Safety Precautions

A tank of approximately 12 inches in diameter by 18­1/2 inches high is the maximum size LP gas tank to
use. You must use an OPD gas tank which offers

an Overfill Prevention Device.

This safety feature prevents the tank from being
overfilled which can cause malfunction of the LP gas
tank, regulator and/or grill.

The LP gas tank must be constructed and marked in
accordance with specifications of the U.S. Dept. of
Transportation (DOT). In Canada, the LP gas tank
must meet the National Standard of Canada ,Can
CSA –B339 , Cylinders , spheres and Tubes for
Transportation of Dangerous Goods and
Commission .

1. The LP gas tank must have a shutoff valve,
terminating in an LP gas supply tank valve outlet,
that is compatible with a Type 1 tank connection
device. The LP gas tank must also have a safety
relief device that has a direct connection with the
vapor space of the tank.

2. The tank supply system must be arranged for
vapor withdraw.

3. The LP gas tank used must have a collar to
protect the tank valve.

Proper Placement and Clearance of Grill
Never use your gas grill in a garage, porch, shed,

breezeway or any other enclosed area. Your gas grill
is to be used outdoors only, at least 24 inches from
the back and side of any combustible surface. Your
gas grill should not be used under overhead
combustible construction . Do not obstruct the flow of
ventilation air around the gas grill housing.

• Do not install this outdoor gas grill in or on
recreational vehicles or boats

• Keep outdoor gas grill area clear and free from
combustible materials, gasoline and other flammable
vapors and liquids

• Do not obstruct the flow of combustion and
ventilation air. Check for this ea ch time prior t o usi ng
grill.

• Never connect an unregulated LP gas tank to your
gas grill. The gas regulator assembly supplied with
your gas grill is adjusted to have an outlet pressure
of 11” water column (W.C.) for connection to an LP
gas tank.

• Only use the regulator and the hose assembly
supplied with your gas grill. Replacement regulators
and hose assemblies must be those specified in this
manual.

• Have your LP gas tank filled by a reputable

propane gas dealer and visually inspected and re­qualified at each filling.

• Do not store a spare LP gas tank under or

• near this appliance.

• Never fill the tank beyond 80 percent full . If this

information is not followed exactly a fire causing
death or serious injury may occur.

• Always keep LP gas tanks in an upright position.

• Do not store (or) or use gasoline or other

flammable vapors and liquids in the vicinity of this
gas grill.

• Do not subject the LP gas tank to excessive heat.

• Never store an LP gas tank indoors. If you store

your gas grill in the garage or other indoor
location, always disconnect the LP gas tank first
and store it safely outside.

• Place dust cap on cylinder valve outlet whenever

the cylinder is not in use. Only install the type of
dust cap on the cylinder valve outlet that is
provided with the cylinder valve. Other types of
caps or plugs may result in leakage of propane.

• LP gas tanks must be stored outdoors in a well-

ventilated area and out of reach of children.
Disconnected LP gas tanks must not be stored in
a building, garage or any other enclosed area.

• When your gas grill is not in use the gas must be

turned off at the LP gas tank.

• The regulator and hose assembly must be

inspected before each use of the grill. If there is
excessive abrasion or wear or if the hose is cut, it
must be replaced prior to the grill being used
again.

• Keep the gas regulator hose away from hot grill

surfaces and dripping grease. Avoid unnecessary
twisting of hose. Visually inspect the hose prior to
each use for cuts, cracks, excessive wear or
other damage. If the hose appears damaged do
not use the gas grill. Call 1-800-913-8999 for

WARNING

!

A strong gas smell, or the hissing sound of gas
indicates a serious problem with your gas grill or
the LP gas tank. Failure to immediately follow the
steps listed below could result in a fire or
explosion that could cause serious bodily injury,
death, or property damage.

• Shut off gas supply to the gas grill.

• Turn the control knobs to OFF position.

• Put out any flame with a proper fire extinguisher.

• Open Grill Lid.

• Get away from the LP gas tank.

• Do not try to fix the problem yourself.

• If odor continues or you have a fire you can not
extinguish, call your fire department. Do not call
near the LP gas tank because your telephone is
a form of electrical device and could create a
spark resulting in fire and/or explosion.

NOTE: The normal flow of gas through the
regulator and hose assembly can create a
humming noise. A low volume of noise is
perfectly normal and will not interfere with
operation of the grill. If humming noise is loud
and excessive you may need to purge air from
the gas line or reset the regulator excess gas
flow device. This purging procedure should be
done every time a new LP gas tank is
connected to your grill. For help with this
procedure refer to page 14, Item 4 of “If Grill Still
Fails To Light”, or call the Customer Se rvice
Helpline 8 AM to 5 PM PST at: 1-800-913-8999

Burner Flame Check

Visually check the burner flames prior to each use. The
flames should look like picture, if they do not, refer to the
cleaning burner tubes and ports, see page 15 of this
manual.

CAUTION: Beware of Flash-Back

CAUTION: Spiders and small insects occasionally

spin webs or make nests in the grill burner tubes
during transit and warehousing. These webs can lead
to gas flow obstruction which could result in a fire in
and around burner tubes. This type of fire is known as
“FLASH-BACK” and can cause serious damage to
your grill and create an unsafe operating condition for
the user.

Although an obstructed burner tube is not the only
cause of “FLASH-BACK”, it is the most common
cause.

To reduce the chance of “FLASH-BACK”, you must
clean the burner tubes before assembling your grill,
and at least once a month in late summer or early fall
when spiders are most active. Also perform this
burner tube cleaning procedure if your grill has not
been used for an extended period of time.

See Cleaning Burner Tubes and Ports on page # 15
