Introduction
US Stove of South Pittsburg, TN contracted with PFS-TECO to perform EPA certification
testing on SP1000E 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 heat setting, per ASTM E2779
•Prior to start of testing, the dilution tunnel was cleaned with a steel brush.
•A separate, independent sample train was utilized to determine 1st hour emissions.
•A single test was performed in accordance with EPA ALT-146 burn rate settings:
o1 Hour at Maximum Burn Setting
o2 Hours at Medium Burn Setting (less than the mid-point of the high and low
rates)
o3 Hours at Minimum Burn Setting

Results
The integrated test run emission rate for test Run 1 was measured to be 1.0 g/hr with a
Higher Heating Value efficiency of 75% and a CO emission rate of 0.19 g/min. The
calculated first hour particulate emission rate was 3.2 g/hr. The US Stove Model
SP1000E 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 5/19/2023 as an attempted integrated test run per EPA ALT-
146/ ASTM E2779. The overall test duration was 360 minutes. The particulate emissions
rate for the integrated test run was 1.0 g/hr. The run had an overall HHV efficiency of
75%. A separate filter train C was run for the first hour of the run only. 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.

Appliance Description
Model(s): SP1000E
Appliance Type: Pellet-Fired Room Heater
Additional Models: Certification testing was performed on the model SP1000E. This
model series is branded under a several different names, including the KP1000E,
AP1000E , and the US1000E. Models under these various brand names utilize the same
basic design with respect to performance and emissions controls. All models listed above
are presumed to have the same emissions performance as the test specimen provided
for certification testing.
Air Introduction System: A variable speed combustion fan forces air into the firebox
through holes in the bottom of the firepot.
Combustion Control: A control panel on the side of the unit is used to select burn rates,
which are varied by automatic modulation of the combustion fan and feed system. An
automatically controlled distribution bower is also installed.
Fueling System: An inclined auger driven by a gear motor, meters pellets through a drop
tube (over feed) to a fire pot in the firebox.
Baffles: N/A
Flue Outlet: Venting is through a 3" diameter steel pipe, which exits through the back of
the unit. The unit is designed for optional connection to a 6” flue.

Sampling Locations and Descriptions
Sample ports are located 16.5 feet downstream from any disturbances and 2 feet
upstream from any disturbances. Flow rate traverse data was collected 8 feet
downstream from any disturbances and 4 feet upstream from any disturbances. (See
below).

Project # 23-114 Model: SP1000E

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.
