Gas PipingQuestion 245 of 360
Where should the sediment trap be installed in relation to the appliance shutoff valve and the appliance gas control?
a.Upstream of the shutoff valve, near the meter
b.Anywhere on the branch is fine
c.Only inside the appliance cabinet
d.Downstream of the shutoff valve and as close as practical to the appliance inlet, ahead of the gas control
Explanation
The sediment trap is placed downstream of the appliance shutoff valve and just ahead of the appliance gas control, as close as practical to the appliance inlet. In that position it can catch debris before the gas reaches the control valve. It is typically a tee with a short capped nipple pointing down.
