If you frequently need to add makeup water to your Weil-McLain Boiler, it is likely due to leaks in the boiler or piping. It is important to have a qualified service technician repair these leaks immediately to avoid constant use of makeup water, which can lead to mineral deposits and potential boiler section failure. Avoid using petroleum-based stop-leak compounds.
Why are some radiators or baseboard units in my Weil-McLain Boiler system not heating or are noisy?
If some radiators or baseboard units in your Weil-McLain boiler system are not heating or are noisy, possible causes include air in the system, low system pressure or a high limit set too low. Try bleeding air from the system through air vents in the radiators or baseboard units, and ensure the system is filled to the correct pressure. Adjust the high limit to a higher setting. Also, check for leaks in the boiler or piping and have a qualified service technician repair them immediately.
Why is my Weil-McLain LGB-6 Boiler frequently releasing water through the relief valve?
Frequent release of water through the relief valve can occur if the expansion tank is sized too small or has become flooded. It can also happen if the limit control is inoperative. In these cases, it is recommended to call a qualified service technician to check the expansion tank operation and size or to replace the limit control.
What to do if my Weil-McLain LGB-6 is rapidly cycling on and off?
Rapid cycling of your Weil-McLain Boiler, where it turns on and off frequently, can be due to several factors. First, check if the thermostat is installed in an area affected by drafts or heat, and if so, relocate it to an inner wall away from these sources. Also, ensure the heat anticipator in the thermostat is correctly adjusted per the manufacturer’s instructions. Verify that the limit setting is appropriate for your system needs, keeping in mind the maximum setting is 220°F—increasing the limit setting can reduce cycling. Check that all valves to and from the boiler are properly set to ensure sufficient water flow. Finally, confirm the circulator size.
Why is my Weil-McLain Boiler making popping or percolating noises?
Popping or percolating noises in your Weil-McLain boiler can be caused by several factors. Mineral deposits in the sections, resulting from constant use of makeup water, can be a cause. Insufficient water flow through the boiler or an incorrect pH level of the boiler water may also be responsible. In such cases, it is recommended to check all valves to and from the boiler and return them to the proper setting, and to confirm the circulator size. Contact a qualified service technician to check the pH level and correct it, ensuring it is maintained between 7.0 and 8.5. Also, have them repair any leaks to eliminate the need for constant makeup water and to de-lime the boiler, if necessary.
Why is the water in my Weil-McLain LGB-6 black?
A black water condition in your Weil-McLain boiler is typically caused by oxygen corrosion due to leaks in the boiler and piping. Have a qualified service technician repair these leaks at once, and ensure the pH of the water is maintained between 7.0 and 8.5.
What causes metal flakes in the vent outlet of my Weil-McLain Boiler?
Metal flakes found in the vent outlet or vent of your Weil-McLain Boiler, indicating flueway corrosion, can be caused by a contaminated combustion air supply or condensation of combustion gases in boiler sections. Remove any contaminating products and provide outside air for combustion. Have a qualified service technician inspect the system piping and controls to verify proper regulation of return water temperature.
