The sealing cone must form a seal in the sample port to prevent the ingress of
air (which may give a false gas reading). The sealing
cone can be moved along the probe pipe to position
the probe tip.
You can use a piece of heat proof fabric to improve the
seal. To sample gas successfully, the probe tip must
bepositionedinthemaingasow.
