Answer: 
For those of you who are not engineers, if this unit burns 312,000btu's/hr, at the current price of $2.10 per MMBtu (million British thermal units) the cost would be about $0.70 per hour at full load.

The answer actually depends upon the type of fuel you are using, the load on your generator and even what you are looking for in a value.
The Automatic Transfer Switch with this particular unit is a Service Entrance ATS Rated for a Whole House. With this in mind, I will assume a Full Load and therefor provide the fuel consumption rate at Full Load.
On Natural Gas the Full Load fuel consumption would be 261 Cubic Feet Per Hour. Your Natural Gas must provide at least 1000 BTU per Cubic Foot, so at Full Load you would consume 261,000 BTU Per Hour. (so your answer here is in BOTH Cubic Feet Per Hour AND in BTU Per Hour AT FULL LOAD.)
On Liquid Propane the Full Load fuel consumption would be 2-1/2 Gallons Per Hour. (2.51 but you may not be able to see the decimal point) This would be 91 Cubic Feet Per Hour. Your Liquid Propane must provide at least 2,520 BTU per Cubic Foot, so at Full Load you would consume 229,320 BTU Per Hour. (so your answer here is in; Gallons Per Hour, Cubic Feet Per Hour AND in BTU Per Hour AT FULL LOAD.)
Now, when your generator starts and runs an exercise cycle - it does not switch your home over to generator power - so it starts and runs at a Low Idle. It consumes very little fuel of either type. And the exercise cycle provides an audible confirmation that your generator is ready & able to start & run. This while self lubricating, so it has the ability to provide two services in the exercise cycle.
The homes I have been involved with - although they may have a 200 Amp service entrance - they don't consume 200 Amps. With no one home I've witnessed 10 Amp & less power consumption. Right down to 4 Amps. So, your load doesn't have to be Full Load every time your generator starts, it will vary with who is home and what they need to power.
These are the basics you should know & understand about fuel consumption.
If you live in very hot or very cold climates, or at a high elevation - you should talk to your fuel supplier about the effects which can take it outside of "basic".
I hope this helps.

Answer: 
How much gas depends greatly on the load your house presents. Generac's specifications say it uses 312 cuft/hr at full load, 193 at half load. Unless you run a couple of air conditioners and a clothes drier or cooking range, you'll very likely be well under full load. So a reasonable answer is, well under 300 cuft/hr.

Don't worry about the weekly exercise cycle as the generator does not transfer power - it merely starts and runs at a low idle to self lubricate. (It also provides an audible proof that it is in proper working order.) It consumes very little during this exercise.
Hope this helps.

When the generator is at a high load it uses a large amount of propane gas. The propane tank has liquid and gas forms of propane in it. As the propane gas is used the pressure in the tank drop and causes the liquid propane to boil and turn to gas. This actually cools the tank. On cold days a small tank may not be able to absorb enough heat from the air to boil the propane in the tank to create enough gaseous propane for the generator to run properly or it could other components in the propane fuel line to freeze as liquid propane is being converted to gaseous propane.

