23Regulation of combustion airAll stoves are equipped with a one-handed operating lever for regulating the damper.Alternatively, the stove can be equipped with a self-regulating, automatic CleverAIR ™air damper. Regulation of combustion air with the lever is described in the illustrationsat the front of the manual.Primary air is the combustion air that is added to the primary combustion zone, i.e., theglowing embers. This cold air is only used in the lighting stage.Secondary air is the air added to the gas combustion zone, i.e. contributing to thecombustion of pyrolysis gases (preheated air used for glass system and combustion).This air is sucked through the damper behind the combustion chamber and pre-heatedbefore being emitted as hot scavenging air onto the glass. The hot air rinses the glassand keeps it soot-free.Tertiary air on the back of the combustion chamber at the top (rows of holes) ensuresthe combustion of unburned fumes / particles before rising up through the chimney.Pilot nozzles located at the bottom on the back of the combustion chamber ensure thatthe bed of glowing embers is fed with air and, therefore, holds a high temperature.This allows a quick start when fueling and reduces the risk of the fire extinguishing.By setting the interval between position 1 and 2 (see section 'Adjusting the damper')ensures optimum utilisation of the energy content of the wood as there is oxygen forcombustion and burning of the pyrolysis gases. The damper is deemed to be set cor-rectly if flames appear clear yellow. Finding the correct position comes with the regularuse of the stove.We do not recommend closing the damper too early, for example, when you anticipatetemperature rising too high. Insufficient air supply produces poor combustion, whichcan result in high and dangerous flue gas emissions and poor efficiency. As a result,dark smoke will rise up from the chimney, while the wood heating value will be partlywasted.VentilationExtractor fans may not be fitted in the same room as the stove, as this can cause thestove to emit smoke and fumes into the room.The stove requires a permanent and adequate air supply to operate safely and effective-ly. The installer may have fitted a permanent air supply vent into the room in which thestove is installed to provide combustionThis air vent should not be shut off or sealed under any circumstances.Drying and storageWood needs time to dry. Proper air drying takes approximately 2 years.Here are some tips:• Store the wood sawn, split and stacked in an airy, sunny place, which must beprotected against rain (the south side of the house is particularly suitable).• Store the firewood stacks at a hand’s breadth apart, as this ensures that the airflowing through takes the moisture with it.• Avoid covering the firewood stacks with plastic, as this prevents the moisture fromescaping.• It is a good idea to bring the firewood into the house 2-3 days before you need it.English RAIS/attika - User manual for VIVA L
