the profession.

Installation must only be carried out by a qualifed technician who works on behalf of companies suitable to assume the

entire responsibility of the system as a whole. HOSSEVEN A.S. declines any responsibility for the product that has

been modifed without written authorisation as well as for the use of non-original spare parts.

It is OBLIGATORY to respect the National and European rules, local regulations concerning building matter and also

fireproof rules.

NO MODIFICATIONS CAN BE CARRIED OUT TO THE APPLIANCE. HOSSEVEN A.S.. cannot be held

responsible for lack of respect for such precautions.

INSTALLATION REGULATIONS

Installation of the Product and auxiliary equipment in relation to the heating system must comply with all current Standards and

Regulations and to those envisioned by the law.

The installation and the relating to the connections of the system, the commissioning and the check of the correct functioning must

be carried out in compliance with the regulations in force by authorised professional personnel with the requisites required by the

law, being national, regional, provincial or town council present in the country within which the appliance is installed, besides these

present instructions.

Installation must be carried out by authorised personnel who must provide the buyer with a system declaration of conformity and will

assume full responsibility for fnal installation and as a consequence the correct functioning of the installed product.

The Product, assembled and ready for the installation, must be connected with a junction to the existing ﬂue of the house. The

junction must be possibly short, straight, horizontal or positioned a little uphill. The connections must be tight.

Before installing the appliance, carry out the following checks:

• UPPER smoke output - REAR - LATERAL

• verify if your structure can support the weight of the appliance. In case of insuffcient carrying capacity it is necessary to

adopt appropriate measures, HOSSEVEN A.S. responsibility is limited to the supply of the appliance (See chapter TECHNICAL

DESCRIPTION).

• Make sure that the ﬂoor can support the weight of the appliance (for ex. distributing weight plate), and if it is made of ﬂammable

material, provide suitable insulation (DIMENSIONS ACCORDING TO REGIONAL REGULATIONS).

• Make sure that there is adequate ventilation in the room where the appliance is to be installed, with particular attention to

windows and doors with tight closing (seal ropes).

• Do not install the appliance in rooms containing collective ventilation ducts, hoods with or without extractor, type B gas

appliances, heat pumps, or other appliances that, operating at the same time, can put the room in depression .

• Make sure that the ﬂue and the pipes to which the appliance will be connected are suitable for its operation. It is NOT allowed the

connection of various appliances to the same chimney.

• The installation must be appropriate and has to allow the cleaning and maintenance of the product and the ﬂue.

Your regular local chimney sweep must be informed about the installation of the appliance so that he can check the correct connection

to the chimney

FIRE SAFETY

When installing the product, the following safety measures must be observed:

a) In order to ensure suffcient thermal insulation, respect the minimum safety distance from objects or furnishing components

ﬂammable and sensitive to heat (furniture, wood sheathings, fabrics. etc.) and from materials with ﬂammable structure (see

Picture). All the minimum safety distances are shown on the product data plate and lower values must not be used.

b) In front of the furnace door, in the radiation area there must be no ﬂammable or heat-sensitive objects or material at a distance of

less than 100 cm. This distance can be reduced to 40 cm where a rear-ventilated, heat-resistant protection device is installed in

front of the whole component to protect.

c) If the product is installed on a non totally refractory ﬂoor, one must foresee a fireproof background. The ﬂoors made of inﬂammable

material, such as moquette, parquet or cork etc., must be covered by a layer of no-inﬂammable material, for instance ceramic,

stone, glass or steel etc. (size according to regional law). The base must extend at least 50 cm at the front and at least 30 cm at

the sides, in addition to the opening of the loading door (see Picture).

d) No ﬂammable components (e.g. wall units) must be present above the product.

The Product must always operate exclusively with the ash tray inserted. The solid combustion residues (ash) must be collected in

a sealed, fire resistant container. The Product must never be on in the presence of gaseous emissions or vapours (for example glue

for linoleum, petrol etc.). Never deposit ﬂammable materials near the Product.

