LCD INSTALLATION AND OPERATION INSTRUCTIONSPage 2815. Set the operating control or thermostat to thedesired setting.16. The pilot should automatically light. Do not try tolight the pilot by hand!17. The burners should light with proper boiler/waterheater operation.18. The pilot and manifold pressures shouldmatch those listed in Table 19. To adjust themanifold gas pressure see the “GAS PRESSUREADJUSTMENT” instructions in the “CHECKINGAND ADJUSTMENT” section.Provide gas supply pressure at inlet to boiler gas trainas follows:LP NatMinimum (in WC) 11 6Maximum (in WC) 14 14Measure pressure when the boiler is firing at full rate.Low gas pressure could indicate undersized gas line orinsufficient gas supply.Static and operating gas pressure required at the gasvalve inlet is between 6" W.C. and 14" W.C. for naturalgas and 11" W.C. and 14" W.C. for propane. If the gaspressure is above this limit, a lock-up style regulatorsuitable for dead end service such as an Equimeter orFisher must be installed to prevent increase (creep) ofgas pressure when the units are not operating. Thispressure regulator (supplied by others) may be installedat the service entrance to each unit or a “master”regulator sized to handle multiple units may be utilized.Consult local gas utility or regulator manufacturer forrecommendations to meet specific job site requirements.Table 19 - Pilot & Manifold PressuresInstructions De Mise En Marche1. ARRÊTEZ! Lisez les instructions de sécurité sur laportion supérieure de cette étiquette.2. Réglez le thermostat à la température la plus basse.3. Coupez l’alimentation électrique de l’appareil.4. Cet appareil est muni d’un dispositif d’allumage quiallume automatiquement la veilleuse. Ne tentez pasd’allumer la veilleuse manuellement.5. Fermer la vanne manuelle d’arrêt d’alimintation degaz.6. Attendre cinq (5) minutes pour laisser échapper toutle gaz. Reniflez tout autour de l’appareil, y comprisprès du plancher, pour déceler une odeur de gaz.Si vous sentez une odeur de gaz, ARRÊTEZ!Passez à l’étape B des instructions de sécurité surla portion supérieure de cette étiquette. S’il n’y apas d’odeur de gaz, passez à l’étape suivante.7. Ouver la vanne manuelle d’arrêt d’alimintation degaz.8. Mettez l’appareil sous tension.9. Réglez le thermostat à la température désirée.10. Si l’appareil ne se met pas en marche, suivez lesinstructions intitulées couper l’admission de gaz del’appareil et appelez un technicien qualifié ou lefournisseur de gaz.To Turn Off Gas To Appliance1. Set the operating control or thermostat to its lowestsetting.2. Turn off all electric power to the appliance if serviceis to be performed.3. Close the manual main valves.COUPER L’ADMISSION DE GAZ DE L’APAREIL1. Réglez le thermostat à la température la plus basse.2. Coupez l’alimentation électrique de l’appareil s’il fautprocéder à l’entretien.3. Fermer la vanne manuelle d’arrêt d’alimintation degaz.CHECKING & ADJUSTMENT1. With the burners in operation, close the manualshutoff valve in the gas supply line. As soon as themain burner flames go out, open the manual shutoffvalve. A normal ignition sequence should take place.If the burners fail to light, the gas valves will closeand the system will go into a 5-minute lock outperiod. The flame sense module will then make asecond ignition attempt. If the unit won’t light ensurethat the gas piping is fully purged of air. Inspect theignition system and ensure that it is operatingproperly.2. To test the ignition safety shutoff device, close themanual shutoff valve in the gas supply line. Within5 seconds of main burner flame extinction, the maingas valve solenoid should close with an audiblenoise. After 10 seconds the module should lockoutand the trial for ignition end. After 5 minutes asecond trial for ignition should occur. Open themanual shutoff valve in the gas supply line and resetthe ignition control system. A normal ignitionsequence should take place.3. With the burners in operation, interrupt the powerto the control circuit by turning down the operatoror thermostat. The boiler/water heater should shutdown. Reset the operating control or thermostat. Anormal ignition sequence should follow.LCD-225, 300 & LCD-400 to 12001480 to 2300Natural Gasinches W.C.mm W.C. inches W.C.mm W.C.Low Fire* 1.3 ± 0.233 ± 5 1.6 ± 0.241 ± 5High Fire 2.5 ± 0.264 ± 5 2.5 ± 0.264 ± 5LP Gasinches W.C.mm W.C. inches W.C.mm W.C.Low Fire* 3.6 +/- 0.291 ± 5 4.0 ± 0.2102 ± 5High Fire 8.0 +/- 0.2204 ± 5 8.0 ± 0.2204 ± 5*Optional
