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 vo ltage 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.
