I just got a fireplace insert that someone else was discarding. It is an amazingly well built custom insert that is about 20 years old. I have cleaned it up and repainted it and put it in place. However, I have not built a fire in it yet.
There is a box built on to each side of the insert. Originally there was a small squirrel cage blower in each of these, directed into the air jacket surrounding the firebox. Someone "borrowed" the blowers from this unit to repair another insert. There is nothing to size the blowers by, other than measuring and guessing at necessary CFM. The previous owner said that the old blowers were variable speend units. He said he usually kept them running on low except at night. Grainger has a variety of these type of blowers. The two that appear to fit have been discontinued. The new models that have replaced them specifically state that they cannot be used on seed controls. What appeared to fit was the 4c442 and 4c446. It appears they have been replaced by the 1TDP5 and 1TDP7. Both specifically state that they cannot be used with speed controllers.
HELP!! Anyone out there got any good ideas?
