DRAFT
chimneys perform two functions.
1). As a means of exhausting smoke and flue gases
which are the result of fuel combustion.
2). The chimney provides “draft” which allows oxygen
to be continuously introduced into the appliance,
so that proper combustion is possible.
NOTE: The furnace does NOT create draft.
Draft
is a function of the chimney. A draft of 0.05 water column
0.1 Pa) is required for proper drafting to prevent back-
puffing, smoke spillage, and to maximize performance.
(Gauges to measure chimney draft are readily available
at furnace shops and are economical to purchase or
rent.) Do not exceed draft setting. Over firing and risk
of fire can occur.
As of April 1, 1987 all coal stoves must be installed
using a factory built chimney that meets the “Type HT”
requirement of uL 103 (when using a factory built
chimney).
ImPORTANT INSTALLATION POINTS
1. Size the chimney flue to the furnace pipe. (6” outlet
pipe = 6” chimney flue)
2. Avoid using elbows except as necessary.
Elbows reduce draft, no more than two elbows
should be used in any chimney run.
3. Make sure all horizontal runs of connector pipe have
a minimum outward rise of 1/4” per horizontal foot.
This allows any condensation or creosote buildup
to run back into the firebox.

cONNEcTOR MAKER’S INSTRucTIONS FOR
INSTALLATION AND uSE.
carefully follow chimney manufacturer’s
instructions. use only a listed chimney. If your chimney
starts at the ceiling (figures 13 & 14) you will need
enough 6” round black connector pipe to reach the ceil-
ing. The top of the chimney must be at least three (3)
feet above the roof and be at least two (2) feet higher
than any point of the roof within ten (10) feet (figure 13).
use only 6” diameter listed chimney uL 103 HT. chim-
ney made to this listing is High Temperature rated to
2100 degrees Fahrenheit. use chimney from only one
manufacturer. Never mix brands. carefully follow the
chimney manufacturer’s stated requirements and clear-
ances. use the chimney manufacturer’s attic guards,
roof supports, flashing and fire stops when passing
through a ceiling. use a listed thimble when passing
through a combustible wall. Do not use makeshift com-
promises during installation.
NEvER USE A SINgLE-
wALL CONNECTION PIPE AS A ChImNEY!
When using a pre-existing chimney, have it’s condi-
tion and installation inspected before using. Make sure
that the chimney meets all of the uL rating requirements
listed above. Be aware that not all manufactured chim-
ney is of the uL 103 HT type.
NOTE: It is recommended that you contact a
licensed heating and cooling contractor (consult
your local yellow pages) for chimney installation.
Manufactured chimney with the proper required uL
listing is available from most home centers, hardware
stores, and HVAc supply stores.
If you have access to the internet, you may wish
to view chimney manufacturers’ information on-line.

mASONRY ChImNEY
Before using an existing masonry chimney,
clean the chimney, inspect the flue liner and make
any repairs needed to be sure it is safe to use. Make
repairs before attaching the furnace. The connec-
tor furnace pipe and fittings you will need to con-
nect directly to a masonry chimney are shown in
figure 11 and 12.
If the connector furnace pipe must go through a
combustible wall before entering the masonry chimney,
consult a qualified mason or chimney dealer. The instal-
lation must conform to local building and fire codes and
latest edition of NFPA 211.
