GUIDANCE NOTES TUNDISH DISCHARGE The unit is supplied with two mechanical safety devices. An expansion relief valve, supplied loose, and a temperature/pressure relief valve fitted to the unit, both discharging into a tundish (supplied loose). Discharge pipes must be left open to atmosphere, not blocking the tundish. The responsibility for supplying and fitting the discharge pipe from the tundish is that of the certified installer. - Page 5 GUIDANCE NOTES d.3 Discharges at high level; e.g. in to metal hopper and metal down pipe with the end of the discharge pipe clearly visible (tundish visible or not) or onto a roof capable of withstanding high temperature discharges of water and 3m from any plastic guttering systems that would collect such discharges (tundish visible).
