Tft Series Installation and Operation Instructions │Trinity5111.0 FIELD WIRINGAll wiring must be in accordance with the Canadian Electrical code, CSA C22.2 and any applicable local codes.Ensure that the wiring complies with this manual. The boiler must be electrically grounded in accordance withthe National Electrical Code ANSI/NFPA 70, local codes, and/or the Canadian Electrical Code CSA C22.1.Avoid Shocks - To Avoid Electrical Shock, turn off electrical power to the boiler prior toopening any electrical box within the unit. Ensure the power remains off while anywiring connections are being made. Failure to follow these instructions may result in component failure, seriousinjury or death.Field Wiring - Wire grommets must be used to secure wiring and prevent chafing whenpassing wiring through the cabinet wall. Failure to follow instructions may damage unit.Line Voltage ConnectionsElectrical rating for the Trinity Tft is 120V / 1 Phase / 60 Hz / 12A. All line voltage wiring connections to theTrinity Tft are made at the junction box in the control panel located at the bottom of the boiler cabinet. Theconnections are accessed by removing the front door of the boiler, followed by the removal of the control panelcover. Field connections are to be installed in accordance with Figure 11-1 and Table 11-1. Holes are located onthe bottom (underside) of the control panel junction box.Fuses (120VAC) – The Trinity Tft is equipped with two 7 Amp fuses to protect 120VAC system components.The fast-acting fuses are located on the left side of the control panel and are easily accessed upon removal of thefront cover of the boiler cabinet.• Fuse A: Protects the blower, spark generator and PUMP B output circuits.• Fuse B: Protects PUMP A and PUMP C output circuits.Wire Protection - When passing any wiring through the cabinet of the boiler, theinstaller must use wire grommets suitable for securing the wiring and preventing chafing.Failure to follow instructions may result in component failure, serious injury or death.Power Supply - The Trinity Tft is designed to be powered using a single phase 120VACpower supply that is fused (or protected via a circuit breaker) to allow a maximum of 15Amps. Failure to follow instructions may result in component failure, serious injury or death.Labeling - Label all wires prior to disconnecting them when servicing controls. Wiringerrors can cause improper and dangerous operation. Failure to follow instructions mayresult in property damage or personal injury.Continuity - Before connecting the line voltage wiring, perform a continuity checkbetween all wires and ground to make sure that there are no electrical leaks that couldblow a fuse or damage electrical components. Also check the polarity of the line and neutral wires. Line mustmeasure 120VAC to ground; neutral must measure zero. Failure to follow instructions may damage the unit.Max Load - Circulator outputs (PUMP A, B, C) are each limited to operating a circulatorwith a maximum current load of 3 Amps or a maximum 1/6 hp motor. See Table 11-1.
