STEP 4
Using the 130g bag of crystals supplied, first place some
crystals into the three clear fuel bed circles created in step 3,
fill the exposed fuel bed area fully with crystals as shown. The
remainder of the crystals can then be placed anywhere else on
the fuel bed. These crystals are used to generate the illusion of
hot ash and fire embers. We recommend using the entire bag of
crystals to achieve optimal effect.
Now you are ready to switch on the product to enjoy the
beautiful Opti-flame 3D flame.
