范围1。1适用性本标准适用于输入功率不超过400000 Btu/h（117 228 W）的转换燃烧器的安装，其设计经认证符合家用燃气转换燃烧器标准ANSI Z21。17.本标准与当地规范或国家燃气规范ANSI Z223（如果没有当地规范）结合使用。1适用于使用转换燃烧器将设备转换为气体的情况，前提是可以根据第2部分和第3部分证明这种转换可以安全、经济且符合消费者的最佳利益。 除非另有规定，本标准中提及的所有“psi”均应视为表压。附件包含本标准中具体引用的标准列表，以及这些参考标准的来源。1.2安全和令人满意的操作一旦决定将设备从另一种燃料转换为气体，安全和令人满意的操作将取决于许多因素。其中包括:（a）适当分析转换的可行性；（b） 正确选择要使用的燃烧器； （c） 正确选择要使用的通风罩或气压通风调节器；（d） 遵循本标准中包含的说明；以及（e）遵循转换燃烧器提供的安装说明。如需更多信息或帮助，请联系设备制造商。在任何情况下，设备的修改不得超出设备制造商的建议。如果无法联系制造商，应咨询当地气体供应商。1.3安装安全和令人满意的安装由确定燃烧器可行性和选择的机构、安装人员和有管辖权的地方当局共同负责。 在许多地区需要许可证。获得该许可证是安装人员的责任。维护和报告可能的不当操作是用户的责任。安装人员有责任告知用户正确的操作和维护。

Scope1.1 ApplicabilityThis standard applies to the installation of a conversion burner with an input of 400,000 Btu per hour (117 228 W) or less and design certified as complying with the Standard for Domestic Gas Conversion Burners, ANSI Z21.17.This standard, in conjunction with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1, is applicable to situations where an appliance is to be converted to gas with a conversion burner, provided it can be demonstrated under Parts 2 and 3 that such a conversion can be made with safety, economy and in the best interest of the consumer.All references to "psi" throughout this standard are to be considered gage pressure, unless otherwise specified.Exhibit contains a list of standards specifically referenced in this standard, and sources from which these reference standards may be obtained.1.2 Safe and Satisfactory OperationOnce the decision has been made to convert an appliance from another fuel to gas, safe and satisfactory operation will be dependent on a number of factors. Among these are: (a) Proper analysis of the feasibility of conversion; (b) Proper selection of the burner to be used; (c) Proper selection of the draft hood or barometric draft regulator to be used; (d) Following the instructions contained in this standard; and (e) Following the installation instructions provided with the conversion burner.For further information or assistance, the appliance manufacturer should be contacted. In no case should the appliance be modified beyond the recommendation of the appliance manufacturer. If the manufacturer cannot be contacted, the local gas supplier should be consulted.1.3 InstallationThe responsibility for a safe and satisfactory installation is shared by the agency determining the feasibility and selection of the burner, the installer, and the local authority having jurisdiction. In many areas a permit is required. Obtaining this permit is the responsibility of the installer. Maintenance and reporting of possible improper operation is the responsibility of the user. It is the responsibility of the installer to inform the user of the correct operation and maintenance.
