Installation Guide
Besides following the appliance instructions for connectors, other
rules for solid fuel appliance connectors are:
1. Never enclose single wall pipe, even at 18 inches clearance.
2. Never run it through ceilings or floors, or windows.
3. Don’t use single wall pipe outdoors.
4. Always secure all single wall joints with at least 3 screws.
5. Obtain proper attachment parts for the appliance end for the
entry to the chimney. See the MetalBest Chimney Systems
catalog for 6", 7", and 8" size Dripless Smoke Pipe Adapter
(DSAC) or (DSA).
6. Locate or support the connector to avoid contact or damage.
7. Caps or plugs for single wall tees should be secured against
falling out and designed so they can’t leak creosote or rain.
8. Heavy weight pipe lasts longer. Use 24 gauge if possible.
9. Porcelain enamel is the best high temperature protective finish
(but requires careful handling and may be difficult to assemble
securely except in a vertical position).
10. Galvanized steel pipe is no better than plain black or painted
steel because the galvanized zinc coating is ineffective once it
has been overheated.
11. Operating the stove, heater or fireplace when the connector
is red hot is very dangerous. This indicates over-firing or a chimney
fire. Stop firing, close the dampers, let things cool off, and keep
watching for problems on nearby walls and furnishings.
12. The slope of the horizontal portion of a connector of 1/4 inch
per foot is sometimes a building code requirement. This slope
will have little effect on safety, appliance operation or creosote
drips. If the connector is vertical, it should be installed with the
crimped end down. If it can be sloped between the stove and
chimney, use 45 degree one piece leakproof elbows (such as
the corrugated type), and try to maintain sufficient slope so that
any condensate liquid runs back toward the appliance. To keep
liquids from coming out connector joints, the small (or crimped)
end should always be down - or toward the stove or fireplace.
13. Passing a bare smoke pipe or connector of a wood burning
appliance through a combustible stud wall is not recommended,
as the entire inside of the wall must be cut away to get 18 inch
clearance (usually at least a 40 inch circle). Wherever possible,
locate the chimney to avoid penetrating a wall with a single wall
connector.
NOTE:
The purpose of the diagonal arrows is to show that the 18
inch clearance DOES NOT APPLY to the vertical connector
entering a Finish Support. This support is actually tested
with a bare vertical connector and must pass the UL tests
with very hot gases entering the bare single wall pipe.
