CSA B415.1:22

1 Scope 1.1 Product range This Standard specifies requirements for performance testing of solid-biofuel-burning heating appliances, including maximum emission rates. 1.2 Reporting metrics This Standard specifies a method for determining a) heat outputs; b) appliance efficiencies; c) emission levels and composition; and d) electrical energy consumption and production. 1.3 Product types This Standard applies to a) Type 1: site-built heating appliances; b) Type 2: room heaters; c) Type 3: forced-air furnaces; d) Type 4: hydronic heating appliances; and e) Type 5: hybrid heating appliances. Note: Typically, units tested under this Standard will have outputs less than 150 kW (500 000 BTU/h). For the purposes of this Standard, solid-biofuel-burning appliances include manually and automatically fuelled systems (including add-ons and combinations). 1.4 Fuels This Standard covers appliances that burn biomass fuels such as a) cordwood; b) wood chips; c) wood pellets; d) sawdust; e) firelogs; f) wood, paper, and other biomass pellets and briquettes; and g) non-woody solid biofuels from agricultural, herbaceous, and fruit origins such as kernel corn, other grains, cherry pits, and pelletized or briquetted straw, hay, and corn stover. 1.5 Products not covered This Standard does not apply to a) factory-built fireplaces intended to be used primarily for aesthetic enjoyment and not as space heaters; and b) solid fossil fuel appliances. 1.6 Emissions limits Emission limits are expressed in both g/h and g/MJ (output) at the option of the manufacturer. Forced- air furnace and hydronic heater emission limits are expressed in g/MJ (output) only, with the addition that indoor automatically fed hydronic heater emissions are expressed in mg/Nm3 at a delivered minimum thermal efficiency when tested to CEN EN 303-5. 1.7 Units of measurement The values given in SI units are the units of record for the purposes of this Standard. Where values are given in parentheses, they are for information and comparison only. 1.8 Terminology In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.
