Combustion Control And Operation - Caminetti Montegrappa TECH 3 Directions For Installation, Use And Maintenance

3.3 Combustion control and operation
Once the fire is lit, you should keep it efficient. For those who are not experienced and will use this appliance for the first time a
period of adjustment will be needed. Here below find some tips for efficient lighting and burning:
Only burn dry wood: wet or damp wood is hard to ignite, slow to burn, reduces the temperature inside the firebox and
produces more smoke and less heat.
A bed of live coals at the bottom of the fire keeps the firebox temperature high enough to ensure easy lighting of the new fuel
and correct combustion; fill the firebox with additional fuel as soon as the firewood pieces turn into coals.
Load the firebox with 3 or 4 wood pieces each time. In order to burn correctly wood needs a critical mass: flames develop only
where the wood pieces touch one another, which means that a single piece of wood hardly burns. Never place the firewood
pieces too close to one another in order to avoid starving the fire of oxygen.
To avoid any damages or cracks to the CMtech® lining never throw the wood pieces into the combustion chamber.
Always open the door slowly, first holding it open only slightly for a few seconds before opening it completely.
Should some smoke blow back, there is no danger, just aerate the room temporarily.
Never overload your appliance by placing more wood than the required optimum quantity (see section 1.3.2). A small fire
receives more oxygen, burns better and produces more heat than a bulk fire, which chokes the the firebox.
Try to reload your appliance before the fire goes out; always keep within reach some kindling or small wood pieces to relight
the fire if necessary.
With the door closed you can achieve perfect control on the wood combustion by adjusting the combustion air control located
at the base of the appliance with the result of saving a good deal of wood in comparison with traditional open fireplaces (Note:
Even though the damper is set on the closed position, it slightly opens to ensure the normal operation of the heater).
After reloading the firebox, in case it is necessary to relight the fire rapidly, it is recommended to fully open the combustion air
control temporarily (see section 3.2, figure 1).
To obtain a performance compliant with the data written on the technical data sheet of section 1.3.2, arrange a
correct quantity of wood in the two limiters on the hearth. To clean the glass efficiently, you can arrange the wood
lengthwise along the whole hearth (generally 3 pieces of 33 cm).
In the fan-assisted fireplace version, the fan switches on automatically when the sensor detects that the temperature of the air
from the outlets is about 40°C, and switches off when the temperature drops below the preset value.
WARNING: Should the convection fan stops for technical problems for a long time, it is recommended that the fire
be kept moderate until the problem is solved.
The use of the appliance as incinerator is FORBIDDEN: household rubbish, coated paper, painted or treated timber
(including pallets), plastic or other synthetic materials must never be thrown into the fire.
Failure to do so causes the release of dangerous and toxic pollutants, which are highly noxious for you, your
neighbours and the environment. Besides, burning household rubbish produces corrosive acids, which may
seriously damage the internal parts of the appliance and the chimney flue, with consequential risk of fire of the
chimney flue itself.
