13. Installation for all feedwater heaters shall be horizontal.
13. 所有给水加热器应卧式安装。

14. The Supplier shall justify to the Purchaser the chosen arrangement.
14. 供方应向购买者证明所选择的设备布置的合理性。

15. Drain pumps, if any, shall be consistent with the general technical requirement of pumps and furthermore with the following specifications.
15. 排水泵（如果有）应符合泵的一般技术要求，以及以下规格要求。

16. The Supplier shall supply for approval to the Purchaser a calculation document for pump design (flow, manometric head, NPSH...) and another document supplying details concerning the suction line behavior from minimum to maximum flow and during transients (with depressurisation taken in account).
16. 供方应向购买者提供泵设计的计算文件（流量、压力计水头、净正吸入压头）以及说明从最低到最高流量过程中以及瞬态过程中吸入管线的特征细节的文件（考虑降压）供购买者审批。

Beijing Chinese Subtitling Translation Service Agency has translated many technical documents about Heater construction requirements.
华译网上海翻译公司曾经翻译过大量有关加热器施工要求资料文件。

17. This calculation shall be made for required NPSH 3% and 0%. In every case available NPSH shall be greater than or equal to 1.
17. 该计算应根据要求的净正吸入压头3%和0%做出。在任何情况下，可用的净正吸入压头都应大于或等于1。

18. Each drain pump shall be designed to sustain without any damage:
18. 每个排水泵应能够无任何损坏的经受以下情况：
