I. General Information WARNING Improper installation, adjustment, alteration, service or maintenance can cause property damage, personal injury or loss of life. Read and understand the entire manual before attempting installation, start-up operation, or service. Installation and service must be performed only by an experienced, skilled installer or service agency. Installation is not complete unless a pressure and temperature relief valve is installed into the side of the water heater.

CAUTION The heat transfer medium must be water or other non-toxic fluid having a toxicity rating or class of 1, as listed in clinical Toxicology of Commercial Products, 5th edition. The pressure of the heat transfer medium must be limited to a maximum of 30 psig by an approved safety or relief valve. NOTICE This w ater heater has a limited warranty, a copy of w hich is printed on the back of this manual.
during simultaneous space and domestic hot water heating operations, depending on such factors as boiler output, boiler over sizing, number of space heating zones calling for heat and ratio of domestic hot water load to space heating load. Select a circulator which will provide at least the minimum flow rate at combined pressure drop. B. System Zone Control The AllianceTM water heater must be installed as a zone separate from the space heating system.
inlet and outlet tappings. cool to room temperature, or if tank is drained without opening a hot water faucet. A Watts® Model No. N36 is an appropriate vacuum relief valve. 4. Thermal Expansion Tank If water heater is installed in a closed water supply system, such as one having a back-flow preventer in the cold water line, provide thermal expansion control. Contact the water supplier or local plumbing inspector for additional information.
III. Piping 3. Pipe relief valve discharge to floor. A. Drain domestic water system. 4. Connect from supply union to hot water supply system using vacuum breaker, shut-off valve, and heat trap (to prevent thermal siphoning during nondraw periods). 1. Shut off cold water supply at main shut-off valve. 2. Open one or more system faucets to relieve pressure. Open system drain valve, leaving faucets open to relieve vacuum. D. Connect cold water supply piping (see Figure 2). 3.
4. Purge air from domestic water system. Allow water to run so the tank is thoroughly purged of any debris. Run water long enough so that a minimum of five (5) volume changes of the tank are accomplished. Close faucets. Reinstall screens. 1. Determine where in the boiler and space heating piping system the Alliance™ connections should be made by identifying the type of system from Figures 3 thru 6. 2.
G. Connect water boiler supply piping (See Figures 3 thru 6). Figure 3: Water Boiler Piping with Zone Valves and a Boiler Bypass Figure 4: Water Boiler Piping with Zone Circulators and a Boiler Bypass 10 1. For a space heating system that utilizes ZONE VALVES AND A BOILER BYPASS, refer to Figure 3. The Alliance™ connection labeled "BOILER SUPPLY" should be piped to the boiler supply piping as close to the boiler as possible and especially before the bypass piping.
3. For a space heating system that utilizes ZONE VALVES WITHOUT A BOILER BYPASS, refer to Figure 5. The Alliance™ connection labeled "BOILER SUPPLY" should be piped to the boiler supply piping after the air purger and before the space heating circulator. Mount the water heater circulator as close as possible to the water heater making sure the flow arrow points toward the water heater. The use of a shut-off valve is recommended for future service convenience.
valve is recommended for future service convenience. The use of a flow control or check valve is required to prevent back flow through the water heater during operation of the space heating system. H. Connect steam boiler piping (See Figures 7 thru 10). 1. Burnham V-7 Series steam boiler (Refer to Figure 7). a. For satisfactory supply of hot water, the V-7 steam boiler must be equipped with a special tapped rear heater coil cover plate contained in both of the following kits: c.
Figure 8 3. Typical steam boiler with connections available below the water line (Refer to Figure 9). boiler section furthest away from the return tapping to prevent short circuiting in the boiler. This tapping should be high enough to provide hot water but must be below the lowest permissible water level. The water heater circulator should be floor mounted with full size (1" minimum) piping from the boiler and no flow restrictions in this piping.
Figure 10 4. Steam boiler without hot water connections available below the water line (Refer to Figure 10). I. Fill boiler system. 1. On new boiler installations, do not purge the boiler or space heating system through the water heater. During any boiler or space heating system flushing, cleaning, or purging, the water heater should be isolated to avoid possible attack on the copper coil by chemical additives. a.
IV. Electrical 1. Install electric wiring in accordance with National Electrical Code or the Canadian Electrical Code and local regulations. See Figure 11 for the wiring diagram and the boiler's Installation manual. 2. The Alliance™ models contain an aquastat assembly and will require an installer supplied double pole, single throw (DPST) relay with a normally open (NO) contact, a normally closed (NC) contact, and a 120 volt coil for priority domestic water. A Honeywell R4222D1013 is an appropriate relay.
V. Operation A. System Start-Up 2. For the most energy efficient operation, adjust aquastat for the minimum water temperature necessary to meet domestic hot water needs. 1. Follow boiler installation instructions to place boiler in operation. 2. Turn aquastat dial clockwise to desired setting. a. An initial setting of 120°F is recommended. b. Turning the knob clockwise from "100" position will cause an audible click indicating the desired temperature is higher than the current tank water temperature. B.
VI. Service Instructions A. The Alliance™ is intended to provide a service life of 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. many years. Components that require service, however, may be subject to failure.
VII. Trouble Shooting PROBLEM No hot water at faucet CAUSE SOLUTION 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.
