FAQs
1. What boilers is the Ravenheat CSI 120 Flow Manifold compatible with?
The flow manifold 0011GRU11005/0 fits Ravenheat CSI and HE Series boilers. This includes CSI 120 Low NOx NG/LPG (up to serial no. 16007132), CSI 120/150 T Low NOx NG/LPG with or without a timer, CSI 150 Low NOx, CSI 85 AAA 780 NG, and HE 120N, HE 120NT, HE 150N, and HE 150NT models. Always check your boiler’s serial number to ensure compatibility.
2. What is the function of this flow manifold?
The flow manifold manages water distribution within the heating system, ensuring even circulation between the boiler, radiators, and hot water circuits. This helps maintain efficient heating and prevents pressure imbalances.
3. How does the manifold help my boiler perform better?
By ensuring balanced water flow, the manifold reduces strain on the boiler, maintains consistent heat distribution, and prevents blockages or uneven heating. This supports overall system efficiency and longevity.
4. Can this manifold be installed on both gas and LPG boilers?
Yes, this part is compatible with NG (natural gas) and LPG (liquefied petroleum gas) Ravenheat boilers, including CSI 120 Low NOx and CSI 120/150 T Low NOx models. Installation should always be carried out by a Gas Safe registered engineer.
5. How do I know if my boiler needs a new flow manifold?
Signs that a flow manifold may need replacement include uneven heating in radiators, low water pressure, boiler cycling on and off frequently, or unusual noises in the heating system. Replacing the manifold helps restore proper water flow and ensures the boiler operates efficiently.
