This report includes summaries of all data necessary to determine compliance with the regulations. Raw data, calibration records, intermediate calculations, drawings, specifications and other supporting information are contained in appendices to this report.
II. SUMMARY II.A PRETEST INFORMATION
A sample was submitted to Intertek directly from the client. The sample was not independently selected for testing. The test unit was received at Intertek in Middleton, WI on June 6, 2016 and was shipped via the client. The unit was inspected upon receipt and found to be in good condition. The unit was set up following the manufacturer's instructions without difficulty. Following assembly, the unit was placed on the test stand. Prior to beginning the emissions tests, the unit was operated for a minimum of 10 hours at high-to-medium burn rates to condition the heater. This conditioning burn was performed by HY-C and the documents are included in the final report. The unit was found to be operating satisfactory during this break-in. The 10 plus hours of pre-burning were conducted from May 26, 2016 to May 28, 2016. The fuel used for the break-in process was cordwood. Following the pre-burn break-in process the unit was allowed to cool and ash and residue was removed from the firebox. The unit's chimney system and laboratory dilution tunnels were cleaned using standard wire brush chimney cleaning equipment. On June 6, 2016 the unit was set-up for testing.

SAMPLING SYSTEMS
IV.A. 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.)

V. SAMPLING METHODS
V.A. 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.
VI. QUALITY ASSURANCE
VI.A. INSTRUMENT CALIBRATION
VI.A. (1).
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.

VI.A.(2).
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.
VI.A.(3).
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 inter- ferences as prescribed by the instrument manufacturer’s instructions.
VI.B. TEST METHOD PROCEDURES
VI.B.(1).
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.

Page 15 of 15
VI.B.(2).
TUNNEL VELOCITY/FLOW MEASUREMENT
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.
VI.B.(3). PM SAMPLING PROPORTIONALITY
Proportionality was calculated in accordance with ASTM E2515-11. The data and results are included in Appendix C.
VII. CONCLUSION
This test demonstrates that this unit is an affected facility under the definition given in the regulation. The emission rate of 0.368 g/hr meets the EPA requirements for the Step 1 limits. Model FC1500 was tested as a representative sample of similar model SF2600. SF2600 is identical to the FC1500, with the only difference being the color. SF Series is sold under the Shelter Furnace name and the FC Series is sold under the Fire Chief Industries name. INTERTEK TESTING SERVICES NA
