Steam Caution

 Hi Dave,
              Thank's for your post.
To reinforce the caution,  this happened to an experienced technician, who
knew how to get himself out of trouble, and did not leave the customer or
mfg holding the bag.  I have had similar experiences with the steam kettle
approach, untill I mastered the technique.
