Chimneys
CI High-Resistance
Industrial Chimney
For over
30 years, Security Chimneys has been an innovator in the venting
field and a market leader in North America. Instrumental in the
company's growth has been the introduction of new products and
improvements to existing lines. This unrelenting quest for excellence
has now given rise to the Cl insulated chimney, a high-quality
product designed to deliver optimal performance. This new chimney
system ensures outstanding venting while minimizing condensation.
Field of Application
The Cl chimney
system is to be used with residential, commercial or industrial
heating appliances powered by either liquid or gas fuels. Its
sealing efficiency makes it suitable for negative or positive-pressure
appliances as well as for high-efficiency and high-condensation
appliances. It also has been tested by Warnock Hersey, according
to UL-103 HT (Ø 305 to 670mm/ 12to24 inches) for use with
masonry fireplaces (solid fuel appliances) (U.S.only).
Design
Security
Chimneys' Cl chimney is a stainless steel double-wall flue with
thermal insulation provided by a mineral-fibre liner between
its outer and inner walls. The inner wall of the Cl can be plasma
welded to ensure better corrosron resistance. It is also available
with mechanical locking seam.
Construction
The external
casing of the Cl chimney carries the structural load. The inner
lining is free floating and attached only to the male coupler
at the top, allowing it to expand and contract as flue-gas temperatures
change, therefore eliminating the need for special expansion
joints.
Composition
Selected
stainless steel:
The CI chimney system is available in various grades of stainless
steel selected for their resistance to high temperatures and
corrosion.
INNER
CASING AVAILABLE IN:
AISI 316 and 444
Calibre: 016, 024, 032 and 040
OUTER
CASING AVAILABLE IN:
AISI 316, 444, 434 and Galvalume
Calibre: 016, 018, 024
In Canada and the U.S. the 444 and 316 have proven remarkably
resistant to general corrosion and particularly pitting.
444 stainless steel: specially designed to be stable at high
temperatures and provide high-corrosion resistance. It is particularly
resistant to pitting corrosion in chlorine environments, because
of its molybdene alloy.
316 stainless steel: commonly used in chemical plants and the
ship-building industry because of its excellent resistance to
corrosion.
Technical data regarding the above steels are available from
our Engineering Department.
Insulation
The CI insulated
chimney is lined with the highest quality insulation, densely
packed to ensure low heat loss, maximum draft, minimal condensation
and a 50 mm (2 inches) close clearance to combustible materials.
The thickness of the insulation varies with the diameter; 127
to 254 mm (5 to 70 inches) = 25 mm (7 inch) of insulation.
305 to 610 mm (12 to 24 inches) = SOmm (2 inches) of insulation.
- For sizes greater
than 610 mm (24 inches) a 100 mm (4-inch) clearance is needed.
- For wood-burning
fireplaces and diameters of 305 mm (72 inches) or more, a 100
mm (4-inch) clearance from combustible materials is required.
