Godin 3720 heat shield

PostBy: GodinMan On: Wed Oct 24, 2012 11:27 pm

Hello,
I recently completed a rough installation of my new Godin 3720 inside a sunporch addition to my home that I am presently remodeling. The installation is fairly atypical as it will be placed in a corner inside a room full of windows. Does anybody have any insight to offer as far as heat shielding as the top of the stove is roughly 6 inches taller than the bottom of the windows behind it? In addition, it has a "manifold" at the rear of the stove with an upper and a lower connection. I attached the stovepipe to the lower connection and the stove appears to burn well. Does anybody have any insight into my installation? Recommendations will be greatly appreciated.
Thank you,
Joe C.

Here is the location of the stove. What would you do?

This is the present state of installation. Definitely not ideal location but it is what it is...

Why not kick the stove out from the corner and disregard the chimney jog?

The room is fairly small. The only reason I did not go straight up from there (it is a new chimney installation) is because the main hip rafter is directly above the stove outlet. We needed the fairly significant jog so the chimney pipe did not interfere with the hip rafter or the ridge shingles. By necessity we had to offset the chimney two rafter spaces from vertical. The sunporch addition is small, 8 feet x 16 feet and moving the stove would put it in an awkward position. Furthermore, the chimney location is barely outside of the 10 foot minimum distance from the main two story house structure. If the chimney was along the other wall in the pic I would have had to go up another 16 feet or so. I did not want it to be so high that it would require a beacon light!!

That stove looks like a Petit Godin 3726 or 3732 depending on the year it was made and if it was made for the North American market (3732) or an imported French stove (3726). There should be a plate on the bottom back of the cylinder with the model number or the model number should be on most of the cast parts...

You can use either outlet. The lower one is great when going out through a low fireplace opening. It also keeps the heat in the house a little longer before it goes up the flue. The lower outlet does have a tendency to clog with ash. If you draft slows down check it and clean it out.

The manual, in french, is located here:
http://www.godin.fr/notices-siteweb/372 ... 38B-05.pdf

A chart of clearances as supplied by Drolet, the North American importer of Godin in the 80s and 90s, is attached. The only way to reduce the clearances is with an approved heat shield. The heat shield would consist of non-combustible material spaced one inch from any combustible material with air space on the bottom and top to facilitate cooling air flow. See the Reduced Clearances section of the chart.

I cannot tell for sure from the picture but it appears that the stove is too close to the walls and windows. If it is burning hot it may cause problems including softening the window frames and eventually overheating the wood...

Bear in mind that heat shields need not be attached to a wall. A metal screen placed between the stove and wall will also serve. A half circle could look good with a little decoration on legs and frame such as fireplace screens have.

A half circle will work but most insurance companies and local code enforcement authorities (if there are any in your area) will not accept it if it is not permanently affixed to the walls and or floors.

The clearances on the pipe all the way to the ceiling should be addressed also...

Thanks for the input. It is located very close to wall and window and I would like to comply with the strictest standards of safety. As of now I plan to attach the heat shield utilizing spacers. My plan as of right now is to utilize cement board on each wall behind the stove with slate tile applied. Much like all of my other plans for the house the current plan will probably undergo some modifications. I don't like the idea of the heat shield being taller than the bottom of the windows but safety comes before beauty. In addition, I will apply a heat shield to the stove pipe so the hot pipe and windows can safely coexist in such close proximity. I know that this installation is far from ideal and the last thing I want to do is die in a house fire!! I don't want to cut any corners when it comes to safety...

Thanks,
Joe
