3 –GENERAL DESCRIPTION
3.1 OPERATING TECHNOLOGY
Your generator has been built to fully satisfy all your heating and practical requirements. Top-grade components and functions
managed with microprocessor technology guarantee high reliability and optimal performance.
LAMBDA EVO5 uses reverse flame technology. The flame is drawn to the lower part of the boiler through the action of a suction
device. The flame develops in the cast iron burner and the particular shape of the flame determines low emissions and an optimal
smooth running.
3.2 WOOD FUEL
The only fuel permissible for use in this appliance is wood logs having a maximum length of 500 mm and moisture content below
20%.
Pay special attention to the characteristics of the wood: like all biomass generators good performance of the generator depends on
the type of wood used and on its degree of seasoning.
Wood after one year of drying: still contains 40% moisture and generates an average 2000/2200 Kcal per Kg.
Wood after two years of drying: still contains an average of 25% moisture and generates approx. 3000 Kcal per Kg.
Wood after three years of drying: still contains an average of 15% moisture and generates approx. 3500 Kcal per Kg.
Store firewood correctly, preferably raised from the ground and protected from sources of moisture or humidity and the weather.
Excellent quality: ash, beech, maple, hornbeam, oak. Average quality: birch, alder and acacia.
Satisfactory quality: lime, poplar, willow, chestnut (only with a minimum seasoning of two years to reduce the tannin content), fir,
larch. Other types of resinous woods are not suitable.
The wood should be cut as close as possible to the length of the combustion chamber in such a way as to completely cover the
burner base and also to obtain a heavier load for a longer duration.
The logs must be placed parallel, next to each other, in order to leave the fewer gaps possible. To achieve the rated power the fuel
load must sit on a bed of embers that does not exceed a thickness of 5 cm. Using larger logs could reduce the generator power.
The maximum thermal value is achieved by using fuel having a diameter of 5/7 cm.
Use of fuel other than all-wood logs is forbidden. The use of fuel other than all-wood logs immediately voids
the appliance warranty. Do not use the appliance as an incinerator, at the risk of voiding the warranty.

4 –INSTALLATION
4.1 APPLIANCE LOCATION
Follow the general guidelines set out in paragraph 1.1 to the letter. Keep in mind that the flooring of the room in which
the appliance is to be installed must withstand the combined weight of the appliance, the fuel, and the water
contained in the appliance.
ATTENTION: The room where the appliance is installed must be well-ventilated and
free from humidity and salty air. A high level of humidity or saltiness in the room can
lead to the onset of rust or corrosion which will not be covered by warranty.
If inflammable materials are located in the vicinity of the appliance (e.g.: match-
boarding, furniture, curtains, pictures and paintings, sofas) it is mandatory to comply
with the minimum distances illustrated (see figure at right)
Installation in the vicinity of heat-sensitive materials is only permitted if suitable
insulating and fireproof protection is placed between the object and the appliance
(ref. Uni 10683). If the flooring is made of wood or any other combustible material, it
is mandatory to install a fireproof floor protector plate between the appliance and the
floor. Installation in the vicinity of heat-sensitive materials is only permitted if suitable
insulating and fireproof protection is placed between the object and the appliance
(ref. Uni 10683). Failure to observe this instruction will immediately invalidate the
warranty.
The installer must issue a certificate of conformity for the installation which includes the design plans and the
following documents:
a) Report containing the type of materials utilised.
b) Project as defined in Article 5 of Ministerial Decree n° 37 22 January 2008.
d) References to existing partial or previous declarations of conformity (e.g. electrical wiring).
e) Copy of the certificate of recognition of the professional technical qualifications.
These documents must, by law, be kept together with the use and maintenance booklet. The customer is responsible
for verifying, directly or indirectly, that the installation has been carried out to perfection in accordance with relevant
regulations in force. Do not install the appliance in unsuitable rooms such as bedrooms, bathrooms, garages and/or
lock-ups. It is forbidden to place the appliance in environments with an explosive atmosphere.
ATTENTION, the appliance is not simply a household appliance: if the instructions set out in this booklet are not
followed and/or if installation of the appliance is not executed perfectly and/or the provisions in force are not strictly
complied with, dangerous conditions could arise for both objects and persons. It is the user’s responsibility to verify
the presence, in the room, of a vent necessary for supplying oxygen to the generator.
The installer must provide the final user with verbal instructions on the correct use of the appliance when the
appliance is set at work for the first time.

4.2 INSTALLATION OF THE SAFETY HEAT EXCHANGER (OPTIONAL)
The safety heat exchanger is mandatory in closed expansion tank systems. Installation of the safety heat exchanger requires
removal of part of the casing. Follow the instructions below to perform this operation. By installing the approved thermal relief valve
the safety heat exchanger absorbs the excess heat in the boiler, due to external causes, as soon as it rises to excessively high
temperatures. This function is called fast disconnection phase.
IF THE SAFETY HEAT EXCHANGER IS INSTALLED TO PRODUCE DOMESTIC HOT WATER THE
GUARANTEE FOR THE GENERATOR IS IMMEDIATELY VOIDED.
INSTALLATION OF THE SAFETY HEAT EXCHANGER MUST BE CARRIED OUT BY A QUALIFIED
PROFESSIONAL AND IN COMPLIANCE WITH APPLICABLE REGULATIONS.

