   ods pilot burner part

Principle

     The system is made up of thermocouple, ignitor, the injector(burner) assembly and the nozzle assembly and so  on. It is designed to shut off the main burner of the gas appliance, when the oxygen content of the room in which the appliance installed is reduced below a predetermined level, so as to shut off gas ovens to protect user’s health and safty.

 

Normal Operation:

20.9 Percent Oxygen -

The flame touches the tip of the Thermocouple, generating the necessary millivoltage needed to hold the gas valve open.

 

Oxygen Level Drops:

19 Percent Oxygen -

The flame begins to lift off the precision pilot burner. The thermocouple begins to cool.

 

Safety Shutdown:

18 Percent Oxygen - 

The unstable pilot flame goes out, causing the thermocouple to cool.

The thermocouple stops generating the electricity needed to hold the spring loaded solenoid valve open. 

The valve shuts the ventfree gas heater down and cannot be started until the oxygen level in the room returns to normal.
