Webstone Hydro-Core User Manual

Thank you for choosing Hydro-Core.
This valve kit was designed to facilitate installation and regular maintenance of your boiler. It was
not designed for installations exposed to subfreezing conditions. Drain valves should remain closed
during normal operation. Do not rely on the drain cap to stop the water from draining. When draining,
always remove drain caps slowly to ensure that no pressure exists.
IMPORTANT: Follow all federal/national, state and local codes when installing or performing work on
systems. All parts are covered by a lifetime warranty against manufacturing defects provided they
are installed by a licensed plumber and operated under normal working conditions. Disassembling
parts other than the unions, strainer and handle will void this warranty. If you have any questions or
comments, please contact us at (800) 225-9529 or visit us on the web - www.webstonevalves.com.
