Why is this wrong?

[Rich Sumen]

I just know this is not right but.......

Is this wrong because...
a. The flex connector is being used as a "supply pipe"?
b. The flex connector is ahead of the shut off and dirt leg"
c. Both
d. Or, It's ok.

Thanks for you comments

The location of the sediment trap is OK, however the shut off valve needs to be before the flex.

[Eric Barker]

"C" is the best answer of the option given. Technically, one end of the appliance connector should connect to an appliance, not a rigid pipe.

[James Duffin]

According to this manufactures installation instructions your setup looks OK.

What is shown in the photo is not CSST, it is flexible gas connector pipe.
Gas Connector goes between the appliance and the shutoff.

E. None of the above (A and first half of B and other).

It is wrong because
the gas appliance connector is being used as gas supply system piping. The threaded vertical drop (hopefully not "teed") gas pipe is too long/low. Shorter section, install valve there, sediment trap/dirt leg/drip-condensation leg and hard pipe lateral to appliance gas valve.

It is wrong because a gas appliance connector belongs on the appliance side of a gas shut off valve.

It is wrong to install a gas appliance connector to this installation because this is not a movable appliance it is a fixed appliance,
and upon a "platform" (!?!, whole other topic what else is wrong and/or questionable!),
apparently unsecured other than by its own weight,

The "intermediate" being improperly used as "supply" system piping is unsecured, unsupported, open to the area subject to damage, should not employ a pre-manufactured gas appliance connector. The paper tag on the gas appliance connector is restrictive of air flow to the appliance and encroaches on required clearance.

I agree, mostly, with Mr. Cantrell, but I disagree regarding the propriety of the supposed sediment trap in its present configuration, or location in relationship to the burner (plate) - serviceability of both the appliance - burner, etc. and the sediment trap itself - improper location incroaches on required clearances of both.

Shut off valves/stop valves tend to work better when they're installed in the correct orientation as to gas flow.

Mr. Duffin constantly mistakes a componant of a pre-manufactured gas appliance connector to be that of a gas supply system (CSST), it is not.
His pdf does not apply, nor even if we pretended that this was not a pre-manufactured gas appliance connector - it STILL doesn't meet the examples given in the pdf.

The black pipe drop is not a CSST manifold. The pictured "flexible connector" is not CSST gas tubing, which is a gas supply SYSTEM - neither is present in the OP photograph.
