Boiler room

Make sure that the room has requirements and characteristics comply with the standards in force.

Also make sure that the oor of the room is suitable to support the weight of the boiler.

E ‘must also drain into the room at least as much air as is required for a normal combustion: you have to practice then,

in the walls of the room, the openings with a free section of at least 6 cm2 per 1 kW (859.64 kcal / h ).

The minimum section of the opening must not be lower than 100 cm2.

The section can be calculated using the following relationship:

S = K * Q ≥ 100 cm2, where “S” is expressed in cm2, “Q” in kW, the “K” = 6 cm2 / kW

These openings must be protected by grates, metal mesh or other suitable protection provided does not reduce the

minimum section, and positioned so as to avoid them being obstructed.

The air ow can also be obtained from a room adjacent to the installation provided that the ow can occur freely

through permanent openings communicating with the non-reclosable outer. The air ow must be smooth and clean air,

unpolluted, and not taken from outlets that may be contaminated (example: garage)

The adjacent with respect to the installation should not be placed in depression respect to the external environment by

means of reverse draft caused by the presence in this space of another used appliance or intake device.

rounded edges with a radius not less than 20 mm, the maximum ratio between the sides of 1.5; walls as smooth as

possible and without restrictions, the regular curves without discontinuities, deviations from the axis no greater than

45 °

- each device must have its own ue of section equal to or greater than the diameter of the ue gas pipe of the stove

and a height of not less than that required

- it is forbidden to make xed or mobile apertures on the chimney to connect equipment other than that to which it is

subservient

- it is forbidden to run inside of the chimney, although oversized, other channels of supply of air and piping for utilities

- it is recommended that the chimney is equipped with a collection chamber for solid materials and any condensates

located below the mouth of the barrel, so as to be easily opened and inspected by the door airtight

- the chimney must have section and internal form equivalent to that of the ue

- the chimney must have a useful outlet section not less than twice that of the ue

- the chimney must be constructed so as to prevent the penetration in the chimney of rain, snow, and foreign bodies

in such a way that in case of winds in any direction or angle is assured the discharge of the combustion products

(windproof cowl)

- the horizontal section should be a maximum length of about 2.3 meters, and you can use a maximum of three 90 °

bends

- in all changes of direction at 90 ° of the chimney must be

possibly a tee with inspection

- all sections of the chimney should be inspected to make possible the periodic maintenance

ue pipe.

Connection to the ue pipe

The ue pipe must have internal dimensions not larger than 20x20 cm, or diameter 20 cm. In the event of larger

dimensions, or of the ue pipe being in poor condition ( for example cracks, poor insulation, etc.), it is advisable to t a

stainless steel pipe of suitable diameter inside the ue pipe throughout its length, right up to the top.

Check with suitable instruments that there is a draught between 6 Pa and 10 Pa. This type of connection ensures the

evacuation of the fumes even in the event of a temporary power cut.

At the bottom of the ue pipe, provide an inspection cap to allow periodic checking and cleaning, which must be done

annually. Make a gas-tight connection to the ue pipe, using pipes and connectors as recommended by us.

You must ensure that a windproof cowl should be tted which complies with the standards in force

Connection to an external ue with insulated or double-wall pipe

The only type of pipe which is permissible is insulated (double-walled) stainless steel, smooth on the inside, xed to

the wall. Flexible stainless steel pipe must not be used. At the bottom of the ue pipe, provide an inspection cap to

allow periodic checking and cleaning, which must be done annually. Make a gas-tight connection to the ue pipe, using

pipes and connectors as recommended by us. You must ensure that a windproof cowl should be tted which complies

with the standards in force.

Check with suitable instruments that there is a draught between 6 Pa and 10 Pa.

dwelling. In the moment in which there is request for

opening a hot water tap, the  ow switch commands

the diverter valve to convey the hot water contained

inside of the boiler towards the plate heat exchanger.

In the case in which the heater is turned off and there

is demand for sanitary water, the heater after 30

seconds from the request, it automatically starts the

ignition process to heat the water inside the boiler

and then to heat the sanitary water.

Directions for use

If the installation of the boiler provides interaction

with another existing system complete with a heater

(gas boiler, gas boiler, oil boiler, etc..) consult quali ed

personnel who can then answer the compliance of

the system, as envisaged by the law in force.

Flushing the system

In accordance with the UNI-CTI 8065 is strongly

recommended to wash the entire system before

connecting it in order to get rid of residues and

deposits.

After  ushing the system to protect it against

corrosion and deposits, it is recommended the use

of inhibitors.

Upstream from the stove, always install shutters so

as to disconnect it from the plumbing system should

it be necessary to move it, or when it requires routine

and/or special maintenance. Connect the boiler using

hoses so that the boiler is not too strictly connected

to the system, and to allow slight movement.

