I had the bright idea that my friend could just buy the blower and installation boot from Hitzer and turn this into a forced-air furnace. But alas, Dean at Hitzer informed me that this isn't so easy!
That stove has to be around 30 years old. The only way to date it is if you can get the serial # off the thermostat. there is no way to put the blower and filter box on that stove. What that is is a black box radiant heater. We still make it today. The blower and filter box goes on the 82FA model which is our furnace add on. Basically we take the 82 and put a sheet metal shell around it to force the air into your duct work and then it is the 82FA. Even today you can't put the shell on the 82 to make a 82FA because we move the legs, weld mounting brackets on it, and move the air intake onto the back instead of the side. Hope this answers your question.
The customer service from Dean is extraordinary and they make great products!!
