There are two types of valve, which could be fitted to the stove.
Access to the low fire adjustment is different; make sure you know which valve you are
working on.
On the OCI ships valve the plastic drive knob has to be removed to gain access to the low
fire screw.
On the Toby valve the low fire screw is clearly visible as per TOBY MANUAL FIG 2
It is advisable to have a flue vacuum gauge available before carrying out this procedure.
The Toby valve has been flow rated before leaving the factory and it should not need
adjusting, if it does it is necessary to remove the plastic drive cover (OCI VALVE) which is
held in place by a single fastener in the side face of the knob.
Once the knob has been removed the low fire adjusting screw is clearly visible.
When the burner has established good blue flame combustion turn it up to half output.
