Abstract This practice sets forth the acceptable installation and service use of solar space heating systems for one- and two-family dwellings to help ensure adequate performance, safety, and consumer satisfaction. This practice, however, does not apply to Rankine cycle, heat pump, or high pressure vapor systems, and is not intended to abridge safety or health requirements. Specifications are provided for the following system components: collector subsystems; thermal storage devices; controls and safety devices; piping, ducting, and ancillary equipment; electrical wiring; and auxiliary (nonsolar) space-heating equipment.Scope 1.1 This practice covers solar space heating systems for one- and two-family dwellings. It sets forth acceptable installation and service practices to help ensure adequate performance, safety, and consumer satisfaction. 1.2 This practice is intended to describe acceptable practices for space heating systems in new and existing dwellings and shall not be construed as the optimization of good practices. 1.3 This practice does not apply to Rankine cycle, heat pump, or high pressure vapor systems. 1.4 This practice is not intended to abridge safety or health requirements. All systems shall be installed in accordance with local codes and ordinances. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (For specific safety precautions, see Section 6). 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
