TRANSPORTATION AND HANDLING The boiler body must always be in a vertical position when handled and exclusively by means of trolleys. Take special care to protect the electric panel, the glass, the ceramics and all the fragile parts from mechanical impact which could damage them and their correct functioning. STORAGE : The heater / boiler must be stored in a humid-free environment and sheltered from the weather; do not place the heater / boiler directly on the floor. The Company denies all responsibility for damage caused to wood floors or floors made from any other material. It is inadvisable to store the heater / boiler for long periods of time.

Caution: it is mandatory to earth the heater / boiler. If this instruction is not observed serious damage, which is not covered by warranty, will result to the body of the heater / boiler. Have an electrician check the earthing. there must be no electric potential (volts) between the earth of the generator and the actual earth of the plant. To prevent electrochemical corrosion of the boiler body do not use galvanised pipes and fittings.Dedicated ground wires must be used to ground all other materials.

PELLETSPELLETS

PELLETS

•The appliance is fuelled by pellets, that is, cylinders of compressed sawdust; this will make it possible for you to enjoy to the full the flame without having to manually stoke the combustion.

•The pellets are cylinders of compressed sawdust having a 6 mm diameter and a maximum length of 15 mm. They have a maximum moisture content of 8%, a thermal value of 4000/4500 Kcal/Kg and a density of approx. 620-630 Kg/m³.

The use of fuel which does not comply with the description given above immediately voids the heater / boiler warranty. Do not use the appliance as an incinerator, at the risk of voiding the warranty.

THE FEEDBO

The feedbox is situated in the top part of the heater / boiler. The maximum load capacity of the tank is approximately 43 Kg, but varies according to the specific weight of the pellets.

The manufacturer recommends emptying the hopper and vacuuming the screw feeder zone once a month and during the summer period. Take special care when loading the hopper as the screw feeder at its base is in motion.

CAUTION: Always use trolleys to move the appliance and the appliance must always be in a vertical position. The casing for the H2O is packed separately . On the contrary, to unpack the Compact, once the wood crate has been removed, remove the casing (in reverse order as set out in par.4.2.3). Remove the screw at the base of the heater / boiler and remove the base from the bottom pallet. Follow the general guidelines set out in paragraph 1.1 to the letter. Above all ensure that the flooring of the room where the heater / boiler will be installed is capable of bearing the weight of the appliance plus the weight of the water contained in it and the weight of the pellets in the hopper. CAUTION: The room in which the appliance will operate must be adequately ventilated (minimum air intake for an air flow of 1300 m3/h).

The heater / boiler must be positioned at a minimum safe distance from walls and furnishings. This distance will have to be increased considerably if the objects surrounding the appliance are inflammable (matchboarding, furniture, curtains, picture frames, sofas, etc...). The recommended minimum distances are illustrated in the drawing below on the right. Installation in the vicinity of heatsensitive materials is only permitted if suitable insulating protection is provided for ( ref. Uni 10683).

After positioning and levelling the heater by raising or lowering the mounting feet, connecting it to the heating system and to the electrical system, the next step is to mount the casing as shown in the image:

Carry out the steps described below as illustrated in figures 1,2,3:

- Open the pellets feed cover and remove the screws (C) (Figure 1).

- Remove the complete cover (B) (Figure 1).

- Next undo the first 2 screws (L) then remove the side panels (I) (Figure 2).

- Next fix the ceramic tiles on the side (G) as shown in Figure 3. Take care not to over-tighten the nuts (F) as this could cause the tile to break<>; this type of damage is not covered by warranty.

- After fixing the 4 ceramics proceed to mount the side panel (I) (Figure 2).

-Reassemble the complete cover (B) by fixing it with the screws (C) then place the ceramics (A).

- Firstly remove the protective film from the casing.

- Next mount the 2 side panels (F) by inserting the 2 holes of the bottom fold on the pins of the base and fastening the 2 top screws with a screwdriver.

- Fasten the front cover (C) by fitting it onto the side panels.

- Fasten the door (P) to the left side with the special hinges and screws provided.

- Lastly fit the back cover (CP) on the front cover (C) and fasten the hinges with the screws provided.

If you prefer the door (P) can be mounted with the handle on the left and the hinges on the right. Simply remove the handle (M) from the door and fix it to the holes on the left side of the door, remove the hinges (T) and fix them to the right side of the door. Similarly, remove the magnet from the right side of the door and mount it on the left side of the door.

After positioning and levelling the boiler by raising or lowering the mounting feet, connecting it to the heating system and to the electrical system (see para. 4.4, 4.5, 4.6, 4.7, 4.8 and 4.9 ),proceed to mount the casing as illustrated:

To increase the boiler's autonomy of operation it is possible to install one or two additional hoppers at the sides of the boiler. Each additional hopper can hold up to 100 Kg of pellets. Firstly unpack the hopper then assemble it as follows:

- Fasten the 4 telescopic legs (A) using the screws provided (screws TSP+ 8x50).

- Fasten the pellet chute (attention: use chute B1) to the hopper using the screws provided (screws TC+4.8x13).

- Mount the panel (C) by inserting the bottom folds on the holes of the hopper, and then securing it using the screws provided (screws TC+4.8x13).

- Similarly fasten the panel (E) using the screws provided (screws TC+4.8x13).

- Then mount the panel (D) by lining up the lower rectangular holes on the panel folds (E) and fastening them using the screws provided (screws TC+4.8x13).

- The panels (D) and (E) can be mounted either to the right or to the left of the pellet chute (B1); if mounted on the right the additional hopper will have to be mounted to the right of the boiler. .

- Fix the panel (G) by firstly inserting the holes on the bottom on the mounting feet then securing them with the screws provided (screws TC+4.8x13).

- Next mount the panel (F) by inserting the bottom folds on the holes in the panel (G).

Caution: it is mandatory to earth the heater / boiler. If this instruction is not observed serious damage, which is not covered by warranty, will result to the body of the heater / boiler. Have an electrician check the earthing. There must be no electric potential (volts) between the earth of the generator and the actual earth of the plant.

CAUTION : The water temperature in the boiler tubes in this case is not adjustable and depends on the systems's delivery temperature, that is the boiler temperature setting. The boiler tubes can be installed on the water return circuit. Moreover, the Manufacturer recommends installing a water softener in the domestic hot water system in order to prevent the formation of limescale deposits in the boiler tubes which could compromise their functionality.
