TERMOROSA TR-02 - Narvells

Wood burning stove/cooker – TERMOROSA TR02
In no way should water circulate in the small tank in-between the safety pipe and load pipe, seeing as
this oxidises of the water and consequently this quickly corrodes the thermo cooker and system body.
4. HEAT DISCHARGE VALVE: permits an extra positive safety, capable of preventing boiling, even if
there is no electric power.
It consists of a valve, similar to a pressure safety valve, but differs, seeing that it opens once the precalibrated
temperature (normally 94-95°C) is reache d. It discharges hot water from the system flow
pipe, and the water is replaced with the same quantity of cold water, supplied from the tank vessel load
pipe, this way reducing the excessive heat.
5. SAFETY VALVE FROM 1,5bar: maximum operation pressure allowed for the system is 1,5 bar (equal
to 15m of the water column). Higher pressures can cause deformation and breakage of the boiler body.
6. SAFETY DEVICES envisioned by Regulations in vigour.
7. CIRCULATION PUMP: preferably fitted on the return pipes to avoid diffusion of extremely high
temperature water, however ensure that it does not make water circulate in the open vessel tank as this
would cause continuous oxidation of water which would quickly corrode the boiler body.
It must also be connected electronically so that it will only work when the water temperature reaches
65-70°C. To achieve this one can use the electronic control unit, available as an OPTIONAL with the
thermo cooker, or by using a sleeve thermo switch fitted directly on the flow pipe and calibrated at 65 -
70° C.
8. AUTOMATIC THERMOSTATIC MIXING VALVE - Picture 2
The automatic thermostatic mixer valve finds applications in solid fuel heat generators as it prevents
cold water return in the exchanger.
Routes 1 and 3 are always open and, along with the pump installed on the return (R), the guarantee
water circulation inside the biomass boiler exchanger (CB).
An elevated return temperature, allows efficiency improvement, reduces formation of smoke
condensation and prolongs the boiler life span.
Valves on the market have different calibrations. NORDICA advises use of model 55°c with 1"
hydraulic connections. Once the valve calibration temperature is reached, route 2 is opened and the
boiler water is goes to the system via the flow (M).

IMPORTANT lack of installation of the device voids the heat exchanger warranty.

IMPORTANT: temperature safety sensors must be in place on the machine at a distance no greater than
30 cm from the flow connection of the thermo-product.
Whenever the thermo products lack a device, those missing can be installed on the thermo product flow
pipe, within a distance no greater than 1m from the thermo product.
ATTENTION: For no reason should the fire be lit if the plant has not previously been completely
filled with water. Doing so would seriously damage the entire structure. Filling the
plant must be done via the load pipe direct to the open vessel tank, in a manner that avoids
an excessive pressure of the water network deforming the thermo cooker boiler body. .
The plant must always be full of water even during periods when the thermo cooker is not used. During
winter, an eventual period of rest must be met with the addition of antifreeze.
