Open the cold water supply valve to the boiler. b. Check for system leaks. c. Close the weighted check valve on the boiler return piping of the BOILER MATE™ d. Open the drain valve on the boiler return line to release entrapped system air. e. Close the drain valve f. Open the weighted check valve. C. ELECTRICAL WIRING All wiring must be in accordance with local codes, regulations, and ordinances or, in the absence of such codes, the National Electrical Code ANSI/NFPA No. 70, latest edition. The BOILER MATE™ thermostat can be used for either 24 or 120V AC. The thermostat is packaged separately and is installed by sliding the capillary tube into the thermostat well. SEPARATE CIRCULATOR I. BOILER MATE™ as Separate Zone - Non-Priority A. Use of separate BOILER MATE™ ZONE CIRCULATOR Step 1 -Disconnect electrical power. a. Turn off the boiler service switch. b. Turn off the safety switch (if separate from the service switch). c. Switch off the branch circuit breaker. Step 2 - Remove electrical box cover on Thermostat. Step 3 - Wire BOILER MATE™ using Schematic #1 or #2. a. Install BX connector. b. Insert outside wiring to BOILER MATE™ through electrical conduit opening on thermostat. c. Complete exterior electrical wiring per Schematic #1 or #2. Step 4 - Turn boiler low-limit control (it is part of the boiler control) to the off position. Note: Some boilers require minimum setting of low limit. SEPARATE CIRCULATOR Step 5 - Adjust boiler high-limit control to the desired setting. In most cases 180° F to 200° F is acceptable. Step 6 - Re-assemble electrical box cover. Step 7 - Re-connect electrical power. B. Use of only the heating system circulator. When wiring a separate zone valve, follow all steps in 1A except for Step 3c. Use Schematic #3(A, B or C) depending upon the type of zone valve. (Zone valve sizing per pg. 5) II. BOILER MATE™ - Priority Wiring Hot Water Before Space Heating A. Use of separate BOILER MATE™ zone. A DPDT relay is to be used. Refer to Schematic #4. Step 1 - Disconnect electrical power. a. Turn off the boiler service switch. b. Turn off the safety switch (if separate from Electrocution hazard. First dis-connect all electrical power before doing any electrical work. Electrocution hazard. The BOILER MATE™ must be electrically grounded. Electrical supply must come from the boiler side of boiler’s emergency shut-off switch in order to prevent unsafe boiler operation. -8 the service switch). c. Switch off the branch circuit breaker. Step 2 - Remove electrical box cover. Step 3 - Remove existing wire from boiler aquastat terminal C1 and connect to terminal #2 on DPDT relay. Step 4 - Install wire from DPDT relay terminal #1 to boiler aquastat terminal C1. Step 5 - Connect terminals of 4 and 6 of DPDT relay "TT" terminals of boiler aquastat relay. Step 6 - Connect BOILER MATE™ thermostat to L1, BOILER MATE™ and DPDT relay as shown in Schematic #4. Step 7 - Connect L2 to BOILER MATE™ circulator and DPDT relay as shown in Schematic #4. B. Use only the heating system circulator. When wiring a separate, full-flow 3-way zone valve, follow steps in 1B. above. Note: Priority comes from the valve operation and not the wiring. SEPARATE CIRCULATOR D. POST-INSTALLATION and START-UP CHECKLIST After the BOILER MATE™ has been plumbed and wired, it is now ready to be set for automatic operation. Turn on the boiler and safety switches. TEMPERATURE ADJUSTMENT PAINFUL SCALDING WITH POSSIBLE SERIOUS AND PERMANENT INJURY CAN OCCUR IF THE TEMPERATURE IS SET TOO HIGH OR THE THERMOSTAT IS NOT FUNCTIONING PROPERLY. The thermostat controls the maximum water temperature in the BOILER MATE™. If set too high, the resulting hot water can cause painful scalding with possible serious and permanent injury. The temperature at which this occurs varies with a person’s age and the length of time in contact with the water. The slower response time of infants, aged or handicapped persons increases the hazard to them. It is recommended that the temperature control be set for the lowest temperature which satisfies your hot water needs. This will also provide the lowest operating costs. In conjunction with a Consumer Product Safety Commission recommendation, an initial setting of 120° F is recommended. This may or may not be suitable for your needs. Check the temperature at a hot water faucet soon after the burner has completed the first heating. Adjust as needed. Note that adjusting to a lower setting will not have an immediate effect. The stored hot water will first have to be used. Additional checks of the water temperature should follow completion of a cycle. Further adjustments may be necessary as you use your BOILER MATE™ and water piping system. NOTE: VALVES FOR REDUCING POINT OF USE TEMPERATURE BY MIXING COLD AND HOT WATER ARE AVAILABLE. CONSULT A LICENSED PLUMBER OR THE LOCAL PLUMBING AUTHORITY. ZONE VALVES - SCHEMATIC 3 3-WIRE ZONE VALVES 4-WIRE ZONE VALVES PRIORITY W/CIRCULATORS - SCHEMATIC 4 -9 -10- 6. OPERATION/MAINTENANCE. F...
