Weil-McLain 633-500-014 Magnesium Anode Replacement Kit for Aqua-Plus 35-85 is a factory replacement anode kit for designated Aqua-Plus indirect water heaters, used to help protect the tank from internal corrosion and extend service life.
Key Features:
- OEM Weil-McLain magnesium anode replacement kit for Aqua-Plus 35-85 models
- Includes replacement anode rod, O-ring, insulating washer, and brass bushing
- Magnesium sacrificial anode design to help protect the tank's internal surfaces
- Supplied as a matched kit for service of Aqua-Plus units that specify 633-500-014
Compatibility & Applications:
- Intended for use with Weil-McLain Aqua-Plus 35, 45, 55, and 85 indirect water heater models that list this kit in the official parts information
- Used as part of routine tank maintenance or when inspection shows a depleted anode
- Suitable for residential and light commercial installations where Aqua-Plus water heaters are installed on hydronic systems
Installation & Operation Notes:
- Shut off power to the boiler and circulator, and close isolation valves to the Aqua-Plus unit before servicing
- Relieve pressure and follow the Aqua-Plus installation and maintenance instructions for draining to a safe level before removing the existing anode assembly
- Use the recommended socket size to remove the old anode assembly from the tank opening, then install the new anode, O-ring, insulating washer, and brass bushing from the kit
- Tighten to the torque specified in Weil-McLain literature and restore system pressure, then check for leaks at the anode connection
Maintenance & Troubleshooting:
- Inspect the anode condition during scheduled tank maintenance and replace when significantly consumed or as recommended by Weil-McLain
- If signs of premature tank corrosion, odor complaints, or discolored water occur, inspect the anode and other tank components as part of the diagnostic process
- Do not operate the Aqua-Plus tank without a properly installed anode where specified, since corrosion protection may be reduced
