WIRING CONNECTIONS
ALL ELECTRICAL WORK MUST BE INSTALLED IN ACCORDANCE WITH THE MOST RECENT VERSION OF THE NATIONAL ELECTRICAL CODE/CANADIAN ELECTRICAL CODE AND MUST CONFORM TO LOCAL REGULATIONS.
AN ELECTRICAL GROUND IS REQUIRED TO REDUCE RISK OF ELECTRIC SHOCK OR POSSIBLE ELECTROCUTION. Make the ground connection to the wire provided in the electrical supply junction box on the boiler.
Grounding and all wiring connected to this boiler must conform to the local code authority having jurisdiction or, in the absence of such requirements, with the National Electrical Code, ANSI/NFPA 70 or
The Central Control Board and Ignition Control Boards that make up the control system are
commercial-grade surge protection device.
IF ANY OF THE ORIGINAL WIRE, AS SUPPLIED WITH THE APPLIANCE, MUST BE REPLACED, IT MUST BE REPLACED WITH TYPE 105°C WIRE OR ITS EQUIVALENT.
The Genesis Hot Water Supply Boiler must be connected to a single phase line source that is:
120 volts, 60 Hertz, and 30 Amps.
The system controller, other than the
Refer to the Schematic Diagram (Figure 19) and the Connection Diagram (Figure 20) for wire connections.
Fuse Protection
The 24 VAC circuitry is protected with a 3 amp auto fuse on the ignition control boards and a 5 amp fuse on the Central Control Board. If the fuse opens, a red LED located near the fuse will light (see figures 14 and 15). If the red LED is illuminated, replace the fuse. Repeated failure of the fuse is an indication of possible damage to the ignition control. The 120V circuits of each ignition control module is protected with a 10 amp fuse located inside the control box.
Note: Four extra 3 amp fuses and one 5 amp fuse are supplied with the boiler.
Recommended Replacement fuses:
3 Amp: Littlefuse automotive fuse PN 257003
5 Amp: Bussman Automotive fuse PN ATC5
OPERATION
IMPORTANT
Only qualified personnel shall perform the initial firing of the heater. At this time the user should not hesitate to ask the
Lighting and Operating instructions are included with this manual. By using these instructions, the user may be able to make minor operational adjustments and save unnecessary service calls. However the user should not attempt repairs, but should contact a service technician or gas supplier.
GENERAL
Never operate the boiler without first making sure the boiler and system are filled with water, in addition:
For hot water supply installations:
•Make sure a temperature and pressure relief valve is installed at the boiler and, if used, the storage tank. Also check for leaks.
For heating boiler installations:
•Make sure that the boiler and system have been purged of air and checked for leaks.
Also be sure to check the gas piping for leaks before beginning the initial firing of the boiler.
FILLING AND PURGING FOR HEATING
BOILER INSTALLATION
1.Fast fill system through bypass until pressure approaches desired system pressure. Close bypass valve and permit pressure to be established by the pressure reducing valve.
2.Vent all high points in system to purge system of air.
Provisions should be made to permit manual venting of radiators or convectors.
FILLING FOR HOT WATER SUPPLY BOILER INSTALLATION
1.Close the systems drain valve by turning handle clockwise.
2.Open a nearby hot water faucet to permit the air in the system to escape.
3.Fully open the cold water inlet pipe valve allowing the heater and piping to be filled.
4.Close the hot water faucet as water starts to flow.
5.The heater is ready to be operated.
