What Is The Function Of This Knob

[irnbru]

Ok so our gas fire keeps going off and it actually banged out once.
I remember having a wee fouter with this knob once before but I dont really know what its meant to do so rather than have another fouter I thought I should ask what its for.
Could it be linked to our fire going off all the time?
ps. Our cooker works fine
Its the knob to the left off the yellow thing.

I don't think it's a knob! I think it's the outlet for an engineer to attach his equipment to in order to test the regulator.

 

[Mr B]

I'm sure it's the thing that the service engineer connects his gadget to ....

 

[Gellyneck]

Also believe it's a connection for the engineer to check system pressure integrity.

The knob slackens and tightens.
So should I go and move it again or will it make no difference to my fire keep going off. Its as if its being starved of gas I think.

Just leave it screwed up ... sounds like your gas fire needs a service ... hope you have a Carbon Monoxide detector!

Sandra, knobs are best left alone.

19 minutes before a "suspect" post. We're slipping gang!!

Good advice though

 

[andy63]

if it is a test point for a pressure/leak test on the system then just make sure its shut, check for any leaks with a little soapy water if you haven't got any leak detector fluid... we know it was ahut at the last meet because we checked for leaks..
sounds like the fault is most probably at the gas valve on fire if everything else works when fire shuts down..just check that's the case..

Sandra make sure it's tight as others have said it's for testing / pressuring the system for gas leaks -

Play with them to much and they might leak.

Or fall off.

Oh jesus, I just went out to see if I could see my problem, turned the knob and the fire isnt going off but I will turn the knob tightvagain and get the fire looked at as advised. I suppose it could be the wind but its not that windy.

 

[Puddleduck]

Yes, get it seen to Sandra. Sooner rather than later.

Normal service is now resumed!

Now heres the weird thing. Ive moved the knob again and the fire is still working.
Strange happenings here, but its least it went again

For one awful moment I thought you were starting a party political thread.

 

[dave newell]

The "knob" in your photo is a cap on the test point, behind it is a non return valve. It is possible that the non return valve has got some dirt in it and is not sealing but when the cap is tight it will seal and hold back the working pressure of 30Mbar (around a half psi). If the valve itself is not sealing then loosening the cap will allow pressure to bleed of at the reg and cause low pressure to your fire and other appliances, when its tight they get full pressure. Hope this helps to clarify some details.

Sandra, stoap foutering! You've got the Falkirk Wheelie mob to control - don't want you having an accident.

recently had to replace the gas regulator ( secumotion type ) ..... the symptoms were gas appliance would run at low flame but when an increase in demand was made ( turn flame up or turn heater control up ) the gas was cut off by the regulator.
changed regulator... all well.

 

[irnbru]

Ok so there seems to be no pattern to this, fire going off and on again, sometimes lasts a few minutes and others more like seconds.
Any ideas? It is a new regulator so shouldnt be that ..i guess.

 

[Phill D]

is it just affecting the fire and not any other appliance? if so it sounds like it " could be" the fire thermo couple that signals the gas valve that its alite

 

[Bailey58]

Yeah I thought someone was asking about Milliband again.

 

[irnbru]

We are going for a record here. Its lasted 12 mins so far and still going

Is it windy where you are? Is the flue partially blocked \ being impacted by the wind?

 

[tonka]

Carol is quiet right,,, !!!!
They are like hand grenades... You don't want one going off in your hand.. !!!!!!

 

[big bertha]

Sandra stop foutering or you'll make yourself fair ferfochin.

 

[irnbru]

I

Its not that windy but I get the full blast from the fields and the fire is facing towards the field. Too much of a slope to face the other way,besides im only outside the house., having withdrawal symptoms of not being away this weekend ;-)

Haha, that ferfochin must be an East coast word, had to google it lol
