Connecting To A System With Zone Valves; Hot Water Production Kit (Optional); Operating Conditions; Long-Term Non-Use Conditions - Moretti Design AQUA User Manual

Warning: The exhaust of the safety valve must be connected to a drain
so it can flush out incoming hot water.

Connecting to a system with zone valves

Always leave a zone open. It is advised to have an anti-condensation
valve installed.

Hot water production kit (optional)

On some hydro stove models it is possible to install a kit
on board the appliance for the production of hot water.
This optional feature provides
because everything
controlled by the control unit.
Note: The kit must be connected to the hydraulic system in accordance
with its input and output indications, the maximum admissible pressure is
2 bars (this operation must be carried out by a qualified technician).

Operating Conditions

The hydro stove was designed to be used in normal environments,
where there is no danger of possible fire outbreaks or explosions. The
disposal of combustion waste must be carried out in accordance with
local regulations. While using the hydro stove, the settings cannot be
changed or the protective casings removed. The control unit must be
adjusted by qualified personnel.
The maintenance of the product must be carried out by specialized
companies in the maintenance of heating appliances and authorized by
Moretti Design, who will submit it to all the check ups required by current
regulations.
Use 6 mm diameter and 30 mm average length wooden pellets for
the hydro stove.
Caution: A hydro stove that has been modified or altered, must be
subjected to further verifications in compliance with the law. The
improper connection of the hydro stove heater to the flue and the
non-compliance with standard regulations for the installation of air
vents, can cause serious danger to people.

Long-term non-use conditions

If the hydro stove has not been used for a long period of time, it is
recommended to contact a qualified technician to carry out the following
operations:
- Place the switch in the 0 position
- Close all the valves of the heating and domestic water system
- Empty the system to avoid the water from freezing

Residual Risks

Certain parts of the stove, in particular the glass and flue, while in use
overheat and can cause burns, do not touch or handle unless with the
utmost care.
The electrical parts can cause serious damage, do not touch these parts
without having disconnected the cable from the main power supply.

SAFETY DEVICES

Breakage of the exhaust fan: If for any reason the fan breaks, a safety
measure intervenes and blocks the pellet flow (Er02), an alarm goes off
and stops the stove's function.
Breakage of the auger motor: If the auger motor stops feeding pellet,
the system still continues to function on minimum levels then an alarm
goes off and the stove blocks (Er12, Er03).
Failed ignition: The system foresees 1 ignition attempt, if it is not
successful the hydro stove goes into safe mode then in blocks (Er12).
Check that the burner is clean and well positioned before attempting
another ignition.
If the burner is not cleaned, the next ignition may cause a little
deflagration inside the combustion chamber. If this occurs, the
manufacturer will not accept any responsibility for damage to
persons, animals or things.
unmatched comfort
is completely automatic
On models with the automatic burner cleaning function (PLUS CLEAN),
the burner before each ignition automatically cleans itself, thus avoiding
the user having to open the front door and manually cleaning it.
Electrical protection: The system is protected with a 4 A fuse that is
located on the back of the hydro stove. To replace it, extract the tray next
to the switch only after disconnecting the power cable from the power
supply, replace the broken fuse and reinsert the tray, if the new fuse
immediately breaks, contact a technician.
Exhaust fume safety: If there are any anomalies with the smoke
expulsion from the system, an alarm will go off and the system will block
(Er02).
and
Pellet safety: If the temperature inside the pellet tank exceeds the
safety level, the system blocks (Er01). The reinstatement is automatic,
contact a qualified technician.
Water temperature safety: In case the water temperature in the boiler
exceeds the safety level, the system goes into block (Er01). The
reinstatement is manual and must be carried out by a qualified
technician by pressing the reset button behind the hydro stove.
Breakage of the pump: If the pump stops, the system goes into alarm
and stops (Er01, Er04).
Water pressure safety: The pressure of the system is controlled by an
electronic pressure transducer and must be in between 0,5 bar (50 kPa)
and 1,5 bar (150 kPa), if these conditions are not complied with the
system goes into block. If the system goes over 3 bar, an automatic
safety valve opens and releases the excessive pressure. To regulate the
pressure within the function range, adjust the discharge valve behind the
stove or on the radiator.
Power failure: If there is a short power failure in the power supply, the
system will go into block (Er15), if the lack of electricity is not brief, the
stove could release a small quantity of smoke in the room, if the air
intake has not been correctly connected to the outside. This is caused
by the scarce draw of the chimney flue and does not represent any
risk for one's safety. When the power comes back, the system
switches itself off.
Warning: In the case the chimney catches fire, call the fire brigade.

MINIMUM SAFETY DISTANCES

Keep fuels and flammable substances at an adequate distance from the
stove. For minimum distances from flammable materials, one can refer
to the products identification plate located on the back of the stove.
Caution: For some models the minimum safety distance from
flammable materials may be different than those shown in the
figure below. Therefore, always refer to the product identification
plate generally located on the back of the stove to ensure minimum
safety distances specific model.
Distance in mm
Note: If one wants to install the hydro stove near a non-flammable wall,
it is possible to place it directly in contact with the wall, as long as it does
not obstruct any access to the electrical components or connections or
maintenance interventions.
