A. General Guidelines1. A thorough and complete water heater inspectionand check must be conducted a minimum of one(1) time per year.2. Follow any checks and/or inspections that maybe required as specified in the componentmanufacturer's instruction manuals.3. Repair or replace any defective componentsimmediately.4. The following service procedures are required forproper and safe water heater operation.B. Daily Water Heater Inspection & Check1. Inspect the area to assure proper clearance fromcombustible materials, gasoline, and otherflammable vapors, and liquids.2. Observe burner color. See FIgure 26.3. Check flame control for proper operation andshutdown.4. Check vent and air intake piping for anyobstructions.5. Check for any water leaks.6. Check for any gas leaks.7. Check condensate drains for any obstructions.8. Clean any debris or trash from area.9. Check the low draft, fan, air pressure, anddamper position interlocks, according to themanufacturer’s instructions, if so equiped.10. Check gauges, monitors, and indicators to assurethey are functioning properly.11. Clean terminal screens. Terminals must be freeof obstruction, undamaged, with screenssecurely in place.12. Log that the above mainenance was completedin an appliance log. Maintain log near appliancelocation.C. Weekly Water Heater Inspection & Check1. Check flame strength for both pilot and mainflames; log.2. Check igniter.3. Check operation of the flame failure detectionsystem for both pilot and mainflame.4. Check firing rate control for proper operation.5. Check pilot and main fuel valves:a) open limit switch and make aural and visualinspection; check valve position indicators andfuel meters, if provided.6. Check the low water cutoff device & alarmaccording to the manufacturer’s instructions.427. Terminal Wall thimbles (if used) must beweathertight8. Horizontal vent tee drain or vertical vent teedrain (if used) must have minimum 6 inch trapand allow condensate to flow freely. To Clean:i. Disconnect drain tube from drain fitting.ii. Flush drain tube with water. Fill trap withwater.iii. Securely fasten drain tube to drain fitting,providing gas-tight and watertight seal.9. If pipe must be disassembled for removal ofobstructions or resealing of joint, see SectionIII, Paragraph B.10. Inspect condensate trap water level. If low, addwater to bring level to trap discharge.11. Ensure condensate can flow freely to drain.D. Monthly Safety and Operating Control Checks1. Check proper operation of all water heatersystem safety and operating controls includingflame safeguard.2. Check proper operation of safety relief valve.3. Check condition of water (pH, alkalinity,hardness). Correct water condition as needed.4. Check carbon monoxide level in flue products.5. Check venting/air intake and condensate draintubes for obstructions.6. Repair or replace any inoperative or damagedcomponents.7. Low water cutoff, float type (If so equiped).a) Monthly Blowoff. During the heating season,if an external float type low water cutoffis above the water heater, the blow off valveshould be opened once a month (use greaterfrequency where conditions warrant), to flush outthe sediment chamber so the device will be freeto function properly.8. Inspect and replace air filter as needed.9. Check high and low gas pressure switchinterlocks.10. Log service procedure in appliance log.E. Semi-Annual “Tune-up”1. Inspect condensate drain tubes for deterioration,cracking, etc.2. Inspect air intake and exhaust pipes for leaks,deterioration, scale, etc.3. Measure fuel input, oxygen and carbonmonoxide in flue products.
