Installing a cast iron flue dampener on a top vent pioneer?

PostBy: powderextreme On: Sun Dec 23, 2012 10:11 am

I have been throwing this idea around. I am thinking about installing a cast iron flue dampener on a pioneer top vent 3" up in the first section of flue pipe to help hold more heat in the stove. Its a old tri-burner stove with power vent. I can wash the heat outof stove with the circulation fans on high. The stove temp on low fan and feed is 170/180. The stove temp on high fan and high feed is 380/400. I can increase the feed stroke which will increase size of fire but I am burning more coal and can get temps in the 600's. My power vent can definetly over come the restricton of the cast dampener to achieve proper draft. I have a draft gage and I'm dialed right in .4"draft. Has anyone installed a hand dampener on a stoker to restrict heat going out the pipe. I don't want to contribute to global warming... LOl...

I would NOT recommend any restricting of a Stoker flue/vent pipe.

Leisure Line got it right :!: ;)

Natural Draft is the only place for Manual Pipe Damper (MPD) (cast iron flue dampener)

Even though you are measurng the draft at the breach you could have insufficient over fire draft when using a MPD. Therefore we reiterate "DO NOT USE A MANUAL DAMPER ON ANY LEISURE LINE STOVE, BOILER, OR FURNACE". It is admirable to want to extract every last drop of heat but this method restricts the flow and that will cause volumetric problems with the stove that are dangerous (CO can be release in the home). Best bet is turn down the power vent so you have sufficient draft without the barometric damper flap being open excessively. Also remember to check it at idle as well as at full burn.

Please, please do not attempt the use of a manual damper in any stoker, as has already been stated not a good idea. :) :stretcher:

Oops :oops: Should of said...Hand Fired...instead of Natural Draft

Thanks for the replies. I have bumped the speed down on power vent and still getting the dwyer fluid to crest an .4 " stove temps came up 80 degrees. I have installed a T with a end cap instead of a elbow which made a big change in draft. Now I can just pop off the end cap and vacuum out the fly ash. After burning 2 ton I had about a 1/8" to a 1/4" of ash in horizontal pipe. Is that about normal? Next year I'm going to add flue chains like my harmon stove to give it quick clean feature.
