VENTILATION2.1 This appliance requires a constant supply of air to maintainproper combustion and effective flue performance.2.2 An inadequate air supply can result in poor combustion andsmoke entering the room which is potentially dangerous.2.3 This supply of air can come from either:—The natural leakage of air into the room in which theproduct is fitted.—Purpose provided ventilation.—Some Stovax appliances can also be fitted with anoptional outdoor air kit which allows air to be drawn infrom the outside.Modern building techniques have reduced the amount of airthat leaks in or out of a house. A modern construction withan air tightness of less than 5m 3 per hour per m 2 requires anair vent for ALL solid fuel appliances including those with arated heat output of less than 5kW.NOTE: The air leakage of a modern house is tested at thecompletion of construction and a certificate issued confirmingthis.2.4 The amount of air required must comply with local buildingregulations and the rules in force.2.5 If spillage is detected during commissioning then there maybe insufficient natural ventilation and an additional air supplywill be necessary.2.6 Many older buildings are sufficiently ventilated by naturalleakage of air to provide suitable air supply for an applianceof 5kW output or less.17
