Introduction
Hearth & Home Technologies of Halifax, PA contracted with PFS-TECO to perform EPA
certification testing on the model Expedition-I Wood-Fired Room Heater. All testing was
performed at PFS-TECO’s Portland Laboratory in Clackamas, OR.All testing was
performed by Sebastian Button.
Notes
•Prior to start of testing, 50 hours of conditioning was performed by the
manufacturer in accordance with ASTM E2780.
•Prior to start of testing, the dilution tunnel was cleaned with a steel brush.
•A 1st hour emissions sample train was pulled for all test runs.
•The blower assembly on this appliance is integral to the design and not provided
optionally, therefore no fan confirmation test was performed.
•A total of 2 test runs were completed. Test runs were performed in accordance
with ASTM E2780 for a single burn rate appliance. See the Run Narrative section
for further detail on each run.

Test Run Narrative
Run 1
Run 1 was performed on 5/13/2021, in accordance with the procedures specified in ASTM
E2780 for a single burn rate appliance. The total test time was 94 minutes. The particulate
emissions rate for the test was 1.64 g/hr, the burn rate was 2.29 kg/hr with an HHV
efficiency of 64.3%. The Train A sample assembly was changed at 1 hr to determine 1st
hour emissions. All test results were appropriate and valid. There were no anomalies and
all test criteria were met.
Run 2
Run 2 was performed on 5/13/2021, in accordance with the procedures specified in ASTM
E2780 for a single burn rate appliance. The total test time was 112 minutes. The
particulate emissions rate for the test was 2.12 g/hr, the burn rate was 1.99 kg/hr with an
HHV efficiency of 64.9. The Train A sample assembly was changed at 1 hr to determine
1st hour emissions. All test results were appropriate and valid. There were no anomalies
and all test criteria were met.
The average burn rate for the two test runs is 2.14 kg/hr, with each test run differing from
the average by 7.0%, which meets the requirement for single burn heaters in ASTM E2780
X1.4.2.

Appliance Description
Model(s): Expedition-I
Appliance Type: Single Burn Rate Wood-Fired Room Heater
Additional Models: This model series is also offered under the Vermont Casting Branding
as the Gifford-CB and Gifford-BM. These models 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.
Firebox Volume: 1.45 ft3
Air Introduction System: Primary and secondary air enter the appliance through fixed
openings on either side of the bottom of the appliance. The primary air is channeled
towards the front of the firebox and down to an air wash over the loading door, while the
secondary air is channeled up the sides and is orificed into a series of 3 stainless steel
secondary air tubes. Start-up air is activated by the Automatic Combustion Control
(ACC), which is meant to be activated during fuel loading. A gated orifice allows air to
enter the front air channel in the bottom of the firebox, through two orifices directed at the
coal bed. The ACC is controlled by a timer mechanism which slowly closes off the air
supply.
Baffles: The secondary air tubes are covered by a ceramic baffle board, which is insulated
by a ceramic fiber blanket.
Refractory Insulation: The firebox is lined with 1.25” thick firebrick.
Flue Outlet: 6-inch exhaust outlet located on the top of the appliance.
Catalytic Combustor: N/A
Fan: The Expedition-I is equipped with a convection fan attached to the lower front of the
appliance.

Test Fuel Properties
Test fuel used was dimensional Douglas fir lumber in 2” x 4” (nominal). Test fuel was air
dried to the specified moisture range of 19-25% dry basis. A typical fuel load is pictured
below:

Sampling Locations and Descriptions
Sample ports are located 16.5 feet downstream from any disturbances and 1 foot
upstream from any disturbances. Flow rate traverse data was collected 12 feet
downstream from any disturbances and 5.5 feet upstream from any disturbances. (See
below).
Sample Points

Project # 21-661 Model: Expedition-I
Page | 16
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 and no sampling intervals fell outside of proportional rates of +/-
10%.
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. 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: 352
Mountain House Road, Halifax, PA 17032, for archival.
