Yes, the heater should operate correctly at 7500ft. Above 7700 feet the burner will require modification from the installer.
Hook a garden hose to the hose bib on the bottom side of the tank and place the other end outside or into a drain. Turn the thermostat to the off position. Turn the water off to the unit. Open a hot water faucet as far away from the unit as possible and leave it open. Open the release valve on the upper side and then open the hose bib valve to the right of the thermostat. It will take a while so be patient. Make sure your hose is flowing downhill or buy a small pump that connects to your drill and pump it out if you don't want to wait. There about $10 at Home Depot. After it's empty, I turn the water back on for a few minutes to flush out any loose left overs. Then shut the water off again and reverse what I did in the beginning except don't light the water heater yet and, I leave the hot water faucet open AND I open the cold water faucet at the same time. This lets the trapped air bubbles escape and prevents the pipes from knocking when the water is turned on and off. After you don't hear any more air escaping, close the hot and cold faucet and let the water heater fill up. You can light the water heater again anytime after you close the faucets. After the water stops running into it, open the hot and cold faucets for about 30 seconds then close again. Give it an hour or so and your water should be hot and running clear from the faucet. If it's not clear, you'll need to get a special cleaner to loosen the scale and redo the process.
The drain valve on this unit can and should be used as needed. It is tamper-proof to prevent small children from using it.
Yes. This is the procedure. Beats having little mitts draining the tank when turning a knob during the course of their day's fun and learning. Beats flooding the house as most people do not connect the drain valve to a drain as a matter of course.
This unit does not meet Energy Star guidelines.
The 100 is the series number. A.O. Smith makes minor changes in design every several years, and current natural gas models are Series 300.
The GCV units have a six-year warranty. XCV models have a ten-year warranty. The model number should be listed either on the water heater itself, or on the original invoice (if you still have it).

Yes, normally it is the day of install.
The warranty on the AO Smith 50 Gallon ProMax 6 Yr Warranty Residential Gas Water Heater - Tall Model starts on the date the unit is installed by a licensed plumber or the date of sale if not installed by a licensed plumber.
If you have an expansion tank on the system, the tank may need to be replaced. Another possibility is that the relief valve has a bad seal and needs to be replaced.
It sounds to us as if you may have calcium built-up on the bottom of the tank that is not allowing the burner to heat the water as rapidly as it used too.
