When replacing, make sure ALL rust in removed on heat exchanger plate. A good Sealant (not silicone!) may need to be used to fill gaps in pitted cast iron after rust removal. Use a sealant such as Permatex Copper found here.
For larger gaps in the heat exchanger steel plate, we recommend filling and sealing with: Ferropre.
When replacing the manifold, you should also buy the Tube Seal Kit. (Comes with 9x new tube seal gaskets which were originally red or black)
