- Page 4 Is the water heater undersized for the application? (Non-Warranty) - There are many methods of sizing various applications, i.e. ASHRAE sizing tables, or ASPE domestic water heating design manual, re-confirm the water demand required for the application. - Re-confirm the flow rates of the fixtures. Was the tank sized for shower heads at 2.0 gpm, when the actual heads are 5.0 gpm? Use a bucket and a stopwatch to determine fixture flow rates.
- Page 5 - Is the circulator between the boiler and the water heater properly sized to provide adequate flow for maximum BTU transfer? 3/4" 1" 1 1/4" 1 1/2" 2" Check component parts - Is the domestic water thermostat functioning properly? With a electrical voltmeter check for continuity between terminals C and 1 on the snap-set connection.
- Page 6 - What is the location of the thermostat bulb? A bulb inserted completely at the bottom of the drywell will initiate a quicker response for a call for heat. This is typically the position of the bulb required for applications in which there are large draws of domestic water. - Remove and examine the dip tube located in the cold water inlet.
- Page 7 Excessive water temperature is usually the result of stacking within the water heater. Stacking is the occurrence of various water temperatures layering within the water heater with the hottest water in the uppermost layer. This layering or stacking effect typically occurs during small draws of hot water (typically less than 25% of the storage capacity) which are long enough to create a call for heat on the thermostat, but are short enough not to deplete the stored energy within the tank.
- Page 8 - If possible, isolate the Plus tank from the boiler system for an extended period of time. Observe the boiler system pressure during that time. * This may be a manufacturing defect. Please initiate a warranty claim with Weil-McLain noting the reason code listed.
- Page 9 Is there a thermal expansion tank installed on the domestic supply piping and is it properly sized? (Non-Warranty) - A thermal expansion tank is required if the domestic supply piping includes a backflow preventer or pressure reducing valve. - Ensure the potable water expansion tank is properly sized according to the water heater volume and supply pressure.
- Page 10 - To replace the drywell use the Replacement Kit. (See chart on Page 15, 17, 19 or 21) - Apply sealant (i.e. Leaklok or Loctite) completely around threads in all applications. * This may be a manufacturing defect. Please initiate a warranty claim with Weil-McLain noting the reason code listed.
- Page 11 - To replace the drywell use the Replacement Kit. (See chart on Page 15, 17, 19 or 21) - Apply sealant (i.e. Leaklok or Loctite) completely around threads in all applications. * This may be a manufacturing defect. Please initiate a warranty claim with Weil-McLain noting the reason code listed.
- Page 12 The hot water smells like “rotten eggs” (Non-Warranty) The most common cause of water to smell like “rotten eggs” is a non-toxic sulfate reducing bacteria. The bacteria usually enters into the water system through a break in the supply piping or during construction/maintenance of the supply piping.
- Page 13 Hot water from the faucet appears milky (Non-Warranty) When water is initially drawn from the faucet it appears to be milky or cloudy, but it becomes clear after the water is allow to stand for several minutes. This is usually an indication that the water contains high levels of soluble gases such as oxygen, chlorine, carbon dioxide, hydrogen sulfide or others.
- Page 14 Discolored water from the hot water faucet (Non-Warranty) The water from the hot water faucet appears discolored, either rusty, brown, black or yellow. Because the inner tank is stainless steel, which by its nature is resistant to corrosion, the problem is not tank related. The problem is usually a non-toxic iron reducing bacteria that is commonly found in soil, well water, water treatment plants and piping systems.
