CHIMNEY AND FITTING JOINT ASSEMBLY
All components have a male and female end. The installation orientation
is indicated on the labeling of each chimney section with an arrow. The
arrow indicates the direction of the flow. Clean all inner and outer surfaces
of the male and female ends with an appropriate organic solvent, such
as acetone, Mek, or other commercial degreaser.
1. Apply a bead of S-650 sealant about 1/8” thick around the male end
of chimney and for Grease duct application, add a bead of S-2000
sealant at the edge of the female chimney (see figure 2). See table
5 for approved sealants.
2. Insert the female end, of another section of chimney, over male end
with sealant (see figure 3).
3. Insert the assembly band (see figure 4) around the joint of the two
sections assembled in step 2. A small bead of S-650 can be applied
on the inner groove of the band prior to installation for better leak
tightness.
4. Using a phillips screwdriver, connect the two ends of the band as
shown in figure 5.
5. Where the chimney is installed outside, an exterior sealant S-375
must be applied at the upper joint of the band and the outer casing,
see figure 5.

CAUTIONS
A. DO NOT ALLOW SCREWS TO PENETRATE THE INNER FLUE.
THIS CAN CAUSE CORROSION, GAS LEAKAGE OR EXPANSION
FAILURE.
B. NEVER USE SCREWS THROUGH THE OUTER CASING OF AN
ADJUSTABLE LENGTH OR EXPANSION JOINT.
C. OBSERVE ADEQUATE SAFETY MEASURES WHEN USING A
DEGREASER.
