High-Temperature Factory-Built Chimneys

APPLICATIONS
The Secure Temp S2100 has been designed to widely
exceed existing safety standards while offering the best
available chimney system. It has been designed for use with
wood, gas, oil, or coal-burning appliances. The Secure Temp
S2100 high-temperature chimney is certied by Intertek
Testing Services (Warnock Hersey) to ULC S629 standards
for diameters of 6, 7 and 8 inches.
A TRADITION OF EXCELLENCE
For over 50 years, Security Chimneys has been an innovator
in the venting eld and a market leader in North America.
Instrumental in the company’s growth has been an ongoing
focus on product improvement and the introduction of new,
innovative products. This drive for excellence has given rise
to the Secure Temp S2100, one of the most popular lines
of venting products in North America. These high-quality
products ensure that end-users benet from maximum
safety and proven corrosion protection.
INNOVATIVE COMPOSITION AND EASE OF INSTALLATION
The use of stainless steel, selected for its resistance to high
temperatures and corrosion, lends outstanding durability to
the Secure Temp S2100 high-temperature chimneys. Secure
Temp S2100 has a temperature rating of 650°C (1200°F);
max. continuous, 760°C (1400°F) brief forced red; and
1150°C (2100°F) 3 x 30 minutes, tested.
All chimneys feature 2 inches (S2100) of superior-quality,
high-density Secura Plus insulation. This exclusive insulation
keeps the temperature of the outer casing relatively low,
keeping safety features as simple as possible. The S2100,
with 2 inches of insulation, is well-suited for outside
installations in areas where very cold temperatures occur.
All Secure Temp S2100 high-temperature chimneys,
regardless of diameter, can be installed as close as 2 inches
from combustible materials.
The S2100 also features fast and easy Twist-Lock assembly.
Lengths and universal ttings t together and lock into place
by twisting one-eighth of a turn. No other part is needed to
ensure the chimney’s structural stability, keeping installation
time to a minimum.

Offset and rise calculation
The following steps will help determine
the lengths required for an installation:
1. Determine the offset required in view
of the obstacles that must be avoided.
2. Refer to the “Offset/Rise Chart" to
determine the elbows required as well as
the insulated lengths needed.
3. Check the corresponding offset height
dimensions.

Installation
Assembly always requires the male coupler to be
positioned upwards. Size the chimney in accordance
with the appliance instruction manual. Map out the
chimney path closest to the heating unit. Prior to
installation, consult the detailed installation manual
included with the support components.
Any replaces and controlled combustion units
can be connected to the Secure Temp S2100,
since it has been certied, independently, to ULC
S629M standards.
SAFETY
Security Chimneys Secure Temp S2100 chimneys
can be installed as close as 2 inches to combustible
materials, regardless of the diameter to be used.
Radiation shields and appropriate supports must be
used to maintain a safe clearance as the chimney
passes through oors and combustible partitions.

Secure Temp®ASHT
Secure Temp
APPLICATIONS
The Secure Temp ASHT is one of the most extensively
used factory-built venting systems in North America. It has
been specially developed for use with oil and gas burning
heating appliances and certied wood-burning replaces.
The Secure Temp ASHT high-temperature chimney is
certied by Intertek Testing (Warnock Hersey) to ULC S604
standards and ULC S610 (on wood-burning replaces) for
all diameters of 5, 6, 7, 8 and 10 inches.
CERTIFICATION
The Secure Temp ASHT high-temperature chimney is certied
by Intertek Testing (Warnock Hersey) to:
• ULC S604 standards for all diameters of 5, 6, 7, 8, and
10 inches.
• ULC S610 (on wood-burning replaces) for all diameters of
5, 6, 7, 8 and 10 inches.
• ULC S629 for wood stove applications in diameters of 6, 7,
and 8 inches.
INSTALLATION
Assembly always requires the male coupler to be positioned
upwards. Size the chimney in accordance with the appliance
instruction manual. Map out the chimney path closest to the
heating unit.
For wood stove applications, a third pipe (premium shield) is
required for inside installation where the chimney is enclosed
between two oors (see premium shield accessories section).
Prior to installation, consult the detailed installation manual
included with the support components.
SAFETY
Security Chimneys's Secure Temp ASHT chimneys can
be installed as close as 2 inches to combustible materials,
regardless of the diameter to be used. Radiation shields
and appropriate supports must be used to maintain a
safe clearance as the chimney passes through oors and
combustible partitions.
Some radiation shields in the Secure Temp ASHT line
have been designed specically for use with wood-
burning replaces. For the use of Secure Temp ASHT with
manufactured wood replaces, refer to the instruction of
these products.

This complementary support is usually attached to a roof structure. It is designed to
support the chimney:
• from the roof, adjusting to any roof pitch
• above an offset
• when the chimney height exceeds the loadbearing capacity of the primary support.
Two adjustable plates screwed to the structure adapt to the pitch of the roof. A
tightening collar is attached and locks around the chimney. It is secured by self-
tapping screws. (Refer to the chart on pg. 4 or 8 for loadbearing capacity.)
