Advice

The proper installation of a wood appliance is very important to give you maximum performance with minimum consumption and to be sure of the installation and its safety. Here at LACUNZA, it appears essential to us that the installation and periodic maintenance be carried out by an authorised installer in accordance with the specifications of each country’s applicable regulations and our instruction manuals. A few more recommendations include:

  • The straighter the better: The straighter the flue pipe is, the less problems will arise with possible smoke blow-back. In LACUNZA we recommend a maximum elbow of 45º.
  • The connection: The connection between the appliance’s smoke outlet and the main duct must be perfect. Avoid constriction, section changes and also avoid changes of direction. It is important to facilitate the smoke’s path towards the outside without any difficulties. So, in this sense, it’s very important that the connection be completely sealed.
  • Fireplace damper or draught: An independent and unobstructed fireplace is recommended. In addition, it’s very important that the pipe be insulated since this allows the temperature of smoke inside to remain higher and contributes to greater damper or draught.
  • The pipe: When your fireplace, cook stove or wood burning stove is installed, the pipe that sticks out of your rooftop must surpass the ridge cover. There mustn’t be any obstacles preventing the smoke from getting out at the end of its path.
  • Air intake: The appliance requires air (oxygen) for combustion. Without oxygen, there can be no combustion. Its entry must always be ensured through a screen or, if the appliance has built-in conduction, by making the corresponding connection to the outside. This is a very important issue for the appliance to function properly. In addition, if proper air intake is ensured into the premises, it will also translate into a healthier and purer environment for your health.
  • Independent smoke outlets: The stove’s outlet should always be independent and should not connect with other ducts connected to other appliances.
  • Stainless steel flue outlet: It is recommended that it be built in stainless steel, since its antioxidant properties will make it last longer and work properly.
  • Smoke dispersion: To prevent smoke from dispersing, it is advisable to use cap nuts with a proper passage section at the end. The outlet section must be at least twice that of the pipe.
  • Prevent smoke blow-back: To prevent smoke returns at the end of the pipe, there should be no physical element within a minimum radius of 8 m. Also the cap nut must be located at a minimum height of one meter above the ridge, the highest part of the roof.
  • Insulation: Read our instruction manual carefully. Use fireproof insulators and the right materials.
  • The connection between the appliance’s smoke outlet and the main duct must be perfect. Avoid constriction, section changes and also avoid changes of direction. It is important to facilitate the smoke’s path towards the outside without any difficulties. So, in this sense, it’s very important that the connection be completely sealed.

A-L M-Q R-Z
A
AEFECC
AEFECC is the only association that brings together manufacturers, importers and suppliers of wood burning stoves, fireplaces, cook stoves, boilers and, in general, wood burning and biomass appliances in Spain.
Airtight
Combustion occurs within a closed chamber, acquiring the necessary oxygen from the outside without altering the oxygen in the fireplace.
Atmospheric power
Heat transferred to the atmosphere.
Axial fan
This is a type of fan where both the motor and the blades are mounted directly on the shaft. When the shaft and blades rotate, it produces a current parallel to the shaft.
C
CE Power
Average power available from the device, certified in official laboratories.
Centrifugal Turbine
A centrifugal tangential fan in which air is driven by a turbine or impeller, sucking it through the centre, expelling it through its blades parallel to its axis and exiting in a perpendicular direction to achieve greater pressure / speed with less sound.
Cleaning Access
Easy access to remove soot through a hatch (patented) Easy manual disassembly of the baffles, no tools required.
Cleanout door
They are usually cast doors without glass. They are totally opaque.
Closed stove
Completed constructed modular wood burning cook stove ready for installation.
CO emissions

A value that measures emissions of carbon monoxide, an odourless, colourless, tasteless, toxic and highly flammable gas.

Conto Térmico
An Italian regulation that encourages interventions to increase energy efficiency and thermal energy production from renewable sources for small installations.
Convection
It is called convection when heat is transmitted and creates natural air circulation in any room.
D
Damper
Rotating cover that allows the passage of air/smoke through a pipe to be opened/closed
Deflector
A device used to divert the direction of the smoke flow before leaving the duct
Double Combustion
Technology whereby the gas from the firewood’s initial combustion is burned again. It provides greater efficiency and life for your firewood with lower consumption.
Double sided
These are fireplaces or wood burning stoves that have glass on the front and back of the fireplace in order to see the fire and get heat from both sides.
Ducting
Channelling of air through ducts
E
Easy Fire Control
Fire control system that can regulate the optimal combustion and cleaning of the firewood appliance with one simple remote control device.
Easy To Clean
Surface treatment of the wood burning cook stoves with a high-quality enamel. Makes cleaning easy with as little as a damp cloth.
Ecodesign 2022
A European regulation (compliance with which is mandatory starting in 2022) that will require greater energy efficiency in all products and lower emissions of CO, OGC, NOx and other types of hitherto uncontrolled pollutant gases.
Ecolabel
A European certification related to energy consumption. It grades the product based on strict sustainable criteria defined at European level and ensures that the purchased product meets the maximum sustainability requirements
Energy efficiency
This consists in the efficient use of energy. We refer to an efficient wood burning appliance when it consumes less energy than the average energy required to make it work.
Eolo System
High pressure ventilation system with centrifugal turbines and speed regulator (switchboard) to allow different rooms of the home to be heated through ducts.
External Air Inlet
Connectible system that takes air from outside the house for combustion. Suitable for low consumption housing.
Extra Clean Glass
Novel air intake system on the glass to keep it clean for longer.
F
Fan

An instrument or apparatus with rotating blades that drives or removes air.

Flamme Verte
Flamme Verte is a quality label for wood burning appliances in France. To obtain the Flamme Verte label, the energy and environmental performance of each device is controlled in laboratories, accredited against ISO / IEC 17025 and notified by the European Commission, whose tests give access to the CE certification.
