This summer I sided my house with cedar shake (shingle) siding of the red cedar variety. When I burned the old siding that I removed, also cedar shakes, it burned like kindling wood and made me realize that cedar is very flammable siding.

My vent is ICC Excel Pellet vent that goes out the wall to a Tee, then up three feet to an elbow then to the vent hood that looks like a dryer vent.

My concern is a spark making it's way outside and igniting the siding. Am I over thinking this possibility?

When I burned the old siding all it took to ignite was a match held to it for a second. That got me thinking about this whole issue.

Any opinions or ideas to prevent problems would be appreciated. And no, I don't need a spark bucket. :) ;)
 
If a single spark is all that would take to set your siding on fire, I would change it in favor of something a bit more flame retardent. (Yes, I know you just installed it).
 
Been burning pellets going on 9 years now, I've never seen a spark come out of my vent. I've seen sparks in the stove, but never outside. Your vent set-up is exactly like mine, minus one foot of vertical.

That's good to know. Thank you!
 
I have the same siding but different vent setup. I have Selkirk DT which has a nozzle looking termination that pushes the exhaust far away from the house. That is one of the benefits of the type of venting.

I have never seen any sparks come out of the venting. Even when the firebox is filled with burning fines when burning least quality pellets or I am burning down the hopper and pushing the fines into the auger to get burned up.

You could paint the wall with a clear fire retardant. This would make you sleep better. There are several products on the market designed for wood siding.

add a 1 ft section between the elbow and the cap, this should push you out to about 18 inches, should be more than enough open air to cool the exhaust sufficiently for the structure to be safe from the random spark. this is the recommended installation we put in our manual for this type of install with our stoves
