It is safe to have the exhaust of the generator blowing under a deck?

If I have it installed like that the front of the generator will be facing the house, it can be reversed but then the back of the generator and exposed pipes will be facing the house (generator has to be placed 3 feet away from the house so that it is 5 feet from the windows...generator is lower than the bottom of the window due to sloping of the lot).

Which would be best? I read that the back of the generator is twice as loud as the front. Install is taking place tomorrow so any info would be greatly appreciated!

My old 14KW was installed so that exhaust was blowing under the deck steps. Deck is 2 stories tall though. It exhausted along the back of the house and between the pool, right to my bedroom window! I believe the loudest side of the generator is the exhaust side. So when I had my 22KW installed I turned it so the intake was facing the house and exhaust was going out into the open yard to cut down on the noise. My opinion, depending on what space you have, I’d have the exhaust away from the house. I can hardly hear mine run inside the house now, much more quite than the last position.

There are fire regulations that would prohibit a lot of under-deck installations. I get the impression that the location may not have been reviewed by someone who understands all of the applicable codes.

Before you have folks install the generator, it would be good to have folks who know what they are doing review all codes for the installation - physical location, fuel related, and electrical.

Replacing an older LC unit placed under some stairs leading to a deck. Owner initially wanted it under the deck and other dealers were supposedly going to put it there.
The height was questionable since you need 60" from the top of the enclosure to any framing.
The owners conceded and so it's now going just outside of the deck.

I won't install one under a deck in the odd chance of fire. Not worth it to me, hire someone else!

You can't regardless of height if it's enclosed.

I will do most anything to get the noisy end pointed away from people, and the heat and smell that goes along with it.

Are we still talking about generators?

I guess it all depends on who it is that gets the noisy, smelly end pointed at them!

This is an example of what Not to do.
Fyi, there were 2 gas can on bottom shelf by the exhaust vents. Nice....
This was many years ago, done by a "big box " store installer.
I was there to replace the starter under warranty, per Generac, it was moved from this location out into yard after the inspections department was contacted.

Sorry can't resist another one of my favorites.
Homeowner: it keeps shutting down for no reason, I re-set it, and then a few hours later it just shuts down again. :confused:

redman those are are two good examples of what not to do. Never mind rules and regs, a complete lack of common sense !



Obituary of Common Sense !


Today, we mourn the passing of an old friend by the name of Common Sense.

Common Sense lived a long life, but died from heart failure at the brink of the Millennium. No one really knows how old he was since his birth records were long ago lost in bureaucratic red tape. He selflessly devoted his life to service in schools; hospitals, homes, factories and offices, helping folks get jobs done without fanfare and foolishness.

For decades, petty rules, silly laws and frivolous lawsuits held no power over Common Sense. He was credited with cultivating such valued lessons as to know when to come in from rain, the early bird gets the worm and life isn't always fair.

Common Sense lived by simple, sound financial policies (don't spend more than you earn), reliable parenting strategies (the adults are in charge, not the kids), and it's okay to come in second.

A veteran of the Industrial Revolution, the Great Depression, and the Technological Revolution, Common Sense survived cultural and educational trends including feminism, body piercing, whole language and new math.

But his health declined when he became infected with the "if-it-only-helps-one-person-it's-worth-it" virus. In recent decades, his waning strength proved no match for the ravages of overbearing federal legislation.

He watched in pain as good people became ruled by self-seeking lawyers and enlightened auditors. His health rapidly deteriorated when schools endlessly implemented zero tolerance policies; when reports were heard of six year old boys charged with sexual harassment for kissing a classmate; when a teen was suspended for taking a swig of mouthwash after lunch; when a teacher was fired for reprimanding an unruly student. It declined even further when schools had to get parental consent to administer aspirin to a student but couldn't inform the parent when a female student is pregnant or wants an abortion.

Finally, Common Sense lost his will to live as the Ten Commandments became contraband, churches became businesses, criminals received better treatment than victims, and federal judges stuck their noses in everything from Boy Scouts to professional sports.

As the end neared, Common Sense drifted in and out of logic but was kept informed of developments, regarding questionable regulations for asbestos, low-flow toilets, smart guns, the nurturing of Prohibition Laws and mandatory air bags.

Finally, when told that the homeowners association restricted exterior furniture only to that which enhanced property values, he breathed his last.

Common Sense was preceded in death by his parents Truth and Trust; his wife, Discretion; his daughter, Responsibility; and his son Reason. His three stepbrothers survive him: Rights, Tolerance and Whiner.

Not many attended his funeral because so few realized he was gone.

It's amazing to me the things we all see that don't end up burning down a house or killing someone.
Only thing we can do is bring it to the owners attention and report it to the inspection dept. If it's a warranty related issue as you mentioned the install needs to be fixed before the warranty repair can be.

They end up paying one way or the other if they go on the cheap with the install. Hopefully it's not the ultimate price.....

thanks for the responses guys! I am using a qualified installer, but I did not like his proposed positioning for aesthetic reasons. The generator was not going to be under a deck, I wanted it to be placed 36 inches away from a 4 foot high deck such that the exhaust would be blowing under the deck. The installer told me that it was not against any codes but that he wouldn't do that at his own house. Anyways...we figured out another solution and I should be all hooked up soon!
