Scope1.1 This guide covers the design and construction of solidfuel burning masonry heaters. It provides dimensions for siteconstructed masonry he
3、ater components and clearances thathave been derived by experience and found to be consistentwith the safe installation of those masonry heaters.1.2 Values given in SI units are to be regarded as standard.Inch/pound units may be rounded (see IEEE/ASTM SI-10).Alldimensions are nominal unless specific
4、ally stated otherwise.All clearances listed in this guide are actual dimensions.1.3 This guide applies to the design and construction ofmasonry heaters built on-site with the components and mate-rials specified herein. It does not apply to the construction/installation requirements for component sys
5、tems that havebeen safety tested and listed. The requirements for listedmasonry heater systems are specified in the manufacturersinstallation instructions.1.4 The design and construction of solid fuel burningmasonry heaters shall comply with applicable building codes.2.

Remove wooden forms used during theconstruction of hearth and hearth extension once constructionis completed.5.4.2 Closed Door FireboxesWith a masonry heater de-signed to be fired with a closed door of glass or metal, thehearth extension shall be at least 500
48、 mm (20 in.) in front of thefacing materials and at least 300 mm (12 in.) beyond each sideof the masonry heater opening. When a raised hearth of at least200 mm (8 in.) in height is used and the hearth extension islocated at the base of the door, the hearth extension can bereduced to 400 mm (16 in.)
49、in front of the facing materials.5.4.3 Open Fireboxes:5.4.3.1 Where the firebox opening is less than 0.6 m2(6 ft2),the hearth extension shall extend at least 400 mm (16 in.) infront of the facing materials and at least 200 mm (8 in.) beyondeach side of the firebox opening.5.4.3.2 Where the firebox opening is 0.6 m2(6 ft2) or larger,the hearth extension shall extend at least 500 mm (20 in.) infront of the facing materials and at least 300 mm (12 in.)beyond each side of the firebox opening.5.4.4 Where a firebox opening overhangs a floor
