Removal of existing screws
This is the trickiest part of the procedure. The screw heads are very easy to strip.
Hold the vapor cap and enclosed wrench as shown and press the wrench firmly into the screw head while keeping it correctly aligned. Twist the wrench counterclockwise while continuing to press it firmly into the screw head. Remove all screws and plates. The fragile hot plate should be handled carefully.
Clean the cap – Clean using a cotton swab damp with alcohol. Do not soak the cap.
Installing the plates
Install the plates in the order shown. Raised pip on the diffuser should be facing up. Use toothpicks to align the metal parts with the wood frame. Start all 3 screws in the wood frame before tightening any of them. Tighten the screws until they are snug, not tight.
