OPERATING TEMPERATURE AND PRESSURE

Watts Radiant Onix Manifolds are manufactured in several styles for

radiant floor heating and snowmelting applications: Custom Tubular,

Swedged, CustomCut™, Stainless Steel, and CazzBrass™. Manifolds

are constructed of either copper, cast brass, or stainless steel as

shown in the schedule below. All brass barbed branches are

constructed of solid brass to accept Onix tubing. Manifolds and

manifold components are assembled by brazing and/or soldering.

Ribbed branches are spaced at 2" on center (o.c.) on all Custom

Tubular Manifolds. Branches on CustomCuts are spaced at either 3"

or 4" o.c. Three inches are allowed on ends of manifolds, including

union if supplied. Stainless Steel Manifolds have a branch spacing

of 2-1/8" o.c., CazzBrass Manifolds have a spacing of 2".

All mani-

folds have a maximum operating pressure of 100 psig at 200°F.

Several options are available as described below.

OPTIONAL MANIFOLD FEATURES

1. Mini Ball Valves (MBVs) are supplied for system purging,

balancing, and isolation. MBVs are made of brass construction with

stainless steel ball and Teflon seats. MBVs are installed on the

return manifold (BVR), or the supply and return manifold (BVSR) of

Custom Tubular Manifolds. Swedged and CustomCut Manifolds are

supplied either with or without MBVs.

2. Unions can be installed on Custom Tubular Manifolds for ease of

installation and system maintenance. 1" all-brass unions are

constructed entirely of solid brass and come with a rubber O-ring to

assure a tight seal. 1-1/4" to 3" unions are constructed of brass

nuts with copper sleeves and an O-ring seal.

3. Vent-and-purge Assemblies or End Assemblies are available for

purging air and/or water from the radiant zone(s). These assemblies

are constructed of a “key” type manual vent and drain valve for

system purging.

4. Other specialized components as described and verified by

manufacturer:________________________________________________
