The crimped end of the chimney con-
nector fits inside the furnace flue collar.
Install additional chimney connector and
elbow with the CRIMPED END TOWARD
THE FURNACE. This will allow any con-
densation in the flue to run back into the
furnace. Use 6" dia. (minimum 24 gauge)
black chimney connector.
Slope any horizontal pipe upward toward
the chimney at least 1/4 inch for each foot
of horizontal run.
You must have at least 18 inches of
clearance between any horizontal piping
and the ceiling. (See Fig. 3)
The chimney connector must not extend
into the chimney flue (See Fig. 6).
Seal each chimney connector pipe joint
with furnace cement. Also seal the pipe
at the chimney.
Use 3 sheet metal screws at each chim-
ney pipe joint to make the piping rigid.
The chimney connector may include a
section for a barometric draft regulator
between the furnace and the chimney
(Fig. 4, 5, 6, & 7). The barometric draft
regulator must be installed in the same
room (same pressure zone) as the fur-
nace.
Install the barometric draft regulator
strictly in accordance with the instruc-
tions that are provided with the baromet-
ric draft regulator.
A solid damper can be placed between
the barometric draft regulator and the
chimney. (Fig. 4, 5, 6, & 7)

Drill a hole in the chimney connector
within 18" of the flue collar below the
barometric draft regulator just large
enough for the tube of the manometer.
Build a fire after all chimney connec-
tions have been made.
Use a manometer to measure the draft
in the flue. (U.S. Stove Model DG-26)
Adjust the barometric draft regulator to
obtain a draft of 0.05" - 0.06" W.C.
under stable conditions.
