1. Tap the actuating pin with the control knob set at the
highest position. In this way, any slight accumulation of
dirt in the metering stem slit will be removed.

De-Coking using the Allen Key Tool
This operation must only be carried out with the stove TURNED OFF and COLD. The de-coking and inlet
pipe are located behind the lower door and to the right hand or left hand side of the burner pot. Remove the
end cap with the tool supplied with the stove. The tool is then inserted into the inlet pipe rotating it as it is
pushed in towards the burner, until the cardon deposits have been scraped clear of the inlet.
