Wiring errors can causeimproper and dangerous operation! Verify properoperation after servicing.ATTENTION. Au moment de l'entretien des commandes,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 must be madein accordance with all applicable local codes and thelatest revision of the National Electrical Code, ANSI /NFPA-70. Installation should also conform with CSAC22.1 Canadian Electrical Code Part I if installed inCanada. Install a separate 120 volt 15 amp circuit forthe boiler. A properly rated shut-off switch should belocated at the boiler. The boiler must be grounded inaccordance with the authority having jurisdiction, or ifnone, the latest revision of the National Electrical Code,ANSI/NFPA-70.NOTE: An inline gas regulator must be installed upstream of the gas train and set to the lowestexpected service pressure. Choose a regulator thathas no more than 1" pressure drop.CAUTION: Always use a wrench on the gas valvebody when making gas connections to it. Neverover-tighten the piping entering the gas valve bodyor gas valve failure may result!Safe lighting and other performance criteria were metwith the gas manifold and control assembly provided onthe boiler. All gas connections MUST be leak testedbefore putting the boiler into operation.WARNING: Never use an open flame to test forgas leaks. Always use an approved leakdetection method. Failure to comply with thiswarning can cause extensive property damage,severe personal injury or death!Whenever the gas supply piping is pressure tested theboiler gas controls must be protected. If the testpressure is equal to, or less than 1/2 psig, 3.5 kPaisolate the boiler by closing its' manual shut off valve,see Figure 14. If the test pressure is greater than, orequal to 1/2 psig, 3.5 kPa, disconnect the boiler andits individual shut-off valve.Line voltage field wiring of any controls or other devicesmust use copper conductors with a minimum size of #14awg. Use appropriate wiring materials for units installedoutdoors.Refer to the wiring diagram supplied with the boiler forproper wiring connections.BOILER OPERATIONWARNING: Before proceeding read and fullyunderstand the instructions contained in thismanual. Do not attempt to operate this boiler ifit has not been installed in accordance with theguidelines set forth in this manual. Failure tocomply with this warning can result in extensiveproperty damage, severe personal injury ordeath!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.En cas de surchauffe ou si l'alimentation en gaz nes'arrête pas, fermez manuellement le robinet d'arrêt del'admission de gaz.
