Lochinvar Heat Exchanger Top Plate Assembly

The Lochinvar Heat Exchanger Top Plate Assembly is a genuine replacement part for Lochinvar condensing gas boilers and water heating equipment. It is also called a heat exchanger top plate, hex top plate or boiler top plate assembly. It caps the top of the heat exchanger and holds the components that seal the combustion chamber.

Key Features:

• Lochinvar-engineered replacement for the heat exchanger top plate on supported models
• Supplied as a pre-assembled unit, so you don't have to source each component separately
• Helps keep the heat exchanger sealed and the combustion chamber intact
• Matches the original equipment design for a proper fit
• Offered in several part numbers, each made for a specific model range

Use this assembly when a top plate is worn, corroded, leaking or damaged during heat exchanger service. Choose the variant whose part number matches your unit's model and input rating, as listed in the Lochinvar parts manual for your boiler.
