Heaters. All testing and associated procedures were conducted at PFS-TECO’s

Portland Laboratory on 4/23/2018. PFS-TECO’s Portland Laboratory is located at 11785

SE Highway 212 – Suite 305, Clackamas, Oregon 97015. Testing procedures followed

ASTM E2779. Particulate sampling was performed per ASTM E2515, Standard Test

Method for Determination of Particulate Matter Emissions Collected by a Dilution

Tunnel.

certification and auditing of wood heaters pursuant to subpart AAA of 40 CFR Part 60,

New Source Performance Standards for Residential Wood Heaters and subpart QQQQ

of 40 CFR Part 60, Standards of Performance for New Hydronic Heaters and Forced Air

Furnaces, Methods 28R, 28WHH, 28 WHH-PTS, and all methods listed in Sections

60.534 and 60.5476. PFS-TECO holds EPA Accreditation Certificate Numbers 4 and

4M (mobile). PFS-TECO is accredited by IAS to ISO 17020:2012 “Criteria for Bodies

Laboratories”, and by Standards Council of Canada to ISO 17065:2012 “Requirements

for Bodies Operating Product Certification Systems”.

The following people were associated with the testing, analysis and report writing

associated with this project.

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.
