Injector missing from boiler - is it dangerous?

[RenegadeBum]

Hi all,

Turns out our fairly new 40 kW combi, has been running without the injector for months. The gas engineer forgot it when he swapped the gas valve out last year.

So the boiler (Ideal Vogue Max) has been running without one for several months, and also making loud noises. The injector is finally now back in.

From what I understand, the injector regulates gas flow. Should we be concerned health-wise about any harmful gas released, or contamination of the water coming from the boiler?

Thanks

No way will your water be contaminated , and any harmful gas would be going outside but amazed it worked without explosive ignition and making loud bangs it very well may have damaged the burner /electrodes heat exchanger .
If it was same guy refitting injector that forgot it i would be getting someone to do a second opinion on condition of boiler

Has that stopped the loud noises?

Hi and thanks. Now that the injector is back in, it has stopped making the loud noise

My concern is more if there could be any on-going safety issues caused by the months of "misuse" until the injector was put back in, in terms of gases released or quality of the water.

That's something! It was clearlygetting too much gas without the injector, but interesting that it didn't stop firing on the control-stat before the noise, presumably caused by overheating, started.

My concern is more if there could be any on-going safety issues caused by the months of "misuse" until the injector was put back in, in terms of gases released or quality of the water.

I'm just a DIYer, but my guess is if nothing obvious shows up in the coming weeks, it's OK

Assuming it was installed by a Ideal registered installer you have a 12 year manufacturers warranty .
Any problems your covered

not for a fekup he isnt unless it was ideal themselves

Thanks. I'm less worried about repairs...the boiler seems to be working fine anyway now that the injector is back in.

I've been more concerned about safety effects/contamination for householders, from having had the injector out for many months

in what way do you think water could be contaminated as you have previously mentioned
?

Some sort of rupture between the combustion circuit, and the hot water/heating circuit? It was making loud moaning noises until the injector was put back in, that's why i thought something might be breaking

Phone ideal and get them to come and service it.
Will put your mind at rest.

You are overthinking
Search how a combi works, you will realise that is not possible.

Injector is there to provide correct amount of gas for your boiler model
Missing injector means your burner was getting too much gas. I would want the boiler checked by an independent person as an assurance in case the heat exchanger is damaged. Moaning noise was indicative of bad combustion.
Find it hard how a person can carry out a task yet fail to carry out combustion analysis as a concluding test.
Something a novice would don

Just be glad it was a 40, the over gassing would have been greater if a lower output.
