We are installing a woodstove on the first floor of our 2 storey house. It's a
After pricing chimney pipe locally(wow!!) I found brand new triple wall pipe on
ebay. Unfortunately, it seems that the pipe is from a defunct manufacturer (my
google searches on "white metal products tristack chimney pipe" and subsets
don't yield any helpful sites, anyway).
I believe that I have everything I need, except:
a ceiling support box (for the first floor ceiling/second floor floor)
a radiation shield/fire stop for the roof/second floor ceiling
a flue adaptor from the single wall pipe from the stove, to the triple wall
pipe at the first floor ceiling.
After visiting Home depot, I see that the pipe and accessories that they sell
are not compatible with my pipe. I would be grateful for any suggestions before
I start modifying the home depot hardware to fit mine.
Check your local regulations, in many areas triple wall pipe is illegal to
use, because of a history of burn-through during chimney fires. This is
probably why the manufacturer went under.
Usually pipe, fitting, and accessories are all designed to fit the
manufacturer who made the product and for that one product only that was
approved by the authorities such as UL. Other manufacturer's pieces are
designed NOT to be mixed with a different manufacturer's chimney.
For your own safety, you need to install a currently approved product.
Yes it sounds like you have the right list. I can't answer
the question others brought up about the safety of your
pipe, but any approved pipe that is properly installed and
maintained will be safe. You may find that you need to have
some of the parts custom made for your pipe. The support
box and the roof pass through shouldn't be much of a
problem. The adapter from single wall to the triple wall
could be a problem. Check with any local wood stove
stores. If they don't have something you need to have a
custom adapter made and it needs to be made to keep any
liquids inside the pipe at the transition.
If you have never had a wood stove before, make sure that
you install the single wall pipe correctly so that any
liquid running down the pipe will stay inside. The old type
of installations where the next higher pipe section slips
OVER the lower section is upside down for modern
installations. That is, the next higher section needs to
slip INTO the lower section. This, of course, affects how
the single wall to triple wall adapter is made.
If you are not positive what you are doing, get a pro. Woodstoves are a
common cause of house fires. And be sure to check with your insurer. Many
insurers will not allow them and those that do certainly won't approve a
DIY installation. Building codes also are very precise about clearances and
They changed the size of the pipes a few years ago. I believe they went from
6 to 7 inches.
Uhh Dick, what you are saying about insurance isn't true in
all areas. Codes may be much more strict in areas where
heating with wood is uncommon. And, DIY is ok, one just
needs to pass the city/county building codes both for safety
and to be sure of insurance coverage. That's true of all
kinds of construction. I believe all of the major insurance
companies in my area cover wood stoves and adding a wood
stove doesn't significantly affect the cost of insurance.
The size of the stove pipe as well as clearances, afaik, are
part of the stove certification, so one needs only to follow
the stove manufactures installation instructions. Building
codes, at least where I am, are met if the item (stove,
stovepipe, etc.) certification is followed. Although there
are some general standards, clearances vary with products,
and can vary with options such as heat shields.
