Volume Three Appendix 8 Appendix 8 Discharge to Air Schedule 1 – Emission Requirements Small-scale Solid Fuel Burning Appliances. Small-scale solid fuel burning appliances must: (a) Emit no more than 1.5 grams of total suspended particulate per kilogram of fuel burned, calculated by averaging the total suspended particulate emissions for high, medium and low burn rates, when tested in accordance with AS/NZS4012:1999 and AS/NZS4013:1999 or the functional equivalent for non-batch fed appliances. Where the nominated test fuel is wood then the test must be carried out using softwood in accordance with the requirements of AS/NZS 4014.2:1999; and (b) Have a thermal efficiency, for space heating only, as described in AS/NZS 4013:1999, of 65% or greater; and (c) Not be modified in any way so as to alter the specifications of the heating device from those tested and stated in a) and b); and (d) Be maintained in good operational order and operated in accordance with the manufacturer’s instructions (so long as those do not mandate operation that would lead to output that does not comply with a) or b), and be operated with the door shut in the case of enclosed appliances; and (e) Be capable of being operated on a high, medium and low burn rate. Schedule 2 – Stack Requirements Small-scale Solid Fuel Burning Appliances The discharge into air from any device installed after 9 June 2016 must be to the atmosphere via an emission stack which in all cases extends vertically not less than 4.6m above the floor protector under the appliance, and: (a) where the stack is within 3m horizontally, or closer, to the highest point of the roof of the building, the stack must protrude at least 600mm above the high point of the roof; or (b) where the stack is further than 3m horizontally from the highest point of the roof of the building, the stack must protrude at least 1000mm above the point of roof penetration; and (c) the stack must be sufficiently high so that no building (including the building into which the appliance is being installed), substantial structure or any land, lies in or above a horizontal plane with a radius of 3m drawn around the top of the stack; and (d) the discharge must be directed vertically into air (although cowls or weather protectors are permitted).
