Applications

Commonly used in commercial heating, cooling and

snow-ice melting applications, Viega

valved copper

manifolds are available in 2" and 1-½". They are

available with shut-off valves or shut-off balancing

valves, and are made out of Type "L" copper. Viega's

copper manifolds are copper (male) headers that are

designed to utilize Viega’s ProPress

ttings on the

header inlet and outlet to connect to primary loop

(boiler loop).

Product Instructions Copper Manifold - Valved Applications Commonly used in commercial heating, cooling and snow-ice melting applications, Viega® valved copper manifolds are available in 2" and 1-½". They are available with shut-off valves or shut-off balancing valves, and are made out of Type "L" copper. Viega's copper manifolds are copper (male) headers that are designed to utilize Viega’s ProPress® fittings on the header inlet and outlet to connect to primary loop (boiler loop).
PAGE 2
Product Instructions Installation 1. Viega's copper manifolds are copper (male) on the inlet and outlet of the header, which can be connected to the primary loop (boiler loop) with ProPress or soldered connections. The length of the header is in accordance with ProPress insertion depths and ProPress minimum clearance to existing solder connection. Copper manifolds should be installed using isolation (ball valves) valves on the supply and return headers.

Product Instructions Purging and Pressurization 1. Open the supply and return isolation valve (ball valve) and all supply and return circuits to fill the copper manifold from the heat source (n/a for valveless manifolds). 2. Connect drain hose (i.e. washing machine hose) to hose thread on the return manifold copper end cap purge valve (draw-off). 3. Open purge valve (draw-off) 4. Close supply isolation valve and leave the return isolation valve open. Purge the return line. 5.

Product Instructions Balancing Circuits It is important to balance the circuits on the manifolds to ensure even distribution of the radiant heating. The fluid (water and glycol mix) flows in the path of least resistance. Longer circuit lengths causes higher pressure drops (resistance). The shut-off / balancing valves can equalize the pressure drop (resistance) in every circuit. For proper balancing see calculations and diagrams below.
