Installation Instructions for Built-In

The following instructions are intended for the installer so that the installation and maintenance procedures may be followed in the most professional and expert manner possible.
Positioning
This appliance may only be installed and operated in permanently ventilated rooms in compliance with provisions laid down by current regulations and standards. The following
the requirement must be observed:
A）The room must be fitted with a ventilation system that vents smoke and gases from combustion to the outside. This is must be done by means of a hood or electric ventilator that turns on automatically each time the hood is operated.

B）The room must also allow for the influx of the air needed for proper combustion. The flow of air for combustion purposes must not be less than 2 m 3 /h per kW of installed capacity. The supply of said air can be affected by means of direct influx from the outside through a duct with an inner cross- section of at least 100 cm 2 which must not be able to be accidentally blocked. Those appliances which are not fitted with a safety device to prevent the flame from accidentally going out must have a ventilation opening twice the size otherwise required, i.e.a minimum of 200 cm 2 (Fig. A). Otherwise, the room can be vented indirectly through adjacent rooms fitted with ventilation ducts to the outside as described above, as long as the adjacent rooms are not shared areas, bedrooms, or present the risk of fire (Fig. B).

C）Intensive and prolonged use of the appliance may necessitate supplemental ventilation, e.g. opening a window or increasing the power of the air intake system (if present)

D) Liquefied petroleum gases are heavier than air and as a result, settle downwards. Rooms in which LPG tanks are installed must be fitted with ventilation openings to the outside in order to allow the gas to escape in the event of a leak. Therefore, LPG tanks, whether empty or partially full, must not be installed or stored in rooms or spaces below ground level (cellars, etc.). It is also a good idea to keep only the tank currently being used in the room, making sure that it is not near sources of heat (ovens, fireplaces, stoves, etc.) that could raise the internal temperature of the tank above 50℃.
Installation of Built-In cooktops
The appliance can be installed next to furniture units that are no taller than the top of the cooker hob. The wall in direct contact with the back panel of the cooker must be made of non-flammable material. During operation, the back panel of the cooker could reach a temperature of 50° C above room temperature. For proper installation of the cooker, the following precautions must be taken: If the cabinet (s) located next to the cooktop is higher than the cooktop itself, the cabinet (s) must be installed at least 600 mm from the edge cooktop;
Hoods must be installed in the accordance with the instructions contained in the installation manual for the hoods themselves, and no less than 650 mm from the cooktop.
The cabinets installed next to the hood must be located at a height of at least 420 mm from the top, (as shown in Fig. C)

Should be cooktop be installed directly under a cupboard, later should be at least 720 mm (millimeters) from the top, as shown in Fig. C.
The dimensions of the cutout for the appliance must be those indicated in figure D. Clamps are provided to fasten the cooktop to counters measuring from 20 to 60 mm in thickness. To fasten the cooktop securely, it is recommended that all the clamps be used.

The hob can also be installed above built-in ovens provided with cooling ventilation.
In the event the cooktop is installed above a built-in oven, a wood panel must be inserted as insulation. This panel must be placed at about 50 mm from the bottom of the cooktop itself.
Important: When installing the cooktop above a built-in oven, the oven should be placed on two wooden strips; in the case of a joining cabinet surface, remember to leave a space of at least 45 x 560 mm at the back.

Installation of Built-In Cooktops on a CYLINDER COMPARTMENT
In the event the cooktop is installed above the cylinder compartment, a wood panel must be inserted as insulation. This panel must be placed at about 50 mm from the bottom of the cooktop itself.
The opening of this compartment has to permit the easy introduction and removal of the cylinder. The dimension of the opening and the inside of the compartment shall be at least large enough to accommodate the cylinders (with regulator fitted) which are the most commonly used in the country. The total area of the opening in the upper part shall be at least 1/100 of the floor area of the compartment. The total area of the openings of the base shall be at least 1/50 of the floor area of the compartment. The cylinder support:
Shall have sufficient mechanical strength.