When using the wrong fuel or one which is too damp, due to deposits present in the ﬂue, a ﬂue fire is possible.

HOSSEVEN A.S. declines all responsibility for damage to things and/or persons caused by the system. In

addition, it is not responsible for any product modifed without authorisation and even less for the use of

non original spare parts.

During combustion, thermal energy is released which leads to considerable heating of the surfaces, doors,

handles, controls, glass parts, the ﬂue gas pipe and possibly the front part of the appliance. Avoid contact

with these elements unless using suitable protective clothing or accessories (heat resistant gloves, control

devices). Ensure children are aware of these dangers and keep them away from the furnace when it is on.

IN A EMERGENCY

If there is a fire in the ﬂue connection :

a) Close the loading door and the ash tray door

b) Close the comburent air registers

c) Use carbon dioxide ( CO₂powder ) extinguishers to put out the fire

d) Request the immediate intervention of the Fire Brigade

With thermal insulation in accordance with the regulations regarding energy saving, the heated volume is greater. With temporary

heating, in the event of interruptions which last more than 8 hours, the heating capacity is reduced by about 25%.

The declared technical data have been achieved by burning beech wood class “A1” according to the requirement UNI EN ISO 17225-

5 and wood moisture content less than 20%. By burning a different kind of wood the effciency of the product itself could change and

some specifc adjustments on the appliance could be needed.

TECHNICAL DESCRIPTION

The cookers of Hosseven A.S. are suitable to cook on the grill and on the oven and to heat living spaces for some periods or to support

an insuffcient centralized heating system. They are ideal for holiday apartments and weekend houses or as an auxiliary heating system

during the whole year. As fuel, wood logs is used. The appliance works as an intermittent operating appliance.

The hearth is totally sheathed with single cast iron sheets and it is endowed with a pre-adjusted tertiary air for a better combustion.

Inside there is a thick ﬂat grate. The hearth is equipped with a panoramic door with ceramic glass (resistant up to 700 °C) and outside

tempered. This allows a wonderful view on the burning ﬂames. Furthermore, it is thus avoided the output of sparks and smoke.

The heating of the environment is made by irradiation: through the panoramic glass and the external hot surfaces of the stove,

the heat is radiated into the environment.

The cooker is equipped with controls of primary and secondary air by which it is adjusted the combustion air.

CENTRAL HEATING SYSTEM

Adjust the draught thermostat (Picture-08 no.14) desired temparature ( for example 50 °C..60 °C..), push the chimmny flap (Picture.10

no.19) to close. Secondary air (Picture-06/09 no.5) must be open. Keep the draught thermostat primary air inlet open, keep the other

air inlets closed position during central heating period.

Fire prevention safety distances Chapter FIRE SAFETY

DO NOT PUT OUT THE FIRE WITH WATER.

When the ﬂue stops burning, have it checked by a specialist to identify any cracks or permeable points.

SMOKES control (see Picture)

(Conversion of the cooker function to the cooker, bake oven and heating function).

The smokes control, in the style of a chromed pull push lever, can be found on the top right corner of the front side of the cooker,

between the protection bar and the oven door. This control has two settings:

HOB COOKING: when the bar is pushed to the back of the cooker, the combustion gases ﬂow around the oven and directly into

the ﬂue and up to the chimney. OVEN COOKING: when the control bar is pulled out, the combustion gases ﬂow around the oven,

heating it.

To ignite the ﬂame follow the instructions below (see Cap. IGNITION) :

• Bring the ﬂue gas control to the cooker position (any butterﬂy valve placed on the ﬂue gas exhaust pipe must also be opened).

• Open the primary and secondary air control.

• After having started the fire with small pieces of wood and waited until it is well lit.

• Bring the ﬂue gas control to the oven position.

• Close any butterﬂy valve placed on the ﬂue gas exhaust pipe must also be opened.

The control regulation during the ignition phase is the following :

SMOKE CONTROL FOR COOKING

Hob Cooking (Hot plate use)

Keep the draught thermostat adjusted position , pull the chimmny flap (Picture-10 no.19) to make full open position.

