Cola s.r.l. declines any liability for problems, breakage or accidents caused by failure to follow or apply the instructions contained in this manual.ENEA – ENEA FORNO

ENEA – ENEA FORNO model stoves burn solid fuel and are suitable for home heating. Both stoves have the same combustion chamber, with a nominal output of 7.5 kW, and ensure a maximum heatable volume of approx. 214 m3 considering an energy requirement coefficient equal to 35 W/m3; this can vary depending on the insulation, type of building and climatic zone. The stove is tested with wood fuel complying with the requirements of Standard EN 13240 and is classified as an intermittent combustion domestic appliance. The firebox is entirely in refractory tiles, which allows clean combustion with low emissions, and is closed frontally by a cast iron door with ceramic glass for aesthetic purposes and control. The layouts of the stoves are given in the enclosures, i.e. 7.1 ENEA model and 7.2 ENEA FORNO model; the following sections refer to the points in the above-mentioned layouts.

The fire door is opened by pulling the handle outwards; use the protective glove supplied with the stove when the handle is hot. Thin slots around the top and bottom edges of the fire door glass provide an airwash to keep the glass clean.

The ash door is integrated with the fire door (A) and is opened by pulling the handle outwards, to access a compartment with the removable ash pan inside.

1.3.3 Primary air flow control (B)

The rotary control on the ash door regulates the primary air flow into the lower part of the stove through the ash pan and grate. The primary air is necessary for the combustion process, therefore make sure to empty the ash pan regularly so that the ash cannot obstruct the combustion air inlet. When the arrow is in position ‘ 0 ‘ the air inlet is closed; when the arrow is in position 3 the air inlet is fully open ( figure 6.2). Higher air settings may cause overheating and consequent damage to the stove.

1.3.4 Secondary air (C)

The stove's secondary air inlet located on the back is for burning unburnt gases produced by the combustion process.

(if present ) The oven is heated by the flow of combustion gases around it and its temperature can be read on the thermometer on the door glass (E). A sufficient draught and clean fume ducts are essential for optimum efficiency. The oven has two racks. When putting pans into the oven, allow for possible rising of the product inside and ensure a space of at least 20 mm between the pan and the sides of the oven.

Permissible fuels are natural-type pieces of dry and resin-free wood (beech, oak and birch), 20-25 cm long. The wood should be seasoned at least two years; the maximum recommended moisture content is 20%, in order to ensure combustion without smoke and soot. Do not use: - coal dust; - thin strips of wood (only permitted as kindling); - bark and shavings; - waste in general; - treated cardboard and paper; - wood treated with protective substances. The burning of waste is prohibited according to European and national laws. - The burnt gases produced by the combustion of unsuitable materials can cause damage to the stove and flues, and compromise your health. - The use of any fuel that does not comply with the above indications will void the warranty.

For the dealer: To request any replacement parts, contact the Cola s.r.l. assistance service and/or send a fax clearly specifying the following: - stove model; - serial number; - date of purchase; - list of replacement parts; - details of faults detected. - Operations on components must be carried out by authorised and/or qualified personnel. - Only use Cola original replacement parts.

1.9 Stove decommissioning

For its disposal, the stove must be sealed inside strong packing; contact the competent local authorities for information on how to proceed according to the current local regulations.

2.1 Packing, handling, shipment and transport

The stove can be lifted using a lift truck, inserting the forks (of suitable length) in the special spaces in the wooden packing. Make sure the equipment used for lifting and transport can take the weight of the stove, specified on the data plate and in this manual. Avoid taking the load in areas where it could be a danger if dropped. Set the stove down on the floor carefully without jolting and position it in the required place, after making sure the floor can take the weight of the stove; otherwise consult a specialised technician.

2.2 Instructions for safe installation

Proper operation of a heating and cook stove depends above all on its installation, which must be carried out by a competent person, in compliance with the current safety regulations. The stove must only be operated with the ash pan inserted, and disposal of the products of combustion must take place daily, avoiding excessive deposits that can affect its safe operation. The sides and back must be 20 cm ( fig.5 –ref A_B) from flammable materials. No flammable material or objects must be placed less than 100 cm (fig.5 –ref.C) in front of the fire door. If the floor is made of combustible material (wood, carpet, etc.), a protection base in 2-3 mm thick sheet metal or other non- flammable material of a certain thickness must be provided; in this case the base should protrude at least 50 cm from the front and 20 cm from the sides of the stove.

- An incorrectly installed stove can be the cause of serious accidents (flue, insulation materials, etc., catching fire). - Do not store flammable material near the stove. - Installation must be carried out, ensuring access for maintenance and cleaning the stove and flue.

