Manual Part Number 550-143-075/0125 SIMPLICITYTM 110/150/199 User's Information Manual Stop!! -- Read Before Proceeding Should overheating of boiler occur or gas supply fail to shut off, DO NOT turn off or disconnect electrical supply to circulator. Instead, shut off the gas supply at a location external to the appliance. y If any part of a boiler, burner or its controls has been sprayed with or submerged under water, either partially or fully, DO NOT attempt to operate the boiler until the boiler has been either replaced or completely repaired, inspected, and you are sure that the boiler and all components are in good condition and fully reliable. y Otherwise, by operating this boiler, you will cause a fire or explosion hazard, and an electrical shock hazard, leading to serious injury, death, or substantial property damage. See the instructions at right. Saltwater Damage -- The exposure of boiler components to saltwater can have both immediate and long-term effects. While the immediate effects of saltwater damage are similar to those of freshwater (shorting out of electrical components, washing out of critical lubricants, etc.), the salt and other contaminants left behind can lead to longer term issues after the water is gone due to the conductive and corrosive nature of the salt residue. Therefore, Weil-McLain equipment contaminated with saltwater or polluted water will no longer be covered under warranty and should be replaced. Electrical Damage -- If any electrical component or wiring came into contact with water, or was suspected to have come into contact with water, do not use this boiler. Immediately call a qualified service technician to inspect the boiler and to replace any part of the control system and any gas control that has been in contact with water. Failure to adhere to the guidelines on this page can result in severe personal injury, death or substantial property damage. Boiler Service and Maintenance -- y To avoid electric shock, interrupt electrical supply before performing maintenance. y To avoid severe burns, allow boiler to cool before performing maintenance. y You must maintain the boiler as outlined in the manual and have the boiler started up and serviced at least annually by a qualified service technician to ensure boiler/system reliability. Carbon Monoxide Detector -- y This product burns gas to produce heat. The appliance must be properly installed, operated, and maintained to avoid exposure to appreciable levels of carbon monoxide and the installer is required to confirm that at least one carbon monoxide alarm is installed in the living space before the appliance is put into operation. It is important for the carbon monoxide alarms to be installed, maintained, and replaced following the alarm manufacturer's instructions and applicable local codes. Boiler Operation -- y Do not block flow of combustion or ventilation air to boiler. This boiler is equipped with a control which will automatically shut down the boiler should air or vent be blocked. If vent or air blockage is easily accessible and removable, remove it. The boiler should attempt to restart within an hour. If blockage is not obvious or cannot be removed, have the boiler and system checked by a qualified service technician. Combustion Air -- y DO NOT obstruct the combustion air intake or expose the air intake to corrosive chemicals (see next page). Water Chemistry Water quality must be maintained as described in boiler manual. Water pH between 7.0 and 8.5 y Maintain boiler water pH between 7.0 and 8.5. Check with litmus paper or have chemically analyzed by water treatment company. y If pH differs from above, consult local water treatment company for treatment needed. Hardness less than 7 grains Consult local water treatment companies for unusually hard water areas (above 7 grains hardness). Chloride Concentration must be Less than 50 Ppm y Filling with chlorinated fresh water should be acceptable since drinking water chloride levels are typically less than 5 ppm. y Do not use the boiler to directly heat swimming pool or spa water. y Do not fill boiler or operate with water containing chloride in excess of 50 ppm. Freeze Protection Fluids -- y NEVER use automotive or standard glycol antifreeze. Use only freeze-protection fluids made for hydronic systems. Follow all guidelines given by the antifreeze manufacturer. Thoroughly clean and flush any replacement boiler system that has used glycol before installing the new boiler. Use only the products listed by Weil-McLain for use with this boiler. See boiler manual for details. Boiler Water -- y Do not use petroleum-based cleaning or sealing compounds in boiler system. Gaskets and seals in the system may be damaged. This can result in substantial property damage. y Leaks in boiler or piping must be repaired at once to prevent make-up water. Use this boiler ONLY in a closed-loop system. Continual fresh make-up water will reduce boiler life. Mineral buildup in heat exchangers reduces heat transfer, overheats the materials, and causes failure. Addition of oxygen carried in by make-up water can cause internal corrosion. y Do not add cold water to hot boiler. Thermal shock can cause heat exchanger to crack. Frozen Water Damage Hazard Residences or buildings that are unattended in severely cold weather, boiler system components failures, power outages, or other electrical system failures could result in frozen plumbing and water damage in a matter of hours. For your protection, take preventative actions such as having a security system installed that operates during power outages, senses low temperature, and initiates an effective action. Consult with your boiler contractor or a home security agency.
