Outdoor Furnace Smoke Stack Questions
« on: November 17, 2008, 10:09:54 PM »
My CL6048 has two sections of smoke stack.  I think they're 4' each.  I also have a spark arrester cap on it. I removed the wire screen to prevent creosote from clogging it.   The dealer charged me $85 for the cap.   I'm getting a lot of ground level smoke. 

Will removing the cap help prevent this?

Should I consider adding another 4' section of stack?

Should I put the cap on if I add the extra pipe section?

If I add another pipe section is guying necessary?  The manual recommends adding guying if more than 3 sections are used.

We use two sections of pipe with no cap or screen.  The smoke disipation depends a lot on the wind characteristics of your installation site.  Are there any buildings or trees that are interfering with the wind pattern?  We had a large white pine in close proximity to our stove that would occasionally cause an issue.  Since I removed it we have not had any issues.

I have a CB 5036 and my dealer told me not to put a cap on it so the smoke will dissipate better. When the damper opens, it looks like a 600 Cat or Cummings the way the smoke goes straight up. I have friends that have caps on theirs and they hold the smoke down low and get creosote real bad. My dealer told me to just cap the top with the plate that came with the chimney when the furnace is not in use.
