Notes
• Prior to start of testing, 50 hours of conditioning was performed at a medium burn
setting per ASTM E2779
• Prior to start of testing, the dilution tunnel was cleaned with a steel brush.
• Filters were changed on sample train A at one hour after the test began.
• A single, integrated test run, in accordance with ASTM E2779 was performed:
o 1 Hour at Maximum Burn Setting
o 2 Hours at Medium Burn Setting (Defined as <50% of Maximum Burn Rate)
o 3 Hours at Minimum Burn Setting

Results
The integrated test run emission rate for test Run 1 was measured to be 1.5 g/hr with a
Higher Heating Values efficiency of 76% and a CO emission rate of 0.5 g/min. The
calculated first hour particulate emission rate was 2.4 g/hr. The United States Stove
Company Model KP5513 Pellet-Fired Room Heater meets the 2020 PM emission
standard of ≤ 2.0 g/hr per CFR 40 part 60, §60.532 (b).

Test Run Narrative
Run 1
Run 1 was performed on 12/2/2021 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 1.5 g/hr. The run had an overall HHV efficiency of 76%. Sample
train A 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.
Test Conditions Summary
Testing conditions for all runs fell within allowable specifications of ASTM E2779 and
ASTM E2515. A summary of facility conditions, fuel burned, and run times is listed below.

Sampling Methods
ASTM E2515 was used in collecting particulate samples. The dilution tunnel is 12 inches
in diameter. All sampling conditions per ASTM E2515 were followed. No alternate
procedures were used.
Analytical Methods Description
All sample recovery and analysis procedures followed ASTM E2515 procedures. At the
end of each test run, filters, O-Rings and probes were removed from their housings,
dessicated for a minimum of 24 hours, and then weighed at 6 hour intervals to a
constant weight per ASTM E2515-11 Section 10.
Calibration, Quality Control and Assurances
Calibration procedures and results were conducted per EPA Method 28R, ASTM E2515-
11 and ASTM E2780-10. Test method quality control procedures (leak checks, volume
meter checks, stratification checks, proportionality results) followed the procedures
outlined.
Appliance Sealing and Storage
Upon completion of testing, the appliance was secured with metal strapping and the seal
below was applied, the appliance was then returned to the manufacturer’s location at:
227 Industrial Park Road, South Pittsburg, TN 37380 for archival.
