• Tear the corrugated as shown in Figure 12.6. The
corrugated must be separatewd along the entire top edge
of the protector.
• Slide the screen protector off the screen as shown in
Figure 12.7.
• Rockwool is shipped with this gas appliance.
• Place a small amount of 1/2 in. diameter pieces (dime-size)
rockwool on the burner pan so that the rockwool touches,
but does not cover, the holes in the burner pan (refer
to Figure 12.5). This will provide the “glowing embers”
look.
• It is not necessary to use the entire bag. Save the
remaining rockwool for future use.
