Usually, it needs to be like 6 feet from a window. I'm not sure if that house vent is considered a window. Is there a basement there?

Furnaces do not produce carbon monoxide when operating as designed they produce carbon dioxide.

If your furnace produces carbon monoxide it is most likely starved for combustion air.

CO = carbon monoxide CO2 = carbon dioxide

Starved for combustion air = not enough Oxygen. Notice the only difference between the 2 gases above? (1 atom of oxygen) .

You won't enjoy the smell if the exhaust drifts over to where you are. It isn't great for plants right in front of the vent, though maybe it's the heat that plants don't like. The 92% AFUE furnace we had installed in 1999 killed the boxwood in front of its vent. That furnace sent out 8% of its heat out through the vent. A more modern furnace sends out a lot less, like only 2% for a 98% AFUE model.

Where are you located? If you have any snow you are going to have problems.

Minnesota. We get quite a bit of snow. However, I do have a dryer vent that is only 12 inches off the ground too... and that one doesn't seem to have any problems since it always melts the snow.

The installers should have left you the furnace installation manual. Check out the venting requirements and options.

The picture you posted is a combination exhaust and air intake. Is the air intake connected to this exterior port or is it open at the furnace to pull in the basement air? If snow and ice block the outside air intake the furnace will shut down.

Yup as mike mentioned its a combo intake and exhaust. Nothing wrong with it in the back yard. You use that for functions in the winter? Doubt it. It isnt active during the summer.

If that is a combination intake/exhaust vent, my big concern in Minnesota would be what happens when it snows. It looks like the height would be well within the normal snowfall range in Minnesota, which would block combustion air and exhaust.

is it bad for dogs to walk under whole its on? my dog just did and everythjngs closed?

Furnace vent pipe too close to the crawl space vent.

In my case it was the crawl space vent that needed to be blocked off. The exhaust is very close to the crawl space vent in the foundation and was blowing back in under the house and creeping into my house. My Dyson has a VOC sensor and it registered a very high levels of VOC. This has been happening for years and causing me health problems. Now that is is fixed I no longer have fatigue and headaches and a terrible rash on my arms has also disappeared along with joint pains. Is there a code that says the gas furnace exhaust should not be close to the vent?
