embers.

Helpful Hints
It is a good idea to replace all light bulbs at one time if they are close to
the end of their rated life. Group replacement will reduce the number
of times you need to open the unit to replace light bulbs.

Lift the back end of the top to clear the brackets and pull back. Lift

Caution should be taken as the top mounting brackets may
scratch the finish.
2. Remove the burnt bulb by pushing in and turning counter-clockwise.
3. Replace the upper light bulb.
4. Reassemble in the reverse order as above.
