Normally open contacts open, stopping boiler operation. Domestic hot water priority only: normally closed contacts close, returning boiler control to space heating. D. b. Adjusting to a higher temperature may not immediately affect water temperature. If a heat- up cycle begins, go to step 3. If a heat-up cycle does not begin, draw sufficient water or allow the water heater to sit until a heat-up cycle is initiated. Repeat step 3. To Shut-off Water Heater C. Water Temperature Adjustment 1. The aquastat controls the maximum water temperature in the tank. It's differential is fixed at 5°F. It's maximum setting is 160°F. 1. Turn power off to the Alliance. 2. Follow boiler operating instructions to turn off boiler. WARNING Never operate water heater with temperatures in excess of 200°F. Severely reduced water heater life will result. 16 VI. Service Instructions A. The Alliance™ is intended to provide a service life of many years. Components that require service, however, may be subject to failure. Failure to use the correct procedures or parts in these circumstances may make the water heater unsafe. The owner should arrange to have the following inspections and simple maintenance procedures performed by qualified service personnel at the frequencies suggested. 1. Boiler and Domestic Water Piping (Annual) Check all piping for signs of leakage at joints, unions, and shut-off valves. Repair as needed. 2. Temperature-Pressure Relief Valve (Annual) Follow instructions packed with valve. 3. Sediment (Annual, but harsh water quality may dictate more frequent service) Depending on water conditions, a varying amount of sediment may collect in the tank. Levels requiring service are indicated by a small temperature difference in the supply and return lines. (See also "Scale" below.) Repeated flushing usually clears such material. As a preventive measure, water should be drawn from the tank at the drain valve until it runs clear. 4. Scale (Annual) Hard water may cause scale to build-up on the outside of the heat exchanger coil. A water softener will prevent this problem. (See also "Sediment" above.) Symptoms would be reduced recovery capacity or reduced temperature differential between boiler supply and return lines. Repeated flushing should resolve the problem. If not, proceed to B. B. Chemical cleaning of heat exchanger coil 1. To avoid water damage to nearby areas in subsequent steps, shut off the cold water supply to the water heater. 2. Make a note of the temperature control setting on the water heater, then turn the unit off. 3. Relieve the water pressure in the tank by opening a hot water faucet. This will reduce the risk of scald injury. 4. Remove the relief valve from the water heater taking care to avoid contact with the hot water which may drain out of the lines leading to the domestic uses. 5. Drain the water heater until the water within the tank is even with the top of the heat exchanger coil. The water heater cover plate should be removed from the tank to view the inside of the tank and assure the coil is just covered with water. 6. Using a funnel, pour one gallon of commercial ice maker cleaning solution into the tank through the cover plate opening. Follow solution manufacturer's instructions, cautions and warnings. 7. Set the water heater's temperature control to its highest setting and operate the system until the control is satisfied. Boiler may cycle on its high limit several times during this period. If the tank temperature setting has not been satisfied after 45 minutes of boiler operation, turn aquastat to the lowest setting to stop boiler operation. 8. Allow heated solution to set in tank for 30 minutes. 9. Drain tank completely using fittings and hose, as required, to reach a floor drain. 10. Fill the water heater's tank with fresh, cold, conditioned water and drain completely at least two (2) times to flush all cleaning solution from the tank. 11. Reinstall the relief valve, cover plate, and piping. 12. Open the cold water supply and fill the tank with water. Then purge air from lines and tank by operating hot and cold water faucets in the house. 13. Return the temperature control to the setting noted in Step 2. C. Alternate heat exchanger coil cleaning methods The chemical cleaning process is most effective if done properly. Other methods may also give satisfactory results including, high velocity water wash using a wand through the cover plate. 17 VII. Trouble Shooting PROBLEM CAUSE SOLUTION No hot water at faucet Boiler does not operate Refer to boiler installation instructions Check main service switch Check fused disconnect Circulator does not operate Check power supply Check shaft coupling Improper aquastat setting or calibration Turn tank aquastat to higher setting Zone valve does not open (if used) Check power supply Electrical problem (relay, wiring, fuse, etc.) Check fuse and replace Check circuit breaker and reset (if applicable) Check power supply Scale build-up If boiler, circulator a...
