INTRODUCTION
Travis Industries, Inc. retained OMNI to perform U.S. Environmental Protection Agency (EPA)
certification testing on the Liberty Freestanding woodstove. The Liberty Freestanding wood
stove is a Non-Catalytic-type room heater. The firebox is constructed of mild steel. Usable
firebox volume was measured to be 3.65 cubic feet and the stove is vented through 6” flue collar
located on the stove top.
Testing was performed at Travis Industries. The altitude of the laboratory is 108 feet above sea
level. The unit was received in good condition and logged in on 9/9/2019, then assigned and
labeled with OMNI ID #2384. OMNI representative Bruce Davis conducted the certification
testing and completed all testing by September 12, 2019.
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 Answe 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 EPA
Method 28R, ASTM E2515 and EPA Alt-125, ASTM E3053. Particulate emissions were
measured using sampling trains consisting of two Teflon coated 47mm filters (front and back).
See Appendix A for details on EPA Alt-125.
The model Liberty was tested for thermal efficiency and carbon monoxide (CO) emissions in
accordance with CSA B415.1-10 using Douglas Fir cordwood.
SUMMARY OF RESULTS
The weighted average emissions of the three test runs included in the results indicate a
particulate emission rate of 2.50 grams per hour. Particulate emissions used in the weighted
average were sampled on only one of the high burn fuel loads, test 3 and 5 were conducted to
generate a coal bed for test number 4 and 6. Run number 2 was considered invalid due to a fuel
load piece used for the test was outside the acceptable weight range. The Liberty results are
within the emission limit of 2.5 g/h for affected facilities tested with cordwood, manufactured on
or after May 15, 2020.
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.

INDIVIDUAL RUN SUMMARIES
Run 1 - Test procedures followed to produce a high burn rate with a primary air setting of
fully open. Observed burn rate was calculated at 4.61 kg/hr. Emissions results
were calculated using particulate sampling from kindling, start-up fuel, and test
fuel load combined (cold to hot). Burn rate, and efficiency were calculated using
data from the test fuel load only (hot to hot). No sampling anomalies occurred,
this test run was determined to be valid for inclusion in the weighted average.
Run 2 - Test procedures were followed to produce a low burn rate with a primary air
setting of full closed. Observed burn rate was calculated at 1.36 kg/hr. Emissions
and efficiency results were calculated using a hot to hot burn cycle, a coal bed
generated by the high burn conducted in test one was used. Prior to starting run 3
a fire box volume drawing was submitted showing a volume larger than that
calculated by the testing laboratory. After review of the document it was agreed
that the larger volume calculated by a computer drawing program was accurate.
This caused one of the fuel load pieces used in the fuel load to be outside the
acceptable weight range. Due to this, test number 2 was considered invalid and
not used in the weighted average.
Run 3 - Test procedures followed to produce a high burn rate with a primary air setting of
fully open. Observed burn rate was calculated at 4.88 kg/hr. Burn rate was
calculated using data from the test fuel load only (hot to hot). No sampling
occurred during this test, it was conducted to generate a coal bed for test number
4.
Run 4 - Test procedures were followed to produce a medium high burn rate with a
primary air setting of 0.125”(1/8”) open. Observed burn rate was calculated at
1.74 kg/hr. Emissions and efficiency results were calculated using a hot to hot
burn cycle, a coal bed generated by the high burn conducted in test three was
used. No sampling anomalies occurred; this test run was determined to be valid
for inclusion in the weighted average.
Run 5 - Test procedures followed to produce a high burn rate with a primary air setting of
fully open. Observed burn rate was calculated at 5.73 kg/hr. Burn rate was
calculated using data from the test fuel load only (hot to hot). No sampling
occurred during this test; it was conducted to generate a coal bed for test number
6.
Run 6 - Test procedures were followed to produce a low burn rate with a primary air
setting of full closed. Observed burn rate was calculated at 1.18 kg/hr. Emissions
and efficiency results were calculated using a hot to hot burn cycle, a coal bed
generated by the high burn conducted in test one was used. No sampling
anomalies occurred; this test run was determined to be valid for inclusion in the
weighted average.

WOOD HEATER DESCRIPTION
Appliance Manufacturer: Travis Industries, Inc.
Wood Stove Model: Liberty
Type: Freestanding Non-Catalytic Wood Fired Room Heater
WOOD HEATER INFORMATION
Materials of Construction: The unit is constructed primarily of mild steel. The firebox
is lined with fire brick that measures 4.5” x 9.0”. The feed door has a 21.8”x 10.4”glass
panel and 1/2” fiberglass rope gasket.
Air Introduction System: Air is introduced into three different areas of the fire chamber
and is controlled by one sliding control rod. Secondary air is introduced into the rear of
the fire box through the bottom, it is then channeled up into the secondary air tubes
located under the baffle. Air wash air is introduced through an opening in the bottom of
the fire box. It is then channeled up to a manifold across the top of the door, air is
directed down across the glass and into the fire chamber. A lower primary air orifice is
mounted on the firebox floor near the loading door. Air is routed through the bottom of
the firebox and into the lower orifice manifold, it is then directed horizontally into the
coal bed near the front of the combustion chamber.
Combustion Control Mechanisms: Combustion air control mechanism is a sliding rod
with flat plates attached that cover and uncover air inlets when the rod is pushed in or
pulled out.
Combustor: N/A
Internal Baffles: A ceramic1/2” fiber board baffle is mounted near the top of the fire
chamber, a 1” thick 6# density ceramic blanket is placed on top.
Other Features: A 400 CFM room air fan is offered as optional equipment; tested model
had a variable speed control mounted in the power supply cord.
Flue Outlet: The 6” diameter flue outlet is located at the rear of the top of the appliance.
