Title: CB - E-Classic 2400 - Temp Setting and "Back Draft"
Post by: Ken01 on April 12, 2012, 12:46:43 PM
New to the Forum, but it seem informative based on what I have read so far

Ran a Classic 6048 for 5 years and this past year converted to an E-Classic 2400.  Have two questions if anyone has a thought.   1)  Digital temp reading on FireStarter Control Panel is 15 degrees warmer then water coming out of furnace - this seems odd to me.  CB dealer change the control panel and the difference increased to 20 degrees.  Have tested the water at the water level check value on the back of the furnace and on a in-line thermometer I have.  With the 6048 I had a 2 degree differential but now a 15 degree.    I have to run my high set point at 190+ degrees to keep the water in the furnace at 175 degrees.  Is this  normal ???      2)  on the E-classic the air blower is in the back with three solenoids opening air flows.  On occasion I find the air blower / solenoid area has been "back drafted" with a grey ash.  Can not figure out what set of conditions cause this "back draft" to occur nor have I ever seen or heard it happen.  Anyone else experienced this?

Ken, I would confirm that you do not have a pump reversed. Check the flow direction arrow on it, or check your owners manual to be certain your supply/return lines are not hooked up backwards or into the wrong ports. A 15-20 degee difference sounds like you may be pulling off the bottom and returning to the top of the water jacket in the rear corner above the pump mounting area, while your Firestar controller is reading from the top front right. That would be the only explanation I can think of.

Regarding backdraft dust into air intake box, I think I have had that happen if I let my coalbed get to deep in the firebox so it does not draw down like it should.

Converted from the 6048 due to neighbors concerns about smoke.  The E-2400 smokes a lot less and is using less wood over all.   I loved the 6048 and it worked well.   If it wasn't for the smoke / neighbor issue I would still have it.

Good suggestion to check the water flow.  I believe it is right but I may just reverse the pump and see if that changes temp. 

I will keep an eye on my coal bed and see if that has an effect on the backdraft dust.   I try to let it burn down before adding wood but my schedule does not always allow it so could be on those days when I add wood to soon this is happening.   Thanks for the thoughts.

Ken,  For my E1400, the manual says to wait at least 15 seconds before closing the by pass door after stoking the fire box.  If you do it sooner, smoke and creosote may gather in the primary solenoid and air box area.  Roger
