2. ASSEMBLING INSTRUCTIONS

The assembly of the pellet stove must only be carried out by an authorised

specialist company. The device must be positioned fixed and safe on a non-

combustible base. It must not be standing tilted on one side (use a spirit

level). The adjustable feet can be used to compensate any unevenness.

2.1 PROTECTING THE BASE AT THE SITE OF

INSTALLATION

The floor must comprise non-combustible material. With combustible floor-

ing (timber, carpet, etc.), a non-combustible underlay made of metal or

ceramic with a minimum thickness of 1 mm or respectively loadable glass

must be provided. In the area of direct radiant heat of the combustion cham-

ber door, the non-combustible layering must be installed at least 500 mm to

the front and at least 300 mm on each side.

2.2 SAFETY DISTANCES

A minimum distance of 150 mm must be maintained to combustible objects

(furniture, decoration, curtains, etc.) positioned on the sides. The safety

distance to the side is reduced to 150 mm with non-combustible objects.

No combustible objects (furniture, curtains, decorations, etc.) may be

placed within a distance of 800 mm in the area of direct radiant heat of

the combustion chamber door or inspection glass. In interest of protecting

furniture or other furnishings, we recommend a distance greater than 1 m.

2.3 CHIMNEY CONNECTION

The pellet stove must be connected to a chimney that has been approved for

solid fuels. Multiple allocation not permitted in the process! The dimension-

ing is carried out according to DIN 4705 / EN13384 when considering DIN

18160 and when using the Technical data specified in 1.2 as a basis.

A continuous supply pressure of 5 Pa to max. 20 Pa is required for a

trouble-free operation. In event of unfavourable operating conditions of the

chimney (e.g., strong drafts, intensive weather-related fluctuations of the

supply pressure, etc.), we recommend the installation of an auxiliary ven-

tilation system. Tip: have the flue gas system checked by the responsible

chimney sweeper in advance.

Direct chimney connection

With a direct chimney connection, the pellet stove can be connected with a

wall distance of 100 mm (see „2.2 Safety distances“). The hole for the wall

lining on the chimney must be located 192 mm above the flooring. A fine

adjustment can be carried out using the height-adjustable feet.

Conventional wall connection

With a chimney orifice positioned a little higher, the wall distance increases

according to the connecting pieces used. In doing so, the longer flue gas

routes as well as several sharp bends of 90° to the connection on the

chimney must be avoided.

The flue gas connection must be carried out air tight as the pellet stove con-

veys the flue gas into the chimney system via the integrated flue gas venti-

lator (in particular during the starting phase) with a slight positive pressure.

Suitable flue pipes are available as accessories (see „1.4 Accessories“).

A respective cleaning opening must also be installed for cleaning the flue

gas path. All transitions must be carried out air tight. Only heat-resistant

sealing agent must be used for sealing.

Flue gas connection

GB 8

In order to establish the flue gas connection, the cladding on the back must

be removed. The rear wall is in two parts. The top part can be hung-out by

lifting it. Then the bottom part can also be removed by lifting it.

2.4 COMBUSTION AIR

Generally, in stoves the combustion air is taken from the installation room.

With this type of air supply, the combustion air connection of the Mellinos

siply stays open.

Attention: it must be ensured that the installation room has a sufficient

supply of fresh air. More detailed information can be found in the country-

specific FeuVO (Fire Ordinance), DIN 18896 or the technical regulations of

the TROL.

The fresh air supply must be checked by the technician and the operator.

When operating several fireplaces in a single room or linked space , ensure

that sufficient air is available for complete combustion! It is possible that

there is not a sufficient supply of fresh air if the windows and doors are

sealed (e.g., in combination with energy saving measures). As a result, the

ventilation of the pellet stove can be affected. If necessary, you have to

ensure for an additional fresh air supply.

Operating an exhaust fan system (e.g., extractor fan, etc.) at the same time

in the same room or linked space with a pellet stove is forbidden due to

smoke or flue gas escaping (despite the combustion chamber room being

closed).

a) Via an external combustion air connection

If the pellet stove Mellino should be supplied with a separate combustion air

line, this must be connected to the flue gas connection (Ø 100 mm) at the

rear (see „1.5 Dimensions“).

