You can simplify connecting stovepipe by using
additional accessories such as telescoping pipes,
slip-connectors or clean-out tees. These accessories
ease the periodic inspection of your chimney, as well
as allow you to dismantle the stovepipe easily
(without moving the stove).
Install the stove as close as practical to the chimney,
while maintaining all proper clearances. Install
stovepipe that is as short and as straight as
possible. Horizontal runs of stovepipe must always
rise away from the stove at a minimum of 1/4" per
foot (21mm/m).
We do not recommend long runs of stovepipe to
increase
heat
dispersal
.
Longer
lengths
of
stovepipe, or more connecting elbows, than
necessary increase the chances of draft resistance
and the accumulation of creosote buildup.
In general, you do not need to install a stovepipe
damper with the Manchester. Some installations,
however, could benefit from a stovepipe damper,
such as a tall chimney which can create a higher
than normal draft. In such cases, a damper can help
regulate the draft. The Manchester requires a draft
between 0.06" and 0.1" WC. For drafts above 0.1"
WC, install a stovepipe damper. Check the draft at
stove installation time.
Remember, the NFPA recommends minimum
clearances for chimney connectors to combustibles
such as walls and ceilings. Once the stove is
installed at safe distances from these combustible
surfaces, it is also important to maintain these
connector clearances for the remainder of the
installation.

You can install your Manchester to a prefabricated
metal chimney, or to a masonry chimney.
This room heater must be connected to (1) a listed
Type HT (2100° F) chimney per UL 103 or ULC
S629, or (2) a code-approved masonry chimney with
a flue liner. The chimney size should not be less
than the flue collar, or more than three times greater
than the cross-sectional area of the flue collar.
We recommend installing a cleanout tee where
possible
to
simplify
chimney
cleaning
and
maintenance.
Connecting to a Prefabricated Metal Chimney
There are two ways to install a prefabricated metal
chimney:
An
interior
installation where the chimney
passes inside the residence through the ceiling
and roof.
An
exterior
installation where the chimney
passes through the wall behind the stove then
up the outside of the residence.
Whenever possible, choose an interior chimney. An
interior chimney heats up quickly and retains its
heat; thus promotes a better draft and discourages
the formation of creosote. An exterior chimney does
not benefit from the warmth of the building, so it
typically operates at lower flue temperatures than an
interior chimney and may experience increased
creosote accumulation.
When connecting the Manchester to a prefabricated
metal chimney, you must follow, precisely, the
manufacturer's installation instructions. Use only
Type HT (2100° F), prefabricated metal chimneys
listed per UL 103 or ULC S629 standards.
Ensure the size of the prefabricated chimn
ey’s flue
is appropriate for the Manchester. The Manchester
requires a 6" (152 mm) inside diameter flue for new
installations. A 6” diameter flue provides adequate
draft and performance. You can use an 8" (203 mm)
diameter existing flue with a reducer. An oversized
flue contributes to creosote accumulation. (In this
case, bigger is NOT better.)
When purchasing a prefabricated chimney to install
with your stove, Ensure you also purchase from the
same manufacturer the wall pass-through (or ceiling
support package), "T" section package, fire-stops
(when needed), insulation shield, roof flashing,
chimney cap, and any other required accessories.
Follow the manufacturer’s instructions when
installing the chimney and accessories. In addition,
ensure
you
maintain
all
manufacturers’
recommendations for the proper clearances to the
chimney.
Connection to a Masonry Chimney
Consider two primary elements when connecting
your stove to a masonry chimney: the chimney itself
and the thimble where the stovepipe connects to the
chimney.
Use only code approved masonry
chimneys containing a proper flue liner.
Before connecting to a masonry chimney, hire a
professional to examine the chimney for cracks,
loose mortar, and other signs of deterioration and
blockage. If the chimney needs repair, complete
them before installing and using your stove. Do not
install your stove until the chimney is safe for use.
