This requires a pressure difference to accelerate the gasses to their final velocity plus friction losses.The combustion of fuel requires oxygen called air, to move the required air through the fuel bed and to produce a flow of the gaseous products of combustion out from the furnace, to the chimney through the superheater, economizer, and air preheater.Furnace pressure is commonly known as draft or draft pressure or sometimes furnace draft.For the flow of Air and Fuel into the furnace and the flow of Flue gas from the furnace to the chimney. The driving force for this flow is the differential pressure between these gasses inside and outside the furnace.Considering Air and Flue gas Circuit, here the Air and Fuel such as coal or Bagasse are mixed and ignited in the combustion chamber at the furnace.Cooling Water Circuit Furnace Draft Control System.DO NOT LET THE COALS/ASHES BUILD UP ANY HIGHER THAN HALF WAY UP THE FIRE BOX LINER.A basic boiler system consists of various circuits such as When burning coal it must be set at maximum, for burning wood it will vary with size and type. Normally the setting is in the center between maximum and minimum, then if additional control is needed it can be adjusted accordingly. Set this slide plate to the position that allows sufficient combustion air in for the type of solid fuel being burned. The type of wood and how you stack it can impact heat level significantly.ĬOMBUSTION AIR CONTROL The amount of combustion air allowed to enter into the firebox can be controlled by means of the Draft Control slide on the draft fan mounting plate.
Collaborated draft control in furnance manual#
The manual is referring to a manual damper on the furnace that should be closed. AFAIK The only way to calibrate it property is with a manometer to test the pressure in the flue. This changes the balance of the damper which will swing open (this reducing the pressure in the flue) when draft exceeds the setting for the damper. You adjust the draft by shifting the position of the weight (it unscrews). If you flip it open you'll see a weight of some sort attached near the top side of the damper.
You have a barometric damper connected to the flue. Soot on the bricks is nothing to worry about.

I would replace the cracked ones as well. Get a measurement from ones that are still intact. I'm keeping the draft fan on practically all the time and burning seasoned hardwood, measured at <20% moisture.ĭefinitely replace the crumbling bricks. I'm wondering if the way it's set up right now could be contributing to less effective burning, since I don't seem to be getting much heat from the amount of fuel I'm putting in it, and I'm getting some smoke out the chimney. Is it supposed to be like this? Should I be doing something to it before burning wood? The manual says to "close it" in the case of a chimney fire but I don't understand how I would do that. I can't see any obvious way to "adjust" it and I'm not sure what W.C means anyway. Sometimes I hear it 'dinging' as it swings in the wind, on windy days. I went behind the furnace to look at it and it's basically just a hole in the side of the flue pipe with a very loose, flapping piece of metal. The chimney sweep who inspected it never mentioned anything about flue draft or damper. "If you mostly use the oil furnace and then switch to using wood, many homeowners forget to check their air damper on the chimney"Ĭheck it for what? The Newmac manual makes constant references to a 'draft regulator' or 'barometric damper' on the flue and says things like: I was reading up on oil/wood furnaces and found this article which contains this statement: (side question - is this level of soot build-up on the bricks normal after 2-3 fires? Should I be cleaning it off?)Ģ. Can I easily replace these myself? As long as it's the same size, is any firebrick material acceptable? I attached pics of before and after, I happened to take a picture of the firebox just after moving in, before I had Iit any fires in it. Only after he left, I realized the ones at the back kind of are crumbling. I brought it up the cracks to the chimney sweep and he said it's not a big deal as long as they aren't chipping and crumbling. The firebricks in the firebox look really rough. Now that I've used it, I just have more questions! I'm going to limit myself to just a couple for now:ġ. Just the other day the chimney sweep came out and cleaned and inspected the wood side so I've burned a couple of fires in it. So far, since it's not been that cold during fall, I've been just using the oil side occasionally (which was inspected and signed off on by a gas furnace tech). I've figured out that the model is the CL86/96C and the manual is actually available online from here:
I recently moved into a rural property and inherited the wood/oil combination furnace heating system. Hi all, new member and new wood burner here 👋Threads on this site have been really helpful so far!
