Greetings folks. I've got Doug at Barnstable Stoves restoring a Glenwood Baseheater #8 for me and I've got some venting and placement questions for anyone familiar with this stove. How far out from the back wall, (brick), did you need to place it to make the connection to the thimble ? How high up from the stove is the ideal location for the thimble thru the wall ? What are your feelings on the best flue size dimensions in a brick/block chimney for this particular stove ? And finally what is the stovepipe size for this stove ? A lot of questions I know, but, your help is greatly appreciated ! Also, if anyone has some of the old advertising literature for this stove I'd gladly pay for copies. Thank you everyone, this is a great site !

Welcome Oldmanstyle,give it time(you ask and they will come) there are a good group of guys that have Glenwoods and will love to help just be patient.If you get some time look on YouTube under coal stoves and see the videos that some of the members posted,William has a good set of vids on running his Glenwood.
Take care .Keepaeyeonit

I'd give the stove a good 18 inches from the back brick wall, further if you want. I don't think there's an idea location for the thimble, that stove has the pipe come off at about 30 inches up from the floor. On my stove I go straight back to my tee for my chimney. I go through a fireplace. I've had this stove with the pipe going:
straight back;
straight up;
up to a thimble about 4 feet up;
up about 6 feet, right for about 4 feet and then back 6 feet to a chimney thimble.

Worked fine in all configurations as long as you have good draft. The stove takes 6 inch pipe. I like running 6 inch chimney pipe also.

Don't make your chimney flue too big...

OMS, Congrates on the aquisition of a fine heating stove. The Glenwood family just keeps getting stronger. The following is a link that you might find interesting.
Installed Our Glenwood Base Heater No. 8 This being the same stove installed a month or so.

As regards your thimble placement, you can as DJ mentioned, install it where ever you like it best but only avoid an area that is directly in back of a fireplace in the opposite room since the flue would narrow at that spot. Even there you could just move it up to where the flue opens up again.

Thanks everyone !

Ok fellows, my mason is telling me to put up a "standard" 8x12 brick chimney and not to fill the air space between the flue pipe and brick with vermiculite. Chimney is going to be about 23 ft. Opinions please.

I would prefer 8x 8 inch preferably round for best draft. Why put up an oversize chimney for a stove with low stack temperature?

Oldmanstyle,I am not a mason but I relined my chimney with 12"x 12" liner now I wish I would have(and still may next year)put in a 8" round liner(but thats my stove outlet) and filled the air space with vermiculite because the flue burning coal is a lot cooler then a wood fire and in warmer temps my draft gets low ,if I remember someone saying that round drafts better then square or rectangular so someone correct me if I'm wrong.Keepaeyeonit

too late franco beat me to it.

That seems like a large flue for the stove in question. My preference is 8" round tiles, they draft really well.

I don't know what the flue size is on the #8 but a 6"=28.3 sq in 8"=50.3 sq in,if you put in a 8"x 12" or (6.5"x 10.5' id) that is 68.25 sq in which like Rob said I think is to big but not knowing the flue size I can't tell you.

8" round with vermiculite it will be ! Thanks !

Now hold on ,I'm on expert on this so get some more feed back before you jump the gun,this is my opinion and we all know that they are like *censored* everyone has one, but wait more will chime in on this one.Keepaeyeonit

Yes sir, you are right. Nothing's going to be happening till next week. More opinions welcome !

The closer the chimney flue size is to the stove pipe, the better. A Glenwood No 8 takes a 6 inch pipe. If you can't get a six inch round flue tile, then I would opt for the 8 inch round. Also round is better than square. A round flue will facilitate more efficient drafting than a square flue. I know that most chimneys have square or rectangular flues, but; none the less a round one works better with a stove.
