pressure to equalize. See lighting instructions.
Pipe must be sized according to installation 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. See
assembly instructions.
Preheat grill with both main burners on high for 10

maintenance instructions. Open air 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 must be done by
a qualified gas installer.)

terminal on the back of the igniter. Check that the
lead wires from the module to the ignition switch (if
equipped) are firmly pushed onto their respective

by hardened grease, which dries into paint-like
shards, that flake off. Regular cleaning will prevent
this. See cleaning instructions.
