INTRODUCTION
GHP Group, Inc. retained
OMNI
to perform U.S. Environmental Protection Agency (EPA)
certification testing on the Large Wood Stove Freestanding woodstove. The Large Wood Stove
Freestanding wood stove is a Non-Catalytic-type room heater. The firebox is constructed of
mild steel. Usable firebox volume was measured to be 2.00 cubic feet and the stove is vented
through 6” flue collar located on the stove top.
Testing was performed at Nelke Consulting, altitude of the laboratory is 500 feet above sea level.
The unit was received in good condition and logged in on 5/4/20, then assigned and labeled with
OMNI
ID #2409.
OMNI
representative Bruce Davis conducted the certification testing and
completed all testing by May 6, 2020.
This report is organized in accordance with the EPA-recommended outline and is summarized in
the Table of Contents immediately preceding this section. The results in this report are limited to
the item submitted.
SAMPLING PROCEDURE
The Large Wood Stove wood stove was tested in accordance with the U.S. EPA 40 CFR Part 60,
Subpart AAA – Standards of Performance for New Residential Wood Heaters using ASTM
E2515, EPA Alt-125, and ASTM E3053. Particulate emissions were measured using sampling
trains consisting of two Teflon coated 47mm filters (front and back). See Appendix B for details
on EPA Alt-125.
The model Large Wood Stove was tested for thermal efficiency and carbon monoxide (CO)
emissions in accordance with CSA B415.1-10 using Cherry cordwood.
SUMMARY OF RESULTS
The weighted average emissions of the three test runs included in the results indicate a
particulate emission rate of 1.48 grams per hour. Particulate emissions used in the weighted
average were sampled on only one of the high burn fuel loads, test 3 was conducted to generate a
coal bed for test number 4. The Large Wood Stove results are within the EPA 2020 emissions
limit of 2.5 g/h for affected products tested with cordwood.
The proportionality results for all 3 test runs were acceptable. Quality check results for each test
run are presented in Section 2 of this report.
