Room Ventilation; Combustion Gas Discharge; Connection To Gas - Smeg SY4110 Instructions For Use Manual

4.3 Room ventilation

The appliance may only be installed in a permanently ventilated room as specified by the relevant
regulations. The air flow into the room where the appliance is installed must be sufficient for proper gas
combustion and room ventilation. The air vent, protected by gratings, must be of suitable size (see
relevant regulations) and located so that they cannot be even partially obstructed.
The kitchen must be kept properly ventilated to disperse the heat and humidity produced by cooking
processes: in particular, a window should be opened or the speed of any fans increased after prolonged
use.

4.4 Combustion gas discharge

Combustion gases may be discharged by means of hoods connected to a natural draught chimney or a
fan extraction system. An efficient extraction system requires precise planning by an authorised
specialist and must comply with the distances and positions indicated by the regulations. After
installation, the specialist must issue a certificate of compliance.

4.5 Connection to gas

Installation of the UNI-CIG 7140 compliant rubber hose must be carried out so that the hose length is not
greater than 1.5 metres. Make sure that the hose does not come into contact with moving parts or is
squashed. The inside diameter of the hose must be 8 mm for LIQUID GAS and 13 mm for NATURAL
GAS and TOWN GAS.
Verify that all the following conditions are met:
• the hose is fixed to the hose connection with safety clamps;
• no part of the hose is in contact with the hot walls (max. 50 °C);
• the hose is not under traction or tension and has no tight curves or twists;
• the hose is not in contact with sharp objects or sharp corners;
• if the hose is not perfectly airtight and leaks gas, do not try and repair it: replace it with a new hose;
• verify that the hose is not beyond its life cycle (serigraphed on the hose itself).
CONNECTION USING RUBBER HOSES COMPLYING WITH THE CURRENT REGULATIONS IS
ONLY PERMITTED IF THE HOSE CAN BE INSPECTED ALONG ITS ENTIRE LENGTH.