Oven Cooking

Push the chimmny flap to close position. If you like to cook top side of the meat ,you can make the chimmny flap (Picture-10 no.19)

as open position (for this pull it). You can follow the oven temparature a termometer installed on the oven glass door.

Slow Burning

Close primer and sconder air inlets and adjust the draught thermostat for minumum temparature value.( 30°C)

Clean the ash tray from time to time not to obstract to air inlet.

FLUE

Essential requirements for correct appliance operation:

• the internal section must preferably be circular;

• the appliance must be thermally insulated and impermeable and built with suitable materials which are resistant to

heat, combustion products and any condensation;

• there must be no narrowing and vertical passages with deviations must not be greater than 45°;

• if already used, it must be clean;

• the technical data from the instruction manual must be respected;

If the ﬂues are of a square or rectangular section, the internal edges must be rounded with a radius of not less than 20 mm.

For the rectangular section, the maximum ratio between the sides must be ≤ 1.5.

A section which is too small causes a reduction in draught. A minimum height of 4 m is advisable.

The following materials are FORBIDDEN and compromise the good operation of the appliance: asbestos cement, galvanised steel,

rough and porous internal surfaces. Picture 1 shows some example solutions.

The minimum section must be 4 dm2 (for example 20x20 cm) for appliances whose pipe dimensions are less than 200 mm,

or 6.25 dm2 (for example 25x25 cm) for appliances with a diameter of more than 200 mm.

The draught created by your ﬂue must be suffcient but not excessive.

A section of the ﬂue which is too large can present a volume which is too large to heat and therefore cause operating diffculties

for the appliance; to avoid this, it is necessary to intubate the appliance for its entire height. A section which is too small causes a

reduction in draught.

CHIMNEY POT

The ﬂue draught depends on the suitability of the chimney pot.

It is therefore essential that, if built in a handcrafted way, the exit section is more than twice the internal section of the ﬂue

(Picture 2) .

As it must always go past the ridge of the roof, the chimney pot must ensure exhaust even in the presence of wind (Picture 3).

The chimney pot must meet the following requirements:

• Have an internal section equivalent to that of the chimney.

• Have a useful exit section of double the internal section of the ﬂue.

• Be built so as to prevent rain, snow or any foreign body entering the ﬂue.

• Be easy to inspect, for any maintenance and cleaning operations.

The chimney pressure (DRAUGHT) must be at least 12 Pa Pascal (=1.2 mm of water column). The measurement must always be

carried out when the appliance is hot (nominal calorifc power). When the pressure exceeds 17 Pascal, it is necessary to reduce

it through the installation of an additional draught regulator (false air valve) on the exhaust pipe or in the chimney, according to the

regulations in force.

For correct appliance operation, it is essential that suffcient air for combustion is introduced into the place of installation.

CONNECTING A FIREPLACE OR OPEN HEARTH TO THE FLUE

The ﬂue gas channel is the stretch of piping which connects the product to the ﬂue. In the connection, these simple but extremely

important principles must be respected:

• under no circumstances use a ﬂue gas channel with a diameter less than that of the exhaust clamp with which the product is

equipped;

• each meter of the horizontal stretch of the ﬂue gas channel causes a slight loss of head which must be compensated if necessary by

elevating the ﬂue;

• the horizontal stretch must never exceed 2 meters.

• each bend of the ﬂue gas channel slightly reduces the ﬂue draught which must be compensated if necessary by elevating it suitably;

• Regulation requires that under no circumstances must there be more than 2 bends or variations in direction including the intake into

the ﬂue. (Picture-17-18)

ATTENTION: as far as concern the realisation of the ﬂue connection and ﬂammable materials please follow the

requirements provided by related standard. The ﬂue must be at a suitably distance from ﬂammable or

combustible material using suitable insulation or an air space. It is FORBIDDEN to pass system piping or air ducts

inside the ﬂue. It is also forbidden to create moveable or fxed openings on the ﬂue itself, for the connection of

further different appliances (See chapter CONNECTING A FIREPLACE OR OPEN HEARTH TO THE FLUE)

ATTENTION: as far as concern the realisation of the ﬂue connection and ﬂammable materials please follow

the requirements provided by related standard. The ﬂue must be properly spaced from any ﬂammable

materials or fuels through a proper insulation or an air cavity. Minimum distance safety 25 cm.

