Thinking Wood Gun...any advice or experience?

[avc8130]

I stopped by the local heart supply. He instantly pointed me towards black double wall pipe. He suggested a telescoping length, 90 elbow and then a 24" length feeding into a 6-7 increaser. Total cost ~$400. The pipe he suggested is SS internal, black stove external.

Thoughts?

I have never used this telescoping pipe. So the telescoping just goes straight in and out. Right? There is no flexing it side to side or curving. Right?

Yes it is only an in and out adjustment. I used it on my set up. I put my thimble in the ceiling and secured the first piece of dbl wall ss in the thimble then was able to adjust the telescoping piece to the right length.

You can see that I extended it about 8 or so inches. You can also see the end of the fiberglass roping that I stuffed around the bottom since I didn't want to use any silicone so that it would be easy to pull apart. Which I have done several times. I have actually clogged the hole in the cone of the cyclone ash collector twice. How I don't know. Plus I have taken the pipe off to inspect it and it was just dusty, no creosote.
The supplier claims it is stainless on the inside and only black pipe on the outside. Maybe I will take it apart again(only takes 2 minutes) and see if a magnet sticks to the inside.
So hows the install going.

Mike,

Any issues attaching the double wall to the cyclone?

My money says a magnet will stick. Most use 400 series stainless. This series is generally magnetic and will rust on the surface, but takes an eternity to rust through. This is similar to what most auto manufacturers use for their exhaust systems.

No progress on my install. I need to figure out the chimney situation and then I will be ready to cut out the oil boiler and place the WG.

My boiler guy is busy converting the house he bought from forced air to baseboard radiators.

Trust me, if I have progress there WILL be pics!

No It has a twist lock connection but it just dropped on.
There is also an adapter to attach it to the ss dbl wall pipe. I think you can see it in the first pic. It's kind of a reducer.

Interesting

Maybe you could come out of the thimble with a 45* degree elbow then use the telescoping piece on an angle and then use a 45* elbow to connect to the ash collector.

I've thought about using 45's. They are a bit more expensive than a 90, but if I can save a length it would be cheaper overall. I need to come up 42" to the center of my thimble. I would like to be ~24" on my horizontal run.

I just used plain single wall black stove pipe & off the shelf T (to get a clean out) & cut the pipe to length with a grinder. If that doesn't last sufficiently, I'll replace with something more substantial - but I think it'll be good for a while.

I can't use single wall without some sort of shield due to clearances.

Mike. You probably figured this out already, but. If you plug the hole in the cone, which I have done many times, I just pull the ash pan out just far enough to get my hand in there and with a small screw driver clear the hole. This lets the ash pan still catch the ash and as you twist the screwdriver around it will start to fall in there until it is all gone.

Mike,

What brand pipe is that?

You are making this more complicated than it needs to be. Buy some black pipe a few adjustable 90's cut to fit and shield the pipe wherever it gets too close to combustible surfaces. Should cost about 50 dollars and take no more than an hour.

Trust me, I realize. The engineer side of me is the one having the confusion.

If it wasn't for Gassifier's post about switching from SS single to double for draft issues, and Wood Gun's own requirement for SS, this would be a no-brainer.

My fear:
If I slap it up with single wall black, I can do that cheap and easy. I will be "free" to make the horizontal run as long/short as I like. If I want to change it later to something 2 wall (for whatever reason), I will most likely need 2 telescoping lengths. One for the vertical (unavoidable) and one for the horizontal (avoidable by going to 2-wall from the start and placing boiler based on 24" factory length).

Can you just place the boiler for the 24" horizontal now, use black single wall, then your boiler will be in the right place if you replace the single wall later?

Also, I think Gasifiers chimney is all outside - is yours? I really can't see where that initial bit of pipe being single or double wall will make much of a difference there if your chimney is inside. Does Wood Gun call for double wall - or just stainless single?

I THINK I could do that. I priced single wall black: $215 for what I need with heat shield.

Double wall black: $320

My chimney is 8x8 masonry internal. It goes from basement where the thimble height is ~6.5', up through 1st story, up through attic (~6') and then through the roof ~4'.

That sounds like a lot for plain single wall black. The heat shield I got was $24.99, I think it extends to 4ft long (sliding sections). It's still in the box though. I know I got a 24in. piece of 7" black single wall that was $8.99, a 36in. piece of 7" was $15.99, a 7in. T was $23.99, and 8in T was $37.99.

I remember seeing it at Tractor Supply and price looked cheap. Maybe I'll take a ride back down there. I wonder if they sell the shield.

I just got off the phone with Darren at AHS. We spoke about the chimney requirements. He stated that double wall with a stainless liner would be my best bet.

The reason they suggest the heavy wall stainless is since there will be high amounts of moisture in the exhaust gasses that may condense and rot out single wall steel rapidly.

He said the insulation value of the double wall, combined with the SS inner should last a very long time.

I actually had puddles of water in the ash pan or real soggy ashes. I think my problem is the WG is in an unheated space except for what ever heat is created by the unit so I get condensation from the flue heating and cooling.

Did you get a chance to get the model number of the cycle timer and take any pictures of it?

You are also a straight up install. You could be condensing at the top of your run and it working its way straight down. That would wind up in the cleanout in the bottom of my masonry chimney.

I don't have the cycle timer yet. I referenced YOUR thread to help determine which one was right.

Not a whole lot to update. I ordered the chimney connection on Friday. It should be here tomorrow. Once that is in I can place the boiler. Trying to be cheap, I am using a fixed 24" length out of the masonry thimble so horizontal placement will be critical.

Thank goodness it is 70F here! LOL

Better get a move on. 70* wont last much longer.

Hey i got the smoke hood piped up I ran it out the side of the garage wall and I took the extension cord off and moved the switch to be mounted on the side of the unit.
