Legend Valve 807-003 Heat Exchanger

This 30 plate heat exchanger delivers 150M BTU/H capacity for RV heating systems. It transfers thermal energy between fluid circuits without mixing them. The unit suits owners replacing a worn exchanger or adding capacity to an existing hydronic loop. Buyers needing a smaller footprint or lower BTU rating should look elsewhere.

Installation notes and common issues

The exchanger connects via 3/4 inch fittings and mounts in any orientation that allows air purging. Tighten connections to spec without over-torquing the plates. Leaks usually come from debris on gasket surfaces or mismatched pipe thread sealant. Flush the system before first fire to avoid sediment fouling the channels.

Pre-order compatibility checks

Verify your boiler or furnace output matches the 150M BTU/H rating so the exchanger is not a bottleneck. Confirm the existing plumbing uses 3/4 inch connections or plan for adapters. Check that the glycol concentration and system pressure fall within the manufacturer's limits. California Proposition 65 warnings apply to this product.

Questions about this item

How can I verify the heat exchanger is delivering the rated 150M BTU/H after installation?

Monitor the temperature difference between the inlet and outlet fluid streams under full flow; a steady delta matching your system design confirms the 30-plate core is transferring heat at the specified 150M BTU/H capacity.

What components are included with the 807-003 unit and what must be sourced separately?

The box contains the 30-plate heat exchanger body only; you must supply 3/4-inch piping, fittings, gaskets, mounting hardware and any required insulation or control valves for your specific hydronic loop.

Which capacity version should I select for a 300-model application requiring 150M BTU/H?

Choose the 300-model 30-plate unit rated at 150M BTU/H; it is the only version in this series that matches both the model designation and the thermal output your design calls for.
