SAMPLING LOCATIONS Particulate samples are collected from the dilution tunnel at a point 20 feet from the tunnel entrance. The tunnel has two elbows and two mixing baffles in the system ahead of the sampling section. (See Figure 3.) The sampling section is a continuous 13 foot section of 6 inch diameter pipe straight over its entire length. Tunnel velocity pressure is determined by a standard Pitot tube located 60 inches from the beginning of the sampling section. The dry bulb thermocouple is located six inches downstream from the Pitot tube. Tunnel samplers are located 60 inches downstream of the Pitot tube and 36 inches upstream from the end of this section. (See Figure 1.) Stack gas samples are collected from the steel chimney section 8 feet ± 6 inches above the scale platform. (See Figure 2.) FIGURE 1 – DILUTION TUNNEL

SAMPLING METHODS PARTICULATE SAMPLING

Particulates were sampled in strict accordance with ASTM E2515-2011. This method uses two identical sampling systems with Gelman A/E 61631 binder free, 47-mm diameter filters. The dryers used in the sample systems are filled with “Drierite” before each test run. In order to measure first-hour emissions rates the a third filter set is prepared at one hour into the test run, the filter sets are changed in one of the two sample trains. The two filter sets used for this train are analyzed individually to determine the first hour and total emissions rate. INSTRUMENT CALIBRATION DRY GAS METERS At the conclusion of each test program the dry gas meters are checked against our standard dry gas meter. Three runs are made on each dry gas meter used during the test program. The average calibration factors obtained are then compared with the six-month calibration factor and, if within 5%, the six-month factor is used to calculate standard volumes. Results of this calibration are contained in Appendix D. An integral part of the post-test calibration procedure is a leak check of the pressure side by plugging the system exhaust and pressurizing the system to 10” W.C. The system is judged to be leak free if it retains the pressure for at least 10 minutes. The standard dry gas meter is calibrated every 6 months using a Spirometer designed by the EPA Emissions Measurement Branch. The process involves sampling the train operation for 1 cubic foot of volume. With readings made to .001 ft 3 , the resolution is .1%, giving an accuracy higher than the ±2% required by the standard. STACK SAMPLE ROTAMETER The stack sample rotometer is checked by running three tests at each flow rate used during the test program. The flow rate is checked by running the rotometer in series with one of the dry gas meters for 10 minutes with the rotometer at a constant setting. The dry gas meter volume measured is then corrected to standard temperature and pressure conditions. The flow rate determined is then used to calculate actual sampled volumes.

TEST REPORT FOR HY-C COMPANY, LLC Report No.: 103537042MID-001R5 Date: 10/30/18

GAS ANALYZERS The continuous analyzers are zeroed and spanned before each test with appropriate gases. A mid-scale multi-component calibration gas is then analyzed (values are recorded). At the conclusion of a test, the instruments are checked again with zero, span and calibration gases (values are recorded only). The drift in each meter is then calculated and must not exceed 5% of the scale used for the test. At the conclusion of each unit test program, a three-point calibration check is made. This calibration check must meet accuracy requirements of the applicable standards. Consistent deviations between analyzer readings and calibration gas concentrations are used to correct data before computer processing. Data is also corrected for interferences as prescribed by the instrument manufacturer’s instructions.

TEST METHOD PROCEDURES LEAK CHECK PROCEDURES

Before and after each test, each sample train is tested for leaks. Leakage rates are measured and must not exceed 0.02 CFM or 4% of the sampling rate. Leak checks are performed checking the entire sampling train, not just the dry gas meters. Pre-test and post-test leak checks are conducted with a vacuum of 10 inches of mercury. Vacuum is monitored during each test and the highest vacuum reached is then used for the post-test vacuum value. If leakage limits are not met, the test run is rejected. During, these tests the vacuum was typically less than 2 inches of mercury. Thus, leakage rates reported are expected to be much higher than actual leakage during the tests. TUNNEL VELOCITY/FLOWMEASUREMENT The tunnel velocity is calculated from a center point Pitot tube signal multiplied by an adjustment factor. This factor is determined by a traverse of the tunnel as prescribed in EPA Method 1. Final tunnel velocities and flow rates are calculated from EPA Method 2, Equation 6.9 and 6.10. (Tunnel cross sectional area is the average from both lines of traverse.)

Pitot tubes are cleaned before each test and leak checks are conducted after each test.

PM SAMPLING PROPORTIONALITY Proportionality was calculated in accordance with ASTM E2515-11. The data and results are included in Appendix C.

DEVIATIONS FROM STANDARD METHOD: Use of ALT-134 for output rate categories.

