Introduction
United States Stove Company of South Pittsburg, TN, contracted with PFS-TECO to
perform EPA certification testing on KP60 Pellet-Fired Room Heater. All testing was
performed at PFS-TECO’s Portland Laboratory. Testing was performed by Mr.
Sebastian Button.
Notes
• Prior to start of testing, 50 hours of conditioning was performed by the
manufacturer at a medium test setting per ASTM E2779
• Prior to start of testing, the dilution tunnel was cleaned with a steel brush.
• Front 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 The medium burn rate setting used was the same as the low burn rate
setting, as that is the only setting the yields a burn rate of <50% of the
high burn rate, as required by ASTM E2779.

Results
The integrated test run emission rate for test Run 1 was measured to be 1.46 g/hr with
a Higher Heating Values efficiency of 66.2% and a CO emission rate of 0.29
g/min. The calculated first hour particulate emission rate was 2.01 g/hr. The United
States Stove Company Model KP60 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 4/23/2018 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 1.46 g/hr. The run had an overall HHV efficiency of 66.2%. The
Trian A front filter was changed at 1 hr.
Upon completion of testing, lab analysis of the rear sample filters for the Train A post 1st
hour and Train B samples yielded a negative number (-0.1 mg). This was the result of a
portion of the filter attaching to O-ring seal and pulling away from the filter. This is
reflected in the weight of the catch on the O-rings for this given run (0.5 mg and 0.9 mg,
for Trains A and B, respectively). While this type of result is somewhat infrequent, it is
with this type of occurrence in mind that O-rings are also included in the test analysis.
The negative values report during this run should be considered valid and appropriately
handled. All other test results were appropriate and valid. There were no other
anomalies and all test 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

Appliance Description
Model(s): KP60, AP60, and VG60
Additional Models Discussion: Certification testing was performed on the model
KP60. The 60 series is also offered branded under several different names, including
Vogelzang and Ashely as the VG60 and AP60, respectively. Models under these
various brand names utilize the same basic design with respect to performance and
emissions controls. All models listed are presumed to have the same emissions
performance as the test specimen provided for certification testing.
Appliance Type: Pellet-Fired Room Heater
Air Introduction System: Air enters the burn chamber by being pulled though the
firepot, via the exhaust blower, see air flow diagram in Appendix D.
Combustion Control: Feed rate is electronically controlled via user-selectable controls.
Baffles: N/A
Flue Outlet: 3-inch exhaust outlet located on the bottom/rear of the appliance.
