off position when the tank valve is turned
on. Turn tank on slowly to allow 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

This is not a defect. It is caused by internal
vibrations in the regulator and does not
affect the performance or safety of the
gas grill. Humming regulators will not be
replaced.

and hood is porcelain, and will not peel.
The peeling is caused by hardened grease,
which dries into paint-like shards, that
flake off. Regular cleaning will prevent this.
