TERMOCAMINO BASE - DSA

4. DESCRIPTION

Definition: thermo-fireplace according to EN 13229.
The appliance is composed of painted and galvanised sheet steel and cast iron.
The fireplace is found inside the boiler, is built in 4 mm thick steel and is reinforced using welded nails. The water in the heating system
circulates in the boiler, which absorbs the heat produced in the fireplace.
The door with viewing window is fitted on extendible ball bearing guides that guarantee the sturdy, quiet, and reliable operation of the
appliance. The counterweight for door raising is supported by two sturdy chains with respective pinions.
The ceramic glass window (resistant up to 700°C) of the door provides a lovely view of the burning flames and prevents sparks and smoke
from getting out.
Room heating takes place:
a) by radiation: the heat is radiated into the environment through the panoramic window and the hot external surfaces of the thermo-
fireplace;
b) by conduction: radiators or heat convectors of the centralised system fed by hot water produced by the boiler.
The device is equipped with registers of primary and secondary air, with which it is possible to adjust the combustion air.
1A- PRIMARY air register
With the air register located under the door of the hearth, it is possible to adjust the air flow through the ash drawer and the grating in
direction of the fuel. The primary air is necessary for the combustion process. In order to open the air flow, the bar must be completely
pulled out.
The ash drawer has to be emptied regularly, so that ash cannot hinder the intake of primary air for the combustion. Primary air is also
necessary to keep fire live.
During the combustion of wood, the primary air register must be opened only a few, since otherwise the wood burns quickly
and the device can overheat.
2A- SECONDARY air register
When the bar is pushed to the back the passage of the secondary is completely open.
The secondary air, passing through the two lateral jambs of the front side, heats itself starting the double combustion and keeping at
the same time the glass clean ( with open register).
The adjustment of the registers necessary to reach the rated calorific yield is the following one:

5. FLUE

Essential requirements for a correct operation of the device:
• the internal section must be preferably circular;
• be thermally insulated and water-proof and produced with materials suitable to resist to heat, combustion products and
possible condensates;
• not be throttled and show a vertical arrangement with deviations not greater than 45°;
• if already used, it must be clean;
• observe the technical data of the instructions manual;
Should the flues have a square or rectangular section, internal edges must be rounded with a radius not lower than 20 mm. For the
rectangular section, the maximum ratio between the sides must be = 1.5.
A too small section causes a decrease of the draught. It is suggested a minimum height of 4 m.
The following features are forbidden and therefore they endanger the good operation of the device: asbestos cement, galvanized steel,
rough and porous internal surfaces. In
The minimum section must be 4 dm
(for example 25 x 25 cm) for devices with diameter greater than 200 mm.
The draught created by the flue must be sufficient, but not excessive.
A too big flue section can feature a too big volume to be heated and consequently cause difficulties in the operation of the device; to avoid
this, tube the flue along its whole height. A too small section causes a decrease of the draught.
ATTENTION: as far as concern the realisation of the flue connection and flammable materials please follow the requirements provided by
UNI 10683 standard. The flue must be properly spaced from any flammable materials or fuels through a proper insulation or an air cavity.
It is FORBIDDEN to let plant piping or air feeding channels pass in the same flue. Moreover, it is forbidden to create movable or fixed
openings on the same for the connection of further other devices
5.1.

CHIMNEY CAP

The draught of the flue depends also on the suitability of the chimney cap.
Therefore, if it is handicraft constructed, the output section must be more than twice as big as the internal section of the flue.
Should it be necessary to exceed the ridge of the roof, the chimney cap must assure the discharge also in case of windy weather
(Picture 6 at page 54 - Picture 7 at page
The chimney cap must meet the following requirements:
• have internal section equivalent to that of the stack.
