CONNECTION Liquid Propane Gas Grills

Type of Gas

Your LP grill is factory built to operate using liquid propane only. Never attempt to operate your grill on gases other than the type specified on the grill rating plate.

The regulator supplied with your liquid propane gas grill is set for 11” water column pressure and is for use with propane gas only. This regulator and the factory-supplied hose assembly must be used when operating your grill with a 20 lb. LP gas cylinder.

If replacement of the hose and/or regulator becomes necessary, factory-specified parts are required.

For safety and design reasons, the conversion of a Ducane® grill from operation using LP gas to operation using natural gas requires the change out of the entire gas supply system of the grill. If this becomes necessary, see your dealer for additional information.

Handling Liquid Propane Gas

Propane gas should be handled and stored with care. We suggest asking your propane gas dealer, when having your tank filled, for a short course in handling, care and storage of propane gas tanks. Most dealers will be glad to instruct you on how to store and handle your tank. Make sure your tank is never stored inside! Keep it outside in a well-ventilated area in an upright position away from your gas grill.

Portable Installation

Complete portability is afforded to the grill head when mounted on the portable cart. When so installed, it is necessary to use a 20 lb. capacity liquid propane tank. Use no other size. The tank retainer is designed to accommodate only this size tank.

Type of Liquid Propane Tank

For LP gas grills, the LP gas supply cylinder to be used must be constructed and marked in accordance with the specifications for LP Gas Cylinders of the US Department of Transportation (DOT) or the National Standard of Canada, CAN/ CSA-B339 Cylinders, Spheres and Tubes for the Transportation of Dangerous Goods. This tank must be provided with a shut-off valve terminating in a liquid propane gas tank valve outlet. The valve must be equipped with a Type 1 connection complying with the latest edition of ANSI Z21.58.

Installing Liquid Propane Tank

The Propane tank is installed through the back of the base cabinet. Lift the liquid propane tank into the cabinet and rest it in the base opening. Position the valve opening facing out to the rear of the grill.

Ducane recommends the use of cylinder manufacturer’s Manchester and Worthington, with a 47.6 lb water capacity. Other cylinders may be acceptable for use with the appliance provided they are compatible with the appliance retention means (see illustration).

IMPORTANT

The liquid propane tank supply system must:

1.Have a safety relief device having direct communication with the vapor space of the tank.

2.Be arranged for vapor withdrawal.

3.Include a collar on the tank to protect the tank valve.

4.Be equipped with an overfi ll protection device (OPD). The tank should be 12 inches in diameter and 18½ inches tall.

CHECKING GAS LEAKS

Before operating your grill and after refueling, check carefully to be certain that all connections are tight and there are no gas leaks. The easiest way to do this is to mix up a little soapy water, like you would for washing dishes. Turn on the gas and brush a little of the mixture around fi ttings. If new bubbles form, you have a leak!

IMPORTANT

 

 

 

 

If there are local codes that apply to portable gas grills, you will have to conform to

 

 

 

 

them. Installation must conform with local codes or, in the absence of local codes, with

 

 

 

 

either the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Natural Gas and Propane

 

 

 

 

Installation Code, CSA B149.1, or Propane Storage and Handling Code, B149.2.

 

 

 

 

• Check that the area under the control panel and the bottom tray are free from debris

 

 

 

 

that might obstruct the fl ow of combustion or ventilation air.

 

 

 

 

• The areas around the LP cylinder must be free and clear from debris.

 

 

 

 

Type 1 Connective Coupling

 

 

 

 

All Ducane liquid propane gas grill regulators are equipped with a UL-listed tank

 

 

￿

￿

connection as per the latest edition of ANSI Z21.58. This will require a liquid propane

 

 

tank that is similarly equipped with a Type 1 connection in the tank valve. This Type 1

￿

￿

coupling allows you to make a fast and totally safe hookup between your gas grill and

your liquid propane tank. It eliminates the chance of leaks due to a POL fitting that is

not properly tightened. Gas will not flow from the tank unless the Type 1 coupling is

fully engaged into the coupling.

WARNING: The Type 1 connective coupling supplied with

your grill must not be replaced with a different type of grill/tank

 

 

connection system. Removal will result in loss of warranty and,

 

 

if improperly done, may result in serious bodily injury or death,
