Results

The integrated test run emission rate for test Run 1 was measured to be 0.54 g/hr with a
Higher Heating Values efficiency of 80.2% and a CO emission rate of 0.03 g/min. The
calculated first hour particulate emission rate was 1.26 g/hr. The Sherwood Industries
Ltd. Model Enviro Mini 2 Pellet-Fired Room Heater meets the 2020 PM emission standard
of ≤ 2.0 g/hr per CFR 40 part 60, §60.532 (b).
Detailed individual run data can be found in Appendix A submitted with this report.

Test Run Narrative

Run 1

Run 1 was performed on 4/14/2021 as an attempted integrated test run per ASTM E2779.
The overall test duration was 360 minutes. The particulate emissions rate for the
integrated test run was 0.54 g/hr. The run had an overall HHV efficiency of 80.2%. The
train A front filter was changed at 1 hr. All test results were appropriate and valid and the
burn rate requirement for the integrated test run were achieved. There were no anomalies
and all criteria were met.
