Maybe a Stupid Question, But Can a Pellet Stove be Vented 30' or so Out the Roof?

Is this a no, no? I'm thinking of pellet stove appropriate vent pipe, and a basement location.
Thanks.
 
As long as its 4" vent... (and a straight shot) I dont know why it would be a problem..

This would be an interior install? Correct? Not 30' of outside vent going up the side of your house?

A basement install can go up the interior basement wall, punch out the Sill amd terminate 1 ft away from the siding? It doesnt have to be like a woodstove?

(Edit: pics added of my basement install)

some stoves yes, some stoves no...consult owners manual of the particular stoves you are interested in for exact specs. Harman current list the 30' limit with 4" liner...though in the past it was as high as 40' EVL with 4" pipe. The times they are a changin'
 
This would be in an insulated exterior chase.
I was looking at a Harman pellet boiler, (Hydroflex), and the manual had a pretty short length limitation; because of the low exhaust temps, supposedly.

Why go up that high? It only needs to be so far above the ground and so far away from the structure.

Its not a woodstove. It doesnt need to penetrate 2-3 ft above the peak (10-3-2 rule).

Keep the vent short and it keeps install costs down?
 
There things like windows and vents I'd have to work around. Plus, a pipe out the side of the bldg. doesn't look that great, although just as bad as the plastic pipe for the condensing gas units.

Will it go staight out of the stove - then into a Tee - and go 30' up ? If so then 30' with 4" should not be a problem.
Or do you require the use of more elbows then that ?
 
That'd be about it.
I hear the advice about consulting the manual though.
Out the side of house would be most cost effective, if possible.
 
I'm using a Hydroflex and have the 3" venting running about 25' horizontal w/ T for clean out. Burned 2 tons in it last winter and pipe was clean. The combustion blower helps keep a high burn so less soot, cleaner burn.
 
I did not see it on Harman's site, do you know if it is Intertek Safety Listed, A.S.M.E. Stamped ? You may want to check with your insurance company.

To answer your question, yes. I would also recommend it. A pellet boiler is not a pellet stove.
 
dont flat install to the outside. use the 1/4" per foot upward to out to help aid in natural drafting and then up. Like all things the 4" is set for the least amount of thought in install to aide in less consumer complaints and misshaps from poor instalation. Heat rises and slows as it cools, the larger pipe will aid in drafting as it cools is what a design engineer told me.
On that note mine shouldnt work acording to him.
