The Combustion System, Explained
This stove uses a three-stage air system for clean, efficient combustion.
① Primary air regulator feeds the base of the fire for quick lighting — close it once the fire is established. ② Secondary air regulator enters above the fire, sustaining the flame and keeping the glass clear. ③ Tertiary air regulator controls the final stage of combustion, directing air to fully burn the remaining flue gases before they exit.
④ The flue damper controls chimney draught — open when lighting or reloading, partially closed to slow the burn. ⑤ The steel reflector and ⑥ vermiculite reflector work together to direct heat back across the firebox rather than letting it escape up the chimney, with the vermiculite layer also helping retain heat after the flames die down. ⑦ Tertiary air enters the firebox at this point, completing the mix that the regulator at ③ controls.
Air Controls: Primary, Secondary, Tertiary
This stove uses three separate controls to manage combustion at each stage.
(A) Primary air — a rotating regulator at the base of the firebox. Turn it clockwise (green) to open for lighting and reloading, or counter-clockwise (red) to close once the fire is established.
(B) Secondary air — a sliding lever above the door. Slide right (green) to open and sustain the flame, or left (red) to close it, reducing airflow and slowing the burn.
(C) Tertiary air — a lever beneath the firebox. Move it toward OPEN (green) to complete combustion by mixing the remaining flue gases, or toward CLOSED (red) to reduce it.
As a general rule: open all three fully when lighting or reloading, then gradually close primary and tertiary air once the fire is established, using secondary air to maintain a steady, visible flame.
Damper Control
The damper regulates draught in the fireplace chimney. When open, it sits parallel to the flue, letting smoke and hot gases draw freely — the correct position for lighting the fire and while it's actively burning. When closed, it rotates across the flue, restricting the opening and slowing the draught.
Partially closing the damper once the fire is established can extend burn time by slowing combustion, but never close it fully while the fireplace is in use, as this can cause smoke to back up into the room.
Prity Mini D Wood Burning Stove – 6.3 kW
Compact by Design. Serious About Heat.
Not every room needs a big stove. Small living rooms, cabins, workshops, and secondary heating spaces need something that heats effectively without dominating the space. The Prity Mini D is built for exactly that — delivering 6.3 kW of radiant warmth from one of the most compact stoves in the Prity range, at just 50 kg.
Class A energy efficiency. Triple air combustion. Over 30 years of Bulgarian engineering. A small stove that does not cut corners on performance.
How Much Space Can It Heat?
The Mini D is suitable for heating spaces of up to approximately 45 m², depending on insulation, ceiling height, and room layout. It works well as the primary heat source for smaller living rooms, cabins, and workshops, and as a practical supplementary heat source in larger homes.
Triple Combustion Technology: More Heat from Every Log
The Mini D uses the same triple air combustion system found across Prity's professional range — a meaningful step up from the single-damper stoves common in this size class.
Primary air ignites the fire quickly and draws the chimney to life. Once combustion is stable, you close it down to prevent overheating and shift into efficient running mode. Secondary air then sustains the burn, feeding the flame through the upper edge of the combustion chamber door and helping keep the heat-resistant ceramic glass clear. Tertiary air completes the combustion cycle, mixing the fuel gases to extract more energy from every log.
The result: 79.0% efficiency and a flue gas temperature of just 249°C — a sign that heat is staying in your room rather than escaping up the chimney.
Class A. EU Certified. Ready for European Winters.
The Mini D carries an Energy Efficiency Class A rating, with an Energy Efficiency Index of 105. It meets the full requirements of EU Ecodesign Regulation 2015/1185, making it fully compliant for installation and use across all EU member states.
Its 69.2% seasonal heating efficiency reflects real-world performance across an entire heating season — not just peak laboratory conditions.
30 Years of European Engineering Behind Every Weld
Prity has been manufacturing solid fuel heating appliances in Gorna Oryahovitsa, Bulgaria since 1995. Every Prity stove is manufactured to BDS EN 13240, the European standard for solid fuel room heaters, and independently verified by TÜV NORD — one of Europe's most respected technical certification authorities.
Your Mini D comes with a 24-month manufacturer's warranty.
