Out temp to inside temp...

[touchthewindrider]

If the outside temperature is 93 degrees and the inside temp is 77, wouldn't it take a pretty hot fire to
be able to create a draft? (I would guess a fire hotter than 93 degrees? Of course.)

I'm trying to cure in some fresh furnace cement, and a new inner top plate, with a few small fires.
My small fires are not drawing very well and I'm getting some smoke back drafting through the
primary air control.

Please tell me it's due to the temperature deferential between the inside and outside air...and that
fires are too small to get the air flowing up the chimney. Say it'll all be okay.

Thanks,
Cliff

Yeah with that outside temp draft is gonna be a major problem. That and the atmospheric pressure on the East Coast right now is causing it.

Well, unless you have a chimney nicknamed "Stubby".

What is the chimney setup?

Yep, you nailed it.

That is simply too warm outside to try and play with a fire. I'm afraid you'll just need to be patient.

The fire for furnace cement is just to cook the moisture out of it. Any that is left will leave the area the first time you have a fire when it gets cooler.

I am having flashbacks to my wife's comments when I used to install liners or new stoves in July or August. "OK, it is about to get really hot in this place." Never could wait to smoke check it.

It's a hard urge to resist. Did the same in the middle of the summer when I put my liner in.

I was pleasantly surprised how well it drafted considering the temp. I'm thinking it was probably around 70 though. At 93, I'd be huddled in the shade somewhere hugging a cooler; certainly wouldn't consider an indoor fire regardless of the work done.

Also as I think back, I didn't try and build a really small fire. I put in enough wood to heat the stove up which might have helped too.

yeah yeah.....everything I was thinking. But, you know....sometimes you just NEED to hear someone else
say it.

I think the temp is suppose to change some in the next week....lows in the 60's at night. Maybe I'll give it another
try then.

Thanks all. Keep splitting....

Little Brown Haired Girl's best reaction ever was after I tossed the liner on the 30-NC after a year, long story, and replaced it in mid-July. Feet burning on the hot roof. When I got through I told her I was gonna fire the stove to test the liner and apologized in advance for the heat coming in the house. Her: "So? You're a wood burner or you're not. Light that big mofo off.".

Okay, a friend of mine sent this to me. Makes sense, but...wouldn't the fire have to be HOT enough to create the draft in the first place? I remember with fireplaces, at times I'd have to hold burning newspaper up the flue to get air raising to create a draft.

"No,the fire itself creates the draft,before air conditioning people would build fires in the summer to draw air thru an open house. The fire is causing the draft by using air to burn and hot air rises.'

Remember that hot air rises and conversly , cold air sinks. 93 out and 77 in sounds like you have the AC on. Your entire house is a negative pressure reverse chimney right now, adding to the difficulty you already have drafting in 93 degree heat.

I've always been amazed at the difference in draft going from 45 degrees down to 35 degrees, and then again down to 25, etc.

Considering how hot a stove gets, it's surprising how much draft is reduced by a 10,20,30 degree difference in temp outside, but the difference is significant (as you have seen).

Sorry but there's no fighting it, you simply need to wait for more appropriate temps and pressure.

Thanks for the feedback folks! I rebuilt the stove back in early June and have been splitting wood like it is
going out of style....I just want to make sure all is going to be well this winter..... too funny

Patience it is, then.
