Black buttons in water heater compartment

I have the Suburban sw6de water heater. first year i bought the trailer i had the rv place do the winterizing. new to travel trailers, went to pick it up in the spring and headed out. fired up the water heater and blew up the element and the gas quit. they never explained that they left the anode rod out and bypass had to be switched. put in a new element and it worked but the gas side would not.
i see the the 2 black buttons on the front. i assume that the reset went on the gas side. the instructions are******so do i have to remove the rubber part and then reset or just push the rubber in. I tried pushing the rubber in but didnt work. and what side is the gas reset?

The two black buttons as mentioned are resets for high temp limit t-stats

They are two sets of t-stats under the covers
One set is for electric element...110V AC....Bottom t-stat is 'normal' pre-set at 130*F & Top t-stat is 'ECO' (high temp) t-stat pre-set at 170*F
The other set is for LP gas...12V DC.....same set up/same temps

If 'normal' fails to open then when temp reaches the ECO set point it opens and shuts down all power to the heating source.
Until it has been reset to workie.......


If you ever need to replace the t-stats..they come in a set and you need to get the correct voltage 110V AC OR 12V DC.....not interchangeable

The function and operation should be covered in the Operator's instructions.
If you don't have the instructions for your appliances, they are available for download from the manufacturer's websites.

I believe those are Hi limit switches for both the gas and electric heat.
