Ok I just got a hotblast 1400 works great but the blowers will not stop running. Now it don't come on as soon as I plug it in. But as soon as the fire get hot they come on and will not turn off until the fire is about out. At one point I touched the stove and it was cool and they were still on. I have unplug them and plug them back in. They come back on. It is the thermostat that came with it. Thank you
 
Hey Badwood, got same burner you have and this is typical of the thermostat located in upper rear corner. Till I got everything set I had to take off the cover and adjust settings till I got it close. I say close since this “thermostat” is pretty loose in terms of on/off-off/on function. Main thing I would check is that the thermo springs are not broken or micro switches not functioning. If you are already getting on-off functions then that is a good thing.

New or used? I got mine used, replaced some fire brick and grate and been feeding it maple and cherry with great results:chainsawguy: Good luck keep warm:smoking:
 
That is typical operation of the thermo snap disc that is shipped with the unit.
You could replace it with a unit similar to what is used on an oil or gas furnace plenum, the probe part needs to be at least 6" long. There were several posts about this in the past including mfg & models #s
 
Remember the blowers on a wood furnace serve two functions. First is to provide heat and the second is to keep the furnace from overheating. As long as the furnace is hot, the blowers will not shut off.

As stated above a limit switch can be used instead of your snap disc for regulating the fans more efficiently. They have adjustable settings for turning the blower fans on and off.

Dont think so= EPA furnace will have lower temp limit designed so that it maintains a certain temp for EPA pollution requirements.

ok I just scanned the manual...looks a lot like ours.

The fan and limit switch should be mounted in the hot air plenum ,although it does not give you settings..we set them for 125 off/150 on/ high limit 250.

If your runnning a snap disc...replace with a real fan control. The manual calls for a Honnywell fan & limit like what we use.

Your thermostat should be wired to the 60 cfm draft blower.
That blower should only operate when the stat is calling for heat. The big blower should only cycle when the heat builds in the plenum to the point that it triggers when it reaches the on setting.
 
2 different firebox configurations may not may not have the same hi/lo thermostat settings. If the furnace has a pre-determined hi/lo setting, altering the setting may void UL listing because UL never tested the furnace with the new settings,eh?

Pook why don't you take some time and go read that manual like I did to help this guy out instead of just balabbering your whimsical nonsence.
Once again we see our lovable flaming Pook spew his ignorant diseminations.

In fact the manual does not give settings...it only describes what a fan and limit switch does. EH!

MY BAD! OP take note if adjusting set points on adjustable thermostat, read the disk where it says DONT TURN DISK WHILE MOVING THE SETPOINTS i think.
CK, u sure do respond to my flawed post, thanx, now HOW ABOUT POSTING SMOKE ANALYSIS #S FOR THE YUCON?=excess air, CO content, prescribed criteria for EPA approval?

So what EPA standard would you like me to spend 500,000$ on to have our furnaces tested too?
The answer is there is no EPA standard to date. There is a proposed standard due to be intiated 2012.(B415)

Her again Pook your just a freakin troll...

I spend $100 to have an oil furnace tech tune my oil furnace & he analyzes the smoke for excess air & CO content. U cant do the same?
 
I believe the 1400 hotblast is the simple one in the line, if so it ships with a snap disc for the plenum blowers, the draft blower is an extra, it would be regulated by your wall thermostat. Also the snap switch is not mounted inside the plenum on that unit but at the top left hand corner on the exterior in a standard electrical box. Internally it is just a bi-metalic set of contact points, they do go bad, preset for range from the mfg of the switch.

Pook,
You need a full blown lab with thousands of dollars worth of sensitive testing devices. Then you do a whole regimen of testing.
That's for solid fuel...go read the B415 testing protocol.

When you do oil that's simple...any bacharach tester can determine CO and draft speeds.
Again you don't have a clue.....

Dang...feeding the trolls again.

Now I don't want to hear squat from you until you read this whole standard ...http://mha-net.org/docs/CSA-B451b.PDF

there will be questions to follow.

Got a full EPA results to post? or not............wouldn't that have some details?

If i made a burner, Id burn it to its sweet spot & then pay $100 for a 3rd party / oil tech to analyze the smoke.........why not?
 
It's not an EPA standard yet Pook.
I'll tell ya what you pay the $500,000 and I'll give ya all the data you want .

I give up Pook ...ya got me all tuckered out with your idiocy!

So I assume that I can have the smoke analyzed from my 35 yr old oil furnace but u cant do the same for your new EPA YUCON FURNACE? WHEN BURNING AT ITS SWEET SPOT. costs me 100$ to test for EXCESS AIR & CO CONTENT
 
First thanks for all the info I tried to post a pic of my thermostat. But cant so hear is the info on it (314631 ; t-o-d60t12 ;80314 ; 0932 ; F 120-30F .The furnace is new / iam not sure what a snap disc is and where to get one. And would the snap disc work better then the one I have plus how can I check my old one.
thanks
 
Call the company. If the snapdisc is faulty, they will replace it. If you want something that you can tweak your on and off with your blower, then a honeywell limit/control is what you need. Years ago the furnaces came with one, but then they got cheap and now use snap discs. With a honeywell, you need one with a 5 1/2" insertion.

I think you may have got lost in this thread, a soap opera seemed to break out. Below is a picture of the Honeywell limit switch on my furnace (different manufacturer). You can see the three little silver needles sticking out at 100,
150, and around 200. The middle one at 150 tells the fan to turn on when the 6" probe (not visible) reaches 150 degrees. As the furnace cools down, the round dial turns counter clockwise and follows the temperature down. When the temp falls to around 100 (where the first needle is set) the blower fan shuts off. And the third needle at around 200 will shut off the draft fan on my furnace if the furnace it getting too hot. I dont use the third function.

The function of a snap disc is basically the same in principle without the ability to adjust the settings like the limit switch above. My wood furnace never had a snap disc so I'm not too familiar if there is another function they provide. My previous wood stove had a snap disc which worked great. It turned on the blower when the firebox was hot, and shut off the blower when it cooled down.