2.3 Connection to the flue

The ENEA – ENEA FORNO stove must be connected to the flue via the collar on the hotplate, using flue pipes that are readily available on the market. Connection to the chimney must be made using strong and sturdy pipes of recommended minimum thickness 1.2-2 mm. The flue pipe must possibly be straight, to avoid pressure losses, and towards the flue. The ends of the flue pipe must be tight. To ensure regular operation, the flue draught with stove operating must be between 10 and 14 Pa. For maximum stove efficiency, a draught restrictor or damper should be installed in the flue pipe or chimney. Each stove must eliminate the fumes through its own flue; never use the same flue for several units.

2.4 Room ventilation

The air necessary for combustion, i.e. up to 25 m³ every hour, must be ensured in rooms where stoves with natural flue draught are installed. The air exchange must occur with at least one fixed opening to the outside, whose section depends on the current local regulations and in any case must not be less than 100 cm2. Such openings must be protected with grilles and must never be obstructed. If the air is insufficient, even the operation of an extractor hood in the room can negatively affect stove operation.

2.5 Advice on flues and connections

Flues must be made from suitable materials and perfectly insulated, with characteristics that prevent temperature decreases. The inner walls must be perfectly smooth without any narrowing or protrusions along the entire length, so as not to create friction or vortices in the smoke which could cause a considerable reduction in draught. Any doors for cleaning and inspection must be perfectly closed during operation. The flue outlets must be 0.5 m higher than any obstacles located less than 10 m away and must end with chimney caps or cowls having a useful outlet cross section of at least double that of the flue. Figures 1– 2 give the data regarding the distances and positioning of chimney caps in conformity with the provisions of UNI 10683. Before connecting the stove to an existing chimney, in addition to complying with that described above, make sure there are no openings or cracks where air could enter and cause a temperature decrease affecting the draught. Also make sure there are no obstructions caused by foreign bodies or a buildup of soot. The first connection section leaving the stove should be vertical, whereas the flue connection to the chimney (which goes to the chimney cap) must only enter by a few cm, so as not to reduce the cross section of the flue. If the flue is not perpendicular to the chimney it is advisable to make the connection with special steel fittings that allow a maximum slope of 45°. If the walls and ceiling are made of flammable materials, the parts in contact with the flue must be suitably insulated. All connection joints must be carefully sealed, in particular where the connection enters the flue. If there are several heating cook stoves in the same home, each must have its own flue. It is inadvisable to make openings in the flue for connecting other appliances, as this could affect the draught. According to Standard UNI 7429, the chimney cap must meet several requirements; above all, it must have a useful outlet cross section at least double that of the flue. It is also advisable to install an "antiwind" cap that guarantees fume exhaust even in the presence of strong crosswinds (figures 3 – 4

Suitable fire-prevention devices should be arranged for any eventuality. In case of a fire, proceed as follows: - Immediately close the loading door and the ash pan. - Close the combustion air controls. - Extinguish the fire using suitable fire-extinguishers. - Call the fire department immediately. - Do not use jets of waters to extinguish the fire.3

Never leave children unsupervised in the vicinity of the stove; there is a very high risk of burns from the hot surfaces. Also: - never use the stove with the fire door open; - do not store firelighters or other easily combustible materials in the vicinity of the stove; - do not try to move or lift the stove by the handles.

When lighting the stove the first time, bad odours may be created, therefore air the room thoroughly. When lighting the stove the first time, allow it to burn with a low flame for several hours (air control on ash door open 30%) and with very little fuel. The heat can then be increased a little at a time, so that the stove expands slowly and the sealants and putties dry. During the heating and cooling cycles, the combustion chamber in refractory cement undergoes heat stress and expansion, which causes fine cracks to form. Such cracks do not affect stove efficiency or its service life.

3.3 Lighting and adding fuel

To light the stove, it is advisable to use kindling and newspaper, or commercially available firelighters (excluding all inflammable liquids). When lighting the stove, the air control on the fire door must be fully open; after lighting, it is used to regulate stove heat output. Never use petrol, alcohol or other flammable liquids to light the fire.

3.4 Adjusting the combustion air flow

Primary air: the primary air is adjusted using the manual revolving controls located on the ash door, and feeds the fire through the grate. Secondary air: the secondary air enters the stove through the holes in the back. Optimum combustion conditions are obtained when, on loading wood, the air necessary for combustion enters through the grate, whereas the secondary air ensures the completion of combustion in the upper part of the firebox.

