Shut Down (see fig. 2)
When hot water is no longer required, the burner will extinguish. The fan may continue to
run for a short period to dissipate the residual heat from the appliance.
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.
