c) Extinguish the fire using carbon dioxide fire-fighting means (CO
d) Seek immediate intervention of FIRE BRIGADE.
DO NOT EXTINGUISH FIRE USING WATER JETS. When the flue does not burn any more please arrange an examination by a
specialist in order to find possible cracks and permeable points.

BEAM PROTECTIONS

Considering the irradiation of the hearth, it is necessary to be particularly careful in protecting the beams while designing your stack.
Consider the proximity of beams to the external surfaces of the hearth, on one side, and the irradiation of the glass door, usually very
close to the beams, on the other side. In any case, it has to be considered that the internal or lower surfaces of this beam in flammable
material must not come in contact with temperatures higher than 65 °C.
WARNING: We cannot be made liable for a wrong operation of the plant, when it does not comply with the provisions
of these instructions or when it uses additional products not suitable for this device.

DESCRIPTION

Definition: thermo-fireplace according to EN 13229.
La NORDICA thermo-fireplace are ideal for holiday flats and weekend houses or as auxiliary heating all year round. Wooden logs are
used as fuel. The appliance works as an intermittent operating appliance.
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. A swivelling, removable grid is found inside the
fireplace (Picture 12 pos. A). Ash drawer
The sight door is assembled on extensible ball guides, which assure a robust and silent operation reliable in time. The door lifting
counter-weight is supported by two sturdy chains with related 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.
WF25 - WF25X - WF25 Plus
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.
The primary air register must be almost completely closed during wood combustion, as otherwise the wood burns too
quickly and the thermo-product may 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:
