se iowa
hope some one can steer me the right way
I have a central boiler 6048 I am in iowa and in the middle of a 30 to 40 mph wind snow blizzard thing.
I checked my furnace and the water temp is at 200 and it is suppose to be at 185 when it shuts the draft off
I checked for ice build up on the draft door, it was closed and no build up of ice or creosote. I am holding off on filling it so i know i wont get to hot
Is there anyway i am getting a draft through the chimney during the shutdown process and that is causeing the fire to get air to burn.
There was a build up of ice around thethe bottom side of my door so that makes me think that there is a air leak at the door seal that may be causeing are to get in
PLEASE HELP
thanks ben

Could easy be the case. If you have any kind of air leakage from door seals or gaskets, a 30-40mph wind pulling on the stack will accentuate the problem. Keep an eye on your water level and keep the load size down just in case.
 
thats what im doin is there a water temp point that i should make a stop at and pull the wood out and get to coals
just dont want to hurt the invesment
thanks

does your draft door use a solenoid to hold it closed or only gravity? if no solenoid holding it closed, then the high winds could easily be pulling enough of a draft on the chimney to pull your draft door open. i've had that issue before on my heatmor
 
Have to think it is drafting through the chimney with those winds tonight. Best to remove as much wood as you safely can, let it cool down then add smaller loads until the storm passes. Best of luck. OWB runaways are no fun at all, awfully big tea kettle on a burner that is stuck on high.

Leaves one going :bug: that's what a 200+ gallon kettle looks like. Hope it does not boil dry warping would be very bad :-S . Like Heaterman said keep an eye on the water level, top up if you have to..
 
id love to put a cap on the chimney but 30 to 40 plus winds and a 20 ft chimney dont sound much fun at midnight
but yes i though of that i have let the load burn down and just throw in some small wet stuff for now. ill kep a eye every hour i havea temp gauge inside the house so its pretty easy to keep a eye on it
thank you all
 
Can you take heat off the OWB? If you have effective HX, I'd think turning up a zone would drop temp back down. Might have to keep turning up different zones till the wind abates. The good news is the house will be 80 °F . Should make the wife :cheese: and possibly :kiss:
 
When I was having boil over problems I was able to manually open my zone valve for the house (Taco electronic ball valve). I set the house blower to "on" rather than "auto" and let the house heat up big time. I got it up to 83 degrees the one time, but the boiler dropped it's temp to a safe range quickly and I didn't have any problems the rest of the night.

to funny! I think i'll throw some wood in the stove.
 
My Old Taylor 450 just had a flapper on the draft inlet with an exposed fan motor. I would have to lean a piece of Plywood against the front or right side depending on the wind direction. It slowed it down but would still pull across the stack.

The Barometric damper on my econoburn was getting a workout last night. But it held the draft to within specs. .02 to .05 if I held it shut it would spike to .15.

Would it work to use a Barometric damper on an OWB?
