Notes:
1. All wiring must be installed in accordance with: local, state, provincial and national code requirements per either N.E.C.
in USA or C.S.A. in Canada.
2. If any original equipment wire as supplied with the appliance must be replaced, it must be replaced with wire having same
wire gauge (AWG) and rated for a minimum of 105°C. Exceptions: Replacement high voltage spark lead and ribbon cables
must be purchased from the factory. Use of a non-approved spark lead or ribbon cables can lead to operational problems
which could result in non-repairable damage to the integrated controller or other components.
3. Actual connector block locations may vary from those shown on diagrams. Refer to actual components for proper
connector block locations when using diagrams to troubleshoot unit.
