disconnect .
• An additional manual shut-off valve indoors should be installed in the branch fuel line
in an accessible location near the supply line .

quick disconnect fitting is a hand-operated device that automatically shuts off the flow
of gas from the source when the barbecue is disconnected .
• The quick disconnect fitting can be installed horizontally, or pointing downward.
Installing the fitting with the open end pointing upward can result in collecting water
and debris .

disconnect fitting clean while disconnected .

sulfide per 100 cubic feet of gas .
• Plastic tubing is suitable only for outdoor, underground use.

must be protected against corrosion in an approved manner .
