美国“美国人”轻型商用燃气热水器（无节气阀）

• 内胆3年有限质量保证
  　　内胆由超厚钢板通过自动化控制设备滚轧、成型、焊接而成，确保在涂敷烘烤熔融蓝钴陶瓷工艺过程中内胆不会出现缝隙。每个内胆都经过双重质量检验以确保质量合格。
• 配件1年有限质量保证
• 2英寸无氟泡沫保温材料
  　　泡沫隔离保温层通过阻止热量的流失，达到节约能源的目的。
• Fused Ceramic Shield^TM（熔融陶瓷）内胆
  　　钴是一种具有抗磨蚀及抗高温特性的金属元素。美国“美国人”公司把熔融的蓝钴陶瓷均匀地涂敷在内胆上，经过871摄氏度超高温下煅烧烘烤，使得蓝钴陶瓷与内胆熔融成一个整体。这种内胆特别坚固耐用，不易脱落，不易破碎，不易结垢，而且耐腐蚀性能特别强。在正常的使用环境下，这种内胆具有很长的使用寿命。
• 阳极棒
  　　强力阳极棒安装在热水器顶部，有利于强化内胆保护，延长内胆使用寿命。
• 工厂安装的降温减压安全阀
• 水温恢复效率
  　　第一个小时所提供的热量以80%的热效率为基础。热水器面板上的标注的水温恢复指数是75%，符合（AGA）ANSI Z21.10标准的要求。
• 符合的质量标准
  　　通过美国煤气协会和加拿大燃气协会的认证，作为温度达82^oC的（CG32-100T88-4N）和CG32-75T75自动容积式热水器符合AGA ANSI Z-21.10.3标准的要求。50加仑型号的热水器获得认证符合ANSI Z-21.10.1标准的要求。
• 加利福尼亚州（CEC）和纽约州
  　　节能指标符合或优于有关规定的要求。
• 建筑商组合概念
  　　将相同大小的几个热水器组合在一起，作为一个大型热水器系统使用。这个观念使得我们能够可以在不关闭整个系统的状态下进行维护和保养。

　　商用燃气热水器品牌为American® 型号为__________________，由美国“美国人”热水器公司制造，适用的可燃气体为__________________，并获得美国燃气协会（AGA），加拿大燃气协会（CGA）的供热能力达82^oC水温的商用热水器安全认证，满足或者优于所有现行的节能标准。所要订购的热水器容积为________加仑，最小输入热值为________ Rtuh，水温恢复效率为________ GPH（以水温升高______^oC为标准）。热水器的钢内胆在流体静力环境下已经通过300 PSI试验压力检验和150 PSI工作压力检验，采用的Fused Ceramic Shield^TM内胆经过871^oC高温高压下制造而成，能够最有效地保护内胆。CG32-100T88-4N热水器应该提供全尺寸4英寸直径的锅炉式观察清洗口。所订购的热水器应该提供通过AGA和CGA认证的、工厂安装的过热超压安全阀，以及提供阴极保护的阳极棒。热水器外壳应该使珐琅釉面。内胆应该由通过EPA认证的无氟泡沫保温材料包裹隔离。所订购的热水器必须是在美国国内制造，并且具有书面的3年防腐的内胆有限质量保证。随产品应该附有完整的使用、安装和维护说明书。

LIGHT-DUTY COMMERCIAL GAS NON-DAMPERED WATER HEATER

• 3-Year Limited Warranty* on Tank
  Heavy-gauge steel is automatically formed, rolled and welded to assure a continuous seam for glass lining. Each tank is double tested to ensure quality.
• 1-Year Limited Warranty* on Parts
• 2" of Polyurethane Foam - Non-CFC
  Foam insulation saves fuel by retarding heat loss.
• Fused Ceramic Shield^TM
  Applied under pressure and fired at 1600^oF to completely cover the tank interior. This provides a tough interior surface for storage tanks and maximum protection against the wearing effects of high-volume and high-temperature hot water.
• Anode Rod
  Promotes longer tank life through even distribution for protection against corrosion of tank interior.
• Factory-Installed Temperature and Pressure Relief Valve
• Recoveries
  First-hour delivery ratings are based on thermal efficiencies of 80%. Recovery figures shown on water heater ratings plates are based on (75%) recovery efficiency in compliance with (AGA) ANSI Z-21.10 requirements.
• Design Certified
  By the American Gas Association and Canadian Gas Association for up to 180^oF as an automatic storage heater in compliance with AGA ANSI Z-21.10.3 test requirements (CG32-100T88-4N) and CG32-75T75. 50 gallon model is certified in compliance with ANSI-Z21.10.1
• California (CEC) and New York
  Energy requirements met or exceeded.
• Builder Block Concept
  Enables multiple heaters of equal size and input manifolded together to operate as one total system. This concept allows the system to be maintained and serviced without shutting down the complete system.
