How can I ensure the flame is blue?

[Lucky Luke]

Hi, heating experts. In our living room is a Gas Miser gas fire (5 radiants). When this fire is on, I notice that, at the bottom of the radiants, though the flame is mostly blue, occasional "flashes" of yellow flame leap up. In years gone by, after a long time without cleaning the fire, longer yellow flames would produce smoke that discoloured the radiants (in any case, it was obvious that the burning was not right). Occasionally, I would take out the metal tube (the one that feeds gas to the radiants) and wash it under a tap, which seemed to cure it. However, the metal started to show rust, so I stopped doing this.

What must I do to avoid yellow flames appearing, without rusting the gas-burner tube? I have tried applying a powerful suction-hose to the top of this tube (where the holes are, that emit gas to the radiants), but the yellow "flashes" still tend to appear. I would not want them to become more frequent, or to lick the actual radiants. Is it normal to see yellow flashes of flame, and is there anything else that can be done to ensure a totally clean, blue flame underneath the radiants?

Thanks in advance, for any helpful replies.

Have it serviced

Good idea

Like any other gas appliance, it needs serviced by a GSR once a year to ensure it is working properly.

Fire MUST be serviced every year...

Is it orange, which is just rust particles burning off. A gently tap on the side of the fire will confirm.

And a suck usually leads to a blow

It's yellow.

PLEASE get a qualified RGI in to look at your appliance, you are messing around with an open flued appliance that if not burning properly will pass Carbon Monoxide into the room, what you are doing is very dangerous
