1401,METHOD 28 ) CERTIFICATION AND AUDITING,OF WOOD HEATERS,NOTE: This method does not include all of the,specifications (e.g., equipment and supplies) and procedures,(e.g., sampling and analytical) essential to its,performance. Some material is incorporated by reference,from other methods in this part. Therefore, to obtain,reliable results, persons using this method should have a,thorough knowledge of at least the following additional test,methods: Method 1, Method 2, Method 3, Method 4, Method 5,Method 5G, Method 5H, Method 6, Method 6C, and Method 16A.,1.0 Scope and Application.,1.1 Analyte. Particulate matter (PM). No CAS number,assigned.,1.2 Applicability. This method is applicable for the,certification and auditing of wood heaters, including pellet,burning wood heaters.,1.3 Data Quality Objectives. Adherence to the,requirements of this method will enhance the quality of the,data obtained from air pollutant sampling methods.,2.0 Summary of Method.,2.1 Particulate matter emissions are measured from a,wood heater burning a prepared test fuel crib in a test,facility maintained at a set of prescribed conditions.,1402,Procedures for determining burn rates and particulate,emission rates and for reducing data are provided.,3.0 Definitions.,3.1 2 × 4 or 4 × 4 means two inches by four inches or,four inches by four inches (50 mm by 100 mm or 100 mm by 100,mm), as nominal dimensions for lumber.,3.2 Burn rate means the rate at which test fuel is,consumed in a wood heater. Measured in kilograms or lbs of,wood (dry basis) per hour (kg/hr or lb/hr).,3.3 Certification or audit test means a series of at,least four test runs conducted for certification or audit,purposes that meets the burn rate specifications in Section,8.4.,3.4 Firebox means the chamber in the wood heater in,which the test fuel charge is placed and combusted.,3.5 Height means the vertical distance extending,above the loading door, if fuel could reasonably occupy that,space, but not more than 2 inches above the top (peak,height) of the loading door, to the floor of the firebox,(i.e., below a permanent grate) if the grate allows a 1-inch,diameter piece of wood to pass through the grate, or, if,not, to the top of the grate. Firebox height is not,necessarily uniform but must account for variations caused,1403,by internal baffles, air channels, or other permanent,obstructions.,3.6 Length means the longest horizontal fire chamber,dimension that is parallel to a wall of the chamber.,3.7 Pellet burning wood heater means a wood heater,which meets the following criteria: (1) The manufacturer,makes no reference to burning cord wood in advertising or,other literature, (2) the unit is safety listed for pellet,fuel only, (3) the unit operating and instruction manual,must state that the use of cordwood is prohibited by law,and (4) the unit must be manufactured and sold including the,hopper and auger combination as integral parts.,3.8 Secondary air supply means an air supply that,introduces air to the wood heater such that the burn rate is,not altered by more than 25 percent when the secondary air,supply is adjusted during the test run. The wood heater,manufacturer can document this through design drawings that,show the secondary air is introduced only into a mixing,chamber or secondary chamber outside the firebox.,3.9 Test facility means the area in which the wood,heater is installed, operated, and sampled for emissions.,3.10 Test fuel charge means the collection of test,fuel pieces placed in the wood heater at the start of the,emission test run.,1404,3.11 Test fuel crib means the arrangement of the test,fuel charge with the proper spacing requirements between,adjacent fuel pieces.,3.12 Test fuel loading density means the weight of,the as-fired test fuel charge per unit volume of usable,firebox.,3.13 Test fuel piece means the 2 × 4 or 4 × 4 wood,piece cut to the length required for the test fuel charge,and used to construct the test fuel crib.,3.14 Test run means an individual emission test which,encompasses the time required to consume the mass of the,test fuel charge.,3.15 Usable firebox volume means the volume of the,firebox determined using its height, length, and width as,defined in this section.,3.16 Width means the shortest horizontal fire chamber,dimension that is parallel to a wall of the chamber.,3.17 Wood heater means an enclosed, woodburning,appliance capable of and intended for space heating or,domestic water heating, as defined in the applicable,regulation.,4.0 Interferences. [Reserved],5.0 Safety.,1405,5.1 Disclaimer. This method may involve hazardous,materials, operations, and equipment. This test method may,not addre……
