Bosch Appliances 24I RSF manual Siting The Flue, Air Supply, Position AIR from AIR Direct

5. Siting The Flue

See Fig. 3.

5.1The flue must be installed as specified in BS 5440:Part 1.

5.2The terminal must not cause an obstruction nor the discharge cause a nuisance.

5.3If the terminal is fitted within 850mm of a plastic or painted gutter or within 450mm of painted eaves then an aluminium shield at least 750mm long should be fitted to the underside of the gutter or painted surface.

5.4If a terminal is fitted less than 2 metres above a surface to which people have access then a guard must be fitted. See Section 2.9.

5.5The terminal guard must be evenly spaced about the flue terminal and fixed to the wall using plated screws.

5.6In certain weather conditions a terminal may steam and siting where this could cause a nuisance should be avoided.

5.7Take care to ensure that combustion products do not enter ventilated roof voids.

6. Air Supply

6.1 The appliance does not require a separate vent for combustion air.

6.2The appliance can be fitted in a cupboard with no vents for cooling but the minimum clearances must be increased to those given below (note the clearances at the front are for a removable panel e.g. a door).

Above the Turret	20mm
In front	250mm
Below	200mm
Right-hand side	75mm
Left-hand side	75mm

6.3If the appliance is to be fitted in a cupboard or compartments with less clearance than those above (minimum clearances given in Section 4. Siting The Appliance) then permanent vents for cooling are required. One at high level and one at low level, either direct to outside air or to a room. Both vents must pass to the same room or be on the same wall to the outside air.

6.4The minimum free areas required are given below.

POSITION OF	AIR FROM	AIR DIRECT
AIR VENTS	THE ROOM	FROM OUTSIDE
HIGH LEVEL	270cm2	135cm2
LOW LEVEL	270cm2	135cm2
