GAS INSTRUCTIONS
CHECK FOR GAS LEAKS
ƽ WARNING: The gas connections of your Summit
®
gas grill
have been factory tested. We do however recommend that
you leak check all gas connections before operating your
Summit
®
gas grill.
REMOVE CONTROL PANEL
Tool required: Phillips Screwdriver.
1) Remove the burner control knobs.
2) Remove the two screws that secure the control panel to the frame.
TYPE OF GAS
Your natural gas grill is factory built to operate using natural gas only. Never attempt to
operate your grill on gases other than the type specified on the grill rating plates.
Your grill operates at 4.5” of water column pressure. If replacement of the hose becomes
necessary, factory specified parts are required. See your local dealer.
For safety and design reasons, the conversion of a Weber
®
grill from operation using
Natural gas to operation using LP gas requires the change out of the entire gas supply
system of the grill. If this becomes necessary, see your dealer for additional information.
WHAT IS NATURAL GAS?
Natural gas, often called methane, is a safe modern fuel. Natural gas is supplied by your
local utility and should be readily available if your house is already heated with gas.
LEAK CHECK PREPARATION
CHECK THAT ALL BURNER VALVES ARE OFF
Valves are shipped in the “OFF” position, but you should check to be sure that they are
turned off. Check by pushing in and turning clockwise. If they do not turn, they are off.
Proceed to the next step. If they do turn continue turning them clockwise until they stop,
then they are off. Proceed to the next step.