When connecting the combustion air neck, the combustion air is supplied

from outside or from other rooms (not from the heating cellar).

In order to ensure for sufficient supply of air, the combustion air line should

be routed with few bends and be no longer than 5 m.

The combustion air openings and lines must not be closed or blocked other

than if it has been ensured that the fireplace can only be operated with

opened fastening by special safety equipment.

The cross-section must not be narrowed by a fastening or a grille. A shut-

off valve must be installed, where the combustion air feed pipe runs outside

the building. In doing so, it must be possible to easily determine the shut-off

valve setting from outside.

In accordance with regulations, combustion air piping crossing a fire protec-

tion wall in buildings with more than two storeys must be established in

such a manner that smoke or fire cannot be transmitted to other floors or

fire compartments. Country-specific and local fire safety regulations must

be observed!

GB 9

2.5 ELECTRICAL CONNECTION

The pellet stove is supplied with an approx. 2 m connecting lead with earth-

ing contact plug. The connection to the power network must only be carried

out on a earthing contact plug installed correctly and earthed according to

VDE guidelines. The mains connection line must be checked for damage at

regular intervals. A damaged connection line must be replaced immediately

by customer services or an authorised person (e.g., electrician).

Note: pull the plug out of the socket before carrying out any work where the

back wall of the device or the side cladding have to be opened.

3. COMMISSIONING AND OPERATION

Commissioning of the pellet stove must only be carried out in a completely

mounted state.

Wooden pellets with the quality specified must only be used as fuel. When

using other fuels, all claims for warranty and guarantee will be rendered

invalid.

Observe all maintenance and cleaning guidelines in order to enjoy an undis-

turbed heating experience.

Further information on commissioning, operating and maintaining the pellet

stove can be obtained in the „Operating instructions Mellino“.

Note: during the first commissioning, the paint of the stove will be burned-

in. This may lead to the development of smoke that is harmless to health,

but has an inconvenient odour. In this case, open the window and vent well.

4. SPECIAL FEATURES OF THE

CONTROL SYSTEM

The control system in the Mellino is characterised by several special

features.

4.1 DIFFERENTIAL PRESSURE CONTROL

The differential pressure control serves to provide constant conditions for

combustion and to compensate and control different chimney conditions at

the place of installation.

In the combustion air channel, a baffle plate made from perforated plate

is installed direct on the combustion air hood. A differential pressure is

measured in front of and behind this baffle plate. The control system is

connected direct to the measuring point using silicone hoses.

The flue gas fan is not given any rotational speeds as parameter, it is given

the value of a differential pressure. Depending on the draught in the chim-

ney, the flue gas fan is controlled so so that the differential pressure is

kept constant. This means that in event of a strong draught in the chimney,

the fan only rotates slowly whereas when the draught is weak, respec-

tively higher speeds are controlled. This creates constant conditions for the

combustion in the burner pot and the pellet stove is independent from the

draught in the chimney at the place if installation to a large extent as the

control system adapts to this.

The differential pressure also detects a complete chimney blockage and

then switches the device off. If the combustion chamber door is opened

during running operation, this is also detected as the differential pressure

now collapses. That is why this pellet stove does not have a door contact

switch. After a timer has elapsed, the extinguishing of the stove is initiated

when the door is opened:

GB 10

4.2 INFINITELY VARIABLE CAPACITY CONTROL

The heating capacity of the stove has been graded 5-fold (see operating

instructions). However, only the parameters for the data for stage 1 (min.)

and stage 5 (max.) are entered. The intermediate stages are calculated

automatically by the control system. The intermediate stages are started-up

softly via ramps and are not switched suddenly. In combination with the flue

gas fan that is also controlled via ramps, this results in a very low noise level

and a simple parameterization, as parameters do not have to be determined

separately for all intermediate stages.

5. OPERATING ELEMENTS

The pellet stove can be operated via the display on the stove. An infrared

remote control is also available for the most important functions:

5.1 THE DISPLAY

The first 3 symbols, at top left, are warnings. Adjacent to these 3 symbols

is the receiver for the remote control unit and a display that shows whether

a timer program is activated. With the menu buttons you can move to the

other 6 displays and then set them.
