Common problems and solutions

Symptom Common Causes Possible Corrections

Rapid cycling — boiler turns on and off frequently

Thermostat installed where drafts or heat affect reading

Locate thermostat on inner wall away from heat sources or cool drafts.

Heat anticipator in thermostat adjusted incorrectly

Adjust thermostat per manufacturer's instructions.

Incorrect limit setting Set limit according to system needs. Maximum setting is 220˚F. Increase limit setting to decrease cycling.

Insufficient water flow through boiler

Check all valves to and from boiler. Return to proper setting.

Confirm circulator size.

Frequent release of water through relief valve

Expansion tank sized too small Call qualified service technician to check expansion tank operation and size.

Flooded expansion tank Call qualified service technician to check expansion tank operation.

Inoperative limit control Call qualified service technician to replace limit control.

Need to frequently add makeup water

Leaks in boiler or piping Have qualified service technician repair leaks at once to avoid constant use of makeup water. Makeup water can cause mineral deposits which, in turn, can cause boiler section failure. Do not use petroleum-base stop-leak compounds.

Black water condition

Oxygen corrosion due to leaks in boiler and piping

Have qualified service technician repair at once. Keep pH of water between 7.0 to 8.5.

Popping or percolating noise heard in boiler

Mineral deposits in sections due to constant use of makeup water

Call qualified service technician to de-lime boiler, if necessary. In some cases, deposits will be too heavy to remove with de-liming procedures.

Have qualified service technician repair leaks to eliminate need for constant makeup water.

Incorrect pH of boiler water Call qualified service technician to check pH level and correct. pH should be maintained between 7.0 to 8.5.

Insufficient water flow through boiler

Check all valves to and from boiler. Return to proper setting.

Confirm circulator size.

Metal flakes found in vent outlet or vent — flueway corrosion

Contaminated combustion air supply — See page 3 in this manual.

Remove any contaminating products. See page 3 in this manual.

Provide outside air for combustion. Kit available through Weil-McLain distributor. Have qualified service technician pipe-up kit.

Condensation of combustion gases in boiler sections

Have qualified service technician inspect system piping and controls to verify proper regulation of return water temperature.

Some radiators or baseboard units do not heat or are noisy

Air in system Bleed air from system through air vents in radiators or baseboard units.

Low system pressure Fill to correct pressure.

Check for leaks in boiler or piping. Have qualified service technician repair at once.

High limit set too low Adjust high limit to higher setting.
