WARNING
WARNING
LP GAS CYLINDER (NOT SUPPLIED WITH THIS GRILL)
The LP cylinder is available for purchase at the same location the grill was purchased.
The LP (Liquid Propane) gas cylinder specifically designed to be used with this grill must have
a 20 lb. (9.1 kg) capacity incorporating a Type 1 cylinder valve and an over-filling protection
device (OPD).
• DO NOT connect this grill to an existing #510 POL cylinder valve with Left Hand threads. The
Type 1 valve can be identified with the large external threads on the valve outlet.
• DO NOT connect to a propane cylinder exceeding this capacity.
• DO NOT connect to a cylinder that uses any other type of valve connection device.
INSTALLATION INFORMATION:
The installation of this appliance must be in accordance with:
All applicable local codes, or in the absence of local codes, either:
• National Fuel Gas Code ANSI Z223.1 NFPA 54
• Natural Gas and Propane Installation Code: CAN/CGA B149.1
• Natural Gas Installation Code: CAN/CGA B149.1 (Canada)
• Propane Installation Code: CAN/CGA B149.2 (Canada)
To check your local codes, see your local LP gas dealer or natural gas company. This grill was not
intended to be connected to a natural gas supply line. If an external electrical source is utilized, it
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 22.1.
• FOR OUTDOOR USE ONLY. DO NOT operate indoors or in an enclosed area such as a garage,
shed or breezeway.
• Use your grill OUTDOORS in a well ventilated space away from dwellings or other buildings to
prevent dangers associated with gas accumulation and toxic vapors. We recommend your grill
be situated at least 10 feet (3.1 m) from buildings.
• Maintain a minimum clearance of 36 inches (91 cm) between all sides of grill and walls or other
combustible material. DO NOT use grill under overhead unprotected combustible construction.
• DO NOT use or install this grill in or on a recreational vehicle and/or boat.

5
The cylinder must also be equipped with:
• A shut-off valve terminating in a Type 1 gas cylinder valve outlet.
• A Type 1 valve that prevents gas flow until a positive seal is obtained.
• An arrangement for vapor withdrawal.
• A collar to protect the cylinder shut-off valve.
• A safety relief device having direct communication with the vapor space of the cylinder.
• A listed over-filling prevention device (OPD).
• Turn off the cylinder valve when your grill is not in use.
• Handle the tank with care.
• Always secure the cylinder in an upright position.
• Never connect an unregulated LP gas cylinder to your grill.
• DO NOT expose LP gas cylinders to excessive heat or ignition sources.
• DO NOT store a spare LP gas cylinder under or near your grill.
• Allow only qualified LP gas dealers to fill or repair your LP gas cylinder.
• DO NOT allow the cylinder to be filled beyond 80% capacity.
• Read and follow all warnings and instructions that are on the cylinder and that accompany
this product.
• Never store a spare LP gas cylinder under or near your grill. This could cause excess pressure
to be expelled through the vapor relief valve resulting in fire, explosion, or severe personal
injury including death.
NOTE: PROPANE GAS IS HEAVIER THAN AIR AND WILL COLLECT IN LOW AREAS.
PROPER VENTILATION IS EXTREMELY IMPORTANT.
• Keep the ventilation opening(s) of the LP gas cylinder enclosure free and clear from
obstructions and debris.
• DO NOT insert any foreign objects into the valve outlet. Damage to the back-check could
result. A damaged back-check can cause a leak, possibly resulting in explosion, fire, severe
bodily harm, or death.
WARNING
DANGER
CYLINDER SPECIFICATIONS:
When purchasing or exchanging a cylinder for your gas grill, it must be constructed and marked in
accordance with the specifications for LP gas cylinders of the U.S. Department of Transportation
(DOT) or the National Standard of Canada, CAN/CSA-B339 Cylinders, Spheres and Tubes for
Transportation of Dangerous Goods; and Commission, as applicable; and provided with a listed
over-filling prevention device (OPD), and provided with a cylinder connection device compatible with
the connection for outdoor cooking appliances.

