WARNING: Plumbing should conform to proper plumbing methods, and in conformance with local codes or regulations. A licensed plumber familiar with local codes and ordinances should install the OM-180. CAUTION: An ANSI (AMERICAN NATIONAL STANDARD INSTITUTE) listed temperature and pressure relief valve should be installed at the hot water outlet connection of the heater at the time of installation. - Page 9 Install heat insulation material on the hot water piping to prevent heat loss. In closed systems we recommend the use of an antifreege solution to prevent freezing and corrosion. Check with the plumbing installer for the proper mix. Copper or stainless steel or cross-linked polyethylene pipe should be used for the main and branch pipes. Be sure to connect a hot water pipe with the Expansion Tank, and install at the inlet side of the Circulation Pump.
