Maintenance ProceduresCheck Expansion TankRefer to Section IV - Boiler Piping for recommendedlocation of the expansion tankand air eliminators.Close -Type Tank:- Ensure tank is partially filled withwater leaving an air gap as a cushion.Refer to the manufacturer’s instructionfor proper fill level.- Ensure the tank is fitted with a devicethat reduces gravity circulation of airsaturatedtank water back into the system.This device prevents air frombubbling up through the water as itreturns from the system.- Ensure no automatic air vents are usedin the system. This will allow air toescape from the system instead ofreturning to the tank.Diaphragm Tank:- Ensure the system contains a minimum ofone automatic air vent. Recommendedlocation of the air vent should be atop anair eliminator.- Remove the tank from the system andcheck the charge pressure. For residentialapplications the charge pressure istypically 12 psig. If tank does not holda charge pressure, then the membrane isdamaged and the tank should bereplaced.Check Boiler Relief ValveInspect the relief valve and lift the lever to verifyflow at least annually or as recommendedon the warning tag of the valve.WARNINGBefore manually operating the pressurerelief valve, ensure the discharge piping isdirected to a suitable place of disposal toavoid a potential scald hazard. The dischargepiping must be full size withoutrestriction and installed to permit completedrainage of both the valve and line.If after closing the valve, the valve fails to seatproperly or continually weeps, replace therelief valve. Ensure the cause of the reliefvalve to weep is the valve itself, not due to systemover-pressurization caused by an expansiontank that is waterlogged or undersized.Inspection of Ignition ElectrodeRemove the ignition electrode from the burnermounting plate.Remove any white oxides accumulated on theelectrode using fine grit sandpaper or steel wool.If the electrode does not clean to a satisfactorycondition, replace the ignitor .When replacing the ignition electrode, ensurethe gasket is in good condition and correctlypositioned, replace gasket if necessary.Check Ignition Wiring and Ground WiringInspect the burner wiring from the burner controlmodule to the ground terminal behind thecontrol panel.Ensure wiring is in good condition and securelyconnected.Check ground continuity of the wiring to theboiler jacket or piping using a continuity meter.Replace and correct ground wire if ground continuityis not completed and satisfactory.61
