Continue Installing Pipe to Complete Run
Continue attaching pipe sections to complete system
to next level always being careful that both the inner
and outer pipe sections are firmly snap-locked in place
before proceeding to next pipe section.
Install Remainder of Chimney Sections
Since you have preplanned the height of the termination
according to the Ten Foot Rule, continue to install pipe
to the predetermined height. Install chimney sections
until ONE SECTION (both pipes) extend through the
roof hole.
Installing Top Housing or Termination
The minimum height for the straight-up mobile home
chimney is 10'6" (3.2 m) measured from the fireplace
hearth to the flue exit at the Chimney Top. (Fig. 17)

Removal of Chimney Sections for
Road Clearance
To comply with over-the-road height limitations, the
SKMH8-PA pipe adapter may be required for easy re-
moval of the chimney section and chimney top. Refer to
instructions provided with the SKMH8-PA.
Install Mobile Home Chimney Top
The standard Vermont Castings Group RLTSK8 round
top can be used to terminate the chimney in a mobile
home installation.
It is recommended that guy wires be used to support
any pipe and chimney assembly which extends higher
than 6 feet above the roof line.
Slide the flashing (8-6-12-MH) over exposed outer pipe
and exposed section of the Radiant Shield/Firestop.
Mark the area it covers on the roof.
NOTE: For flat roof applications, trimming of the 8-6-12-
MH is necessary. Laying the flashing on a flat surface,
measure 1 inch down on the cone at the high side.
Starting at this point, trim outward until you intersect
the edge of the cone. Slightly lift the flashing and coat
the roof area inside the markings with a good quality
roof cement (not provided). Push the flashing down and
press it firmly into the roof cement. Securely fasten the
flashing to the roof using sheet metal screws. Coat the
screw heads with the roof cement.
Insert the drawband tab through a slot in the end,
tighten until the drawband is snug against the outer pipe
and flashing, then bend tab back over slot to secure
drawband. (Fig. 18) Apply caulking around top of draw-
