combustion air intake

[jodil]

Its very common here to find combustion air intake for furnace room in basement. However, today I find one that terminates in attic. The furnace was missing both covers so lots of warm air was rising up the intake and going into the attic. Besides that factor not being a good thing, what other issues can you think of as to why this vent should not be in the attic?

Thanks

Hi Jodi,

What do you mean the furnace was "missing both covers?" Are you saying that the air handler cover was missing and that the cover over the combustion tubes is missing?

If so, that furnace needs to be shut down immediately and not used until the covers are found and reinstalled.

Other than that, a furnace can obtain combustion air from the attic as long as it's the local code guy allows it because the attic is sufficiently ventilated, and the manufacturer's specs allow it.

You need to get yourself a copy of CodeCheck Complete. There are some good diagrams in there to help you understand this stuff more easily.

Mike is right.

No, I meant the front panels on the furnace (blower area and burner area) the furnace was very old so alot of the heat was coming off the burners. I'll order the code check books.

Most of the combustion intakes that I have seen here (and I hopeIm using the right term) are made of aluminum accordian style venting going from outside to inside the room. I hadnt seen one in the attic before.

thank you!

Get the new Code Check Complete. It's all the books in one and it's nicely made and cheaper than buying the singles or sets.

I just purchased CCC to study for my state exam, and I am so glad I have it. It is so much easier to understand things when you have illustrations to look at. It will be a great resource for inspections, I'm sure. Also, the construction of the book seems very high quality (durable). Highly recommended! [:-thumbu]
