Secondary air DIY

[DaveNY49]

I’m hoping someone sees this post who has done their own secondary air tubes and has knowledge. I’d like to talk and ask questions

Is this an older stove? Use the search function, I know there are some threads here of people doing this with their older stoves.

Post in thread 'Grandma Bear retrofit with secondary air'

Oct 10, 2015

If you put a shield on the stove back like a Grandma III you will have hotter intake air. Shield the bottom with opening in front, under ash fender, and up the back, open at top. (shown in VI manual) Your intake won't mix as much cooler room air.
Another way I've toyed with is a double baffle plate, (1/2 inch apart) hollow inside with air holes drilled in rows through the bottom plate. The entire baffle is a preheat chamber. (the hottest part of the stove) Pipe flanges on the top plate with 3/4 pipe going up the stack about 2 feet and out the side of pipe preheats it very well without...

Thread 'DIY Secondary Combustion / Air'

Dec 13, 2019

I want to share what I have learned from hours of reading forums and watching youtube - an attempt to repay those who laid the groundwork for me.

I have a Suburban Manufacturing Wood Chief / Coal Chief stove insert that has faithfully heated my house(s) since 2006ish. This is been a great stove, 4cf fire box, ash tray, two speed blower with snap disc, and two small windows.

The stove makes good heat but began to bother me with the amount of heat lost up the chimney - there are NO baffles in the stove. Not wanting to continue being wasteful I decided to buy a Quadra Fire in the...

Thread 'DIY secondary burn'

Aug 8, 2024

I’m seeing many people who have successfully made a secondary burn set up for their stoves. I just bought an old used Bullard stove. It has a thick (2 inches) hollow baffle. And comes with a blower on the back. If what I’m seeing in a secondary burn system is correct,…it’s basically air coming into the top of the firebox pushing down on the fire and burning the smoke and gases? I’m wondering if I could drill a series of holes in the hollow baffle creating secondary burn effect? And leaving the blower off would leave an opening for draft to he holes. Am I off on my theory?

Thanks...

Yeah I am not seeming to get solid detailed info no matter what I post or in the search unfortunately.

Yes. A fisher teddy bear and a Bullard. I was trying to find out the exacts of a secondary burn system As in the exact size pipe to use. How many holes. How far apart are the holes. What size are the holes. Is it one pipe or many. Where is the best position for them. Things like that. And if each stove needs its own particular system or would they all get the same set up

One of the thread links I posted earlier is specifically for a Fisher stove.
