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.
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 ASTM E2515. Final tunnel velocities and flow rates are calculated from E2515, Equations 3 and 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. The data and results are included in Appendix C.
VII. RESULTS AND OBSERVATIONS
The Model WHS2000 has been found to be in compliance with the applicable performance and construction requirements of the following criteria: “ Annex A1 Modified test method for wood-fired hydronic appliances that utilize thermal storage of ASTM E2618-13 Measurement of particulate emissions and heating efficiency of outdoor solid fuel-fired hydronic heating appliances ” The model WHS2000V was the model tested, which is configured with a vertical flue located at the top back of the unit. Model WHS2000H is an identical model with the only difference being that the flue exits horizontally out the back of the unit. The model WHS2000H does contain slightly more water in the vessel due to the flue area is not notched out for the vertical flue exit.
