Brass Warmafloor Underfloor Heating Manifold with Two Auto Drain Valve

Made of strong stainless steel (CRES 4301)
Open manifold for low temperature systems
Manifold consists of loose components
Open modular manifolds are used where the water supply temperature to the manifold is provided at the correct temperature for the underfloor heating system and a pump elsewhere in the heating system provides enough pressure for sufficient circulation (e.g. the pump of a boiler).
This stainless steel manifold features flow meters which allows you to manually set the flow of water for each port and integrated manual adjustment valves on the return rail (which are set up to take electrothermic actuators).
The open stainless steel can be assembled for high temperature heating systems by means of a Water Temperature Control Unit (or Blending Valve).
Please Note
Euroconus Connectors are not included. Please select the right amount (two per port) and add to your order.



When fixing a manifold to timber studding or plaster board walls, it is recommended that fixing timber

is placed within the timber wall construction where the manifold fixing points are to be drilled and screwed.
this will ensure a secure fix for the manifold. Where this is not possible, suitable cavity fixings can be used.


Step 1 - Fix the manifold onto the wall using the fixing holes on the bracket and the plugs / screws provided.
It must be 650mm from the top of the EPS floor insulation to the top header and level.

Step 2 - Connect the 1" isolation valves to the top and bottom headers(same end) of the manifold.
To avoid leaks ensure that the fibre washers provided are positioned between the valve face and
the manifold prior to tightening the union nut.

Step 3 - The pipe retaining rail should be fixed approximately 175mm below the manifold and should be
trimmed to suit the size of the manifold. It is recommended that +150mm is added to the length of the
manifold. It is recommended that +150mm is added to the length of the rail over the length of the manifold.


Step 4 - Place the fixing lugs onto the rail, push them tight against either side of the pipe (now protected by the corrugated sleeve) and screw them tight, once in position.
