FIG. 8 – GUYING FOR SINGLE SECTION
FIG. 9 – CHIMNEY GUYING REQUIREMENTS
Cables should be spaced at or near 120º intervals (3 cables)
or 90º (4 cables). Rigid bracing requires two (2) braces spaced
between 60º and 150º apart. Maximum spacing between the
fixed support and the guy ring is 5 feet when rigid bracing is used
(See
FIG. 10
).
PIPE LENGTHS (9, 18, 30, 42)
Model PIC/IPIC pipe is available in 4 standard lengths: 9” (229),
18” (457), 30” (762) and 42” (1067). Pipe sections are joined,
using appropriate sealant, to make up desired length of run.
These sections may be modified by use of nipples or couplings
to accept auxiliary equipment such as temperature probes or
smoke monitors. Consult factory or your local representative to
obtain information regarding such modifications.
DRAIN SECTION (DS)
A drain section is a special variation of an 18” (457) pipe length
with provision to drain rain or condensate from the chimney. The
pipe flue is equipped with an annular catch ring and a 1” (25)
NPT nipple extending through the casing for attachment of drain
piping. The drain piping should include a water leg of a height
at least equal to the maximum expected operating pressure at
the appliance outlet to avoid allowing flue gases to vent through
the drain. Drain section should be installed indoors to prevent
freezing (See
FIG. 11
).
