2. Visually inspect venting system for proper func-tion, deterioration or leakage. Ensure thatcondensate drain is inspected and ensure thatcondensate is being directed to appropriate con-densate management system or drain, as requiredby local codes.3. Check that area is free from combustible materi-als, gasoline, and other flammable vapors andliquids.4. Check for and remove any obstruction to the flowof combustion or ventilation air to heater.5. Follow pre-start-up check in the Start-up section.6. Visually inspect burner flame. It should be lightblue at full input. Remove and visually inspect hotsurface igniter and sensor for damage, cracking ordebris build-up.7. Check operation of safety devices. Refer to manu-facturers’ instructions.8. Follow oil-lubricating instructions on pump (if re-quired). Over-oiling will damage pump.Water-lubricated circulators do not need oiling.9. To avoid potential of severe burn, DO NOT RESTHANDS ON OR GRASP PIPES. Use a light touch;return piping will heat up quickly.10. Check blower and blower motor11. Check for piping leaks around pumps, relief valvesand other fittings. Repair, if found. DO NOT usepetroleum-based stop-leak.12. Check the fault history and reset as necessary.Periodically1. Check relief valve(s). Refer to manufacturer’sinstructions on valve.2. Test low water cut-off (if equipped). Refer to manu-facturer’s instructions.3. Reset fault history after any testing.Preventive MaintenanceScheduleThe following procedures are recommended and aregood practice for all XTherm installations.Daily1. Check gauges, monitors and indicators.2. Check instrument and equipment settings. (See“Post Start-Up Check” on page 46.)3. Check burner flame. (Should see light blue flameat full input rate).WeeklyFor low-pressure heaters, test low-water cut-offdevice. (With heater in pre-purge, depress the lowwater cut-off test button. Appliance should shut-offand ignition fault light should come on. Depress resetbutton on front of heater control panel to reset).Monthly1. Check flue, vent, stack, or outlet dampers.2. Test blower air pressure. (See “Blower Check” onpage 44.)3. Test high and low gas pressure interlocks (ifequipped). (See “Safety Inspection” on page 45.)4. Check tracking pressure (see “Blower Check” stepnumber 2 on page 44).5. Reset fault history after any testing.Semi-Annually1. Recalibrate all indicating and recording gauges.2. Check flame failure detection system components.3. Check firing rate control by checking the manifoldpressure. (See “Manifold Check” on page 44.)4. Check piping and wiring of all interlocks and shut-off valves.Annually1. Test flame failure detection system and pilot turn-down.2. Test high limit and operating temperature. (See“Post Start-Up Check,” page 46.)3. Check flame sensor.California Hot Water Supply, Inc.(800) 249-724450
