Installation Notes
- Turn off power and gas supply to the heater, shut off the pump, and allow the heater to cool fully before service.
- Relieve system pressure and drain the heater water circuit as needed.
- Clean mating surfaces before installing new gaskets/O-rings; replace any damaged sealing surfaces.

Maintenance Tips
- Maintain balanced water chemistry to reduce scale and corrosion that can shorten heater component life.
- Address low-flow conditions early (dirty filter, clogged baskets, closed valves) to reduce stress on internal heater parts.
- If you see repeated manifold seepage, inspect for freeze damage or misalignment in plumbing that may be stressing the heater connections.
