if necessary by closing the air register).
If the water system is connected in the appliance, the hot water tap can be opened to speed up the cooling of the
appliance.
Besides the adjustment of the air for the combustion, the intensity of the combustion and consequently the thermal performance of
the device is influenced by the stack. A good draught of the stack requires a stricter adjustment of air for combustion, while a poor
draught requires a more precise adjustment of air for combustion.
To verify the good combustion, check whether the smoke coming out from the stack is transparent.
If it is white, it means that the device is not properly adjusted or the wood is too wet; if instead the smoke is gray or black, it signals
that the combustion is not complete (it is necessary a greater quantity of secondary air).
WARNING: When fuel is added onto the embers in the absence of a flame, a considerable amount of fumes may develop.
Should this happen, an explosive mixture of gas and air may form, and in extreme cases an explosion may occur. For safety
reasons it is advisable to perform a new lighting procedure with the use of small strips.
