TESTED IN ACCORDANCE WITH ANS Z21.58a CSA

1.6a-2008 STANDARD FOR OUTDOOR COOKING GAS

APPLIANCE. THIS GRILL IS FOR OUTDOOR USE ONLY.

Grill Installation Codes

Check your local building codes for the proper method of
installation. in the absence of local codes, this unit should
be installed in accordance with the National Fuel Gas
Code ,ANSI Z223.1/NFPA 54,Storage and Handling of
Liquefied Petroleum Gases, ANSI /NFPA B149.2 or CSA
B149.1 Natural Gas and Propane Installation Code, and
the National Electrical Code, ANSI/NFPA 70.
Correct LP Gas Tank Use
LP gas grill models are designed for use with a standard 20
lb. Liquid Propane Gas tank, not included with grill. Never
connect your gas grill to an LP gas tank that exceeds this
capacity.

If an external electrical source is utilized: The outdoor
cooking gas appliance, when installed, must be electrically
grounded in accordance with local codes or, in the absence
of local codes, with the National Electrical Code,
ANSI/NFPA 70, or the Canadian Electrical Code, CSA
C22.1.

CAUTION: Beware of Flashback

CAUTION: Spiders and small insects occasionally

spin webs or make nest 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 gri ll
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. A
clogged tube can be lead to a fire beneath the grill.

WARNING

Keep any electrical supply cord and the fuel supply hose
away from any heated surfaces.

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.

Visually check the burner flames prior to each use. The
flames should look like this picture. If they do not, refer to the
burner main tenancy part of this manual.

Safety Instruction continued

INSECT WARNING

Spiders and insects can nest in the burners of this and any
other grill, and cause the gas to flow improperly. This is a
very dangerous condition, which can cause a fire to occur
behind and beneath the valve panel, thereby damaging the
grill and making it unsafe to operate. Inspect the grill at least
twice a year.

WARNING

Keep a spray bottle of soapy water near the gas supply
valve and check the connections before each use.

DO NOT USE ALUMINUM FOIL TO LINE THE GRILL
RACKS OR GRILL BOTTOM.

This can severely upset combustion airflow or trap excessive
heat in the control area.

DO NOT LEAVE THE GRILL UNATTENDED WHILE
COOKING.

SAFETY PRACTICES TO AVOID PERSONAL INJURY

When properly cared for your grill will provide safe, reliable
service for many years. However, extreme care must be
used as the grill produces intense heat that can increase
accident potential. When using this appliance basic safety
practices must be followed, including the following:
Do not repair or replace any part of the grill unless
specifically recommended in this manual. All other service
should be referred to a qualified technician.
This grill is not intended to be installed in or on recreational
vehicles or boats.

Use a covered hand when opening the grill lid.
Never lean over an open grill.

When lighting a burner, pay close attention to what you are
doing. Make certain you are aware of which burner you are
lighting, so your body and clothing remain clear of open
flames.

When using the grill, do not touch the grill rack, burner
grate or immediate surroundings as these areas become
extremely hot and could cause burns. Use only dry
potholders. Moist or damp potholders on hot surfaces may
cause steam burns. Do not use a towel or bulky cloth in
place or potholders. Do not allow potholders to touch hot
portions of the grill rack.

Grease is flammable. Let hot grease cool before attempting
to handle it. Do not allow grease deposits to collect in the
grease tray at the bottom of the grill’s firebox. Clean the
grease tray often

Do not use aluminum foil to line the grill racks or grill
bottom. This can severely upset combustion air flow or trap
excessive heat in the control area.
For proper lighting and performance of the burners keep
the burner ports clean. It is necessary to clean them
periodically for optimum performance. The burners will only
operate in one position and must be mounted correctly for
safe operation.

Clean the grill with caution. To avoid steam burns, do not
use a wet sponge or cloth to clean the grill while it is hot.
Some cleaners produce toxic fumes or can ignite if applied
to a hot surface.

Children should not be left alone or unattended in an area
where the grill is being used. Do not allow them to sit, stand
or play in or around the grill at any time.
Do not store items of interest to children around or below the
grill.
Do not permit clothing, pot holders or other flammable
materials to come in contact with or too close to any grate,
burner or hot surface until it has cooled. The fabric could
ignite and cause personal injury.

For personal safety, wear proper apparel. Loose fitting
garments or sleeves should never be worn while using this
appliance. Some synthetic fabrics are highly flammable and
should not be worn while cooking.

Only certain types of glass, heat-proof glass ceramic,
earthenware, or other glazed utensils are suitable for grill use.
These materials may break with sudden temperature
changes. Use only on low or medium heat settings in
accordance with the manufacturer’s guidelines.

Do not heat unopened food containers. A build-up of
pressure may cause the containers to burst.

Turn off grill controls and make certain the grill is cool
before using any type of aerosol cleaner on or around the
grill. The chemical that produces the spraying action could,
in the presence of heat, ignite or cause metal parts to
corrode.

Do not use the grill to cook excessively fatty meats or other
products which promote flare – ups.
Do not operate the grill under unprotected combustible
constructions. Use only in well ventilated areas. Do not use
in buildings, garages, sheds, breezeways or other such
enclosed areas.

Keep the area surrounding the grill free from combustible
materials including, fluids, trash, and vapors such as
gasoline or charcoal lighter fluid. Do not obstruct the flow of
combustion and ventilation air.

WARNING
This outdoor cooking gas appliance is not intended
to be installed in or on boats. And other recreational
vehicles.