Original Report Issue

Updated Section 1 to include US EPA Alternate Test Method. Updated Section 3 to include US EPA Alternate Test Method. Updated Section 11 to correct emissions units from g/hr to lb/MMBtu Output. Added a copy of the US EPA Alternate Test Method as an Appendix. U.S. EPA requested a change to the Category 1 and Category 2 results. The average of tests 4 & 6 was changed to the average of tests 4 & 7, with test 6 used as the Category 2 results. The final particulate emissions rate changed from 0.118 lb/MMBtu to 0.106 lb/MMBtu, the CO emissions changed from 2.473 g/min to 1.935 g/min, and the overall direct efficiency changed from 51.7% to 50.1%. This required changes to all reported results including tables 1 through 4. Due to and error in interpretation of the U.S. EPA Alternate Test Method (ATM) dated July 26, 2018, all of the testing for the model SF1000E was redone in accordance with ALT-134 Alternate Test Method. This revised report includes the results of the new tests performed on the original test sample that was sealed and kept by HY-C Company. The results of this report are showing compliance to all 4 output categories outlined in CSA B415.1-2010. Added new models L1020 and X1020 as similar models. Adjusted coal bed weight from 6.8 lbs. to 4.5 lbs. and output rate from 19,900 Btu/hr to 17,495 Btu/hr for test #10. Changed from the EPA ALT-134 Alternate Test Method to the HY-C Alternate Test Method.

INTERTEK/WARNOCK HERSEY AIR FURANCE EMISSIONS AND EFFICIENCY TESTING LABORATORY OPERATING PROCEDURES pg. 2

I. APPLIANCE INSPECTION AND SET-UP A. Incoming Inspection

1. Check for completeness of unit including parts, accessories, installation and operating instructions, drawings and specifications, etc. Note any discrepancies or missing parts. 2. Check for shipping damage. If damage has occurred, notify the laboratory manager. In some cases repairs may be made, provided the manufacturer and laboratory manager concur that repairs will not affect the unit’s performance. If damage is irreparable, a new unit will need to be obtained. 3. Note whether unit is catalytic or non-catalytic. 4. Mark unit with manufacturer's name, model number, work order number, and date received. 5. If unit is safety listed, note label data including listing agency and serial number. B. Unit Set-Up 1. Prior to placing unit on scale, the scale must be turned on and allowed to warm up for 1-hour minimum. 2. Place unit on scale and align so chimney will be centered in hood. Record the weight of the unit and all accessories. (Do not weigh with chimney attached.) 3. Chimney and connector should be cleaned with a wire brush prior to mounting. Attach chimney and connector then seal all joints. Be sure the single wall stove pipe terminates and insulated pipe starts at proper level above scale platform. Chimney must be supported from scale so that it does not touch test enclosure or hood walls. 5. Measure firebox dimensions and record on appropriate data form. Make a three dimensional sketch of the firebox including firebrick, baffles, and obstructions. Calculate load area volume in cubic feet. See Section 8.2 of the CAN/CSA B415.1-2010 Performance Testing of Solid-Fuel-Burning Heating Appliances for details. 7. Plug thermocouples into data acquisition system jacks and verify that all instrumentation is working properly. 8. Dilution tunnel must be cleaned prior to each certification test series, and at anytime a higher burn rate follows a lower burn rate. 9. Install outlet air duct in accordance with the manufacturer’s requirements and section 5.3.2 of CAN/CSA B415.1-2010 Performance Testing of Solid-Fuel-Burning Heating Appliances. 10. Set duct static pressure to 0.2 in/wc or to the manufacturer’s specifications by reducing the duct outlet size uniformly.

II.

SAMPLING SYSTEMS SET-UP A. Gas Analysis 1. All instruments should be turned on and allowed to warm up for 1-hour minimum. 2. Prior to calibrating, make sure that the outlet pressure on each calibration gas bottle reads 10 PSI. Adjust flow meters at each gas analyzer to required flow. All gas analyzers (CO 2 , CO, O 2 ) are zeroed on nitrogen. The O 2 analyzer is spanned on air and set for 20.93%. CO 2 and CO analyzers are spanned with their respective gases. Calibrate analyzers as follows: a. With calibration switch at "SPAN", adjust all span controls to values specified on span gas label. b. Switch to "ZERO" and adjust zero controls to provide 0.00 readout on all analyzers. c. Repeat a. and b. until no further adjustment is required. d. Record these values on the appropriate data sheet. e. Switch to "CAL." and record all analyzer values. 3. Response time synchronization check. a. With switch at "SAMPLE" and no fire in unit, allow readings to stabilize (O 2 analyzer should read 20.93, CO and CO 2 should read 0.00). b. Switch to "CAL" setting and start the stopwatch. Note the time required for each unit to reach the calibration gas bottle value. If all three analyzers reach this value within 5 seconds of each other, synchronization is adequate. If not, contact the laboratory manager. Synchronization is adjusted by either internal instrument setting or adjustment of sample line length. c. Use section 8 of ASTM E2515 for procedures to check calibration of instruments. 4. Sample clean-up train. a. Load a new filter in 4-inch glass filter holder. b. Load four Impingers as follows:

#1: 100 ml. distilled or de-ionized water #2: 100 ml. distilled or de-ionized water #3: Empty #4: 200-300 grams Drierite.

