Gas Work

Gas hob burner has an orange flame


I noticed that my Bosch gas job burner had more orange than blue flames yesterday.

I cleaned everything up and dried and then tested later and it was back to blue.

This morning it has gone orange again on all the burners.

I would be grateful if someone could advise please. Do I need to get gas engineer out to have a look? I've had a carbon monoxide alarm next to it and it hasn't beeped.



Update: thanks for all the answers. What I have noticed over the last week is that the flame is orange first thing in the morning and then it becomes blue over the course of the day!!?

I have cleaned everything even the iron cast plates etc. What could be the cause of that.

It needs servicing
Injectors get blocked by small debris causing yellow flame

It's best to replace those injectors

Blocked Injector or Debris On Burner / Ring Top
If in doubt use a Gas Safe Engineer
