I hope you can help. In the picture you can see that the glass needs cleaning. I have done the before but, for the life of me I can't remember how I got it apart. I do have the manual for my RHE32 unit. I'm able to remove the top louver. I'm having problems in removing the cast front section to clean the glass. I have looked and looked and just can't find where it screws togeather. The manual doesn't seem to be much help for me. I give up......where are They. Thanks for your help Jim
