Gas burner question please. Missing bit???

[Andacami]

Hi All,

Fridge seemed not to work on gas so having a quick look.

Is there a bit missing between the gas union and the burner tube? (I have the cover)?

I have good spark and plenty of gas, oven and hob and heating working.

Ok. No missing bits, gave it good clean with compressed air can and it now ignites and burns.

Also gave the flue a quick sweep.

Will see if the performance is OK over the next couple of days.