G:\Hearth\EE - Emissions and Efficiencey\Furnace solid fuel\Lab Procedures for EPA Air Furnaces 11.11.16.doc

INTERTEK/WARNOCK HERSEY AIR FURANCE EMISSIONS AND EFFICIENCY TESTING LABORATORY OPERATING PROCEDURES pg. 4

c. Place Impingers in container and connect with greased "U TUBES". (Grease carefully on bottom half of ball joint so that grease will not get into tubes.) d. Connect filter to impinger #1 and sample line to impinger #4.

e. Connect stack probe to filter. f. Leak check system as follows: 1) Plug probe. 2)

Turn on sample system and increase flow rate slowly. Set vacuum-adjust valve to obtain a vacuum of 10 inches mercury.

3)

4) If sapphire float in rotometer does not stabilize below 10 on scale, system must be resealed. 5) Repeat leak-check procedure until satisfactory results are obtained. 6) Unplug probe slowly, then decrease flow rate slowly before shutting off system. g. Just prior to starting test, fill impinger container with ice. B. Dilution Tunnel Sample Train Set-Up: 1. Filters and holders. a. Clean probes and filter holder front housings carefully and desiccate to a constant weight prior to use. b. Filters and filter probe combinations should be numbered and labeled prior to use. c. Weigh desiccated filters and probe filter units on analytical balance. Record the weights on the appropriate form. Note that the probe and front half of the front filter holder is to be weighed as a unit. d. Carefully assemble the filter holder units and connect to sampling systems. 2. Leak checking. a. Each sample system is to be checked for leakage prior to inserting probes in tunnel. b. Plug probes and start the samplers. Adjust pump bypass valve to produce a vacuum reading of 10 inches mercury. NOTE: During test, highest vacuum recorded is required for posttest leak check. c. Allow vacuum indication to stabilize at 10" mercury, record dry gas meter readings, (DGM 1 , DGM 2 ). At a convenient DGM value start stopwatch. Time for 1 minute then stop vacuum pumps. Record dry gas meter readings again, (DGM 3 , DGM 4 ). NOTE: If rotometer ball is floating above the 5-mm mark, system is leaking too much and all seals should be checked.

INTERTEK/WARNOCK HERSEY AIR FURANCE EMISSIONS AND EFFICIENCY TESTING LABORATORY OPERATING PROCEDURES pg. 5

d. Calculate leakage rate as follows. System 1: DGM3-DGM 1 = CFM 1 System 2: DGM4-DGM 2 = CFM 2

If CFM 1 or CFM 2 is greater than 0.02 cfm, or 1 S greater than 0.04 x Sample Rate, leakage is unacceptable and system must be resealed. For most tests the sample rate will be 0.25 cfm, thus leakage rates in excess of 0.04 x 0.25 = 0.010 cfm are not acceptable. e. To prevent contamination, do not insert probes in tunnel until the start of the test run. TEST CONDUCT A. Pre-Test Fuel Load 1. Using oak wood, operate normally until the unit is heated and has cycled at least 2 times. Then remove all contents and zero scale 2. Reload with oak wood (pieces approximately 2” thick) and allow to burn down to specified coal bed weight. B. Test Fuel Load 1. Determine optimum load weight by multiplying loading area volume (ft 3 ) by 10lbs/ft 3 . This is the ideal load weight. 2. Test load fuel shall be red or white oak cordwood with a dimension of 20- inches (± 4”). Moisture content of each piece needs to be within 18-28%, with the overall average to be between 18-28%. 3. Weigh out test load and adjust weight by shortening or lengthening all pieces equally if necessary. 4. Measure and record moisture content of each fuel piece (using five total measurements). Determine if fuel load moisture content is within required range (18-28%). If not, construct new fuel pieces using wood with required moisture content. Contact laboratory manager if you cannot find suitable pieces. C. Unit Start-Up 1. With all doors and air controls closed, zero draft magnehelic using screw located at bottom of meter. 2. Before lighting a fire turn on dilution tunnel and set flow rate to 60 scfm. 3. Check draft imposed on cold stove. All inlets must be closed and a draft gauge in the chimney. If draft is greater than 0.005 inches water column, adjust tunnel to stack gap until draft is less than 0.005 inches water column.

4. With hot wire anemometer check for ambient airflow around unit (must be less than 50 ft/min). 5. Zero scale and start fire with newspaper and kindling. (Make sure stack sample probe is on the unit.) 6. Once kindling is burning well, add preload fuel. Operate at high fire for sufficient time to get fuel load burning well. Then adjust settings to intended test run levels. 7. Perform the dilution tunnel traverse as prescribed in ASTM #2515, Section 9.3. (Pitot tube should be carefully cleaned prior to each test.) 8. Pretest load must burn until the unit has cycled at least 2 times. 9. Stir fire often during preburn (after a reading) to get a good coal bed. Fire can only be raked once (door open 1 minute or less) during the 15 minutes prior to the start of the test. 10.Traverse the outlet duct velocity with a vane anemometer and enter into the spreadsheet. D. Test Run 1. Stack gas analyzers should be on and in the sample mode. 2. When the fuel bed is between 10-20% of the test load weight the test is to be started. a. Insert the sample probes into the tunnel being careful not to hit sides of tunnel with probe tip. b. Check tunnel Pitot tube for proper position. c. Record initial readings. d.