3.5 Normal operation

Remove the ash from the grate each time before loading fuel. Put 2-3 pieces of wood on the bed of embers. Given the large capacity of combustion chamber it is advisable not to exaggerate, but to load up to 2-3 pieces of wood at a time. For normal operation set the primary air control to halfway. Overloading does not increase heat output, but will overheat the stove, damaging it.

3.6 Operation with slow combustion

Heat output can be adjusted by reducing the combustion air. To ensure operation for many hours at low heat, the primary air controls must be opened at minimum. With partial feed operation, a patina may form on the glass due to the low temperature in the combustion chamber. In any case, a continuous fire with low heat is not advisable.

3.7 Operation in low season

With outside temperatures above 15°C, the draught may be affected, resulting in a decrease in heat output and with flue gases not being completely exhausted (smell of smoke in the room). In this case it is advisable to clean the ash from the grate and increase the combustion air. Put less fuel on the fire and clean the grate more frequently.

The stove has a 18-litre static oven, covered entirely in stainless steel sheet and provided with 2 racks for holding trays.A thermometer installed on the glass of the enamelled door shows the oven temperature. When the stove is lit for the first time, the oven should only be used after 1-2 hours of operation at 200-250°C with the oven door left ajar to eliminate fumes produced by manufacturing process residuals such as grease, oil and sealants. To reach adequate temperatures is necessary increase the primary air. Clean the oven every time it is used, following the instructions given in the section on cleaning. The oven must only be used for its intended purposes, i.e. cooking foods; any other use is improper and dangerous.ENEA – ENEA FORNO

3.9 Idle period and summer

In summer, it is advisable to clean the combustion chamber, ash pan, fume ducts in the oven, the chimney and flue; also, remove all residuals on the inside and outside of the stove, check all seals and replace them if necessary. The appearance of the hotplate and other cast iron parts can be maintained by applying neutral vaseline. At the end of maintenance operations, close the doors and air controls to prevent dust, etc., from entering. If the stove is not going to be used for a long period, after the above operations and disconnecting from the flue, it is advisable cover it with a protective cloth and store in a safe and protected place.

4 – ROUTINE STOVE CLEANING AND MAINTENANCE

Good maintenance will help keep improve the stove's efficiency and prolong its service life. Daily, before lighting the fire, clean the grate and remove any unburnt wood and ash from the ash pan zone.

The ENEA – ENEA FORNO stove has a removable grate which should be cleared of ash, using the poker supplied, every time before loading fuel. Make sure to empty the ash pan regularly, as accumulated ash under the grate will obstruct the flow of combustion air. The grate will get too hot and may be damaged. To prevent the risk of fire, allow the ashes to cool outdoors in a metal container or in the stove and eliminate them in compliance with the current local regulations.

4.2 Cleaning the glass

The glass can be cleaned using a damp cloth and normal non-abrasive detergents. Remove any encrustations with suitable detergents, before they become dry. The ceramic glass can withstand temperatures of around 750°C: in case of breakage, it is advisable to replace it with another original glass supplied by Cola. Do not clean the glass during stove operation: cleaning must be carried out when the stove is cold.

The stove's cladding must only be cleaned when cold. The ceramic tiles are hand-crafted products and therefore may have minor surface imperfections such as tiny spots or slight colour differences. It is advisable to use a soft dry cloth to clean the ceramic surfaces; the use of detergents could highlight any flaws.

4.4 Cleaning the oven

It is advisable to clean the oven when lukewarm or cold and after each use, to prevent dirt from depositing on the surface. To clean the stainless steel surfaces of the oven, use non-abrasive detergents with a soft cloth, rinsing thoroughly to prevent any residues of detergent from contaminating food and corroding the oven materials. To clean the bottom baffle under and around the oven, remove the oven door “D” and its closing frame.

4.5 Cleaning the flue and baffle

A reduction in heat output is nearly always due to obstruction of the flue. Also, the escaping of burnt gases with odours can be the sign of an obstructed flue. The flue of your stove must be cleaned at regular intervals. The amount of soot and the frequency of cleaning will depend largely on the type of fuel and how the stove is used (i.e. low or high output). Clean the flue pipes, proceeding as follows: - Clean only when the stove is cold; - Close all openings that are not to be cleaned; - Remove the flue pipes and clean them outdoors; - Detach and suck the deposits inside the stove with the wire brush; - All residuals on the grate or in the ash pan must be removed; - Remove the layer of soot under the oven zone using ascraper; Close accurately the openings for the cleaning and also check the seal of the closure cap; in case it is damaged during cleaning the seal must be replaced.ENEA – ENEA FORNO
