Question about Water Water Heaters
did you check the filters on the the water valves, i am not exactly sure about your codes that are shoeing but if you could read it and post them, i know on some of the units 76 means there is low water pressure and the filters are behind 2 caps one on each side above the shut off valve take off the caps and remove the screens, clean them and replace them ,, make sure you turn off the water on both side first or you will get wet

SOURCE: takes too long for hot water.
You need a recirculating line. You will have to hire a plumber to run a water line from the farthest fixture or to the fixture you are concerned about on the hot side and return it back to the water heater. this will cause hot water to constantly run throught the hot water line (via the recirculating line) and when you want to draw water from the fixture, you will already have hot water right at the line.
I know this works with standard tank water heaters, but it is a lil trickier with rinnai units(but very possible) if your plumber pleads the 5th and tries to sell you another unit call the Rinnai manufacturerand ask them how.

I just had the same problem and I fixed it in about an hour or 2.
First shut off the gas,water and power(unplug it)
Take off the cover
There are about 20 screws above the electrical circuit board.
You have to remove all of those screws to remove plate that is covering the burner assembly.
The burner assembly has these 3 pins that look like number 7's
these are covered with build up and gas can't flow right.
That's why you get the c211 error not enough gas.
Take a wire brush and gently remove any build up,
I also cleaned the thermocoupler which is next to the burners.
It looks like a metal pin with a couple of wires coming out of it this was also very dirty.
I took a can of air and basically freshened it up
It works perfect now.

All that you need is a long phillips screw drive and a drill because its about 25 screws
The burner assembly has 2 screws all the in back underneath the assembly once you remove those 2 the assembly comes out . You don't have to disconnect any wires.

If you look on the left hand side of the burner control module you'll see 4 capacitors - the capacitors have most likely failed...pretty sure anything code 76 is P/S failure. It may also be covered for manufactures defects. If the cap is blown..the top will be slightly raised as apposed to flat like the other nearby caps - they are called top blow capacitors...the damage should be evident.
