does anyone know anything about gas fires? the one in my living room will only work on 1 or 2 (the middle two bars). if you put it on 3 or 4 the whole thing goes out :-( any ideas anyone

 

 

cheers :-)

could be blocked, and need a clean?

needs cleaning, there is some sooting on the bars which isnt a good thing, possible shimney blockage

i guess it hasn't been serviced for a matter of years/decades lol?

there is 2 jets on the burner, one for the 2 middle and the other for the 2 outers you'll find that jet is blocked

hi guys, and cheers for all the replies. after taking the front off the fire, i found this

 

 

the piece circled in green is a little jet which directs a small flame onto the thermo switch which keeps the gas flowing when hot and also ignites the main jets. this stays on on 1 2 and 3 settings, but it goes out when you turn the dial to 4, so inevitably the switch cools down and cuts the supply. any ideas?? cheers in advance

Here is a bit of info on what is going on with your fire, it could well be the exact issue is the fire is shutting down for safety reasons as there is a fault.

 

Do not attempt to repair your gas fire yourself.

 

 

ODS stands for “Oxygen Depletion Sensor" a term which accurately describes this valve type. The valve itself is similar in many ways to the two valve types above...with one exception. The pilot tube is a precision mechanism that creates a very stable flame as long as the room air contains the proper amount of oxygen. If the oxygen level in the room air drops even slightly, the pilot becomes unstable and lifts off of the thermocouple (see diagram) causing the gas valve and appliance to cease operation. This type of valve is very reliable, and there have been very few failures of this system - even with tens of millions in use worldwide.

 

Normal Operation:

20.9 Percent Oxygen - The flame touches the tip of the Thermocouple, generating the necessary millivoltage needed to hold the gas valve open.

 

Oxygen Level Drops:

19 Percent Oxygen - The flame begins to lift off the precision Pilot Burner. The Thermocouple begins to cool.

 

Safety Shutdown:

18 Percent Oxygen - The unstable pilot flame goes out, causing the Thermocouple to cool. The Thermocouple stops generating the electricity needed to hold the spring loaded solenoid valve open. The valve shuts the ventfree gas heater down and cannot be started until the oxygen level in the room returns to normal

 

 

Given that it is illegal to work on any gas appliance unless qualified its simply not worth the risk to life for an unqualified person to attempt any repair on your fire.

 

Do not attempt to repair your gas fire yourself.

 

Call in an appropriate registered gas safe engineer, follow the link below for more information on this and where to find a local engineer.

 

My advise is watch the video in the link...very powerful message.

That's spot on jeff. Do not use this fire again and get it checked by a gas safe registered engineer. Fires can and do kill :no::angel:

Cheers for your advice jeff what a star! and cheers to everyone else
