SERIES 8800 & 8900 INSTALLATION AND OPERATING INSTRUCTIONSPage 20Whenever the gas supply piping is pressure tested theboiler/water heater gas controls must be protected.If the test pressure is equal to, or less than 1/2 psig,3.5 kPa isolate the boiler/water heater by closing it’smanual shut off valve, see Figure 14. If the test pressureis greater than, or equal to 1/2 psig, 3.5 kPa, disconnectthe boiler/water heater and its individual shut-off valve.ELECTRICAL WIRINGElectrical Power ConnectionsCAUTION: Label all wires prior to disconnectionwhen servicing controls. Wiring errors can causeimproper and dangerous operation! Verify properoperation after servicing!ATTENTION. Au moment de l’entretien descommandes, étiquetez tous les fils avant de lesdébrancher. Des erreurs de câblage peuvententraîner un fonctionnement inadéquat etdangereux. S’assurer que l’appareil fonctionneadéquatement une fois l’entretirn terminé.The electrical connections to this boiler/water heatermust be made in accordance with all applicable localcodes and the latest revision of the National ElectricalCode, ANSI /NFPA-70. Installation should also conformwith CSA C22.1 Canadian Electrical Code Part I ifinstalled in Canada.Install a separate 120 volt 15 amp circuit for the boiler/water heater. A shut-off switch should be located at theboiler/water heater. The boiler/water heater must begrounded in accordance with the authority havingjurisdiction, or if none, the latest revision of the NationalElectrical Code, ANSI/NFPA-70.Line voltage field wiring of any controls or other devicesmust conform to the temperature limitation of type T wireat 95°F, 35°C above room temperature. Use copperconductors with a minimum size of #14 awg.Refer to the wiring diagram supplied with the boiler/water heater for proper wiring connections.GENERAL OPERATIONWARNING: Before proceeding read and fullyunderstand the instructions contained in thismanual. Do not attempt to operate this boiler/water heater if it has not been installed inaccordance with the guidelines set forth in thismanual. Failure to comply with this warning canresult in extensive property damage, severepersonal injury or death!Should overheating occur or the gas supply fail to shutoff, turn off the manual gas control valve to theappliance. Do not interrupt water flow through the boiler/water heater.En cas de surchauffe ou si l’alimentation en gaz nes’arrête pas, fermez manuellement le robinet d’arrêt del’admission de gaz.Hydronic Heating BoilersOpen the make-up water valve and slowly fill the boilerand all of the radiation with water. Ensure that all bleedand drain valves are closed.Adjust the make-up water pressure regulator so aminimum 12 psig, 82.7kPa system pressure ismaintained at the highest point in the system piping. Ifa make-up water pump is used adjust it to maintain aminimum 12 psig, 82.7 kPa system pressure.Open the system bleed and drain valves, one at a time,to purge the air trapped in the heating system piping.With the boiler off, run the system pump for at least 30minutes and bleed the system piping using the bleedvalves. If strainers are used in the system piping, themake-up water valve should be closed and the strainerschecked and cleaned.The system expansion tank should be checked toensure that the correct water level in the tank ismaintained. The tank should be less than half fullof water with the system full and adjusted to the correctoperating pressure.Start the boiler as described in the “OPERATINGINSTRUCTIONS” section. Run the boiler for at least anhour. The system pump(s) and all radiation units mustbe operated during this time. Ensure that the make-upwater valve is open.