I took the liberty of scrolling back up to the "Product Overview". To the right of that is a box labeled "Info & Guides". I clicked on the one entitled "Full Product Manual" to look up what the Main Breaker is on the generators output. This would be the breaker mounted behind the door on the right end of the cabinet - as you look at the generator from the front.
Yes, I could have done the math but what I was looking for was the breaker. The last Generac 16 KW I installed had a 65 Amp breaker on its "output". This breaker protects the wiring that goes from the generator to the transfer switch. The 16 KW I installed had a 6' whip on it that was to be attached to the house AND inside that whip was #6 THHN STRANDED Copper power conductors.
If you ever look, down the side of a wire should be written information about the construction of that wire. The size of the wire, whether it is stranded or solid, copper or aluminum and even what its outer insulation or sheath(s) are built to protect the wire from. If you can't make out what it says, it's repeated over and over its entire length. Just insure that the power is OFF to the wiring you are trying to read.
I matched the wiring provided by the manufacturer. Generac used #6 THHN STRANDED COPPER. (If they would have run #4 THHN StrandedCopper then I would have run the larger wire myself just to avoid warranty issues.) I prefer to run a full sized Neutral so I didn't even try to read what they had - I used a #6 THHN Stranded Copper. I ran a #8 THHN Stranded Copper Ground to comply with Table 250-122 of the National Electric Code. Minimum Size Equipment Grounding Conductors for Equipment.
Forty Feet is not a problem.
There should be 5 to 6 control wires in that whip. They are used in conjunction with the Transfer Switch. They are normally #18 Stranded. Although small in size they carry 240 VAC between N1 & N2 alone. 120 VAC on T1. 12 VDC and the Transfer signal on the remaining control wires. So although small in physical size, they are potentially hazardous. Follow the instructions of your Installation Manual for these particular wires as I have seen both 5 & 6 wires required.
Again, Forty Feet should not be a problem.
I don't have a great demand for #18 THHN Stranded so I do substitute the larger #14 THHN Stranded Copper in its place.
Stay safe by keeping "EVERYTHING" OFF until you have completed your task. Locked out if there's any chance that it may get energized accidentally.
Hope this helps.

Answer: 
16 kW is a full-load current of about 65 amps at 240 volts, Coyotetodd, so the wire needs to be sized for that. The National Electric Code says THWN 6 AWG is rated at 65 A, THHN 6 AWG at 70. Home Depot carries THHN.

Rated 4.9 out of 5 by 100 reviewers.
Rated 5.0 out of 5.0 by One of our best purchases ever. In the last five months we have lost power six times. My wife and I talked about getting a generator but thought they would be way to expensive. Boy were we wrong! When I told my wife the price she said "order it" Four days later it was here and two days after it was installed. We have the 16,000 watt Generac with the whole house transfer switch. IT RUNS EVERYTHING. Very Very pleased. January 20, 2016
Rated 5.0 out of 5.0 by Good Value Excellent value to power my entire house. only negative was having to buy an additional smart control module to give the unit a better brain in deciding if certain circuits should be shut down during operation. very happy with the initial results. July 19, 2016
Rated 5.0 out of 5.0 by Great Purchase!!! Great product! Delivery company was excellent to work with. The Generac company and Home Depot are a great team!!! June 17, 2016
Rated 5.0 out of 5.0 by 16kw installed since 2009 My 16kw Generac Whole Home Standby Generator has been installed since July of 2009. A few years ago we were hit by hurricane Sandy! My generator ran for over 3 days straight providing power to everything from our alarm system to central air conditioning! It has been starting every Saturday since it was installed for the weekly test as well as through many power outages! Between weekly exercising and power outages if you added it up, would amount to over 350 starts! The best part, it has never failed to start or run, not even once! What does that tell you about Generc quality? I highly recommend that you follow Generac's guide to maintenance. It has proven itself to my family and I over and over again! June 14, 2016
Rated 5.0 out of 5.0 by Best thing I ever don't ! I have a 16 kw for about a year now I use it a number of times, it comes on in about 4 seconds and stays on too the electricity comes back on, the longest it's been on was about 4 hours. With hurricane season here and I live in New Orleans I'm glad I have it. July 6, 2016
Rated 5.0 out of 5.0 by Best money spent on our home We thought about a generator for years. Over time, we noticed we would lose power more often, anytime a stiff wind blew through the county. Saw an ad for generators, offering good financial terms, and decided to get one. The day before the installation, we lost power, confirming our decision to get a generator was correct. The generator starts weekly as scheduled; we have lost power several times, for a few minutes or most of a day - generator works like a champ. Best money we have spent on our home in nine years. June 23, 2016
Rated 5.0 out of 5.0 by Great product, has everything we need. Cannot say enough about the quality and workmanship of this generator. Everything from the initial call to the actual installation was fantastic. Mark walked us through everything step by step and made the whole process enjoyable. They did an excellent job installing the unit and left our home in terrific shape. GREAT JOB!! June 11, 2016
