ok...new issue with new install of Harman Magnum Stoker.

The install was successful without the need to install a barometric damper. When the stove was burning, both test spots pulled .05 draft.

but, i let the stove go out (it got warm) and the other day it rained. we only got 1/2" of rain, but quite a bit came down the chimney. i had the installer return today to check chimney cap...he claims it is the best he's seen and was recommended for the stove pipe. he claims that perhaps because of not enough or no draft that the rain went it. there was no other evidence of water ANYWHERE but on the stove...it ran down the stove pipe.

any suggestions how to stop the rain?

There will be rain all year long when it is not heating season!! There should not be rain coming down the chimney in any quantity. There is something wrong. Did the water travel down the outside of the pipe or inside??

Unless the rain you had was driven by a lot of wind, any rain cap should have prevented rain getting into the pipe. If there is water running down the outside of the pipe, then the pipe is not sealed correctly at the top or at joints.

If the rain was accompanied by a lot of wind, then wait till you have a more normal rain and see what happens. But if there wasn't a lot of wind, then get a different rain cap or a different chimney product or installer. Something is not right

i agree with you about it raining year around! OUCH!

the rain was on the exterior of the stove pipe. i didn't think to look to see if there was water on the inside of the pipe albeit i doubt if i could have discerned that due to the enclosure of the magnum stoker.

my guess...the rain somehow got inside the pipe, then at one or more of the junctions that take place traversing to the interior stove pipe, the rain worked though a joint.

clear as mud?

in retrospect, i gotta admit, the rain cap that is on this new chimney looks like a very good cap with much more enclosure than i ever had on my previous wood burning stove cap on my last home.

i guess i'll wait to see what it does the next time it rains, but i fear it wasn't a driving rain this last time it rained.

Is this pipe a liner that goes inside a conventional brick or block chimney?? Or is is a stand alone metal chimney?

If it is a liner in a block chimney, then the liner should have a seal or cap where it exits the block chimney.

It's a stand alone metal chimney.

I fly for JetBlue Airways, I fly the A320. I'm based in JFK, live in Michigan, about an hour drive from DTW. I commute ~500 miles to work on other airlines. !!

Been flying for about 30 years now. Can't wait to retire. If I can afford to ....


With your stand alone metal chimney, There definitely is a problem, I'm thinking that the flashing on the roof where the chimney goes through the roofing and shingles. Or maybe the sealing ring around the outside of the chimney where it goes through the flashing ring [ that attaches to the roofing].

The water that is on the outside of of the chimney was clean, right? No soot stains from inside the chimney right??

It is something simple, just have to find it.

I did a metal chimney in my garage with a Williamson hot air furnace. The rain would run down the outside of the pipe into the garage. There should be a storm collar around the pipe after it exits the roof and it MUST be sealed w/hi temp silicone.
