Need help with Temp adjustment on a BW


Hello and thanks for reading.
My water heater is a 50 gallon Bradford White Model # MITW50L6BN12
The temperature is set a little to high for my liking so I read the manual and removed the thermostat cover per the instructions.
My question is this.
Where is the temperature adjust screw?

The picture in the manual looks nothing like the thermostat. It shows a screw in the center bottom with the words very hot and hot labeled underneath the screw. I don't see this on my thermostat. What I see instead is a plastic Honeywell module bolted to the metal gas valve. This module has an on/off switch on it. There are several screws on the metal gas valve one of which looks like the temperature adjust (half inch wide with a straight slot for turning) screw but there is nothing near it printed that would suggest it controls temperature. The manual says to turn it clockwise to get the temperature down. This isn't a set it and test it right away kind of thing so I was hoping for a pointer in the right direction. I can snap a few photos if that would help.

Here they are. I'm guessing its the big screw in the "top" picture. If so, does twisting it clockwise mean I will lower my water temp? Thanks.

So you are suggesting removing the screws and pull that Honeywell module (tan cover) off? Do I need to turn the whole thing off to do this? This seems way more complicated then it should be

The screws that you are referencing is the gas controller and you don't want to mess with those.

There is a plate to the right of the gas control that will have the temperature control behind that. At least that is where I have seen them. Pull it off and take a look.

To change the temperature there is no reason to turn off the gas.

I can see why you would think that....until someone with little fingers and not a care in the world either turns the heat all the way up or all the way down....then you'll be thankful that it's covered and controlled.

It looks like the tan cove has wires going into it, right? From the picture it shows a couple of RESET buttons, most likely they will be near where the wires go, so yeah...check under the tan cover...a couple of screws and you're in.

You are going to have a hard time getting that cover of. After looking closely at the top picture, it looks like it has tamper resistant TORX screws. Temp control should not be that difficult to get at. Must be somewhere else.
That bottom picture is an electric thermostat. Is there any reference to a gas control in the manual?

All the gas units I have seen have large red knob on the gas control for temperature adjustment. You can't miss it. It is 2" diameter.

Thank you Marvin, and everyone else who weighed in.
The manual said take off the cover on the right side of the gas valve. Well there was a cover on the gas valve, and that's what I removed (only two screws). Depending on how you look at it, it could have been the right side of the gas valve. There is also a cover on the water heater itself, also on the right of the gas valve. This cover blended in very well to the tank, so I didn't even notice the single screw holding it on. Once I removed this cover, then the picture in the manual matched the thermostat. Good thing I didn't take apart the gas valve. Kaboom!!!
Here is the picture after I adjusted it. In this case I needed to turn the dial counterclockwise to lower the temperature.

Hopefully I won't get socked in the noggin by my wife after she takes a cold shower tomorrow morning.
