WARNINGS AND SAFETY DEVICES The stoves produced by our establishment are built with attention to the individual components in a way to protect both the user and the installer from any accidents. It is therefore recommended that after any intervention on the product, authorised staff pay particular attention to the electric connections, especially the stripped parts of the wires. These must not escape from the terminal board in any situation, thus preventing possible contact with the live parts of the wire.
Chapter 2 WHAT IS THE PELLET? Pellets are realised by subjecting wood shavings i.e. the rejects of pure wood (without paint), sawmill, carpenter products and products from other activities connected to working and transforming wood, to very high pressures. This type of fuel is absolutely ecological as no glues are used to hold it together.
Chapter 2 If installation has been performed using this optional kit, the insert can be extracted or, more comfortably, use the appropriate lateral chute whenever a relevant opening has been made in the covering of the appliance. FRONT PELLET FEEDING OPTIONAL KIT figure 2.1 The use of this optional kit allows to feed the pellets into the feed-box from the front without extracting the flue, therefore without switching it off.
Chapter 2 Take the supplied Allen wrench, insert it into the relevant seat FIRE IRONS and turn in an anti-clockwise direction until fully home. If this operation has been carried out correctly the drawer will be blocked and cannot be moved forwards or backwards. At this point, take the internal drawer and pull it towards yourself to maximum opening: carry out this operation by attaching the two fire irons to the lateral holes in the drawer.
Chapter 3 ASSEMBLY AND INSTALLATION INSTRUCTIONS The installation must comply with: UNI 10683 (2005) heat generators fed with wood and other solid fuels: installation. The chimneys must comply with: UNI 9731 (1990) chimneys: classification according to thermal resistance. EN 13384-1 (2006) calculation method of the thermal and fluid-dynamic features of the chimney. UNI 7129 point 4.3.3 provisions, local rules and prescriptions of the fire brigade. UNI 1443 (2005) chimneys: general requirements.
Chapter 3 EXHAUST VENTING SYSTEM A system for fume exhaust venting that is independent from the appliance, composed of a pipe or channel, chimney or single flue, and chimney cap. FORCED DRAUGHT Air circulation by means of a fan driven by an electric motor. NATURAL DRAUGHT Draught resulting in a chimney/flue due to the difference in the volume mass existing between the (hot) fumes and the surrounding atmospheric air, without any mechanical suction aid installed inside or on top of it.
Chapter 3 CONNECTION TO THE EXHAUST VENTING SYSTEM EXHAUST CHANNEL OR PIPE For the assembly of the exhaust channels it is imperative to use non-flammable materials that are resistant to combustion products and any condensates. It is forbidden to use flexible metal pipes and asbestos cement for connecting the stove to the flue, also for preexisting exhaust channels. There must be continuity between the exhaust channel and the flue so that the flue does not lean on the stove.
Chapter 3 the flue connection. It is forbidden to run other air feed channels or piping for utilities inside the exhaust channels, even if they are oversized. It is also forbidden to fit manual draught adjustment devices on the forced draught appliance.

Chapter 3 CONNECTION TO THE FLUE AND COMBUSTION PRODUCT EXHAUST VENTING The flue must receive exhaust from a single heat generator. Direct discharge towards enclosed areas, even when roofless, is forbidden. Direct discharge of combustion products must take place on the roof and the exhaust duct must have the features set forth in the section “Chimney or single flue”.

Chapter 4 COMFORT PLUS INSTALLATION The Comfort Plus model is supplied with an iron sliding base that allows to install it in a pre-existing flue. This sliding base allows the easy extraction of the insert both for pellet feeding inside the feed-box and for any maintenance or cleaning at the end of the season. If there is no pre-existing flue, one can be built using the insert-holder pedestal (optional kit); in fact, the latter fixes the insert to the floor.
Chapter 4 The air vent must be made outside the flue as it must not suck heated air. Fix the base using the locking screws. Connect the conveyor pipe correctly to the piping for flue evacuation, the air vent box to the relative intake pipe and the conveyor to the ducting piping. Re-position the machine body by repeating the operations carried out previously in the reverse order. Finally, use the Allen wrench to turn the lockbolt anti-clockwise to block movement.

Chapter 4 AIR CIRCULATION PIPES It is necessary to create air recirculation inside the structure that covers the insert for correct functioning. This prevents the appliance from over-heating. To guarantee this, just realise one or more openings in the lower part and in the upper part of the covering. The following measurements must be respected: Lower part (cold air inlet) D total minimum surface 600 cm2. The openings in the lower part must be realised below the rest bottom.
Chapter 4 60 mm figure 4.7 35 mm 35 mm figure 4.
Chapter 4 86 Hot convection air The heat accumulated inside the covering must be vented to prevent excessive over-heating of the insert Forced ventilation The tangential fan distributes the heat developed by the insert into the environment. Air inlet from the environment To allow air recirculation an air inlet point must be envisioned, which is preferably positioned in the lower part of the structure in order to favour convection. The air must be withdrawn from the machine’s working environment.
Chapter 4 Air intake box figure 4.10 Air intake box figure 4.11 Regarding the air intake box, it is possible to apply the intake pipe above the base (see figure above) or below (see figure below) depending on requirements. These operations must be carried out by an authorised technician.
Chapter 4 DUCTING The insert has a pipe in the rear part that allows ducting of the heat developed by the machine. It is recommended to perform ducting using the piping that reflects the following specifications: internal diameter 80 mm insulated piping, The tract of pipe connected must not exceed 2m. figure 4.12 figure 4.13 figure 4.14 The insert is supplied with a ducting pipe, closed by a metal clamp: before connecting the piping, remove the plate and re-mount the screws to close the holes.