AIR FLOW IN THE PLACE OF INSTALLATION DURING COMBUSTION

As the product draw their combustion air from the place of installation, it is MANDATORY that in the place itself, a suffcient quantity

of air is introduced. If windows and doors are airtight (e.g. built according to energy saving criteria), it is possible that the fresh air

intake is no longer guaranteed and this jeopardises the draught of the appliance and your health and safety. It is therefore necessary

to guarantee a supply of fresh air through an external air inlet placed near the appliance or by placing piping for combustion air

which leads outside or to a nearby airy place, with the exception of the boiler room or garage (FORBIDDEN).

The intake of air for combustion in the place of installation must not be obstructed during operation of the product. It is absolutely

essential that in environments in which products are operated with a natural chimney draught, as much air as is necessary for

combustion is introduced, i.e. up to 20 (<11kW) m³/hour. The natural recirculation of air must be guaranteed by some fixed openings

to the outside. Their size is established by regulations regarding the subject. Ask for information from a chimneys weep. The

openings must be protected with grills and must never be blocked up. An extractor hood (suction) installed in the same room or in a

neighbouring one causes a depression in the environment. This causes the leakage of burnt gas (dense smoke, smell); it is therefore

necessary to ensure a greater ﬂow of fresh air.

ALLOWED / NOT ALLOWED FUELS

Allowed fuels are logs. Use exclusively dry logs (max. content of water 20%). Maximum 3 logs should be loaded. The pieces of wood

should have a length of ca. 20-30 cm and a maximum circumference of 30-35 cm.

Compressed not worked-out wood briquettes must be used carefully to avoid overheating that may damage the device, since

these have a very high calorifc value.

The wood used as fuel must have a humidity content lower than the 20% and must be stored in a dry place. Humid wood tends to

burn less easily, since it is necessary a greater quantity of energy to let the existing water evaporate. Moreover, humid content

involves the disadvantage that, when temperature decreases, the water condensates earlier in the hearth and therefore in the stack

causing a remarkable deposit of soot with following possible risk of fire of the same.

Fresh wood contains about 60% of H₂O, therefore it is not suitable to be burnt.

It is necessary to place this wood in a dry and ventilated place (for example under a roof) for at least two years before using it.

Besides others, it is not possible to burn: carbon, cuttings, waste of bark and panels, humid wood or wood treated with paints,

plastic materials; in this case, the warranty on the device becomes void.

Paper, cardboard and wax emmited paper must be used only to light the fire.

The combustion of waste is FORBIDDEN and would even damage the appliance and the ﬂue, causing health damages and claims by

the neighborhood owing to the bad smell.

The wood is not a fuel which allows a continuous operation of the appliance, as consequence the heating all over the night is not

possible.

The declared technical data have been achieved by burning beech wood class “A1” according to the requirement EN ISO 17225-5 and

wood moisture content less than 20%. By burning a different kind of wood the effciency of the product itself could change and some

specific adjustments on the appliance could be needed

The depression of an extractor hood can, in the worst case scenario, transform the ﬂue of the product into

an external air inlet, re sucking the ﬂue gases into the environment with very serious consequences for

persons.

