placed in rooms which are protected from frost. On the contrary, if they freeze, the boiler body could break or even explode. In case

of frost placing it will be right to add a proper percentage of antifreeze liquid to the water of installation in order to delete the whole

problem. In no way there must be water circulation in the open expansion tank between the safety and loading pipe. This would cause

the water oxygenation and the consequent corrosion of thermo-product and installation in a very short time.

4. THERMAL DISCHARGE VALVE which is a further positive safety that prevents the boiling even when electric energy

is missing. It is made by a valve cover like a pressure safety valve which differs from it as it opens by reaching a pre-calibrated

temperature (normally at 94 – 95°C) and unload hot water from the installation delivery. This will be replaced with as much cold water

oxygenation with consequent, fast corrosion of boiler body. It must be not to avoid a forced circulation in the open expansion tank.

Furthermore it must be electrically connected to a thermostat or a electronic control unit that can be purchased with the thermo-

replace as OPTIONAL part.

8. ANTI-CONDENSATION MIXING VALVE – (see chapter 2.2)

ATTENTION: temperature safety sensors must be in place on the machine or at a distance no greater than 30 cm from the ow connection

of the thermo-product. Whenever the thermo products lack a device, those missing can be installed on the thermo product ow pipe,

within a distance no greater than 1m from the thermo product. All those parts must no have for any reason meditate intercept bodies

that could accidentally exclude them and must be placed in rooms which are protected from frost. On the contrary, if they freeze, the

boiler body could break or even explode.

ATTENTION: For no reason must the re be ignited before the system has been completely lled with water; doing this would

Picture 1 at page 47. Routes 1 and 3 are always open and, along with the pump installed on the return (R), they guarantee water circulation

inside the biomass boiler exchanger (CB). An elevated return temperature, allows efciency 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 opens and the boiler water goes to the system via the ow (M).

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

2.3. SYSTEM CONNECTION AND FILLING

Some examples, purely indicative of the installation, are reported at chapter INSTALLATION LAY-OUT, while the connections to the

thermoproduct are reported at chapter DIMENSIONI.

unpleasant oodings.

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-product is not used. During winter season the non use has

to be faced by adding antifreeze substances.

3. FIRE-FIGHTING SAFETY MEASURES

When installing the appliance, the following safety measures must be observed:

a) In order to ensure sufcient thermal insulation, respect the minimum safety distance from objects or furnishing components ammable

and sensitive to heat and from materials with ammable structure (see CE MARKING INFORMATION). All the minimum safety

distances are shown on the product data plate and lower values must not be used.

b) in front of the furnace door, in the radiation area, there must be no ammable or heat-sensitive objects or material at a distance of

The ash drawer must always be inserted when the appliance is in operation.

The solid combustion residues (ashes) must be collected in a metal container that is hermetically sealed and re resistant. The appliance
