extension is properly done avoiding the sensing distortion and that the joint is properly insulated to avoid any
electrical failure.
N O T E
When tting the thermistors, remember that they must be secured correctly by the special clamp, ensuring
the perfect contact between the pipe and thermistor. Cover it completely with insulation, like cork tape or pipe
