Has anyone used a chimney cap on their OWB? I tried one that was meant for the HM chimney and it made a mess of creosote run down the pipe. I had to remove it. I just wanted to keep the rain out, seems like every winter we get a couple of inches of rain. Had 2 weeks of rain this winter. Anyone tried one of the cloverleaf caps?
-
I was just wondering the same thing have my old cap from my old boiler was wondering if I should use it or not.
-
I can see possibly using them on a gasser but conventional style will typically plug up pretty fast, Wood Doctor had one that they used on their conventional that worked pretty well if you can find them but they were very expensive!
-
There is more moisture in the wood you load in the furnace then any rain that would come down the chimney. It'll steam out no problem. I only cap my furnace when the fire is out.
-
Put a cap on mine last fall and had it plug with creosote twice. Ended up removing the screen and the band around the middle. No problems after that.

I put a bucket on my stack when I'm done for the season. Never seen any signs that the rain that went down the stack when it was running did any harm. Slim asked me where the cap was that came with it when I put the pipe on , I thought that was a shipping thing , probably behind the wood pile I guess. Never seen any use for a rain cap when it is running.

Cap?
Ah…you mean the plastic shipping cap?
Five gallon bucket here as well when done.

Ha ha, I remember that, I try to remember to tell customers now to save it, just looks better than a bucket for those who care but hey if you're a redneck you might as well look like one!

The plastic cap that came with my boiler was nothing more than a plug. I noticed after I bought it that the plug filled with water and then somehow ran down the inside of the chimney and the whole inside was wet. I used floor dry to dry it out. I had the boiler about 8 months before I installed it and this was the first thing I checked. I removed the plug and put a pail over the chimney and it stooped the rain form coming in. Plug went in the trash. I only will use a pail in the off season. Thanks for the info on the cap. I guess I'll be running with no cap, sounds like using a cap is more of problem than a help.
-
Yes on the conventional they are more nuisance than good, I wish I could find the info on the ones WoodDoctor used, they worked very well!

Were the WoodDoctor one something like this? http://www.pioneermetalworx.ca/caps

I’ve seen a few of those clover leaf caps around. $$$
-
Yup, exactly the clover leaf one without the flat bottom, they kept the rain out with very little restriction, 12 years on my Wood Booger and never plugged once!
-
I'll snap a picture of the one I made for my G200 and post it tomorrow hopefully. Real easy to make with a little galvanized sheet metal. I did not have a cap on my G400 originally. We had a lot of rain last year, that along with the unit idling a lot because it was over sized and mild weather caused a lot of creosote to run down the back of my unit. It leaked out of the venter housing plate completely covering the back of the unit with creosote. Now I put on the cap if rain is predicted or the weather gets mild.
-
I think all the new ones have a lip across the access panel to catch water and allow it to evaporate. Mine is a couple years old and doesn't have the lip tho and it only dripped the first day or so. But a bigger unit would probably be worse.
-
Thanks for all the info I received. The Selkirk I bought at a cost of $70-80 bucks just is not worth the money. I have seen conventional Outdoor boilers with the cloverleaf, and was wondering if it would worth the money? Never had one on the old CB. Just though that since it has more bypasses, it might keep the rain out. This winter we got 2" rain in a week, and the HM didn't have to run to much.
-
I picked up a high flow rain cap from menards (don't know if you guys have these stores out east). Cost me 40 bucks. Has a little 10" hat inside a circle that covers the chimney opening. Never plugs up, never had rain in the stove even in the summer.

How does this cap preform when the stove shuts down? Any creosote buildup? The Selkirk cap I had on for a couple of months creosoted up so bad, I had creosote running down the chimney pipe, I have a 4' extension. Had to remove it. Just wondering if this cap is any better?
(Hope you can make it on Sat. Text me to let me know what time.)

Has anyone tried one of the directional caps that turn with the wind?

This cap works great on the off season. Had no signs of water in the firebox. I do however get creosote on the outside ring and it tends to drop little pea size drops on the roof of the stove but they easily brush off. At least it doesn't run down the chimney.

Would probably work well with a gasifier, would probably creosote up with a conventional and quit turning pretty quick.
I do take it you’re referring to one of these?

The cloverleaf caps are supposed to prevent down draft. I would try one of them first before a directional type.
The 6" Menards caps are not compatible with the pipe that most OWBs use. I have not tried an 8" to see if it would fit 8" ultra temp pipe.
-
The one I have from menards screws right on RSI. I think it's double wall socket typ. I did notice their chimney pipe is however somewhat larger around and that doesn't fit correctly
-
I will have to try it again I guess. I have one sitting at the office and I thought it was about 3/4" larger diameter than the pipe.
Is the pipe on your boiler Selkirk Ultra temp?
-
I'm not sure, I do know the menards pipe does not fit but the stuff from fleet farm is what I needed to fit. The cap however did fit. Not sure if the cap is more universal to fit both pipes. Do you know off hand what the pipe from fleet farm is called? That is what I needed because the menards pipe was significantly larger in size that the pipe would not screw into the pipe the stove came with. It's been a few years so I cannot remember.
-
I am not sure what Fleetfarm sells. Closest one to me is BeaverDam so I don't go there very often. Farm and Fleet is in this area and I don't think they carry any insulated chimney.
-
This is the cap I made. Very simple, works great and very inexpensive. Took some galvanized sheet metal and cut out a circle the diameter I wanted. Cut a slit to the middle and over lapped the edge pop riveting it together. Next I riveted on 3 strips of galvanized sheet metal as the legs. I made them plenty long so I could raise the cap as high as I wanted. Then I made a smaller circle for the inside inverting it, notching out tabs for the legs and riveted it to the legs. The inverted cone on the underside helps to disperse the flue products when there is little or no wind. I don't get any dripping from this cap but a gasser burns pretty clean. The cap is held in place with a stainless steel hose clamp at the top of the chimney. You can raise or lower it to any level you want and you could drop it right down for the summer if you wanted to.
-
Forgot to mention I used this same cap on the G400 I had last year as well as the G200 I have now. You probably would get a little rain in if it is blowing sideways but nothing like having a 6" or 8" opening unprotected. I think I have about $5 into it.

I tried the cap this morning. It is about 1/2" too big.

Looks like aliens are checking the exhaust gases.

Do u think I got an early model? Wonder why mine fit? That's completely odd to me.
-
Is there a label on the outside of your chimney? I think it is usually towards the back of the stove, It should be Selkirk Ultra Temp.
I think it was around the fall of 2014 that they started putting insulated pipe on them. Maybe they used something different if yours was one of the first with it.
-
I will check it out tomorrow for you. I'll see if I can get a picture. Not sure I've seen a sticker on it. It I could have missed it.
