Natural Gas sediment trap

[D Sveden]

Is a sediment trap required prior all natural gas appliances? I've used them just prior to my water heater connection and a wall mounted vent-free heater. I am specifically wondering about just prior to a shut off valve for a range. The gas pipe is running below the floor and makes a 90 up through the floor. Should there be a sediment trap below the joint as the pipe makes the 90 up to the kitchen?
Thanks

I've never seen one on an appliance before - doesn't mean you couldn't do it. I suppose it could add a few years onto the life of the burner.

In Canada, there are some things that do not require a sediment trap. Stoves, dryers and gas fireplaces.
In our code, if there is a trap. it must be accessible.

It varies with codes but a rule of thumb seems to be that any appliance that runs thermostatically has to have a trap. So stoves, some space heaters, some logs, etc. would not require one. It's usually a good idea to have a trap in the lowest point of the system with natural gas too I believe but I could be wrong. I don't do much with natural gas.
