Water leaking from the bottom of the Brötje furnace casing

Safety: Isolate power and, if necessary, close isolation valves to prevent further leakage. Beware of hot water.

• 1. Remove front cover: Carefully remove the boiler front panel and inspect inside with a torch.
• 2. Identify source: Look for traces of water around the circulation pump, automatic air vent, heat exchanger, and pipe unions.
• 3. Tighten unions: Gently tighten any slightly loose compression or union fittings. Do not overtighten.
• 4. Replace leaking components: If the pump, air vent, or a gasket is leaking, replace the specific Brötje component. If the primary heat exchanger is leaking, it usually requires professional replacement.
• 5. Dry and test: After repair, dry the area, refill and vent the system, then monitor for further leaks.
