Wood Furnace Install

I am going be installing a wood furnace in my basement very soon. The problem i have is the plenum will be to close to the ceiling joice (needs a min of 6 inches). What could i use for a heat sheald to decrease the distance to combustibles.

thanks

How high is your plenum? If you have the room, cut it down a little.

My plenum is 24x24x24. Could i use sheet metel for a heat shield?

I used a 3x3 foot piece of thin sheet metal, drilled holes in the four corners and got ceramic insulators (the old style electric fence insulators) and screwed the tin up to the ceiling with the insulators inbetween. that gave me a 1.5 inch air space between the tin and the ceiling.

Inspector and insurance company gave me the thumbs up.

Thanks so much for the reply. I will try it out.

We had the same problem, just cut the plenum down by 6".

You done this before!
