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”.
---------------------- Page: 10 ----------------------
SIST EN 419:2020
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.

3.1.9
main burner
burner that is intended to ensure the thermal function of the appliance
Note 1 to entry: Main burner is generally called “the burner”

SIST EN 419:2020
EN 419:2019 (E)
3.2.2
programming unit

device which executes the programme reacting to signals from control and safety devices, gives

control commands, controls the start-up sequence, supervises the burner operation and causes

controlled shut-down, and, if necessary, safety shut-down and lock-out

Note 1 to entry: The programming unit follows a predetermined sequence of actions and always

operates in conjunction with a flame detector. Such a sequence of operations involving switching on,

starting up, supervising and switching off the burner is called “programme”.
