In our experience, gas valves very rarely need replacing. When they do it is usually due to either the
knob being forced or the thermostat capillary being crushed or twisted off.
When replacing gas valves there are several things to be checked and possibly changed.
Firstly you should check that the low pressure by pass screw is the correct one for the stove and the
type of gas ( L.P.G. Or Nat gas) .This can be found by removing the cover of the gas valve(small x
screw). Obviously if you are replacing like for like, just remove the bypass screw from the original
and put in the new one.

The valve has two inlet ports and two outlet ports, the ports that are not it use have to be blanked
off.
An arrow shows which way the gas flows in and out.

The outlet port with the “bypass hole”.
In the outlet port there is a ”bypass hole” , which if covered by the wrong fitting i.e. With a long
thread, it will cause the valve not to work properly. The symptoms of this are that the manual over
ride will not work and you may find that the fitting leaks. If it is in the port that you are not using use
the aluminium surface blanking plug provided, NOT the brass allan socket plug.
The use of these ports change from stove to stove so you will more than likely have to change them
over. Once the gas valve has bean changed the main burner pressure will have to be checked and
reset.
