My OG (natural) gas water heater was installed without a sediment trap/drip leg so when I put in a new one I didn’t want/think to change configuration…in fact didn’t even realize these were a good idea, and probably code now. So I am planning to put on one.
From reading up and watching Youtube it seems pretty straightforward: shut off gas, disconnect gas line at either appliance inlet or just after shut-off valve (?!), install trap with plumbers/PTFE tape (or should I use appropriate pipe thread compound instead?), turn on gas and test for leaks (spray with some soapy water), then re-start water heater and monitor.
Planning to use this part from Lowes Depot:

Are there any tips or pitfalls I should know or have in mind? Is this galvanized thing they way to go? I note that the trap on my furnace feeds in horizontally, but the way the guy did it online it fed in vertically from top. Do I care? I ask only because the yellow gas feed line for the water heater has pretty much zero slack.