These are as helpful as the supply and return piping

system if the heating system is on a higher  oor than

the boiler.

The exhaust pipe pressure is connected temporarily to

a carafe or a funnel to avoid, in case of overpressure,

that the water gush bathrooms and the structure and

the  oor.

Replenishment of the System

The replenishment has to be slowly carried out

in order to let the air bubbles ow out through

the right oulets that are placed on the heating

system.

In heating systems with a closed circuit the

loading cold pressure of the system and the

ination pressure of the expanding vase must

correspond.

• in heating systems with open vase, the direct

contact between the circulating liquid and the air

is allowed. During the heating-season the user

must regularly check the circulating water level

in the expansion vase.The content of water in

the system of recirculation must be stable hold.

Experiences show that the user must regularly

check the water level every 14 days in order to

maintain a stable water content.

The replenishment process must be carried out

in case of necessity of more water when the

boiler has cooled down.

These preventive measures aim to prevent the

insurgence of thermic stress of the steel body of

The lling pressure of the system when cold

must be 1 bar. During operation, if the system

pressure drops (due to evaporation of dissolved

gases in the water) to values lower than the

minimum indicated above, the user must use

the lling tap to bring the pressure back up to its

normal pressure.

For proper operation of the boiler when hot, the

pressure in the boiler must be 1,1 bar.

the boiler.

• in systems with open vase, the pressure of

water in boiler, when the system is cold, mustn’t

be lower than 0,3 bar;

• the water used to ll up the heating system

must be decontaminate and without air.

The loading valve is required and must be

provided in the hydraulic system.

This operation must be carried out with caution

following these steps:

• open the vent’s valve of the radiator ,of the

boiler and the system;

• Gradually open the lling tap of the system

checking that the automatic vent’s valves,

placed on the system, are regularly working;

• Close the vent’s valves of the radiators as

soon as the air ows out;

• check through the pressure gauge placed in

the system that the pressure is reaching 1 bar

(this is required only for systems with closed

vase, you have to look for local rules that allow

it); whereas for systems with open vase the

restoration will be automatic;

• Close the lling tap of the system and then let

the air ow out again through the vent’s valve

of the radiator;

Filling the thermostove funding of sanitary kit

Once all the water connections, proceed to

check pressure seal by lling the boiler. During

this operation, any air in the system is released

from the automatic vent valve.

You must not mix water of the heating

system with antifreeze or anticorrosion

substances in wrong concentrations.

This could ruin the seals and provoke the

insurgence of noises while operating.

The producer refuses any responsibility for

damages towards persons, animals or things if

this warning will not be respected.

Water Characteristics

The characteristics of the water used to  ll

the system are very important to prevent the

build-up of mineral salts and the formation of

incrustations along the pipes, in the boiler and in

the heat exchangers. Therefore, please get your

plumber’s advice concering:

• Hardness of water circulating in the system, to

prevent problems of incrustation and limescale,

especially in the domestic water heat exchanger

(>25° French).

• Installation of a water softener (if water

hardness > 25° French).

• Filling the system with treated water

(demineralised).

If you have very extensive system, with a large

amount of water, or which require frequent

re lling, it is recommended the installation of

water softening system. It ‘should be noted that

the encrustations drastically reduce performance

because of their low thermal conductivity.

The pellets are cylinders of compressed wood, produced from sawdust and wood

processing (chips and sawdust), generally produced by sawmills and carpenters.

The binding capacity of the lignin contained in wood, allows to obtain a compact

product without adding additives and foreign chemicals to the wood, is

therefore obtained a natural fuel with high yield. The use of expired

pellets or any other unsuitable material can damage parts of the

boiler and impair proper operation: this can lead to the termination

of the guarantee, and its producer responsibility.

For our boilers use pellets diameter 6 mm, length 30 mm

and a maximum of 6% moisture. Store the pellets away from heat

sources and not in humid environments or with explosive atmospheres.

Conﬁ guration of the hydraulic diagram of the boiler

BY A SPECIALIZED TECHNICIAN

Before starting the boiler, it is necessary to con gure the hydraulic scheme on which we want to work. The boiler is set up

to receive the clean contact of an external thermostat (open / closed, the thermostat must not give tension to the back. If

the thermostat carries voltage to the board causing faults, the warranty is void), two temperature probes and a motorized

valve . All these components can be connected via the terminal board on the back of the boiler.

Important considerations:

• healthcare will always have priority

• There are three types of stand-by:

Type 01: the ambient temperature detected by the probe on the board has reached the SET AIR set

Type 02: the water temperature in the boiler has reached the SET H2O set

Type 03: the external thermostat has detected that the desired temperature has been reached and therefore the

contact is open.

In this speci c case the boiler behaves as follows:

If the thermostat carries voltage to the card causing faults, the warranty will expire.
