Water leaking from the bottom of the Kospel furnace or from internal components.

Safety: Turn off power. If leak is significant, close isolation valves to the furnace and protect surrounding areas from water damage.

• Identify source: Remove the front panel and use a flashlight to trace the leak. Check around the primary heat exchanger, pump unions, and valves.
• Tighten fittings: Carefully tighten accessible union nuts and compression fittings, but do not overtighten.
• Check relief valve: If water is discharging from the safety relief valve outlet, system pressure may be too high or the expansion vessel may be faulty.
• Dry and monitor: Dry the area and monitor for further leakage.

Leaks from the heat exchanger or safety devices should be addressed by a Kospel service technician; component replacement may be required.
