Low Emission Fire Lighting; Normal Operation; Operation During Transition Periods - LA NORDICA Inserto 70 Crystal Angolo Manuel Utilisateur

2. During the first starts, do not load excessively the combustion chamber (about half the quantity indicated in the instructions manual)
and keep the product continuously ON for at least 6-10 hours with the registers less open than the value indicated in the instructions
manual.
3. Repeat this operation for at least 4-5 or more times, according to your possibilities.
4. Then load more and more fuel (following in any case the provisions contained in the installation booklet concerning maximum load)
and, if possible, keep the lighting periods long avoiding, at least in this initial phase, short ON/OFF cycles.
5. During the first starts, no object should be leaned on the appliance and in detail on enamelled surfaces. Enamelled surfaces must not
be touched during heating.
6. Once the «break-in» has been completed, it is possible to use the product as the motor of a car, avoiding abrupt heating with excessive
loads.
After testing the proper working of the appliance, some days from the installation, it is possible to proceed with the
construction of its aesthetic covering.
WARNINg: During the surround building operations it must kept in mind possible and subsequent electrical installed parts
maintenance (Fans, temperature probe, etc) and with hydraulic systems all parts connected to the thermo-fireplace.

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
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
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 (1A - 2A). After lighting the fire, leave the combustion air regulator open
in the position shown in the Picture.
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

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.
With the registers located on the front of the device, it is possible to adjust the heat emission of the same. 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. Too much fuel and too much air for the combustion may cause overheating and then damage
the product.
You should always use the appliance with the door closed in order to avoid damages due to overheating (forge effect).
The adjustment of the registers necessary to reach the rated calorific yield with a depression at the stack of Pascal (see chap. TECHNICAL DATA
SHEET) is the following one: see chap. TECHNICAL DESCRIPTION. The appliance works as an intermittent operating 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.
