Description of the hydro stove
The pellet hydro stove is a heat source that can heat water, which is
then pumped into a closed expansion vessel system, by burning wooden
pellets. The fuel is loaded automatically into the hydro stove. The hydro
stove has been designed to use a heat transfer fluid (water). The water
inside the stove is heated by the flames produced by the combustion of
wooden pellets and then pumped into the heating system.
The safe use of the hydro stove is guaranteed by the fact that on all
MORETTI DESIGN products, CE certified systems are installed and they
control all functions and parameters, including the possible clogging of
the chimney flue. The advanced software allows for the user a more
simple and immediate comprehension of the hydro stove functions. The
presence of a thermostat on all MORETTI DESIGN products allows the
user to program the on/off switching function of the hydro stove. The
large fuel tank, allows fuel fillings conveniently diluted over time. The
large ash draw allows the user to empty it just once a week when it is
filled with ash (The frequency of the operation may vary depending on
the time of use of the stove and quality of pellets).
INSTALLATION
The hydro stove must be placed on a floor with an adequate load
capacity. If the building does not meet this requirement, appropri-
ate measures (e.g. load distribution plate) must be taken.
The installation of the hydro stove must ensure an easy access for
cleaning the heater, the flue and the chimney.
The presence of extraction fans in the same room or environment
where the appliance is installed in, can cause problems and should
therefore be avoided.
It is prohibited to install the stove in a small rooms or bedrooms. It
is forbidden to install the stove in rooms exposed to a high risk of
fire, in rooms with an explosive atmosphere or where other heat
generators are already present whose simultaneous presence is
not compatible according to standard regulations. The installation
in small rooms or bedrooms can take place only if the stove is her-
metic (hermetic system) and
air required for the combustion must
be drawn directly from the outside through a tube.
All local regulations and European standards must be met when the
stove is installed.
Supply conditions and Unpacking
The hydro stove is delivered packaged together with the dismantled
aesthetics. To unpack the hydro stove it is necessary to cut the straps
and remove the carton. Use the proper equipment for lifting the appli-
ance from the wooden pallet.
Assembling
For the installation of the MORETTI DESIGN hydro stove,
contact an authorized technician (the penalty otherwise
would be the void of the warranty).
Combustion air
A poor combustion can be caused by poor air circulation in the room and
this often occurs in modern homes that have sealed doors and windows.
The situation also becomes problematic when, on the contrary, there are
air currents inside the room (generated for example by fans). To avoid
this type of disadvantage, it is recommended to install a permanent ven-
tilation grid in a window or near the stove.
The air required for the combustion must be drawn directly from the
outside through a tube with a
60mm
diameter. The tube must not exceed
5m
in length and must not have more than
4 curves with a 90°
angle. It
is recommended the installation of an air grid over the opening and it
must be kept clean (see the following example).
If there is no possibility of connecting the air intake directly to the outside
(see next paragraph), it is imperative to drill a hole on the wall for the
combustion air inlet for both health and safety reasons. It is recommend-
ed the installation of an air grid over the opening and it must be kept
clean.
Fume exhaust
To extract the exhaust fumes, a flue must be installed in compliance with
standard regulations. The stove was not designed to share the flue with
other appliances.
