4.6 Connections
4.6.1 Movable Appliance Connections
Terminations with appliance connectors:
Movable appliances such as gas ranges and dryers must be
connected to the CSST system using an approved appliance
connector. Connection to the Parflex system can be made
at a flange fitting terminated outside the wall eliminating
concealed fittings. The straight or elbow appliance stub-out
mounted to the stud face can be used to provide an uncon-
strained tubing connection away from penetration threats.
An appliance stubout (Parker Part No. ASO1/2) can also be
used to provide a rigidly mounted stubout for all movable ap-
pliances. This stubout gives only a 1 inch projection past the
wall board in areas where space is limited.
Section 4.0 Installation Practices
4.6.2 Non-Movable Appliance Connections
Direct Connections — The Parflex system may be directly
connected to non-movable appliances such as furnaces,
boilers, water heaters and permanently mounted ranges
or cook-tops. This direct connection eliminates the need
for a termination or appliance connector. The term direct
connections is not to eliminate the need for drip legs or
shut-off valves where required by code.
4.6.3 Specific Applications
Barbecue Grills
• Connections to movable grills must be made by
terminating the Parflex System (see section 4.6.1
Movable Appliance Connections) and using an outdoor
appliance connector.
• The Parflex system provides a quick disconnect device
(part number GASOUTLET shown below which can be
used for connection to barbecue grills).
