Model: 5520 Introduction United States Stove Company of South Pittsburg, TN, contracted with PFS-TECO to perform EPA certification testing on 5520 Pellet-Fired Room Heater. All testing was performed at PFS-TECO’s Portland Laboratory. Testing was performed by Mr. Aaron Kravitz. Notes •...
Project # 19-511 Model: 5520 Test Procedures and Equipment All Sampling and analytical procedures were performed by Aaron Kravitz. All procedures used are directly from ASTM E2779 and ASTM E2515. See the list below for equipment used. See Appendix C submitted with this report for calibration data.
Higher Heating Values efficiency of 68.1% and a CO emission rate of 0.34 g/min. The calculated first hour particulate emission rate was 3.11 g/hr. The United States Stove Company Model 5520 Pellet-Fired Room Heater meets the 2020 PM emission standard of ≤ 2.0 g/hr per CFR 40 part 60, §60.532 (b).
Project # 19-511 Model: 5520 Test Run Narrative Run 1 Run 1 was performed on 8/29/2019 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 68.1%. The train A front filter was changed at 1 hr.
Project # 19-511 Model: 5520 Appliance Description Model(s): 5520 Additional Models Discussion: None 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.

Golden Eagle Owner’s Manual Model 5520 Certified for installations in the USA and Canada U.S. Environmental Protection Agency Certified to comply with 2020 particulate emissions standards. This unit is not intended to be used as a primary source of heat.
Important Information This manual describes the installation and operation of the Golden Eagle, 5520 wood heater. This heater meets the 2020 U.S. Environmental Protection Agency’s crib wood emission limits for wood heaters sold after May 15, 2020. Under specific test conditions this heater has been shown to deliver heat at rates ranging from 8,500 to 37,400 Btu/hr.

Specifications Heating Specifications Fuel Burn Rate* (lowest setting) 1.0 lbs./hr. (0.5 kg/hr) Burn Time (lowest setting) 120 hrs. (approximate) Hopper Capacity 120 lbs. (55kg) * Pellet size may effect the actual rate of fuel feed and burn times. Fuel feed rates may vary by as much as 20%. Use PFI listed fuel for best results.
FLOOR PROTECTION This unit must be installed on a 1/2” thick, non-combustible floor protector with a k-value of 0.42. A 1” thick protector with a k-value of 0.84 is also acceptable. The floor protector should be large enough to extend a minimum of 6”...
VENTING REQUIREMENTS • Install vent at clearances specified by the vent manufacturer. • Do not connect the pellet vent to a vent serving any other appliance or stove. • Do not install a flue damper in the exhaust venting system of this unit. •...
VENT TERMINATION CLEARANCES A. Minimum 4-feet (1.22 m) clearance below or beside any door or window that opens. B. Minimum 1-foot (0.3 m) clearance above any door or window that opens. C. Minimum 3-feet (0.91 m) clearance from any adjacent building.
OUTSIDE AIR SUPPLY (OPTIONAL, UNLESS INSTALLING IN A MOBILE HOME OR AN AIRTIGHT HOME) Depending on your location and home construction, outside air may be necessary for optimal performance. Metal pipe (solid or flexible) must be used for the outside air installation. PVC pipe is NOT approved and should NEVER be used.
Control Panel PANEL CONTROLS The blowers and automatic fuel supply are controlled from a panel on the left side of the appliance. The control panel functions are as follows: A. ON/OFF SWITCH • When pushed the stove will automatically ignite. No other firestarter is necessary.
Operation WARNING: • DO NOT USE CHEMICALS OR FLUIDS TO START THE FIRE - NEVER USE GASOLINE, GASOLINE-TYPE LANTERN FUEL, KEROSENE, CHARCOAL LIGHTER FLUID, OR SIMILAR LIQUIDS TO START OR “FRESHEN UP” A FIRE IN THIS STOVE. KEEP ALL SUCH LIQUIDS WELL AWAY FROM THE STOVE WHILE IT IS IN USE. •...
4. DO NOT use the Fuel Feed button (unless you are priming the auger after running out of pellets). A dangerous condition could result. NOTE: During the first few fires, your stove will emit an odor as the high temperature paint cures or becomes seasoned to the metal.
SHUTDOWN PROCEDURE Turning your stove off is a matter of pressing the “On/Off” control panel switch. The red light will go out. The blowers will continue to operate until internal firebox temperatures have fallen to a preset level. WARNING: Never shut down this unit by unplugging it from the power source. SAFETY FEATURES a.

ON/OFF THERMOSTAT MODE (Ignitor life will be cut down in this mode) USE THIS MODE ONLY IF YOU CONNECT A THERMOSTAT. • In this mode, when the home is warm enough the stove will shut off. The fans will continue to run until the stove cools.
CHECK AND CLEAN THE HOPPER Check the hopper periodically to determine if there is any sawdust or pellets that are sticking to the hopper surface. Clean as needed. DOOR AND GLASS GASKETS Inspect the main door and glass window gaskets periodically. The main door may need to be removed to have frayed, broken, or compacted gaskets replaced by your authorized dealer.
