AppendixManifoldsSupply ManifoldFluid FlowCopper and BrassManifoldsManifolds are used to transition fromsupply/return piping to Onix. Manifoldsare usually copper or brass bodies,with brass branches attached tothe sides.Return ManifoldFluid FlowOnix BarbEnd Cap or PlugFactory Supplied ManifoldsA variety of pre-manufactured manifoldoptions are available from WattsRadiant, each specifically designed tomeet or exceed any job specification.Among the various options are:Custom Tubular (Copper and Brass)Custom Tubular Manifolds arecustom fabricated to each projects specifications with anynumber of circuits in diametersfrom 1" to 6".CazzBrassCazzBrass Manifolds are constructedof cast brass and comein either 3 or 4 circuits and coupledirectly to each other to formlarger manifold sets. CazzBrassmanifolds come with the followingoptions: blank, with flowmeters, or with balancing valves.Stainless SteelStainless steel Manifolds areconstructed of tubular stainlesssteel and range from 2 to 12 circuits.Each pair comes with flowmeters, circuit balancing valvesand mounted brackets.CustomCut (copper)CustomCut manifolds are premademanifolds that come with12 or 16 barbs. CustomCut manifoldsare then cut in the field tothe specific circuit number neededfor each zone.Swedged (copper)Swedged manifolds are pre-mademanifolds with 3, 4, or 5 circuits.One end of a Swedged manifoldTypical Copper or Tubular Brass Manifold Pair.is flared so it can directly coupleto another Swedged manifold.For example, a 3- and a 4-branchSwedged manifold can be fieldcoupled to form one 7-branchmanifold assembly.For more information on the variousmanifold options see our RadiantCatalog, or visit us on the Web atwww.wattsradiant.com.Field ConstructedManifoldsSome installers prefer to build theirown manifolds on the jobsite. Coppermanifolds can be made of any sizecopper water pipe tubing. Manifoldsfrom Watts Radiant are made of type Lcopper for standard use, and if requested,type K copper for undergroundexternal applications.Caution:Use only Watts Radiant Parts.Do not use clamps or Onix Barbs notsupplied by Watts Radiant.Mini Ball ValveOnix BarbConnections made with barbs orclamps supplied by other companiesare specifically excluded from anyWatts Radiant warranty coverage.There are three main ways to fieldconstruct a manifold.1. CustomCut Manifolds:Manifold sticks from the factorydesigned to be used with any Onixbarb. Installers can purchase prefabricatedCustomCuts or base branchmanifolds and field solder variouscombinations of barbs and mini-ballvalves as the job demands.page 58Watts Radiant: Onix Installation Manual
