The built in blowers on the Hyfire are probably not powerful enough to overcome the resistance in your ductwork/filter.

What it's doing is the flow is going all over in your ductwork by trying to push it from the Hyfire, it's probalby going the wrong way into your cold air return ducts, that is why they recommend using the furnace blower to suck the heat and cold air the correct way thru the duct work.
Thanks Dave. I am going to give it a try now. I think you are right about the air going the wrong way from the cold air return. It is definetly not going into the furnace. I will let you know the verdict.

I turned on my furnace blower and there seems to be a couple problems. It is only blowing out of the returns in my house. The returns are closest to the furnace in the basement.
The second problem is the air coming out is luke warm.

How can your furnace be blowing out of your returns??

How hot is your stove running when the blower is running? if its not running hot, you may only be blowing luke warm air, since your furnace blower is much more powerful, it is washing off the heat too fast.

One of the first concerns with my customers is that the air comming out of the registers is luke warm. People are used to hot air from their oil furnaces. The beauty of the coal stove is that it is a constant heat. Once the house and all it's mass is heated to your set temp the Col-trol will do a great job of maintaining it. Make sure you don't have to many cold air returns feeding your oil furnace as this can wash alot of the heat from the coal furnace. The reason Jerry tells you to go to the cold air side of your oil unit is two fold...first the air from the Hyfire will go through your filter in the oil furnace removing dust and what not....second it is so much more efficient to pull the hot air off the stove than to try and push it. Hot air naturally wants to travel up, this is why the hot air jacket is designed to be open on the bottom. This allows air to flow freely around the stove washing as much heat from the stove as possible. I have customers that have tryed to run the hot air side of the oil furnace through the Hyfire and up into the house...it works but is supper ineficient. So just run off the hot air jacket into the cold air return on your oil unit and put a fan limiting switch about 18 to 24 inches from the Hyfire in the duct and wire it to your oil furnace fan. Set the low setting at 110 and the high setting at 140. Your furnace fan will run alot durrning cold snaps but it will be well worth it. Don't look for hot air , you won't get it. When you get it set up correctly, give it at least a day to adjust. Hope this helps.

This post sounds exactly what my experience has been so far. I know this is an older post but figured I could share some of my experience in my house.

My cold air return duct (there is only one) is 8x30 inch square. As my furnace fan was pulling the hot air off of the stove I noticed that the ducting was getting cooler and cooler and the output from the furnace was actually not luke warm but cold. I completely insulated my cold air return duct and that helped tremendously. The air temperature from the floor registers went up 10 to 15 deg.

It doesn't seem to heat up the house from 62 to 70 as quickly as the oil furnace does but it seems to be maintaining. I continue to have my own set of issues that I'm "working" through. I may start a new thread!
