ODS/pilot.  This  can  damage
ODS/pilot  unit.

When  ignitor  button  is  pressed  and
control knob is pressed in and turned to
the PILOT position, there  is  no  spark
at  ODS/pilot.

ODS/pilot    lights   but flame   goes out
when   control   knob is released.

When  ignitor  button  is  pressed and
control knob is press in and turned to
the PILOT position, there  is  a spark
at  ODS/pilot  but  no ignition.

1.    Ignitor electrode is positioned
        wrong.
2.    Ignitor electrode is broken.
3.    Ignitor electrode is not connected
        to ignitor cable.
4.    Ignitor cable  pinched  or wet.

5.    Broken ignitor cable.
6.    Bad piezo ignitor.

     problem  could  be  caused  by
       one  or  both  of  the  following:
       A)    Low   gas  pressure
       B)   Dirty     or   partially  clogged
             ODS/ pilot
6.    Thermocouple   damaged.
7.    Control valve   damaged.

1.   Replace ignitor.

2.   Replace ignitor.
3.   Reconnect ignitor cable.

4.   Free  ignitor  cable  if  pinched  by
