ONE SUPPLY TAPPING

• All installations shall follow National/Local codes and requirements mentioned in boiler installation manual.• It is recommended to apply Teflon tape or quality pipe dope on all threaded connections.• Engagement depth for all piping is normally around 19/32” per threaded connection.• Engagement depth of threaded connection depends on quality and supplier of parts. Installer is responsible for

making sure each connection is fully engaged, secure, and leak free.• General guide only. Check dimensions of specific install location and adjust piping as needed to meet

requirements in IOM.• This guide is not intended to require replacement of existing piping. Existing piping may meet the requirements

outlined in the IOM.

FOR 3 AND 4 - SECTION BOILERS ONLY
