INSERTO 70 L
The wood is not a fuel which allows a continuous operation of the appliance, as consequence the heating all over the
night is not possible.
WARNING: The continuous and protracted use of aromatic wood (eucalyptus, myrtle etc.) quickly damages
the cast iron parts (cleavage) of the product.

11. LIGHTING

Place the lever of the primary and secondary register totally to the right (all open). (see Picture 1).
To light the fire, it is suggested to use small wood pieces together with paper or other traded lighting means.
It is FORBIDDEN to use any liquid substance as for ex. alcohol, gasoline, oil and similar.
When wood starts to burn, it is possible to feed it again by opening slowly the door, in order to avoid leaks of smoke,
and adjust the air for the combustion according to the provisions of CHAP. 12.
Never overload the appliance (see the technical table - max. quantity of fuel that can be loaded / hourly
consumption – (see CHAP. 18).
Too much fuel and too much air for combustion can cause overheating and therefore damage the same.
Never switch on the device when there are combustible gases in the room.
To perform a correct first lighting of the products treated with paints for high temperature, it is necessary to know the
following information:
the construction materials of the involved products are not homogeneous, in fact there are simultaneously
parts in cast iron, steel, refractory material and majolica;
the temperature to which the body of the product is subject is not homogeneous: from area to area, variable
temperatures within the range of 300° C - 500° C are detected;
during its life, the product is subject to alternated lighting and extinguishing cycles in the same day, as well as
to cycles of intense use or of absolute standstill when season changes;
the new appliance, before being considered seasoned has to be subject to many start cycles to allow all
materials and paints to complete the various elastic stresses;
in detail, initially it is possible to remark the emission of smells typical of metals subject to great thermal
stress, as well as of wet paint. This paint, although during the manufacture it is backed at 250 ° C fo r some
hours, must exceed many times and for a given period of time the temperature of 350 ° C before becoming
completely embedded in the metallic surfaces.
Therefore, it is extremely relevant to take these easy steps during the lighting:
1) Make sure that a strong air change is assured in the room where the appliance is installed.
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 enameled
surfaces. Enameled 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.

NORMAL OPERATION

Insert the indicated hourly wood load (see CHAP. 18) avoiding overloads that cause anomalous stresses and
deformations. You should always use the INSERTO 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 appliance, 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.
The adjustment of the registers necessary to reach the rated calorific yield with a depression at the stack of 12Pa
(1,2mm of column of water) is the following one:
Insert – 70 L
Besides the adjustment of air for combustion, the intensity of the combustion and consequently the thermal
performance of your appliance 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.
