thanks everyone....I'll check the draft!
Coalkirk...how often do you clean out that horizontal pipe? Mine is probably 6 or 7 feet long!!!!!!!!!!!!!!!!!!!!

byrdy, this may seem like an odd question but, are you using rice or buckwheat size coal?

OK, thanks just wanted to rule that out. Keystoker has reported problems with running buckwheat in direct vent units.

I remembered one last thing for you to check. When you are cleaning out the fire box, make sure you clean out the tube for the limit switch. Just use a shop-vac and get any ash out of the tube that might have clogged it. A clogged tube can lead to the reset button being tripped.

Brdy,

My horizontal pipe is less then 2' and then the fly ash can fall into the bottom of the chimney. I clean it twice per season.

my chimney

Ok, this is an ignorant question, but, I went outside and took the cap off the chimney (it seems like a cheesy chimney cap)....and that's when I realized that there is no 'bottom'on the vertical pipe that the chimney cap sits on! Is there supposed to be? Why would there be no bottom? When I took the cap off about a tablespoon of fly ash fell on the snow...is this why? So soot can just fall on the ground?

And REDMAN...where/what is the 'tube for the limit switch'??? I just read your note this morning....wish I had realized this last night. I cleaned everything and fired it back up already.

My last and final bothersome question.........what type of chimney caps do you all have?????? I need something different, this is for sure. It's too 'open'......I looked in my shop for some type of metal flashing to kind of elongate the roof of the chimney but couldnt find anything. I almost think somethign like a big inverted funnel would work. Any thoughts? I guess i should just look for a different type of cap for the pipe. Can I find a new cap at Lowes???? Ok, now i am just babbling.

Below is a picture of the switch/tube I was talking about. Look on the inside of the fire box, on the side where the switch is, and you will see where the tube comes into the firebox. There will be a big nut on the end of it, you cant miss it. Dont worry you can still clean it out with the stove lit, it just a little hotter for you.

I'm sorry, I have been calling that switch a limit switch, it is acually called a fume swich. Sorry if I caused any confusion.

A suggestion

PostBy: nwaelder On: Wed Feb 07, 2007 11:43 am

1) I don't believe you stated that you have a barometric damper installed. A barometric properly setup will relieve the excess draught caused by the wind causing high pressure at the chimney exit.

Installing a barometric damper coud be done today (assuming you had one). It would take a pair of tin snips and about 15 minutes.

The cause of the fume switch tripping is that the combustion chamber is NOT under negative pressure, i.e. gas is leaking into your house. The fume switch is doing its job by shutting the stove down.

Hop this helps.

nwaelder, I thought the same way about using a barometric damper. But, in Keystokers instuction manual it says that a barometric damper is not need on a direct vent system. With that said, I have 3 questions for you.
1- Is Keystoker mistaken in thier belief that a baro-damper isn't needed?
2- The vent pipe coming off the direct vent unit is 4"vent pipe. Can you get a good baro-damper in 4"?
3- If you were to install one, where is the best location on the vent pipe to instal it.

Thank You,
Shawn

I actually went online and googled some chimney caps and you can get draft proof ones. I might need to invest in something like that i guess.

1) Barometric Dampers or "Draft Governors" have been used on combustion systems for at leat 150 yrs, including stoves, railroad locomotives etc.
2) Yes I believ you can.
3) Location does not much matter i.e. between the flue from the stove and the chimney.

There are patents going back on this for 100 yrs. +++

Try to get it closer to the chimney than the stove.

The Keystoker design provides a positive pressure down stream of the stove since the power vent is mounted directly on the stove. The instructions call for sealing all joints in the living space with high temp silicon.

I believe adding a baro-damper downstream in the living space/basement would have disasterous results, in other words you would be introducing combustion gases into the basement or house.

Just my thoughts on the matter based on looking at the Keystoker 90 I own. :)
