When there is no demand for hot water over a long period, the pilot can be extinguished
by moving the slide control fully to the left.
When hot water is required again, the pilot must be re-established.
If, during prolonged inactive periods, there is any risk of freezing, the heater should be
drained by firstly isolating the appliance from the incoming cold water supply (close the
water cock). Then open the taps and drain down.