7) Fasten the two inlets with the Kit supplied with the heat exchanger and following the order indicated in the figure below:
8) Install the certified and calibrated two-way thermal relief valve at the exchanger inlet, following the instructions provided by
the manufacturer and install a discharge pipe.
The thermal relief valve must have the following characteristics:
- Double safety sensor for solid fuel generators
- Max working pressure: 10 bar
- Temperature range: 5÷110°C
- Calibration temperature 98°C
- Discharge capacity with Δp = 1 bar and T=110°C: 3000 l/h
- Capillary tube length: 130 mm
- Certified to standard EN 14597
Lastly insert the sensitive element of the thermal relief valve by removing the pocket (M) and screwing in the pocket
supplied with the valve.
ATTENTION: before reassembling the remaining parts make sure that the gaskets are tight by bringing the system to
pressure.
9) Reassemble the parts by carrying out the above procedure in reverse order.
ATTENTION: A CONNECTION MUST BE MADE BETWEEN THE SAFETY VALVE AND THE OUTLET TO
PREVENT DAMAGING MATERIALS SURROUNDING THE BOILER WHEN THE VALVE IS ACTIVATED. IT IS
MANDATORY TO INSTALL A T UNION WITH TAP FOR DISCHARGING FROM THE BOILER.

4.3 RELOCATION OF THE SPIRAL TUBE SCRAPER LEVER
The product is supplied with the spiral tube scraper lever mounted on the right side; if needed, it can be moved to the left side of
the appliance.
This operation must be exclusively performed by qualified professional staff, as set forth by Decree no. 37 of 22nd
January 2008 and applicable laws on the subject. Before performing said task, make sure the power supply cable is
disconnected from the electrical power socket.
Follow the procedures in the previous chapter up to point 2 to carry out this operation.
4.4 GUIDELINES FOR THE HYDRAULIC SYSTEM
The hydraulic system must be installed by qualified personnel who are familiar with the standards mentioned
above and who have the appropriate professional requirements to release the declaration of conformance in
accordance with Ministerial Decree n° 37 of 22 January 2008. The system must be suitably sized in relation to the
power of the generator.
ATTENTION: it is mandatory to earth the generator. If this instruction is not observed serious damage, which is
not covered by warranty, will result to the body of the appliance. Have a skilled electrician check the earthing.
There must be no electric potential (Volt) between the generator earth and the plant’s real earth (earth plate). To
prevent electrochemical corrosion of the appliance body do not use galvanised pipes and fittings. Other materials
must be earthed with special earthing cables in order to obtain a unipotential earthing system.
4.5 INSTRUCTIONS FOR EXECUTING THE CLOSED EXPANSION TANK HYDRAULIC SYSTEM
To install the system with a closed expansion tank refer to the requirements laid down in EN 10412-2:2009 for appliances with
nominal heat output not exceeding 35 kW or in the Ministerial Decree Collection R edition 2009 for appliances with nominal heat
output exceeding 35 kW.
The hydraulic system must be installed by qualified personnel who are familiar with the standards mentioned above and who have
the appropriate professional requirements to release the declaration of conformance in accordance with Ministerial Decree n° 37 of
22 January 2008.
A closed expansion tank must be series-connected to the generator as protection for the system.
The nominal volume of the closed expansion tank must be sized in relation to the total volume of the water contained in the system.
Thermorossi prescribes the size of the closed expansion tank as equal to 10% of the volume of water contained in the entire
system. Any bulging of the boiler body caused by an incorrectly sized expansion tank will not be covered by the warranty.
The next chapter and the preceding chapters do not replace the above mentioned standards to which they refer. The qualified
installer must in any case be fully aware of the above standards and their amending versions.

1 motor-operated anticondensation unit 70030783
1 safety heat exchanger Code 60013727
1 thermal relief valve Code 60012922
When any alarm intervenes - except the ‘door open’ or ‘boiler temperature too high’ alarms - the generator enables the start
consent for an auxiliary generator.
The auxiliary generator receives the signal to start when contacts 1 and 3 on terminal block JP4 close. These contacts are not
powered and therefore are defined as voltage-free contacts.
With this type of system, you must activate the BOILER + PUFFER TANK configuration in the generator’s System Menu. (See the
paragraph dedicated to software operation).
ATTENTION: it is mandatory to earth the generator. If this instruction is not observed serious damage, which
is not covered by warranty, will result to the body of the generator. Have an electrician check the earthing.
