3. Inspect the water and gas lines to verify they are free from leaks. Call the service technician to make repairs if required. CaUTiOn Water leaks can cause severe corrosion damage to the boiler or other system components. immediately repair any leaks found. C. Annual Inspections and Service: In addition to the inspections listed above the following should be performed by a service technician once every year. 1. If equipped, test the low water cutoff by pressing the “Test” button located at its end. The yellow light should come on and “E12” should flash on the display. Push the reset button on the display to restore normal operation. If the yellow light does not come on, determine why the low water cutoff is not working properly. 2. Follow the procedure for turning the boiler off found in the Alpine™ Series Lighting and Operating Instructions. 8 3. Inspect the wiring to verify the conductors are in good condition and attached securely. CaUTiOn Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing. 4. Remove the ignition electrode and inspect it for oxides. Clean the oxides from the electrode with steel wool. Do not use sandpaper for the cleaning. Inspect the ceramic insulator for cracks and replace the ignitor assembly if necessary. Check the ignitor electrode spacing gap. Refer to Figure 56 “Ignitor Electrode Gap” for details. Figure 56: ignitor Electrode gap 5. Remove the fan/gas valve assembly from the burner hood. Inspect for lint and dust. If significant lint and dust are found, disassemble the fan/gas valve assembly to expose the swirlplate and fan inlet (see the exploded diagram in the parts list at the back of this manual). Vacuum these parts as required, being careful not to damage the vanes on the swirlplate. 6. Remove the burner hood to access the burner and the combustion chamber. 7. Remove the burner and vacuum any dust or lint from the burner. If the burner shows signs of deterioration or corrosion, replace it immediately. Inspect the burner gasket and replace, if necessary. 8. Inspect the heat exchanger, clean and vacuum any debris found on the surfaces. A soft nylon brush must be used for cleaning. Remove insulation disc and clean the surfaces by flushing with clean water. Drain and flush the inside of the heat exchanger and condensate collector. Do not use any cleaning agents or solvents. Re-install insulation disc. 9. Inspect the condensate trap to verify it is open and free from debris. Inspect condensate line integrity between boiler and condensate neutralizer (if used) and condensate neutralizer and the drain. Clean/ repair if needed. If the condensate neutralizer is used, check pH before and after the neutralizer to determine neutralizing effectiveness. Replace limestone chips and clean out the neutralizer if needed. 10. Reinstall the burner, burner hood and fan/gas valve assembly. 11. Reconnect any wiring which has been disconnected. 12. Inspect the heating system and correct any other deficiencies prior to restarting the boiler. 13. Follow Section XI System Start-up before leaving installation. 14. Perform the combustion test outlined in Section XI System Start-up. 15. Verify that the system PH is between 8.2 and 9.5/. 16. Check for vent terminal obstructions and clean as necessary. D. Recommended Heating System Water Treatment Products: 1. System Cleaning and Conditioning: a. The following heating system water treatment products are recommended for an initial existing heating system sludge removal, initial boiler cleaning from copper dust, flux residue and any boiler debris and for preventive treatment as corrosion/scale inhibitors: i. Fernox™ Restorer (universal cleaner, sludge remover, scale remover, flux residue/debris remover, corrosion inhibitor) ii. Fernox™ Protector (Alphi 11, CH#, Copal) (sludge remover, corrosion inhibitor) Follow manufacturer application procedure for proper heating system/boiler cleaning and preventive treatment. Above referenced products are available from Cookson Electronics Company, 4100 Sixth Avenue, Altoona, PA 16602, Tel: (814) 946-1611 and/or selected HVAC distributors. Contact US Boiler for specific details. iii. Equivalent system water treatment products may be used in lieu of products referenced above. 2. System Freeze Protection: a. The following heating system freeze protection products are recommended for Alpine boilers: i. Fernox™ Protector Alphi 11 (combined antifreeze and inhibitor). Follow manufacturer application procedure to insure proper antifreeze concentration and inhibitor level. Above referenced product is available from Cookson Electronics Company, 4100 Sixth Avenue, Altoona, PA 16602, Tel: (814) 9461611 and/or selected HVAC distributors. Contact US Boiler for specific details. b. Equivalent system freeze protection products may be used in lieu of product referenced above. In general, freeze protection for new or existing s...
