Brass Hpb57-3 4 Channel Underfloor Heating Manifold With Integrated Underfloor Heating Manifold With Auto Vent Valve

Floor heating  Manifolds installation:
1. Installation of floor heating water distributor: The water inlet and outlet of each loop heating pipe connected to the water inlet and outlet should be connected to the water distributor and the water collector respectively. The inner diameter of the water distributor and water collector should not be less than the inner diameter of the total supply and return pipes, and the maximum cross-sectional flow rate of the water distributor and water collector should not be greater than 0.8m/s. Each water distributor and water collector branch loop should not exceed 8 channels. Too many loops will lead to too dense piping at the sub-collector, which is not conducive to installation. A shut-off valve such as a copper ball valve shall be provided on the supply and return pipes of each branch loop.
2. Installation of floor heating water distributor: corresponding installation valve
On the water supply connection pipeline before the water distributor, valves, filters and drain pipes should be installed in the direction of water flow. Two valves are set before the water separator, mainly for cleaning the filter and closing when replacing or repairing the heat metering device; the filter is set to prevent impurities from clogging the flow meter and heating pipe. The valve and filter before the heat metering device can also be replaced by a filter ball valve. On the return water connection pipe after the water collector, a drain pipe should be installed, and a balance valve or other shut-off adjustment valve should be installed. System accessories should be made of corrosion-resistant materials. Install a drainage device for flushing pipes and drainage before acceptance and after maintenance. It is best to have drainage devices such as floor drains near the drainage device. For systems with heat metering requirements, a heat metering device shall be provided.
3. Bypass: between the main inlet pipe of the water distributor and the main outlet pipe of the water collector, a bypass pipe should be set up, and a valve should be set on the bypass pipe. The connection position of the bypass pipe should be between the beginning of the main water inlet pipe (before the valve) and the end of the main water outlet pipe (after the valve) to ensure that water does not flow into the heating pipe when flushing the heating pipeline system.
4. Installation of floor heating water separator: set manual or automatic exhaust valve.
Install an automatic air release valve as much as possible, so as to bring convenience to users in the future use process, and avoid the gas collection caused by factors such as cold and hot pressure difference and water replenishment, which hinders the operation of the system.
