Disconnect power at the breaker. Remove two screws from one end of trim and slide trim off opposite end. Remove grill 
by grasping it in the middle, flex grill up and lift it off. Unscrew and remove both end reflectors. Unhook element clips 
at each end of the heater and remove nuts from end of element to remove the existing quartz tube. Carefully install the 
new element. Remove one nut from end of the new element. Install wire by sliding high temperature ring terminal onto 
element screw and replace nut. Use a thin 11/32" wrench to hold inside nut. Nuts must make a tight connection. Close 
element clips over tube and reinstall end reflectors, and snap protective grill back in, then reinstall trim.

NOTE:  Hold ceramic element firmly while 

tightening nut to prevent damage to 
element. Nut should be tightened snug.  
A loose connection can cause the  
element to short or fail prematurely.
