For the purpose of this Statutory Order: 1) "Combustion plant" means a technical system in which solid fuels are burned with a view to using the generated heat, including pellet burners for separate retrofitting for such plants. Other burners are considered to be part of the combustion plant. 2) "Space heater" means a combustion plant with doors with or without a water tank, designed to directly heat the surroundings, including wood-burning stoves, fireplace inserts, pellet stoves, masonry stoves, sauna stoves and similar fixed energy production plants. 3) "Central heating boiler" means a combustion plant with a boiler for heating water for consumption and/or central heating, designed not to directly heat the space where it is located. 4) "Fireplace insert" means a plant with or without a door, designed to be installed in the opening to a fireplace or the firebox of an open fireplace. 5) "Pellet burner (stoker)" means a device for automatic burning of wood pellets, wood chips and similar for which there may be different types of control; on-off, mechanical, modulating or with several steps, into which pellets can be fed horizontally, from above or from underneath. 6) "Masonry stove" means an enclosed brick wood-burning stove with a long smoke tube system and a large volume in order to give heat for a long time. 7) "Tiled stove" means a brick wood-burning stove covered with tiles, flags or porcelain.

Annex 4 Distance to nearest neighbour and the significance of dimensioning discharge The tables below must be used to determine within which distances to nearest neighbour it is necessary to calculate the dimensioning of discharge from straw burners, where Hs is the height of the chimney ( skorsten in Danish) measured from the ground level, and Hb is the height of the building on which the chimney is placed, measured from ground level. Choose the combination of height of building and chimney which is closest to the situation that will apply when the straw burner is installed. The relevant point on the current curve for a given straw burner is determined on the basis of the nominal output (kw) of the plant stated on the x-axis, and distance from discharge to nearest neighbour stated in metres on the y-axis. In each table, the height of the building (Hb) is constant, whereas the height of the chimney (Hs) varies with four or five heights, and this results in four-five curves.
