Pellet stoves and boilers - Questions and Answers

  • The control panel is located on the rear part of the top plate and consists of an LCD display and 6 buttons.
  • The display shows all important information about the current state of the stove.
  • The control panel enables communication with the electronic controller via simple button presses.
  • By pressing the appropriate buttons, you can access different menus for monitoring and adjusting stove operation.
  • The stove can be fully programmed on a daily or weekly basis.
  • An optional WIFI controller is available for additional comfort and maximum fuel savings throughout the heating season.

  • Pellet consumption depends on several factors, mainly the number of operating hours and selected power level.
  • The stove can operate at one of 5 power levels or automatically adjust based on system parameters (water temperature, room temperature, etc.).
  • Pellet consumption varies depending on the power level.
  • For example, a 21 kW stove consumes about 1.6 kg/h at minimum power and up to 4.8 kg/h at maximum power.
  • Exact consumption values can be found in the technical specifications of each stove.

  • The heating value of 1 kg of pellets ranges from 4.6 to 5 kWh/kg, depending on manufacturer and quality.
  • Proper stove operation depends directly on pellet quality.
  • Poor quality pellets reduce efficiency and make it harder to reach the desired temperature.
  • They can cause ignition and combustion issues, harder cleaning, operational errors, and reduce the stove’s lifespan.
  • Pellets must be stored in a dry place.
  • Avoid storing them in bags exposed to weather conditions.
  • Moist pellets lead to poor combustion and can block the auger system.

  • One ton of pellets replaces approximately 3 – 3.5 cubic meters of firewood.

  • No. Any other fuel can disrupt normal operation and shorten the lifespan of the stove.

  • No. It may cause structural damage to the stove and boiler and result in irreversible damage to the unit.

  • Pellet stoves must not be installed without a chimney.
  • They require a chimney with a diameter of 80–120 mm for air stoves and 120–140 mm for central heating stoves and boilers.
  • The chimney draft must be between 12–14 Pa.

  • Electricity is required for stove operation due to electronics, motors, an electric igniter, and in boiler models, a pump.
  • The average electricity consumption is about 100 W per hour.

  • The user can set room temperature, boiler water temperature (for boiler models), and stove power.
  • Once the set temperature is reached, the stove reduces power and enters modulation mode or Stand-By.
  • In modulation mode, the stove operates at minimum power to maintain the flame.
  • In Stand-By mode, the stove shuts down and restarts when the temperature drops.

  • Yes, multiple times during the day.
  • All BLIST stoves support HRONO programming with up to 3 on/off cycles per day.
  • Settings can be configured individually for each day, the entire week, or weekends with a different schedule.
  • An optional WIFI controller allows remote control via a smartphone app.

  • Yes. Cleaning is mandatory and must be performed regularly according to the manufacturer’s instructions.
  • It is recommended to clean the combustion chamber before each start while the stove is cold.
  • Regular maintenance is essential for proper and uninterrupted operation.
  • Maintenance is divided into daily, weekly, as-needed, and annual servicing.
  • Daily cleaning: combustion chamber, ash tray, upper flue chamber and turbulators.
  • Weekly cleaning: flue pipes (with steel brush), ash container and pellet hopper.
  • Cleaning as needed: glass (when cold), pellet hopper and “T” junction.
  • Annual service: performed by authorized service, includes cleaning soot, exhaust motor and checking all components.

  • Condensation may occur.
  • To prevent it, flue pipes and the chimney must be properly insulated.
  • Special attention should be given to sections outside the building where flue gases cool down.

  • At maximum power, operating temperature ranges from 80–160°C for boiler stoves.
  • For air pellet stoves, temperatures range from 170–230°C.
