9USER’S INFORMATION MANUALSL SERIES BOILERSMAINTENANCEDaily Maintenance• Check the surrounding area – inspect for water leaks in the general areaaround the boiler and boiler piping• Check the system pressure. The heating system pressure should not exceed25psi (SL 80-399 - 75psi) and not drop below 10psi in most applications. If thepressure is outside this normal range or if the water pressure fluctuates morethan 2-3psi, contact your qualified service technician for service.• Check the area around the boiler and the air intake opening for obstructionsand chemical contaminates.Monthly Maintenance• Check all the Daily Maintenance items.• Check the pressure relief valve and discharge piping for signs of leakageor moisture. If water or moisture is found, contact your qualified servicetechnician as soon as possible for service.• Check the condensate trap and outlet pipe. The condensate trap shall be fullof water. The outlet hose may be connected to a condensate neutralizer, if so,check the pH of the water coming out of the neutralizer is above 6.0pH. If thepH is below 6.0 then the neutralizer will need to be re-charged or replaced.Contact your qualified service technician for service.• Inspect the flue gas exhaust and air intake connections. All connectionsshould be tight and leak free.• Inspect flue gas exhaust piping, combustion air piping and terminations.Annual MaintenanceThe boiler must be inspected by your qualified service technician for the following:• Check the Error Logs for any issues.• Inspect the flue gas exhaust and air intake connections. All connectionsshould be tight and leak free.• Inspect flue gas exhaust piping, combustion air piping and terminations.• Inspect the boilers interior and vacuum if required.• Check for water, gas and condensate leaks in the boiler and around the boiler.• Check the condensate trap and clean if required. Re-fill the trap and re-installthe trap hook.• Check the water pressure, expansion tank and pumps.• Check the electrical connections.• Check the ignition electrode and remove oxidation from the electrode.Replace if necessary.• Check the gas valve and ignition cable.• Check the controller settings.• Check the burners flame. Should be a quick and quiet ignition across the fullburner.• If required, clean the heat exchanger and the burner.WARNINGAnnual Maintenance must onlybe done by a qualified servicetechnician.CAUTIONThe heat exchanger has a smallamount of combustion chamberinsulation (refractory), whichcontains ceramic fibers. Whenexposed to extremely hightemperatures, the ceramic fibers,which contain crystalline silica,can be converted into cristobalite- which is classified as a possiblehuman carcinogen.Care should be taken to avoiddisturbing or damaging therefractory. If damage occurs,contact the factory for directions.Avoid breathing and contact withskin and eyes and follow theseprecautions:1. For conditions of frequentuse or heavy exposure,respirator protection isrequired. Refer to the “NIOSHGuide to the Selection andUse of Particulate RespiratorsCertified under 42 CFR84” for selection and useof respirators certified byNIOSH. For the most currentinformation, NIOSH can becontacted at 1-800-356-4676or on the web at www.cdc.gov/niosh.2. Wear long sleeved, loosefitting clothing, gloves andeyes protection.3. Assure adequate ventilation.4. Wash with soap and waterafter contact.5. Wash potentiallycontaminated clothesseparately from otherlaundry and rinse washingmachine thoroughly.6. Discard used insulation in anair tight plastic bag.NIOSH stated first aid:• Eye contact - Irrigate andwash immediately.• Breathing - Provide fresh air.
