Housing: The chimney sec-
tions can be installed in any
sequence, by length; however,
there are two important
considerations:

inside the thimble, join the
sections first before inserting
through the thimble.
2) The height of flashing and
chimney sections which pro-
ject above the roofline shall
not exceed 13'6" from ground
level for transporta tion pur-
poses. In (Figure 32). i t is
assumed the floor level of the
Manufactured Home is 30"
above the ground.
Step 5: The heignt of vertical
flue pipe supported oniy by
the fireplace must not exceed
30 feet. Flue heighls above 30
feet must be supported by a
Model 6 3 4 unitized stabilizer
installed at 30 foot intervals.

Note: The Model 8-S4 unitized
stabilizer adds 2% inches net
effective height to the total
chimney system.
Figure 32
Install the model 8-54 stabili-
zer by fitting inner section
down into respective section
of preceding flue pipe and
locking outer stabilizer sec-
tion into place over the outer
flue pipe. Position for proper
clearance through framed
opening and nail straps
securely (under tension, in
"shear") into place on fram-
ing. Use 8d nails. Attach
successive lengths of flue
pipe directly to stabilizer
using same technique as
described in Step 3.
Note: Do not apply excessive
pressure to any subsequent
chimney sections following
the stabilizer when installing.
Insure each subsequent chim-
ney section is securely
attached, however, by testing
as noted i n Step
4.
Step 6: Select proper Superior
roof flashing, depending on
the pitch of roof. Use chart
below for selection:

Next, slide roof flashing over
extended chimney section
that previously had been
instalied above the roof open-
ing in Step 4. Slide flashing
all the way down until the

Step 7: Secure flashing by
nailing along perimeter into
roof using 8d nails. If shingled
roof, slide upper end and
sides o f flashing under
shingles (trim if necessary)
(Figure 34% seal the top and
both sides of the flashing to
the roof with roof caulking.
Cover nail heads with roof
caulking.
