code.
Preheat grill with both main burners on high
for 10 to 15 minutes.
Ensure sear plates are installed with the holes
towards the front and the slots on the bottom.

shutter slightly according to combustion air
adjustment instructions. (This must be done
by a qualified gas installer.)
Close air shutter slightly according to
combustion air adjustment instructions. (This
