3.1 Appliance and its constituent parts
3.1.1
overhead luminous radiant heater
gas-fired appliance intended for installation at a height above head level, which is designed to
heat the space beneath by radiation and in which the heat is produced by means of burning the

fuel at or near the outer surface of a material such as a ceramic plaque or gauze, or by means of a
burner heating a gauze or similar material
3.1.2
atmospheric burner
aerated burner in which the air for combustion is entrained at atmospheric pressure
3.1.3
inlet connection
part of the appliance intended to be connected to the gas supply
3.1.4
mechanical joint
means of ensuring the soundness of an assembly of several (generally metallic) parts without the
use of liquids, pastes, tapes, etc
Note 1 to entry: For example the following:
a) metal to metal joints;
b) conical joints;
c) toroidal sealing rings (“O” rings);
d) flat joints.
3.1.5
gas circuit
part of the appliance that conveys or contains the gas between the appliance gas inlet connection
and the burner(s)
3.1.6
restrictor
device with an orifice, which is placed in the gas circuit so as to create a pressure drop and thus
reduce the gas pressure at the burner to a predetermined value for a given supply pressure and
rate
3.1.7
gas rate adjuster
component allowing to set the gas rate of the burner to a predetermined value according to the
supply conditions
Note 1 to entry: Adjustment can be progressive (screw adjuster) or in discrete steps (by changing
restrictors).
Note 2 to entry: The adjusting screw of an adjustable regulator is regarded as a gas rate adjuster.
Note 3 to entry: The action of adjusting this device is called “adjusting the gas rate”.
Note 4 to entry: A factory sealed gas rate adjuster is considered to be non-existent.
Note 5 to entry: Immobilizing a gas rate adjuster by means as e.g. a screw is called “setting an adjuster”.
Note 6 to entry: Arrangement in respect of the adjuster such that any attempt to change the adjustment
breaks the sealing device or sealing material and makes this interference apparent is called “sealing an
adjuster”.

EN 419:2019 (E)
Note 7 to entry: A gas rate adjuster is considered to be non-existent if it has been factory sealed in a
position such that it is not operational in the range of supply pressures corresponding to the appliance
category.
Note 8 to entry: Putting an adjuster or a control (of temperature, pressure, etc.) out of action and sealing
it in this position is called “putting an adjuster or a control out of service”; the appliance functions as if the
adjuster or control had been removed.
