INTRODUCTION

Dear customer, Thank you for purchasing this MCZ appliance. We are

convinced that, as you operate it, you will appreciate the high quality of this appliance, which is the result of painstaking design and thorough testing. Our aim is to combine technology with simple use and, first and foremost, safety.

Products built with OYSTER technology, where appropriately installed, due to their fully watertight structure, do not draw on the oxygen inside the room. Instead, they draw air from the outside environment and can therefore be fitted in all well-insulated homes and in passive houses. This technology eliminates all risk of smoke being released into the room and ventilation grilles are no longer required. Consequently, there will be no more flows of cold air into the room, making it less comfortable and compromising the overall efficiency of the system.

In the case of forced ventilation or rooms that may be in a negative vacuum compared to the outside, a sealed stove can be installed.

To allow optimal operation of the stove and to benefit fully from the heat and sense of wellbeing distributed throughout your home, we advise you to read this manual carefully before starting it up for the first time; in the event of faults or if in doubt, please contact your retailer, who will provide all the necessary assistance.

2. INSTALLATION RECOMMENDATIONS IN COMPLIANCE WITH UNI

10683

2.1. THE OPERATING ENVIRONMENT

For the correct functioning and an even distribution of heat, the stove should be positioned where the air required for combustion is accessible, in accordance with the installation instructions and the applicable standards in force in the country of installation.

The volume of the room should be no less than 60 m

The air should enter through permanent apertures made in the walls (near the stove) onto the outside with a minimum cross-section of 150

(in the case of non-Oyster installation).

cm These apertures (air inlets) must be made in such a way as not to

obstruct them in any way. Air may also be taken from adjoining rooms to the one to be ventilated,

provided they are equipped with an external air inlet and that they are not used as a bedroom or bathroom or where there is no fire hazard, such as: garages, timber storerooms, warehouses of flammable materials, observing under all circumstances the provisions of all the applicable standards in force.

 If the floor is wood, lay the floor guard down, in

compliance with the applicable standards in force in the country of installation.

 If the walls are not flammable, position the

stove with a minimum rear clearance of at least 10 cm.

 Extreme proximity between the stove and the

wall could cause overheating and damage the plaster (yellowing, cracking, etc.)

 Stove installation and assembly must be

performed by qualified staff.

 The stove must be connected to a flue pipe or a

vertical duct that can discharge the smoke at the highest point of the home.

 The stove must be connected to a flue pipe or

internal or external vertical duct, in accordance with the applicable standards in force.

 The smoke does however result from combustion

of wood essences, and may therefore soil walls if released in contact with or close to the latter.

 Before positioning the stove, drill the hole for

the external air inlet (not in the case of installation with Oyster technology).

2.2. POSITIONING

In the case of concurrent installation with other heating appliances, provide the appropriate air inlets for each one (according to the instructions for each appliance).

Installing the stove in a bedroom or bathroom is not permitted, nor in any room where another heating appliance is installed without an independent air inflow.

It is forbidden to position the stove in rooms with an explosive atmosphere. The floor of the room where the stove is installed must be suitably sized to withstand its weight.

2.2.1. Safe distances

KASAI Non-flammable

A=15cm

* Leave an appropriate distance from the walls in any case in order to allow easier appliance maintenance.

If particularly delicate objects are present, such as furniture, curtains or sofas, increase the stove clearances substantially.

If the stove is positioned on a flammable floor, we recommend you ensure it is suitably insulated.

Heat-sensitive or flammable objects and parts cannot be stored near the stove; keep such objects or parts at a minimum front clearance of 100 cm from the outermost point of the appliance.

2.3. CONNECTING THE COMBUSTION AIR INLET

PIPE

The combustion air outlet does not necessarily have to be connected to the outside; only if you wish to use Oyster technology do you need to connect the combustion air inlet to the outside of the home.

Always use pipes and unions with appropriate seals that guarantee air- and watertightness.

Products built with Oyster technology, due to their fully watertight structure, do not draw on the oxygen inside the room. Instead, they draw air from the outside environment and can therefore be fitted in all well-insulated homes and in passive houses.

In order to satisfy these requirements, the 80 mm diameter connection

pipe for the combustion air inlet must be connected to the outside of

the building.

The air inlet should also:

 be designed with a grille, insect-proof metal mesh or suitable

protection, provided it does not reduce the minimum crosssection.

 be positioned in such a way as to not be obstructed  the maximum length permitted for ducting is 6 m, with two 90°

elbows

The stove must be connected to the external air inlet using pipes and unions which guarantee watertightness to comply with the requirements of the sealed stove (OYSTER technology).

2.4. EXTERNAL AIR INLET

It is necessary for the room in which the stove is installed to provide at least as much air as is required for regular combustion (not in the case of installation with Oyster technology). This can be achieved through permanent apertures made in the walls of the room to be ventilated onto the outside or rooms aired in accordance with UNI 10683 REV.

To this end, drill a through hole in the external wall near the stove with a minimum free cross-section of 150 cm². (15 cm diameter or 10x15 cm rectangular hole), protected by a grille on the inside and on the outside.

The air inlet should also:

 communicate directly with the installation setting  be designed with a grille, insect-proof metal mesh or suitable

protection, provided it does not reduce the minimum crosssection.

 be positioned in such a way as to not be obstructed
