The descaling device is screwed directly into the vaporising pot and needs to be
dismantled adjusted and cleaned on a regular basis.
When the low fire flow rate is set on a new and clean pot there is no resistance to the
flow of oil.
During normal use carbon will build up around the inner diameter of the descaling device.
This build up will act as a resistor to the flow of oil and the low firing rate will gradually
diminish until there is insufficient oil flow to support low fire, blue flame combustion.
