3. Assemble the Wall Support - follow instructions on page 20.
4. Fasten the required chimney length to the Tee side entrance. The
horizontal chimney section must extend through the finished interior
wall by at least 4 inches. In some cases you may wish to use an
adjustable length in combination with a short length for this purpose.
Attach the flue extension (EX) found in the EWRS box, to the end of
the horizontal chimney length using the 3 metal screws provided.
5. Fasten a chimney length to the top of the Tee.
6. The wall support should be installed on the first vertical chimney
section above the Tee. Tighten the universal band locking bolt just
enough to hold the wall support in place.
7. Install this assembly through the hole in the radiation shield.
8. Fasten the Wall Support brackets to the outside wall in a convenient
location directly above the hole. Use four #10 x 3" or larger screws.
Insure that the screws are fastened into a structural member and not
only to the wall sheeting. If the stud locations do not line up properly
you may wish to use a wall channel - see instructions page 24. The
Wall Support brackets are slotted to allow them to adjust in and out.
Adjust the brackets so that the chimney is a minimum of 2" from the
wall and parallel with it. Tighten the Wall Support collar around the
chimney, then secure it using 3 metal screws.
9. Stack the next chimney length in place. Align the vertical seams, this
will also align the screw holes. Fasten the lengths together using 3
metal screws. Continue installing lengths until you reach the roof or
until the required overall height is achieved. Many installers prefer to
screw two or three vertical lengths together in advance because it is
easier to screw the chimney sections together in the open than when
they are close to a wall.
10. If the chimney is installed in a combustible chase then a roof radiation
shield (ERRS) must be installed immediately below the flashing or
chase top and a ventilated flashing (EVF) must be installed. See
drawing on page 22.
11. If the chimney passes through the roof, cut a hole large enough to
provide 2" clearance between the chimney and the roof. Install a
radiation shield (ERS) from the bottom to seal the opening. Continue
installing lengths as required.
12. Install another Wall Support at 8' intervals. The Wall Support should
be adjusted to ensure the chimney is vertical and at 2" (or more)
clearance to combustibles.
