5. DESCRIPTION

Denition: thermo-replace according to EN 13229.

La NORDICA thermo-replace are ideal for holiday ats 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 replace 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 replace. A swivelling, removable grid is found inside the replace

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-

replace;

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 (Picture 9 at page 81)

With the air register located under the door of the hearth, it is possible to adjust the air ow through the ash drawer and the grating in

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 caloric yield is the following one:

6. FLUE

Essential requirements for a correct operation of the device:

Should the ues 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.

4.2. 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 ammable material

must not come in contact with temperatures higher than 65 °C. Picture 3 at page 77 gives some examples of execution.

WARNING: We cannot be made liable for a wrong operation of the plant, when it does not comply with the provisions of these
