Petit Godin 3726 - Flue Question

Very popular in the 70's and 80's there is many brands of smaller hand fired coal stoves from many European countries. These can also date back to the turn of the last century. Imported stoves would include such brands as Franco Belge, Saey and Efel among many others.

I have recently acquired a Petit Godin 3726 (small oval). The manufacturer's tag on the back states that the stove is rated as "au charbon" (for coal). It is in nice shape, but after I got it home I noticed that the exhaust box is sized for a 4" flue.
Now, I love the appearance of the stove. But burning coal is a bit of a problem for me. I was planning on obtaining a 4"-5" adapter, running 5" flue about 7' up to the ceiling, and then going to 6" for the last 8'-10'.
Will this work for wood, or will it just turn into a smoking dragon?
Any suggestions?

I have a 110 cm ( about 4.3 inch) outlet on my large round Godin. At the stove outlet I step up to a 5" flue. It is about 6 feet to the thimble where it enters a clay lined 22 foot long 8x12 flue. I usually burn coal but when I need a quick hot fire just to get the chill out of the house I burn wood. As long as your stove is still reasonable air-tight you can control the burn and not have smoke problems. The "air wick" behind the front firebrick lining introduces enough air to help control the smoke. Your 15' to 17' of 5" & 6" round should give enough draft for it to burn well if there are no other problems. The Godin is not the best wood stove, frequent reloads and minimal ash capacity, but it does burn cleanly.

I have the large oval, it has the 5" outlet. I have a 5 to 6 adaptor, use 6" pipe for about 2 feet up, then into an 8" thimble about 3.5ft horizontal, into a 20 ft 7x7 clay chimney. I think my stove is sealed pretty well, but if I try the newspaper trick, the paper just burns up and the smoke finds its way out of every crevice it can LOL.

It sounds like it should work although every setup is different of course. I find that with wood I have no problem at all getting enough draft. Some people have used hairdryers to get the draft going, I started using a propane torch to light and and start a consistent draft for wood, and avoid the smoke. I'm sure others have as well. Hope that's not considered cheating :)

You may want to consider a Manual Damper, especially for wood.

Another thing would be, when you set out to light a wood fire, get it right the first time with kindling, etc, as you really don't want to be opening your top door much at least for an hour or two. Once you have the stove warmed up, a decent ember bed on the grate, and the wood (1st or 2nd load) into a good burn, the draft could allow you to leave the top fill door open a little longer when refueling.

Average Time between fills is 2-3 hours.

You will find with wood, that you're getting a lot of heat off of the pipe, unlike using coal in this stove. If it's heating up too much, I sometimes put less logs in there and keep drafting it the same. Also using the manual damper.

Hope It works out!!!!!!!!!!!!!!

Hand Fed Coal Stove: Petit Godin

Post Fri. Oct. 14, 2016 6:55 pm

Hello:
Help! I have a Petit Godin and am having a hard time getting the proper stovepipe for it. The opening at the back of the stove is, as someone else mentioned here, about 11 cm or just over 4 inches. Does anyone know where to purchase an adapter to attach to that opening and fit at the other end to either 5" or 6" stovepipe elbow? I have a 6" diameter opening into the chimney at the top so will have to go to 6" at that point.
I have only been able to find a 5" to 6'" adapter. Also, the flue opening on the stove is designed with small tabs of metal protruding into its center, so I presume an adapter will have to fit around the exterior perimeter. Might there be a way to use a 5" wide adapter and modify it somehow to fit?
The other issue is I don't have a lot of clearance to the wall, so not much room for a large adapter, plus elbow. I had the stove hooked up adequately for years, with some kind of adapter, but old piping was removed and now I haven't been able to solve this problem and use the stove for about four years! I'm so hoping someone here can give me some direction. Thank you.

Normally, you try and keep the stove's breach size right through the thimble. I recommend going to your local HVAC supply house and explain your needs. They will provide you with a high grade commercial product at reasonable cost.

If your local supply house comes back a negative, and you can't find any contacts in France, you could probably fabricate one yourself by popping the rivets out of a piece of 6" stove pipe, wrapping it to the correct diameter, re-riveting it, then taking a 6" thimble cap, cutting a hole to fit your newly formed pipe, then connecting it to a conventional USA made chimney pipe. But that's just me talking outloud, and something like a last ditch effort.
(By the way, I'ld love to see a picture of your stove.) :)

If you can't get 4" from a supply house they must be closed. Most pellet stoves use 4".
