Hello all,
I recently got a used Pocono top vent. Having looked it over during disassembly for moving, it is clearly a very well designed stove, cunningly simple and effective. It has everything it needs with no extra or clumsy fluff.
Workmanship on the sheet metal is very nice, are these plasma/laser cut? Does not look like punch press work, or if it is, it is neat and tidy punch press work.

For my installation the stove is venting into a masonry chimney in the cellar by itself. The chimney is in the center of the house and 2.5 stories high. The house is one living floor and a full basement.

The flue piping would work out better if this stove was venting from the back/bottom.

I see a flue sized hole already cut into the sheet metal on the back, with a plate welded over it.

I am capable of welding at a professional level. In addition to opening the back flue hole and welding in a tube, What else is added to a back vent that is not in a top vent? I admit I have not stuck my head inside the stove as I am going to disassemble fully and clean it completely first. Then new gaskets, etc.

I suspect there must be some metal bar inside the back vent stove to prevent the ash pan being pushed all the way back and blocking the bottom vent hole. If LL would be willing to comment, and/or if someone with a back vent would consider taking a picture of the vent pipe hole area from inside the stove, that would help me a great deal.

Thank you,
Regards,

My stove is running at the moment but there is a horizontal 3/16" or so round metal wire that sticks out about 1.5" on the inside the stove for the exact reason you guessed. Mine has just enough room to get a shop vac past it. I've never seen a top vent up close so I don't know what else is different other than the removable top plate. I'm sure someone with more knowledge about both types will chime in soon.

Turbogeno, Thank you very much for that information. Do you recall if this rod right next to the flue hole exit, or way off to one side?

One other tip, make sure the flue outlet hole doesn't interfere with either convection fan or the combustion fan, we have on occasion plugged back vent inner backs due to hole mis-location (not Dave or I but perhaps the previous owner :lol: ). The ash pan stop is 3/16" wire with a 1" offset and the flue outlet is 6" tubing or you can get fancy and roll a flat sheet to make an outlet 6" OD instead of 6.25". Good luck with your project and thank you for purchasing a Leisure Line Product! :)

Matthaus,

Thank you for your input. I would not have expected that of the P.O. but I am sure you never would/have/will..never never. Just in case I will mock everything up first before I do any cutting. I do have the ability to roll sheet.

Can you tell me the significance of 6" OD vs 6.25" OD? Does tube stock only come in one size? I feel I am not understanding some important issue here. I was going to measure black stove pipe and size for that.

This is a really nice stove.

Regards,
404

Layed out the pipe cut out location on the back of the stove. Things look very snug when the blowers are in place.

Would it be possible for some one to take a pic of the back of their back/bottom vent stove to help me with locations?

There are too many possible ways to route the pipe and most of the ones I am looking at are probably wrong... Wondering if the flue pipe goes down in size and then expands again.

Thanks,

I have hyfire II which is back vent. there are some pictures under Hyfire II install, I used 6" stove pipe for everything, the first horizontal piece & 90 deg. elbow is where you have to watch for fly ash. the vertical pipe on my stove is 2 1/2 inches from hopper

The blower tubes are mounted differently on a rear vent Pocono vs a Top vent. I am not sure how much room you will have if converted.

I can get a pic of the back mine with measurements but not until the weekend. Clearances are pretty close.

Hi Hot Rocks

I did that the first time you mentioned it.. that is how I found the post I linked to. There are about 1540 results. I did go a few pages down. At 10 results per page that is 154 pages to read.

Now maybe I am lazy :D But could you narrow it down for me?

Image shows search results. update: image is screen shot of search results in google box on NEPA so I guess DO NOT UPLOAD COPYRIGHTED MATERIAL.
