The glossary below will help you become acquainted with some of the aspects of our gas heater components.





PIEZOELECTRIC IGNITER

By pressing the manual button a force is applied to a small metallic hammer which hits a quartz cartridge that transmits a discharge to the high voltage electrode outlet. This discharge ignites the gas.

ATMOSPHERE ANALYSER

It is a control device that reacts to the lowering of the amount of oxygen in the atmosphere of a room with an insufficient air change. It consists of: .  pilot burner .  thermocouple .  electrode assembled on a fixing bracket. The thermocouple is a thermoelectric element which is sensitive to the temperature of the pilot burner flame. In normal conditions the flame generates an electromotive force to feed the magnetic unit of the safety valve, allowing gas to flow into the burner. If the amount of oxygen lowers, combustion is no longer optimal. In this case the pilot burner flame modifies itself and the generated electromotive force is no longer sufficient to feed the magnetic unit, so the safety valve shuts off the flow of gas to the burner putting the appliance into safety mode.

LPG CYLINDER

Metallic cylinder containing combustible LPG. 

BLUE-FLAME BURNER

Bored metal burner which emits a blue coloured flame, as a result of the combustion between gas and air.

CATALYTIC PANEL

Catalytic combustion is a chemical reaction activated through a catalyser, the characteristics of which remain unchanged over time. The reaction occurs between the feed gas which flows inside the burner and the oxygen of the surrounding atmosphere. This form of combustion produces no flame.

INFRARED BURNER

It generally consists of a metal chamber which receives a mix of gas and air. The radiating element made of porous ceramic material is placed on the surface of the chamber: the mix crosses the pores of the material to burn on the surface generating heat.

CATALYSER

A system which permits catalytic combustion, or rather activates the chemical reaction between the gas emitted into the panel and the oxygen present in the surrounding environment generating exothermic energy under the form of flameless radiating heat.

CLAMP

Steel device which when tightened provides a good seal to the rubber hose. 

IGNITION WIRE

Glass fibre wire which connects the piezoelectric button and the igniting device.

LIQUIFIED PETROLEUM GAS (LPG)

LPG is composed of mixes of gaseous hydrocarbons at ambient temperature, usually propane and butane. This feature permits storage of large quantities in metal recipients which are easy to manage (cylinders and “tanks”), allowing its wide use as primarily domestic fuel, but also for traction and small/medium scale production activities. Originally, LPG is odourless, but it is odorized with Ethanethiol so that any leaks can be smelt, even without tools.

NATURAL GAS (NG)

Primary source of energy, mainly of fossil origin. Natural gas is a combustible mix of gaseous substances (of hydrocarbons and non-hydrocarbons) extracted from a reservoir rock. The gases belonging to the hydrocarbon family are methane, ethane, propane and butane.

METHANE GAS

Methane is the principal component of natural gas, and an excellent fuel as it produces the largest quantity of heat per unit mass. Methane is odourless, colourless and tasteless, so to be distributed in domestic networks it must be “odorised” by the lapping of a liquid with a characteristic “gas odour”. This procedure is essential so that the presence of gas can be detected in the room and decrease its danger.

CERAMIC TILE

A ceramic structure with external through holes, used as a radiating surface in infrared ray burners. The main characteristic of the ceramic tile is a very low coefficient of thermal expansion and an excellent resistance to thermal shocks.

RUBBER HOLDER

Provides the connection between tap and rubber hose.

METHANE FITTING

Provides the connection between heater and methane gas network.

PRESSURE REGULATOR

A device which works on a fluid (liquid or gas) to provide the required pressure (within the limits of the operation expected) at the outlet.

CONVECTION HEATING

The heat perceived in warm air is convective heating, the heating principal on which convection heaters are based (essentially, it is heating through hot air).

RADIATING HEAT

The heat perceived exposing oneself to a heat source is radiating heat, the heating principal on which radiating heaters are based. This system requires the use of special burners called “infrared rays”.

VALVED TAP

It serves to regulate the flow of gas into the different positions set and to interrupt the passage of gas in case the flame accidentally switches off (safety system). It consists of an attachment for the entry of gas, attachments for where the gas exits for the connection with the burner, an attachment for the thermocouple for the safety system and a rod where the button is located to regulate the different possible positions.

RUBBER HOSE FOR LPG

Rubber hose to connect the heater to the cylinder passing through the pressure regulator. Homologated to UNI CIG 7140, it must be periodically replaced on the basis of the expiry date shown.

STAINLESS STEEL TUBE FOR METHANE

Flexible stainless steel tube to connect the heater to the methane gas network. It must be homologated to UNI CIG 9891.

NOZZLE

A calibrated device which determines the quantity of gas emitted into the burner and, consequently, the heating power of the burner itself.

TANGENTIAL FAN

The tangential fan is a rotating device which moves air. The fan is essentially composed of an electric motor and a rotating propeller to which it transmits energy. The propeller is shaped like an impeller with aluminium blades.
