Remove duct plugs and protec- tive bags only at the time of installation. Open ends of installed ducting must be protected with duct plugs, which must be left in place until the valves are installed and adjusted.

However, the vertical ducting sections must be supported so that their weight does not rest on the coupling. Ifbracketscannotbeused,theconnectionmaybesecuredwith8–10mmpoprivets,wherenecessary.
