Gas PipingQuestion 262 of 360
Which installation practice for a flexible appliance connector is correct?
a.Keep it accessible and in the open, not concealed in a wall or behind an immovable appliance
b.Cut it to length and re-flare the ends on site
c.Reuse the old connector from the previous appliance
d.Bury it in the slab for a clean look
Explanation
An appliance connector must stay accessible and out in the open for inspection and service, not concealed inside a wall or trapped behind an appliance that cannot be moved. Connectors are factory assemblies that are not cut or re-flared in the field, and a new connector should be used rather than reusing an old one. These rules reduce the chance of an undetected leak.
