25. Glossary
Ampere (A): unit of measurement (SI) of electric current intensity.
bar: unit of pressure and equals exactly 100,000 Pa. This pressure value is very
close to that of standard atmospheric pressure.
* cal (calorie): equal to the amount of heat required to increase the temperature
of one gram of water by one degree centigrade.
* Groove: housing for the sealing ring.
* cm (centimetres): unit of measurement.
* CO (carbon monoxide): Lightly flammable, colourless, odourless and very
dangerous gas, due to its toxicity.
* CO2 (carbon dioxide): Gas needed by plants on the one hand for
photosynthesis, and emitted into the atmosphere on the other, contributing to the
greenhouse effect.
* Combustion: a process that releases energy. Combustion is basically a chemical
reaction that requires three things in order to take place: fuel, oxidant and ignition
temperature.
* Oxidant: chemical substance that feeds combustion (essentially oxygen) and is
essential for it to take place.
* Fuel: anything that can undergo combustion, in this case wood.
* Creosote: chemical compound created by combustion. This compound is
sometimes deposited on the glass and flue of an insert fire.
* Circuit breaker: Electromechanical device that protects a given electrical
appliance.
* Energy Efficiency: capacity to generate large quantities of heat with the least
amount of energy possible, causing the least environmental impact and reducing
the energy budget.
* CO Emissions: emission of carbon monoxide gas into the atmosphere.
* CO Emissions (13% O2): carbon monoxide content corrected for 13% of O2.
* Differential Switch: protects people and property against earthing failures,
preventing electric shocks and fires.
* kcal (Kilocalorie): multiple unit of measurement of calories. Equivalent to 1000
calories.
* kW (Kilowatt): Unit of measurement equal to 1000 watts.
* mm (millimetres): unit of measurement.
* mA (milliampere): unit of measurement of electric current.
