fire goes out with blower

Hello, this is my first post and I would like to introduce myself by asking a strange question. I installed a 1978ish smoke dragon (honestly a fire dragon) last January. Its a Nashua wood burning stove. My father purchaced it new and burned with it a max 5 years. I decided to take it becouse it was collecting dust and oil prices were getting stupid. Stove pipe is 5' sigle wall, and chimney pipe is 15' triple wall duravent. The stove cranks, not as well as the newer epa stoves, but it cranks. 20 degrees out 78 in. We plan on upgrading when the economy gets better. My problem is when it is 2 below and i leave the blower on after choking the stove, fire goes out. If i don't have the blower going there is not a problem. The house is small 1100sq ft badly insulated cape. Stove is on the first floor, and the blower helps alot. Am I stuck with not using the blower and just use radiant heat? Using 2 year well seasoned maple, large coal bed, 300 to 500 stack temp before choking down.

I am using a thermometer, and packing the firebox, but i don't think i can give it too much more air, it will burn too fast for a overnight burn, from experience with this stove. What you say makes sense. I think becouse of the ineffiencey of the stove i am stuck with not using the fans. Thanks for the input.

BJ64 thanks for the idea. I will check on a reostat. If I can slow the blower down It may help. There is no need for blower now but it will help when the temps really get low.

Thank you Rick, I have only on or off with fans untill i can try to slow them down with a reostat or thermostat??

Good point Rick, I will check out Grainger supply. I believe the motor is a Dayton, I will need to do my homework. Radio Shack has yet to help. Thank you again for your help. I will continue with the trial and error untill then. I wish I found you guys a year ago. You have all been a great help.