ATTENTION : the continuous and protracted use of aromatic wood (eucalyptus, myrtle etc.) quickly damages

the cast iron parts (cleavage) of the product

LIGHTING

To perform a correct first lighting of the products treated with paints for high temperature, it is necessary to know the following

information:

• the construction materials of the involved products are not homogeneous, in fact there are simultaneously parts in cast iron, steel,

refractory material and majolica;

• the temperature to which the body of the product is subject is not homogeneous: from area to area, variable temperatures within

the range of 300°C -500°C are detected;

• during its life, the product is subject to alternated lighting and extinguishing cycles in the same day, as well as to cycles of intense

use or of absolute standstill when season changes;

• the new appliance, before being considered seasoned has to be subject to many start cycles to allow all materials and paints to

complete the various elastic stresses;

• in detail, initially it is possible to remark the emission of smells typical of metals subject to great thermal stress, as well as of wet

paint. This paint, although during the manufacture it is backed at 250 °C for some hours, must exceed many times and for a given

period of time the temperature of 350 °C before becoming completely embedded in the metallic surfaces.

ENgLIsH

Therefore, it is extremely relevant to take these easy steps during the lighting:

1. Make sure that a strong air change is assured in the room where the appliance is installed.

2. During the first starts, do not load excessively the combustion chamber (about half the quantity indicated in the instructions

manual) and keep the product continuously ON for at least 6-10 hours with the registers less open than the value indicated in the

instructions manual.

3. Repeat this operation for at least 4-5 or more times, according to your possibilities.

4. Then load more and more fuel (following in any case the provisions contained in the installation booklet concerning maximum

load) and, if possible, keep the lighting periods long avoiding, at least in this initial phase, short ON/OFF cycles.

5. During the first starts, no object should be leaned on the appliance and in detail on enameled surfaces. Enameled

surfaces must not be touched during heating.

6. Once the «break-in» has been completed, it is possible to use the product as the motor of a car, avoiding abrupt heating with

excessive loads.

To light the fire, it is suggested to use small wood pieces together with paper or other traded lighting means.

The openings for air (primary and secondary) must be opened together (you must open the eventual Ignition control, and butterﬂy

valve placed on the pipe of smokes exhaust). When the wood starts burning, you may load other fuels and adjust the air for

combustion according to the instructions on paragraph TECHNICAL DESCRIPTION.

Please always be present during this phase.

LOW EMISSION fire lighting

Smokeless combustion is a way of lighting a fire able to signifcantly reduce the emission of harmful substances. The wood burns

gradually from the top downwards, so combustion is slower and more controlled. Burnt gases pass through the high temperatures of

the ﬂame and therefore burn almost completely.

Place the logs in the hearth a certain distance apart. Arrange the largest at the bottom and the smallest at the top, or vertically in the

case of tall narrow combustion chambers. Place the fire starter module on top of the pile, arranging the first logs in the module at

right angles to the pile of wood.

Fire STARTER MODULE. This fire starter module replaces a paper or cardboard starter. Prepare four logs, 20 cm long with a cross

section of 3 cm by 3 cm. Cross the four logs and place them on top of the pile of wood at right angles, with the fire lighter (wax

impregnated wood fbre for example) in the middle. The fire can be lit with a match.

If you want, you can use thinner pieces of wood. In this case, you will need a larger quantity.

Keep the ﬂue gas exhaust valve and combustion air regulator open.

After lighting the fire, leave the combustion air regulator open in the position shown in according to the instructions on paragraph

TECHNICAL DESCRIPTION

WARNING: After the first ignition you can smell bad odours (owing to the drying of the glue used in the

garnitures or of the paint) which disappear after a brief using of the appliance. It must be ensured, in any case,

a good ventilation of the environment. Upon the first ignition we suggest loading a reduced quantity of fuel

and slightly increasing the calorific value of the equipment. It is FORBIDDEN to use any liquid substance as for

ex. alcohol, gasoline, oil and similar. Never switch on the device when there are combustible gases in the

room.

Never overload the appliance (see cap. TECHNICAL DESCRIPTION / hourly consumption). Too much fuel

and too much air for combustion can cause overheating and therefore damage the appliance. The

warranty does not cover the damages due to overheating of the equipment.

IMPORTANT:

• do not add further wood between one complete load and the next;

• do not suffocate the fire by closing the air intakes;

• regular cleaning by a chimney sweep reduces fne particle emissions.

