Smart manual_Smart manual 10/29/14 10:00 AM Page 25 Water Heater Maintenance Maintenance Schedule Annual service by qualified service technician should include the following: Any procedure required by local codes. Check air vent operation. Verify system pressure. Manual air venting procedure may require adding water to bring system up to pressure, typically 12 psig. Manually operate T&P relief valve at least once a year. This will release some hot water.
Smart manual_Smart manual 10/29/14 10:00 AM Page 26 Water Heater Maintenance NOTICE WARNING Do not use automotive, ethylene glycol or petroleum-based antifreeze. Do not use any undiluted antifreeze. This can cause severe personal injury, death or substantial property damage. Prior to draining the inner tank, ensure the following is completed: 1. The snap-set wiring connection at the water heater is disconnected. 2. The DHW system supply isolation valve is closed. WARNING 3.
Smart manual_Smart manual 10/29/14 10:00 AM Page 27 Water Heater Maintenance 5. Apply compressed air at a maximum regulated pressure of 40 psig. 6. When draining is complete, remove the air hose and fittings needed to connect the air hose. Draining Outer (Boiler Water) Tank 1. Disconnect snap set wiring connection at water heater. 2. Close boiler water isolation valves between boiler and water heater. 3. Connect hose to boiler water drain valve at water heater. Open and drain water to a safe place.
