FLUE CONNECTION or DUCT: duct or connection element between the unit and flue for evacuation of fumes.
DUCT technical requirements: - it must not cross rooms in which the installation of combustion units is not allowed;
- flexible metal tubes or fibre cement pipes are prohibited;
- the use of counter-sloping elements is prohibited;
- horizontal sections must have an upward slope of at least 3°;
- the length of the horizontal section must be minimal and not more than 3 m;
- there must not be more than 3 changes of direction, without the T union;
- with change of direction > 90° a max. of 2 bends can be used with length in horizontal projection not exceeding 2 m.
- the fume duct must have a constant section and allow the recovery of soot.
CHIMNEY CAP : a device placed on the top of the flue to facilitate the dispersion of fumes into the atmosphere.
CHIMNEY CAP technical requirements : it must have a section equivalent to that of the flue;
- it must have a useful section not less than double the internal section of the flue;
- it must prevent the entry of rain and foreign bodies and ensure the discharge of fumes in any
atmospheric condition;
- it must ensure an adequate dilution of fumes and be positioned outside the backflow area;
- it must be without mechanical means of suction.
- The direct discharge of the fuel products must be at roof and is forbidden to confined spaces, even with clear sky.
-
With
the standard installation displayed in picture 2.3 the stove is configured with the debimeter on while on the
installation in picture 2.4 the technician must deactivate such component and reset the stove's parameters.
- The installation must be performed by qualified personnel, who will assume full responsibility for the installation and
its operation of the installed.
2.5 Brazier and baffle position check
Before lighting the stove make sure the brazier is in the correct position, i.e. fitted in the special slots. Also make
sure the top smoke baffle is properly fitted. A wrongly positioned baffle can result in malfunctioning and excessive
blackening of the glass.
At every stove lighting, check the correct position of the brazier on the brazier holder.
2.6 Electrical connection
Connect one end of the power cable the wall socket.
The voltage supplied by the system must match that specified on the stove dataplate and in the technical data
section of this manual. Plug the device power cord must be connected only AFTER the end of the installation and
assembly of the device and must remain accessible. During stove idle periods it is advisable to remove the power
cable. (wiring diagram fig.3)
- Make sure the electrical system is equipped with an earth and differential switch in accordance with the current
Regulations.
- The power cable must never touch the stove exhaust pipe.
2.7 Wiring diagram for zone system
Before installing the heating stove in the house, check the type of heating system; in case of several zones, a
special electronic controller for multi-zone circuits, available as an optional, must be installed. This is to prevent
overheating of the heating chamber due to possible simultaneous closing of the zone valves and consequent
stopping of hot water flow.
2.8 Plumbing connections
The heating capacity of the unit must be previously established by calculating the building's heat requirement
according to current regulations. The system must be provided with all the components for correct and regular
operation; in fact according to the rules of proper workmanship in installation, shutoff valves and non-return valves
allowing the stove to be isolated in case of maintenance and/or checks, must be interposed between the stove and
the heating system.
Proceed slowly during heating chamber water filling, to allow correct and complete evacuation of the air from the
vent ( for a closed vessel system from 1.1 to 1.5 bar ).
The pellet stove has an internal heating circuit complete with circulating pump, safety valves, air vent, temperature
probes and pressure transducer.
If the heating system is managed in zones a multi-zone controller, available on request, must be installed.
To display the boiler's water circuit pressure, just press the control panel button P5 scroll menu select 8 select with
button P5 and check info with buttons P1-P2 .
To connect the stove to a heating system it is advisable to contact a competent technician in order to best optimise
the plumbing connections and the performance of the entire system without compromising stove operation (rif.fig.4).
During insert transport the gaskets in the plumbing system may come loose and/or break, causing water leaks during
normal operation; therefore make sure to check the tightness of the circulating pump and heating chamber
connection rings and vent the residual air during water filling and after the first hours of operation.