NORMAL OPERATION

After having positioned the registers correctly, insert the indicated hourly wood load avoiding overloads that cause anomalous

stresses and deformations (according to the instructions on paragraph TECHNICAL DESCRIPTION). You should always use the product

with the door closed in order to avoid damages due to overheating (forge effect). The inobservance of this rule makes the

warranty expire.

For safety reasons the door of the appliances with constructive system 1, must be opened only for the loading of the fuel or for

removing the ashes, while during the operation and the rest, the door of the hearth must remain closed. The appliances with

constructive system 2 must be connected to their own ﬂue. The operating with open door is allowed under supervision.

With the controls positioned on the front of the appliance it is possible to adjust the heat emission of the hearth. They have to be

opened according to the calorifc need. The best combustion (with minimum emissions) is reached when, by loading the wood, most

part of the air for combustion ﬂows through the secondary air register.

Never overload the appliance. Too much fuel and too much air for the combustion may cause overheating and then damage the

stove. You should always use the appliance with the door closed in order to avoid damages due to overheating (forge effect). The

inobservance of this rule makes the warranty expire. The adjustment of the registers necessary to reach the rated calorifc yield with

a depression at the stack of 12 Pa 1,2mm of column of water) is the following one: see chapter TECHNICAL DESCRIPTION. The

appliance works as an intermittent operating appliance. Besides the adjustment of the air for the combustion, the intensity of the

combustion and consequently the thermal performance of the device is inﬂuenced by the stack. A good draught of the stack requires

a stricter adjustment of air for combustion, while a poor draught requires a more precise adjustment of air for combustion.

ENgLIsH

To verify the good combustion, check whether the smoke coming out from the stack is transparent. If it is white, it means that the

device is not properly adjusted or the wood is too wet; if instead the smoke is gray or black, it signals that the combustion is not

complete (it is necessary a greater quantity of secondary air).

USE OF THE OVEN

Thanks to the air ﬂow for the combustion, the temperature of the oven may become remarkably affected. A suffcient ﬂue of the

chimney and of the channels, well cleaned for the ﬂow of burning smokes around the oven are fundamental for a good cooking

result.

Thick cakes and big roasts must be introduced in the lowest level. Flat cakes and biscuits must reach the medium level. The upper

level may be used to heat or grill.

The oven pan and the chrome plated oven grille may be located on different plans (see chapter Technical Description - ACCESSORIES).

When cooking food with high humidity, cakes with fruit or fruit itself, water of condensation will be produced. During the cooking

process some water vapour in the form of drops of condensed water can deposit onto the top and the side of the door. It is a physical

phenomenon.

By opening the door brieﬂy and carefully (1 or 2 times, or even often in case of longer cooking times) you can let out the steam from

the cooking compartment and reduce condensation signifcantly.

OPERATION IN TRANSITION PERIODS

During transition periods when the external temperatures are higher, if there is a sudden increase of temperature it can happen that

the combustion gases inside the ﬂue cannot be completely sucked up.

The exhaust gases do not come out completely (intense smell of gas). In this case, shake the grating more frequently and increase the

air for the combustion. Then, load a reduced quantity of fuel in order to permit a rapid burning (growing up of the ﬂames) and the

stabilization of the draught. Then, check that all openings for the cleaning and the connections to the stack are air-tigh. In case of

doubt, DO NOT operate the product.

MAINTENANCE AND CARE

Check the external air intake, by cleaning it, at least once a year. The stack must be regularly swept by the chimney sweeper. Let your

chimney sweeper in charge of your area check the regular installation of the device, the connection to the stack and the aeration.

IMPORTANT: For safety reasons the door of the hearth can be opened only for the loading of the fuel. The

hearth door must always remain closed during operation or rest

WARNING: When fuel is added onto the embers in the absence of a ﬂame, a considerable amount of fumes may

develop. Should this happen, an explosive mixture of gas and air may form, and in extreme cases an explosion

may occur. For safety reasons it is advisable to perform a new lighting procedure with the use of small strips.
