Part 1 - General Safety Information

WARNING

B. Improper Combustion

WARNING DO NOT USE THIS BOILER IF ANY PART HAS BEEN SUBMERGED IN WATER. Immediately call a qualiÀed service technician. The boiler MUST BE replaced if it has been submerged. Attempting to operate a boiler that has been submerged could create numerous harmful conditions, such as a potential gas leakage causing a Àre and/ or explosion, or the release of mold, bacteria, or other harmful particulates into the air. Operating a previously submerged boiler could result in property damage, severe personal injury, or death. NOTE: Boiler damage due to Áood or submersion is considered an Act of God, and IS NOT covered under product warranty. DO NOT alter or modify the appliance or appliance controls. Altering any NTI boiler with parts not manufactured by NTI WILL INSTANTLY VOID the boiler warranty and could result in property damage, personal injury, or death. Due to the low water content of the boiler, improper sizing of the boiler with regard to heating system load will result in excessive cycling and accelerated component failure. DO NOT under or oversize the boiler to the system. Modular boiler installations greatly reduce the likelihood of boiler oversizing. NTI DOES NOT warrant failures caused by improperly sized boiler applications. High heat sources (sources generating heat 100 o F / 37 o C or greater, such as stove pipes, space heaters, etc.) may damage plastic components of the boiler as well as plastic vent pipe materials. Such damages ARE NOT covered by warranty. It is recommended to keep a minimum clearance of 8” from high heat sources. Observe heat source manufacturer instructions, as well as local, state, provincial, and national codes, laws, regulations and ordinances when installing this boiler and related components near high heat sources. CAUTION Do not use this boiler for anything other than its intended purpose (as described in this manual). Doing so could result in property damage and WILL VOID product warranty. This appliance is equipped with a three prong plug. It should only be plugged directly into a properly grounded three prong receptacle. DO NOT remove the ground plug from the plug. This appliance provides an overheat shutdown limit. In the event the appliance water temperature exceeds the setpoint of the control limit, the cutoff will trip and the appliance will shut down. Certain local codes require additional temperature limits. In addition, certain types of systems may operate at temperatures below the minimum setpoint of the limit provided with the appliance. Contact the manufacturer for additional overheat controls. NOTICE

WARNING

Do not obstruct the Áow of combustion and ventilating air. Adequate air is necessary for safe operation. Failure to keep the exhaust vent and combustion air intake clear of ice, snow, or other debris could result in property damage, serious personal injury, or death.

C. Gas Should overheating occur or gas supply fail to shut o , turn o the manual gas control valve to the boiler.

D. When Servicing the Boiler

WARNING

• To avoid electric shock, disconnect electrical supply before performing maintenance. • To avoid severe burns, allow boiler and associated equipment to cool before servicing. • Do not use petroleum-based cleaning or sealing compounds in boiler system. Gaskets and seals in the system may be damaged, possibly resulting in substantial property damage. • Do not use “homemade cures” or “boiler patent medicines”. Substantial property damage, damage to the boiler, and/or serious personal injury may result. • Always verify proper operation after servicing the boiler. NOTE: When inquiring about service or troubleshooting, reference the model and serial numbers from the boiler rating label. Be sure to disconnect electrical power before opening boiler cabinet or performing service. Label all wires while performing service to ensure proper re-wiring of the appliance. Wiring errors can cause improper or dangerous operation. Failure to do so could result in electrical shock, improper boiler or system operation, property damage, serious personal injury, or death. Thoroughly ush the system (without the boiler connected) to remove sediment. The high-e ciency heat exchanger can be damaged by build-up or corrosion due to sediment. The manufacturer recommends a suction strainer in this type of system. • Do not use petroleum-based cleaning or sealing compounds in boiler system. Gaskets and seals in the system may be damaged, possibly resulting in substantial property damage. • Do not use “homemade cures” or “boiler patent medicines”. Substantial property damage, damage to boiler, and/or serious personal injury may result. • Continual fresh make-up water will reduce boiler life. Mineral buildup in the heat exchanger reduces heat transfer, overheats the stainless steel heat exchanger, and causes failure. Addition of oxygen from make-up water can cause internal corrosion in system components. Leaks in the boiler or piping must be repaired at once. NOTE: DO NOT add cold make up water to the system when the boiler is hot. Thermal shock can potentially cause cracks in the heat exchanger. Such damage IS NOT covered by warranty. E. Boiler System •
