or by using a bracelet thermostat immediately installed on the delivery and calibrated at the
mentioned 65-70° C.
8. AUTOMATIC THERMOSTATIC VALVE – Picture 17
The automatic thermostatic mixing valve is used in the solid fuel thermoproducts as it prevents that
cold water returns into the exchanger.
The ways 1 and 3 are always open and together with the pump installed on return ( R) they
guarantee water circulation inside the exchanger of biomass boiler ( CB ).
A high return temperature allows to improve efficiency, reduce smokes condensation and lengthen
the boiler life.
The valves in the market show different calibrations. La NORDICA suggest to use the 55° C model
with 1" hydraulic connections. Once the valve calibration temperature is reached, the way 2 opens
and the boiler water goes through the delivery ( M ) to the installation).
IMPORTANT: if the device is not installed there will be not any guarantee on heating exchanger.
IMPORTANT: the temperature safety probes mut be inside the machine or at 30 cm max from the
thermoproduct delivery connection.
Should the generators not provided with all devices , the missing ones can be installed on the
thermoproduct within a distance of not more than 1 m from it.
ATTENTION: for no reason the fire shall be lightened before the installation is completely full of
water otherwise there will be a serious damage to the whole structure.
We recommend providing an inspection door on the counterplate or elsewhere as suitable to provide easy
accessibility and visibility of the safety devices (pressure gauges, valves) .
8.1. SYSTEM CONNECTION AND FILLING – Chapter 18
On the right and left-hand sides of the thermo-fireplace there are couplings for the hot water in output
delivery (upper part) while on the lower part there are those in return.
WE RECOMMEND USING AN "INTERSECTING FLOW" INSTALLATION (DELIVERY ON THE RIGHT
WITH RETURN ON THE LEFT, OR DELIVERY ON THE LEFT WITH RETURN ON THE RIGHT).
ATTENTION:
The filling of the system must take place exclusively by the natural fall of the water from the open
expansion tank through the feed pipe in order to avoid that a too high water system grid pressure
could change or cause the explosion of boiler body.
During this phase, open all the bleed valves of the radiators to prevent the formation of air sacks, checking
the outlet of water to avoid unpleasant floodings.
The watertight test of the installation is performed with the pressure of expansion tank open.
The installation must always be full of water even when the thermo-fireplace is not used. During
winter season the non use has to be faced by adding antifreeze substances.
