Gas & FuelQuestion 70 of 110
Each gas appliance must have an accessible manual shutoff. Where must the appliance shutoff valve be located?
a.Inside the appliance cabinet
b.In the same room, within 6 ft of the appliance, upstream of the union and appliance connector
c.At the meter only
d.Anywhere in the building
Explanation
The appliance shutoff must be in the same room as the appliance and within 6 ft of it, located upstream of the flexible connector and union so the appliance can be isolated for service. Placing it only at the meter would require shutting off the whole building. Accessibility without tools is required for emergencies.