FILLING THE LP GAS CYLINDER:
• Allow only qualified LP gas dealers to properly fill or repair your LP gas cylinder.
• New tanks should be purged prior to filling; inform LP gas dealer if you are using a new tank.
• DO NOT allow the cylinder to be filled beyond 80% capacity. Over-filled tanks can create a
dangerous condition. Over-filled tanks can build-up pressure and cause the relief valve to expel
propane gas vapors. The vapor is combustible and if it comes in contact with a spark source or
flame an explosion causing severe burns, bodily harm, or death could occur.
• Always use a protective cylinder cap when grill is not connected to cylinder.
• If you exchange a cylinder with a qualified exchange program, be sure the cylinder has
a Type 1 valve and an over-filling prevention device (OPD).
INSTALLING THE LP GAS CYLINDER ONTO THE GRILL:
1. Check that the cylinder valve is closed by turning the knob
clockwise.
2. Place the cylinder into the tank holder in the bottom
of cabinet.
3. Orient the cylinder such that the valve opening faces the
side burner, and so that the hose is not kinked or damaged.
4. Fully tighten the cylinder clamp underneath tank holder to
secure tank.
5. Attach or detach regulator to the LP gas cylinder only
when cylinder is at rest in tank holder.
HOSE AND REGULATOR:
Your grill is equipped with a Type 1 connection device with
the following features:
1. The system will not allow gas flow from the cylinder until
a positive connection to the valve has been made.
NOTE: The cylinder valve must be turned off before any
connection is made or removed.
2. A thermal device that will shut off the gas flow if the device is
subject to temperatures above 240°F to 300°F (115°C to
150°C). If this should happen, remove the entire regulator
assembly and dispose of properly. A replacement regulator
assembly can be purchased by contacting customer service
at 800-527-0717. The cause of the excessive heat should be
determined and corrected before using your grill again.
3. A regulator flow limiting device, when activated, restricts the
flow of gas to 10 cubic feet per hour. If the flow limiting
device is activated, perform Regulator Resetting Procedure.

WARNING
• Never use your grill without leak testing all gas connections and hoses. See the section on
"Leak Testing" in this manual for proper procedures.
The pressure regulator and hose assembly supplied with your gas grill must be used.
• DO NOT attempt to connect it to any other fuel supply source such as a natural gas line.
• DO NOT use any other pressure regulator/hose assembly other than the one supplied with your grill.
Replacement pressure regulator/hose assembly must be part No 155-4400-0, which can be obtained
by contacting customer service at 800-527-0717.
• DO NOT attempt to adjust or repair the regulator. The regulator is designed to operate at a
maximum output pressure of 11 inches of water column (2.74 kPa).
During assembly and/or replacement of the gas cylinder, keep the gas supply hose free of kinks
and/or damage.
Visually inspect the hose assembly prior to each use for evidence of damage, excess wear, or
deterioration. If found, replace the assembly before using your grill. Only the manufacturer's supplied
replacement should be used.
CONNECTING HOSE AND REGULATOR TO AN LP GAS CYLINDER
• Ensure the tank valve is CLOSED prior to connecting the LP gas cylinder to your grill. Turn the
valve knob clockwise to properly close the valve. Read and follow all instructions and warnings
on the supply hose safety tags. Read and follow all warnings in this manual concerning the safe
use of LP gas cylinders and the hose and regulator before connecting cylinder to grill. Read
and follow all warnings on the LP cylinder.
CONNECTING HOSE AND REGULATOR
1. Check that the cylinder valve is closed by turning the knob clockwise.
2. Check that the grill’s burner control knobs are in the "OFF" positions.
3. Remove the protective plastic cap from the cylinder valve and the connection device.
4. Hold regulator and insert the nipple of connection device into the LP cylinder valve outlet. Ensure that
the device is centered properly.
5. Turn the large coupling nut clockwise by hand and tighten to a full stop. Take care not to cross thread
the coupling nut onto the cylinder valve. Do not over-tighten the knob onto the valve. Do not use tools
to tighten connection.
NOTE: If you are unable to make the connection, repeat Steps 4 and 5.
6. Check that the hose does not contain kinks, does not contact sharp edges, and does not contact
surfaces that may become hot during use.
7. Leak check all fittings before lighting your grill. See section on "Leak Testing" in this manual.
WARNING
WARNING
