Abstract (en)

The heating apparatus comprises a burner (10) and a control device (25) for controlling the gas supply to the burner. During the heating period the burner is alternately lit and extinguished at intervals determined by the control and which may be in response to separately sensed temperature values. The burner (10) comprises a main venturi tube (11) leading to the burner head (12) having a mixing chamber (17) and ports (15) for creating the burner main flames. Within the burner head there is provided an additional mixing chamber (49) communicating with at least one port (48) for creating a pilot flame. The mixing chamber (49) is separately supplied with gas via an additional venturi tube (52). The pilot flame remains lit continuously irrespective of whether the main burner flame is lit or extinguished. The pilot gas supply is manually controlled by the gas cock (22) with a security valve (45) being operated by the thermocouple (46) positioned to be heated by the pilot flame.
