Question:
The Regulator and Hose supplied with my gas grill
does not fit the older LP Gas tank I’ve used for
years. Why not?
Answer:
The U.S. Government regulates gas appliances and
LP Gas tanks. When regulations are changed the LP
Gas tank fittings are altered to insure compliance. If
your LP Gas tank does not fit the Regulator and Hose
supplied with your new grill, the tank is outdated and
must be replaced. Note: Effective April 1, 2002 all LP
Gas tanks sold must include an “OPD” Overfill
Prevention Device. The OPD tanks are identified by
their triangular-shaped valve wheel. This internal
device prevents the LP Gas tank from being
overfilled. Tanks without an OPD valve can not be
refilled.
Question:
What type of pipe and fittings will I need to connect
a natural gas grill at my home?
Answer:
Even if your home is plumbed with a natural gas
connection outdoors, there is an additional fitting and
piping required to hook up a natural gas grill. Refer
to the Natural Gas section of this manual for a
diagram of recommended Natural Gas hook-up.
Because each home is unique the type and length of
fittings will vary. This is a technical process that
involves patience and time. The details below will
offer guidance but if you feel uncomfortable with this
procedure you should seek the assistance of a
plumber or gas supply professional.
Gas Line Piping:
If the length of line required does
not exceed 50 feet, use a 5/8" O.D. tube. One size
larger should be used for lengths greater than 50
feet. Gas piping may be copper tubing, type K or L;
polyethylene plastic tube, with a minimum wall
thickness of .062 inch; or standard weight
(schedule 40) steel or wrought iron pipe. Copper
tubing must be tin-lined if the gas contains more
than 0.3 grams of hydrogen sulfide per 100 cubic feet
of gas. Plastic tubing is suitable only for outdoor,
underground use. Gas piping in contact with earth, or
any other material which may corrode the piping,
must be protected against corrosion in an approved
manner. Underground piping must have a minimum
of 18" cover.
Shut Off Valve:
It is
highly recommended
that a Shut
Off Valve be installed at the gas supply source
outdoors. Install at a point after the gas pipe exits the
outside wall and before the Quick Disconnect Hose,
or install it at the point before the gas line piping
enters the ground.
Question:
What causes grill parts to rust and what affect does
it have on my grill?
Answer:
Rusting is a natural oxidation process and may
appear on cast-iron and steel parts. Rust will not
affect the short term performance of your grill.

To slow the rusting process on steel Cooking Grids
(select models) we recommend greasing the Cooking
Grids before and after each cookout. Use a brush to
apply a thin layer of cooking oil or vegetable
shortening onto each Cooking Grid. We do not
suggest spray type oils unless they are specified for
high-temperature cooking. Be sure to coat the entire
cooking surface including edges and any areas with
chipped porcelain.
They all have their advantages. For traditional grilling
and searing meats, cast-iron or steel grids offer better
heat conductivity. To protect against the natural rusting
process, steel or cast-iron cooking grids offer a
porcelain finish which requires routine maintenance to
keep the grids well seasoned.
Stainless steel is popular with those who prefer less
maintenance.
A new innovative solution is available on select
models called Stainless Clad Therma-Core®. This
Cooking Grid combines a heat conducting steel core
with an easy-to-clean stainless outer shell.
All stainless grades are not created equal. The 304
grade, also called 18-8 stainless steel, is prized for its
excellent resistance to rust and corrosion and good
performance at high temperatures, which makes it ideal
for grill construction.
304 grade stainless steel is by far the most popular
stainless steel and contains 18-20% chromium and
8-10% nickel, making it non-magnetic.
Some stainless steel grills are constructed of Type 430
stainless steel which contains 16-18% chromium but
generally less than 1% nickel. It is magnetic with less
corrosion and rust resistance and designed for limited
temperature use. Beware of stainless steel grills that
offer no claim of grade because what looks shiny on the
sales floor could become a problem on your patio.
How can you tell if a product is made of 304 grade
stainless? Take the simple magnet test. If a magnet
sticks to the stainless steel it is 430 grade. If a magnet
does not stick you can trust its 304 grade quality.

Question:
Some stainless steel grills specify 304 grade
construction while others do not mention a grade at
all? What is the difference?
