What is this cold air thing for?

[firebane]

I realize that this thread is a bit well old But strangely found it through Google so feel like just add to it.

Was in the basement the other day and found that this same contraption was dumping massive amounts of cold air into my basement. Now I know the furnace room should be sealed off and for the most part... it is.

But someone recommended putting a Hoyme damper in and wondering what the thoughts and feelings are on this?

I can actually feel cold outside air being dumped through the air vents in various places in the basement so would like to have this stop.

Your picture is inconclusive.

Put the intake into a 5 gallon bucket, leaving a 2-3" gap a the bottom of the pail.
When cold air is required it will take it from the bucket, and the pail will contain the cold air

How old is your furnace...

I believe if its Mid / high efficiency it should have a dedicated PVC line direct to the furnace.

2 actually...one for combustion air...one for exhaust.

Only a high efficiency unit will use plastic.
