4.1 This guide can be used by code officials, architects, and other interested parties to evaluate the design and construction of masonry heaters. It is not restricted to a specific method of construction, nor does it provide all specific details of construction of a masonry heater. This guide does provide the principles to be followed for the safe construction of masonry heaters.4.2 This guide is not intended as a complete set of directions for construction of masonry heaters.4.3 Construction of masonry heaters is complex, and in order to ensure their safety and performance, construction shall be done by or under the supervision of a skilled and experienced masonry heater builder.51.1 This guide covers the design and construction of solid fuel burning masonry heaters. It provides dimensions for site constructed masonry heater components and clearances that have been derived by experience and found to be consistent with 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). All dimensions are nominal unless specifically stated otherwise. All clearances listed in this guide are actual dimensions.1.3 This guide applies to the design and construction of masonry heaters built on-site with the components and materials specified herein. It does not apply to the construction/installation requirements for component systems that have been safety tested and listed. The requirements for listed masonry heater systems are specified in the manufacturer’s installation instructions.1.4 The design and construction of solid fuel burning masonry heaters shall comply with applicable building codes.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This test method is used for determining average emission rates and average emission factors for pellet heaters.5.1.1 The emission factor is useful for determining emission performance during product development.5.1.2 The emission factor is useful for the air quality regulatory community for determining compliance with emission performance limits.5.1.3 The emission rate may be useful for the air quality regulatory community for determining impacts on air quality from pellet heaters.5.2 The reporting units are grams of particulate per hour and grams of particulate per kilogram of dry fuel.5.2.1 Appropriate reporting units for comparing emissions from all types of solid fuel fired appliances: g/kg.5.2.2 Appropriate reporting units for predicting atmospheric emission impacts: g/h or g/MJ.1.1 This test method covers the fueling and operating protocol for determining particulate matter emissions from fires in pellet or other granular or particulate biomass burning room heaters and fireplace inserts.1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This test method is used for determining emission rates and emission factors for wood heaters.5.1.1 The emission factor is useful for determining emission performance during product development.5.1.2 The emission factor is useful for the air quality regulatory community for determining compliance with emission performance limits.5.1.3 The emission rate may be useful for the air quality regulatory community for determining impacts on air quality from wood heaters.5.2 The reporting units are grams of particulate per hour, grams of particulate per kilogram of dry fuel and grams of particulate per megajoule of heat output.5.2.1 Appropriate reporting units for comparing emissions from all types of solid fuel fired appliances: g/kg.5.2.2 Appropriate reporting units for predicting atmospheric emission impacts: g/h or g/MJ.5.3 The fuel load specified in this test method is a lumber crib of uniform dimensions, identical to that specified in EPA Method 28. Cribs were specified in EPA Method 28 to provide a reproducible and repeatable test method. In normal operation the majority of fuel used by consumers is cordwood with irregular shapes and dimensions. Very little data exists to indicate whether or not the fuel cribs specified in this standard yield results that are predictive of performance using cordwood fuel. This standard, therefore, includes Annex A1 which provides a fueling procedure using cordwood. It is provided so that those interested in measuring emissions performance with cordwood will have a consistent method to follow. A comparative database using the two fueling procedures will provide data to determine whether test results using crib fuel correlate to test results using cordwood fuel.1.1 This test method covers the fueling and operating protocol for determining particulate matter emissions from wood fires in wood-burning room heaters and fireplace inserts as well as determining heat output and efficiency.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
