92Part 14 - MaintenanceA. ProceduresPeriodic maintenance should be performed once a year by a qualifiedservice technician to ensure that all the equipment is operating safelyand efficiently. The owner should make necessary arrangements witha qualified heating contractor for periodic maintenance of the boiler.The installer must also inform the owner that a lack of proper care andmaintenance of the boiler may result in a hazardous condition.Check the Surrounding AreaEnsure the Cabinet is Closed When the Boiler is OperatingThe boiler cabinet must be closed when the boiler is operating.Combustible/Flammable MaterialsDo not store combustible materials, gasoline, or other flammablevapors or liquids near the boiler. If found, remove these materialsimmediately.Air ContaminantsIf allowed to contaminate combustion air, products containing chlorineor fluorine will produce acidic condensate that will cause significantdamage to the boiler. Read the list of potential contaminants and areaslikely to have these contaminants in Table 6. If any of these contaminantsare in the room where the boiler is located, or combustion air is takenfrom one of the areas listed, the contaminants must be removedimmediately or the intake pipe must be relocated to another area.Check the Power SourceMake sure the power cord and the main power line are properlyconnected to the manual switch box inside the boiler.Check the Status of the Control PanelObserve the Control Panel to ensure the boiler is powered on and tocheck for any error codes. Clear any debris from the panel.Check CH Pressure GaugeEnsure the pressure reading on the CH gauge does not exceed 30 psig.Higher pressure readings may indicate a problem with the expansiontank. Immediately contact a qualified service technician to inspect theboiler and system.B. Maintenance That May be Performed by the UserCheck Exhaust Vent and Intake Pipe TerminationsVerify that the boiler exhaust vent and intake pipe terminations areclean and free of obstructions. Remove any debris from the exhaustvent or intake pipe openings. If removing the debris does not allow theboiler to operate correctly, contact your qualified service technician toinspect the boiler and the vent system.Check Exhaust Vent and Intake PipingVisually inspect the exhaust vent for any signs of blockage, leakage, ordeterioration of the piping. Inspect the exhaust vent bracing. Ensurebracing is undamaged and in good condition. Notify a qualified servicetechnician immediately if any problems are found.Check Pressure Relief Valve1. Visually inspect the primary pressure relief valve and discharge pipefor signs of weeping or leakage.2. If the pressure relief valve often weeps, the expansion tank maynot be operating properly. Immediately contact a qualified servicetechnician to inspect the boiler and system.Operate Pressure Relief Valve1. Before proceeding, verify that the relief valve outlet has been pipedto a safe place of discharge, avoiding any possibility of scaldingfrom hot water.2. Shut power off to the boiler. To avoid scalding, wait for boiler to coolbefore operating the relief valve.3. Lift the relief valve lever. If water flows freely, release the lever andallow the valve to seat. Watch the end of the relief valve dischargepipe to ensure that the valve does not weep after the line has hadtime to drain. If the valve weeps, lift the lever again to attemptto clean the valve seat. If the valve does not properly seat andcontinues to weep, contact a qualified service technician to inspectthe valve and system.4. If water does not flow from the valve when you completely lift thelever, the valve or discharge line may be blocked. Immediately shutthe boiler down per instructions on page 2 and call a qualifiedservice technician to inspect the valve and system.5. If relief valve seats properly, restore power to the boiler. Observeoperation for five minutes and ensure it operates properly.WARNINGWARNINGThe boiler must be inspected and serviced annually,preferably at the start of the heating season, by a qualifiedservice technician. In addition, the maintenance and care ofthe boiler as outlined in this manual must be performed bythe user/owner to assure maximum efficiency and reliability.Follow the maintenance procedures given throughout thismanual. Failure to perform the service and maintenance orfollow the directions in this manual could damage the boileror system components, resulting in substantial propertydamage, severe personal injury, or death.To prevent the potential of substantial property damage, severepersonal injury, or death, eliminate all the materials listed inTable 6 from the area surrounding the boiler and the vicinity ofthe combustion air intake. If contaminants are found:• Remove products immediately from area.• If contaminants have been there for an extended period,call a qualified service technician to inspect the boiler forpossible damage from acid corrosion.If products cannot be removed, immediately call a qualifiedservice technician to re-pipe the combustion air intake pipingaway from the contaminated areas.Failure to inspect the venting system and have it repairedby a qualified service technician can result in vent systemfailure, causing severe personal injury or death.To avoid water damage or scalding due to relief valveoperation, a discharge line must be connected to thevalve outlet and directed to a safe place of disposal. Thisdischarge line must be installed by a qualified servicetechnician in accordance with the boiler installation manual.The discharge line must be terminated so as to eliminatepossibility of severe burns or property damage should thevalve discharge.DANGERDANGERCheck the Condensate Drain System1. While the boiler is running, check the discharge end of thecondensate drain tubing. Ensure no flue gas is leaking from thecondensate drain tubing by holding your fingers near the opening.2. If you notice flue gas leaking from the opening, this indicates adry condensate drain trap. If problem persists, contact a qualifiedservice technician to inspect the boiler and condensate line andrefill the condensate trap.
