the installation instructions it says to adjust the counter balance for desired draft, but what's the desired draft? what position should it be on when furnace is firing/not firing? thanks!

It's an oil furnace.

You are messing with something you have no business doing. You need a draft gauge to set it. This will also in turn require tuning the boiler to make sure it is burning properly. This requires the use of a digital combustion analyzer and someone talented enough to interpret and adjust it for the proper performance. Bubba

You might be able to find one on eBay, but this is what you need (and the knowledge to use it properly):

If you don't use one, you are just guessing so why not just set it at the halfway point. Keep you service guy's number handy...

Jenn, the pros will tell you you need an instrument to set this and they use one to do it. But as one home owner to another, you can roughly set it without a guage but err on the safe side and set it so that it is just closed when the furnace has been on for a while and everything is all warmed up. If you set it so it is closed too much, the only bad thing that may happen is you will use a small amount of extra fuel. If you set it so that it is open too much, you can get carbon monoxide in your house. So if you are going to do this, adjust the weight so that the flapper is balanced so that it is just closed during normal operation and only opens a little if there is a strong wind outside.

Well, as with everything else........there is a right way and a wrong way to do it. You have obviously been doing it the wrong way. I get paid to do it the right way. Customers appreciate that they arent wasting hundreds of gallons of oil per season because someone came in and "eyeballed" the adjustments on their system. Bubba

Completly wrong advice Mark. Having the damper closed while the unit is running allows the heat to be sucked out of the furnace too fast. Thus, you are heating the great outdoors and not your home. That little stupid adjustment just cost you hundreds of dollars over a heating season. It takes instruments and someone that knows how to use and interpret them. Anything else is just a guess. Bubba

Much better answer and hopefully to the benefit of the OP.
