US Stove 5040Ei Pellet Stove Insert Features
- Powerful Supplemental Heating: Delivers up to 40,000 BTUs to comfortably warm spaces up to 1,800 square feet, making it ideal for medium-sized homes, condos, and finished basements.
- Generous 45 lb. Hopper Capacity: Holds enough premium hardwood pellets for up to 40 hours of continuous burn time, dramatically reducing the frequency of refueling during cold snaps.
- Fireplace-Ready Insert Design: Engineered to drop directly into existing masonry or zero-clearance fireplaces, converting an inefficient open hearth into a high-output pellet heater without major remodeling.
- Included Decorative Surround: Ships with a sleek black surround panel that frames the unit cleanly against the fireplace opening for a finished, factory-built look.
- Programmable Digital Control Board: Easy-to-read electronic controls let you adjust heat range, fan speed, and feed rate with the push of a button for precise comfort.
- Remote Control Operation: Adjust settings from across the room via an IR remote that pairs with the sensor on the stove — no wireless smart-thermostat setup required.
- Wired Thermostat Compatible: Supports a hard-wired wall thermostat in High/Low mode, allowing the stove to modulate output based on room temperature for set-it-and-forget-it operation.
- Automatic Ignition System: Built-in igniter starts the fire on demand — no manual lighting, no gel starters, no fuss.
- Clean-Burning Wood Pellet Fuel: Designed and EPA-tested to burn PFI-certified premium hardwood pellets, a renewable biomass fuel that produces minimal ash and low emissions.
- Convection Blower for Even Heat: Integrated blower actively circulates warm air into the living space rather than letting it rise up the chimney like a traditional fireplace.
- Top or Rear Venting Flexibility: Can be vented through an existing chimney or routed through the ceiling, giving installers options for both retrofit and new construction.
- Heavy-Gauge Steel Construction: Built with durable welded steel firebox construction backed by U.S. Stove Company's 150+ years of heating experience and South Pittsburgh, Tennessee engineering.

US Stove 5040Ei Pellet Stove Insert FAQ
What type of pellets should I use in the 5040Ei?
US Stove recommends only PFI-certified premium hardwood pellets. The stove is designed and tested specifically for wood pellets — do not burn corn, coffee pellets, or other alternative biomass fuels, as this can damage the stove and void the warranty.
Can I install the 5040Ei in my existing fireplace?
Yes — this unit is purpose-built as a fireplace insert and includes a decorative surround to frame the opening. It can vent through your existing chimney or, if needed, through the ceiling. Refer to the owner's manual for exact clearance and venting requirements, and US Stove recommends using an NFI Certified Installer for the install.
Does the 5040Ei work with a smart thermostat or Wi-Fi?
The 5040Ei (non-"W" model) works only with hard-wired thermostats and an included IR remote — it does not accept wireless or smart thermostats and does not have Wi-Fi. If you need app/Wi-Fi control, look for the 5040Ei-W variant, which integrates with the USSC App.
Will the stove shut off when my room reaches the set temperature?
No. The 5040Ei uses a High/Low thermostat mode rather than On/Off. When the room is at temperature, the stove drops to heat range 1 (lowest setting) and continues burning; when the thermostat calls for heat, it ramps up to your selected heat range. Because of this, room temperature can occasionally exceed the setpoint.
What happens during a power outage?
Pellet stoves require electricity to run the auger, igniter, and blowers. For short outages, US Stove recommends a minimum 1000-watt pure sine wave inverter battery backup. If using a generator, a 1000W inverter generator is recommended to protect the control board.
Do I need a fresh air kit?
A fresh air kit is required if the stove is mobile-home certified and installed in a mobile home. It is also recommended for newer, tightly built homes, homes with limited makeup air, or any installation experiencing poor combustion. Consult the owner's manual for fresh air intake specifications.
How often does the stove need to be cleaned?
The burn pot should be emptied and cleaned before each ignition, and inspected daily during continuous use. The exhaust pipe, flue, and clean-outs should also be kept free of ash and debris — a dirty system can trigger vacuum issues that cause the auger to stop turning or the stove to shut down.
What's the warranty and where can I find the owner's manual?
The 5040Ei carries US Stove Company's limited manufacturer warranty — full terms are detailed in the owner's manual and on the US Stove warranty page. The 5040Ei Owner's Manual (2025 models or newer) is available as a free PDF download directly from US Stove's website, with installation, operation, and maintenance instructions.
