GAS PLUMBING REQUIREMENTS

A pressure regulator must be installed on all gas equipment. All local codes require that a pressure regulator be installed. Removing or failing to install the pressure regulator can result in fi re and serious bodily harm.
An installer supplied gas shut-off valve must be installed in an easily accessible location for all hardplumbed natural gas and liquid propane applications.
In order for a the grill to perform properly, you must have adequate gas plumbing. Please see the guidelines below to help ensure that you have the appropriate gas plumbing with respect to gas pipe diameter, length of pipe run and the grills BTU requirements.

Important note for 30”/42”/54” Grills:
The main burner and power burner on the 30”/42”/54” grills require a long orifice.
These orifices are 1.375” in length. Failure to use the longer orifice on these models could result in a serious fire.

Checking for Gas Leaks

WARNING

To prevent fi re or explosion hazard, DO NOT smoke or allow any potential source of ignition (sparks, electrical arcing, etc) in the area while performing a leak test. Leak tests should be conducted outdoors only. Never conduct a leak test using fi re or fl ame.

Create a soapy solution of 1 part soap and 3 parts water.

Confi rm that all control knobs are in the off position.
Turn on the fuel supply. For natural gas, turn the valve handle 1/4 turn to align with the gas fl ow.
For L.P., turn the cylinder valve knob counter clockwise one full rotation.
Apply the soap solution generously by paint brush or squirt bottle on all connections and fi ttings.
If bubbles appear to “grow” on any of the connections, you have a gas leak. IMMEDIATELY turn off the gas supply.

Fixing a Gas Leak:

Shut off the gas supply
Turn all grill controls to the “ON” position to purge the grill of any gas build-up, then turn the controls back “OFF”.
Wash off the soapy solution with cold water and dry.
Tighten the loose joint, or replace the faulty part with manufacturer-recommended replacement parts.
DO NOT attempt to repair the L.P. cylinder valve if it is damaged. The only way to safely resolve a damaged cylinder is to REPLACE IT.
Repeat the leak test to ensure that no leaks are present.

Lighting Your Grill
For the Main Burner, ProSear™ /Trident Burner or Accessory Burners:
Push and hold the control knob in for 5-7 seconds, allowing the igniter to heat up. Then rotate the knob to “LITE”. After ignition, set the knob to the desired heat setting.

ADJUSTING BURNER FLAME
Replace the burners. Light the grill to check fl ame height. Adjust low fl ame height with the 3/32” slot blade screw driver.
Turn the burner valve to the low position. Hold the valve stem in position by hand and insert the screwdriver into the hole in the valve stem. Turn the screwdriver right or clockwise to reduce fl ame and left or counterclockwise to increase fl ame height.
Open and close each valve twice to insure the fl ame height did not change. Re-install all parts and replace all panels removed

For the Rotisserie Burner:
The rotisserie burner features a thermocouple sensor with a safety valve that automatically shuts off the fl ow of gas if the burner goes out. To light the rotisserie burner, push and hold the control knob in for 2 seconds and then turn the knob to the “LITE” position. After ignition CONTINUE HOLDING THE CONTROL KNOB IN for 30 to 60 seconds. During this time the thermocouple will heat up and the safety valve will remain open. If you release the control knob before the thermocouple has heated up, the safety valve will shut off the fl ow of gas to the rotisserie burner and you will have to re-light the burner.
