Cold air return

Time constraints after just moving and running out of firewood i finally got the keystoker 90 setup the best i can for this year. I understand its not ideal but hopefully keeps us from freezing. Its in the basement.
As of now its not hooked into ducting but i did run a cold air return from 1 bedroom to the stoker.
You can see in pic. Do i need pipe right up against blower or will this setup still suck the air from pipe or not close enough and will just suck basement air?
Thanks

Air will take the least path of resistance and pull most of it from the basement. Cold air drops and some air will come from the bedroom however nowhere near what your hoping for..

I heat a 80x30' top floor and warm the lower floor of a building with this stove. I changed the one dist. blower to a 460cfm fan (the biggest I could fit). A 8" top vent runs up to the 11' ceiling and across to the kitchen where there are 2 ceiling vents. I run an ultra quiet 6" fan from the end of the kitchen under the floor and back to the general stove area. I increased the stove BTU output by drilling three extra rows of 1/8" holes in the stoker bed but left the comb. fan size the same. Perhaps it now puts out 110K. Why not get a double walled 110k stove.... Don't need it. The chimney going up to the 11' ceiling extracts as much heat as is practical and I can't afford the purchase and install ... my wife needs a new saddle. Orrrrrr. a blower on the Mustang.

Blow it out ... suck it back. Quiet and cheap.

It will sure get tested this Thursday as lots of young ladies on Macys day floats have their mammary glands frozen off.

PS. the building is very well insulated.

So im trying to tie my keystoker 90 into the furnace. Heres a pic of the oil furnace I want to build an attachment on top of stove and connect into the 12" port on side of furnace plenum and use furnace blower to circulate heat. Something along the lines of that rough drawing.
The stove has a 500cfm blower. What would ideal size be from stove to furnace ducting? Its about 7ft away in length.
Using the furnace ducting will circulate the heat and bring air back from cold returns but i wont have a cold air to the stove blower. How best can i tie that in? Would a section of 8" pipe from one cold return register to blower be enough?
Thanks...can provide more pics if needed to understand. Im just going off my limited knowledge and forum reading to figure this out.

US Stove has some good and bad examples to model after. Look for their manuals online.

Connected the way you describe it, I'm guessing that the furnace blower, being much larger than the stove blower, will actually blow air INTO the stove. When the furnace blower is operating, it pressurizes the ducts and flow results. That pressure will overcome the much lower pressure produced by the stove.

Thats what i couldnt decideif would happen.
So you have to connect to the cold return side of furnace then?
And make a new cold return for stove?

Here's a summary of my experience connecting my Koker (160,000 btu) to my ductwork.
Post by CoaLen - My Koker Experience (So Far) II
My convection fan is rated at 1529 CFM so it's an apple & oranges comparison with your 90. I found the Koker performance resulting from connecting the heat duct into the cold air return to be unacceptable. I am aware that this is shown by some manufacturers to be a recommended method. However, it appears to me to be the simplest way, not the most efficient. Connecting into the plenum and cold air returns is more complicated because it requires baffles in both systems to properly separate the stove from the furnace.

Usually furnace blowers are much more CFM than the stoves, trying to make a stove into a furnace sometimes doesn't always work. but it been done successfully on here by a few with some good modifications. not sure if your stove has a jacket on it or just pulls air from back and top like most stoves. the 500cfm thru your ductwork may not push enough air to keep it up to temperatures. you may have to try it a couple different ways, if you use the furnace blower to PULL the air from and around the coal stove it might work pretty good. but too much air, will not heat up enough and may just blow cool to warm air. thats the way some of the other mfr's have them installed and not use the blower on the stove.
unless you can plumb it into a couple separate vents to upstairs or have some type of baffle to block off air going the wrong way in your furnace and tie it into your duct work.
