Answer: 
The GE recommended specs for this 20kw model is 18 inches from the house. Most city codes follow the manufacturer's specs. I had to call GE and they emailed me the installation page with the placement photos. You may need to do this for a city inspector.

Answer: 
This unit only comes on when the power is out for more than...20 seconds I believe. I have my unit set for an "exercise" cycle every week - 10 minutes to keep it...healthy. This generator is a lifesaver - after Hurricane Sandy cut our power for a week, we invested quite a bit to have this system installed. It was been worth every penny...

Answer: 
You probably won't even notice it on your fuel bill if you have other items using the fuel. It'll just blend in.
When they run an exercise cycle they do so at NO LOAD, which is to say that they DON'T transfer your home to generator power. ( They only transfer when there is an actual power outage. )

Answer: 
It depends on your fuel source, Natural Gas or Propane? I have not had an outage longer than 20-30 minutes since installation so I can't say what it would cost to run continuously for a week or more. We use Natural Gas which is cheap.

GE 20kw generator - where does the exhaust exit the cabinet?

This question is from 20,000-Watt Air Cooled Home Generator System with Symphony II Whole House 200-Amp Automatic Transfer Switch
Asked by

It looks like there is an opening in the front of the cabinet, but I am not sure if the exhaust is directed through that opening. I assume that the noise is loudest wherever the exhaust exits the unit and that's why I am asking the question.

Answer: 
The air intake on this model is on the right side (with a front view) and the exhaust is in the front on the far left side. See the photos I uploaded in my review. The exhaust is emitted at approx. 500 degrees and GE recommends a 5 foot clearance from combustible plants and vegetation.

Customer Reviews

Rated 4.4 out of 5 by 56 reviewers.
Rated 5.0 out of 5.0 by Satisfied Customer Generator and Transfer Switch ships directly from Briggs and Stratton plant in Wisconsin. Product was delivered to house on time. Hired an electrician to install and a GE certified dealer to oversee installation and start up. Electrician had no trouble installing it and GE dealer (Houston) was great to deal with. Don't cheap out on the installation and be sure to sign up with a local dealer for the annual maintenance contract - it is well worth it. Generator performs a weekly self-diagnostic check and runs for 20 min. Very satisfied with this purchase. Wireless monitor works well too. Note: Air intake is on the right side and discharge is in the front on left side (see attached photos) November 14, 2013
Rated 2.0 out of 5.0 by Generator don't last long I had the 20kw home generator installed 5 years ago and kept in good maintenance condition. We had lost power quite few times over last 5 years and the generator always starts flawlessly. However this pass week during its weekly excersise cycle, the generator just stopped in the middle of the cycle. It turns out the cylinder wall got a hole browned thru. My generator has a total run hour of 145 hours. This is low usage over 5 years and now the generator is totally useless. Not a very good quality product November 12, 2015
Rated 1.0 out of 5.0 by Don't buy a GE Generator We have had nothing but problems for 2 years with our generator. In fact it has never worked each time we needed it in a power outage. Still trying to fix it. November 23, 2015
Rated 5.0 out of 5.0 by 20kw I decided the 20kW would meet my needs. I power the generator using natural gas, July 15, 2016
Rated 1.0 out of 5.0 by Does not have Fire Code Rating The generator casing is not rated for 1 hour fire as the other brand which means it must be located 5 feet from your home / building due to the Fire Hazard. The other brand is Fire Rated, has a sticker on it and has to be mounted 18 inches or more from the house (not 5 feet away). This is why some of the major retailers do not carry this product in their stores. The home owner with limited yard space should go with the other brand! Baltimore County, MD require permits and inspection on the electrical and gas installation, to code. Natural gas supply / meter has to be upgraded too. Generator is not returnable where the other brand is up to 30 days. October 30, 2014
Rated 5.0 out of 5.0 by Great investment My wife and I decided to invest into a generator after Hurricane Sandy left us with no power for a week. I shopped around and decided to get the GE model. I've had it now for almost 2 years and it has done everything I expected. We have lost power now @ 6 times the last year and our GE generator has kept us with all the power we required - A/C, water (we have a well) lighting - everything. We live in a rural area, and we are the last on the grid to get our power restored. It is no longer an issue, except our neighbors do not like us turning every outside light on during a power failure ;) A great product... November 26, 2014
Rated 3.0 out of 5.0 by Must be 5 Feet From House In Baltimore, MD the county requires it to be 5 feet away from house no matter what the manual says. The generator does not certain stickers / certifications that others have which can be closer to the house. GE Standby Generators 20KW are not the preferred generator manufactory by contractors. Where I put my generator is on a brick wall with No Windows! Also I understand that the generator has to be downgraded to a 18KW Setting with Dip Switches due to it running on Natural Gas. November 19, 2015
Rated 5.0 out of 5.0 by Neat appearance I called Mr Sparky and made an appointment. Mr Chad Blanton came out in a few days to discuss my gen needs. We came to a solution and he and Mr Dallas came back in few days for the installation. These two guys were very efficient and done a very professional job. They even replanted a flower that was in the way during installation. I was very pleased with their service and how neat and respectful they were when they replanted my flower. Mr Blanton came back after gas was installed and started the gen up. He was very helpful and explained things that I needed to know. These two guys were very curtious and professional August 7, 2015
