Description
This 9 loop radiant heat manifold is designed for hydronic radiant floor heating systems using PEX tubing. The manifold assembly includes supply and return trunks, flow meters, balancing valves, shut-off components, air vent, drain valves, and mounting brackets for system installation and loop management.
The manifold body is constructed from stainless steel for corrosion resistance and compatibility with closed-loop heating applications.
This product has a 1-year warranty against manufacturer's defects.

- Drain and flush the system as part of regular hydronic system maintenance when required.
- Use compatible antifreeze solutions if installed in freeze-prone environments.
FAQ and Support
Tips for operation:
Before using your manifold, be sure to release the air in the product by using the air relief valve. This will keep unwanted air out of your water system.
