It adjusted the door and seems to burn more wood.Next thing Ill do is make one that restricts the pipe down to 5''.

[MTJAG]

hey, let me know how that turns out.  I am definitely interested in a more efficient stove combination.  Are you located at a high altitude?

[woodywoodchucker]

I would say that im at 1500 ft or so. Nothing I have read or have been told except on here leads me to believe that it has anything to do with elevation.I do think that the restrictor would help due to the fact that all the non gasser boilers use the same stack.seems to me that a smaller boiler would have a smaller pipe coming from it.

[MTJAG]

Yea, it would seem to make sense that a smaller boiler would need a smaller stack.  I didn't get the idea that a higher altitude would necessarily benefit from a damper over a lower altitude.  Higher altitude has thinner air, so a restrictor would make it really puff for air it seems.  Then you have the issue of cresote build up I suppose.  We'll see when I get my 5036.

Just my .02 - The restrictor T would prevent overheating, thus wood usage. Although elevation is not the main factor, pressure at higher elevations are. For example:

At 7000 ft, the standard barometric pressure is 23.088 inches Hg, and so water boils at 199.3 degrees Fahrenheit or 199.3 °F, which is equal to 92.94 degrees Celsius, or 92.94 °C. However, the pressure at 7000 feet will not always be exactly 23.088 in Hg (for instance, if a weather pattern changes the barometric pressure). It is more precise to specify the barometric pressure and ask the boiling point. Here is an equation to calculate the boiling point of water at any barometric pressure:

boiling point = 49.161 * Ln (Pressure in inches Hg) + 44.932

(where "Ln" is the natural logarithm in base e)

What does this baffle look like and where does it go into the chimney? Any one have any pictures to show?

Thanks,
I see, it's just a reducer.

[MTJAG]

Just got delivery of my 5036 unit today with the baffle.   By the way, the baffle is just inserted in the pipe and is a reducer from 8" to 4".  According to my dealer, another dealer has put them in the last 28 or so deliveries of classics and with the exception of one customer with a 6058, all have reported longer burns, less wood consumption.  The downside is the also report more smoke when they open the door.
I posted a picture of it in my gallery today, so you can see it in place.

Did you look atthe restrictor?can you masure the i.d. and o.d. of the restrictor.Ive been told that it reduces the pipe down to 6 '' and now your saying 4 ''.If you could measure it we would all know. Maybe you already have .Thanks

[MTJAG]

The baffle is 4 5/8" inside diameter and 7 5/8" outside diameter.  I put a picture up in the Gallery of it inside the chimney.  Also, Ridgekid put up some info on barometric pressure and altitude that discusses how it might help to reduce the risk of overheating and thus wood consumption in a previous answer to this question.  Pretty interesting.

Finally got my 5036 going today.  I was having trouble getting the temp to 185 and couldn't for several hours.  The dealer told me to take out the restrictor to see if that would help bring up the temp....took it out and left it out for  three hours...no change.  I put it back in and fill the box and the temp started to climb.  I guess the mistake I made was not building a big fire to begin with.  Initially, I just built a small fire with limbs.  Anyway, we are cooking now. 

[woodywoodchucker]

How long or deep is that baffle?

[MTJAG]

the baffle is 7" long.  I took it out today to see if that is what is causing the creosote build up inside the unit.  I had to break it free of the creosote surrounding it.  Also, I am getting alot of smoke out the door and my dealer indicated it might be due to the baffle.  So, I thought I would experiment to see how much more wood it uses without the baffle.

[woodywoodchucker]

Cool keepus posted. Ive found that if you open the door slowly it scavenges the smoke from thestove.You can get smoke from the stove without the baffle, if you open thedoor right after the damper closes.
