See the Massachusetts Board of Plumbers and Gas Fitters website, [http://license.reg.state.ma.us/pubLic/pl_products/pb_pre_form.asp](http://license.reg.state.ma.us/pubLic/pl_products/pb_pre_form.asp) for the latest Approval Code or ask your local Sales Representative.  \nThe Commonwealth of Massachusetts requires this product to be installed by a Licensed Plumber or Gas Fitter.  \nThe following terms are used throughout this manual to bring attention to the presence of hazards of various risk levels, or to important information concerning product life.  \n\n| DANGER |\n| --- |\n| Indicates an imminently hazardous situation which, if not avoided, will result in death, serious injury or substantial property damage. |\n\n\n| WARNING |\n| --- |\n| Indicates a potentially hazardous situation which, if not avoided, could result in death, serious injury or substantial property damage. |\n\n\n| CAUTION\u003Cbr>|\n| --- |\n| Indicates a potentially hazardous situation which, if not avoided, may result in moderate or minor injury or property damage. |\n\n\n| NOTICE |\n| --- |\n| Indicates special instructions on installation, operation, or maintenance which are important but not related to personal injury hazards. |\n\n\n| CAUTION\u003Cbr>|\n| --- |\n| If, during normal operation, it is necessary to add water to this boiler more frequently than once a month, consult a qualified service technician to check your system for leaks. A leaky system will increase the volume of make-up water supplied to the boiler which can significantly shorten the life of the boiler. Entrained in make-up water are dissolved minerals and oxygen. When the fresh, cool make-up water is heated in the boiler the minerals fall out as sediment and the oxygen escapes as a gas. Both can result in reduced boiler life. The accumulation of sediment can eventually isolate the water from contacting the cast iron. When this happens the cast iron in that area gets extremely hot and may eventually crack. The presence of free oxygen in the boiler creates a corrosive atmosphere which, if the concentration becomes high enough, can corrode the cast iron through from the inside. Since neither of these failure types are a result of a casting defect the warranty does not apply. Clearly, it is in everyone's best interest to prevent this type of failure. The maintenance of system integrity is the best method to achieve this. |\n\n\n| NOTICE |\n| --- |\n| This boiler has a limited warranty, a copy of which is included with this boiler.\u003Cbr>It is the responsibility of the installing contractor to see that all controls are correctly installed and are operating properly when the installation is complete.\u003Cbr>Surface rust on cast iron sections may be attributed to the manufacturing process as well as condensation during storage. Surface rust is normal and does not affect the performance or longevity of a boiler. |\n\n\n| CAUTION\u003Cbr>|\n| --- |\n| Probe type low water cutoff devices require annual inspection and maintenance! Although these devices are solid state in their operation, the probe is exposed to possible contamination in the boiler ","cbCaist2HZmy7luR","https://ap.wps.com/l/cbCaist2HZmy7luR","pdf",6377473,96,"English","# Safety and Hazard Definitions\n## DANGER\n## WARNING\n## CAUTION\n## NOTICE\n# Installation and Regulatory Requirements\n# System Integrity and Make-Up Water Risks\n# Warranty and Contractor Responsibilities\n# Low Water Cutoff Maintenance\n# Ongoing Service and Safe Operation","[{\"question\":\"Who must supervise the installation of the Independence® gas-fired boiler?\",\"answer\":\"A Licensed Master Plumber must supervise the installation in New York City, and Massachusetts requires installation by a Licensed Plumber or Gas Fitter.\"},{\"question\":\"What should be done if more than one month of make-up water is needed during normal operation?\",\"answer\":\"Consult a qualified service technician to check the system for leaks, since additional make-up water increases sediment and oxygen-related corrosion risks.\"},{\"question\":\"How often must probe type low water cutoff devices be inspected and maintained?\",\"answer\":\"They require annual inspection and maintenance due to potential contamination and fouling of the probe.\"}]","Independence Gas-Fired Boiler - Installation, Operating and Service Instructions | PDF",1792778591,242]
