DURAVENT single wall Model DCL and double wall models DAS1, DIS1, DIS2 and DIS4

venting systems are listed by Underwriters Laboratories, Inc. (UL) in the following

product categories and in the diameters indicated:

Model D A S - P R O (DAS1 - Double wall, 1" air insulation)

Building Heating Appliance Chimney

1400° Fahrenheit Chimney

Models D I S - PRO (Double wall, DIS1, DIS2 or DIS4) where the number

equals ceramic fiber insulation thickness

Building Heating Appliance Chimney(Type HT)

APPLICATION

UL 103 Building Heating Appliance Chimney

Listing:

Under this category, models DAS-PRO and D I S -PRO have been determined suitable

for venting flue gases at temperatures not exceeding 538°C (1000°F) under

continuous operating conditions from gas, liquid, oil or solid fuel fired appliances. Also

complies with operation (less than one hour) at temperatures not exceeding 740°C

(1400°F) and brief operation (maximum 10 minutes) at temperatures not exceeding

906°C (1700°F). Building Heating Appliance Chimneys are suitable for use with

Building Heating Appliances and Low Heat Appliances as described in the Chimney

Selection Chart of National Fire Protection Association (NFPA) Standard NO. 211.

Building Heating Appliance Chimney (Type HT) Listing 5" to 24" DIS-PRO

ONLY

Under this category (UL 103HT), the 5" through 24" ID DIS-PRO Models have qualified

for UL's additional, optional "Type HT" rating (for Building Heating Appliance

Chimneys) which indicates they have been evaluated and found suitable for exposure

to 2100°F flue gases for a 10 minute duration at a specific clearance for each

Model and diameter. Many local, state and regional code authorities require a

"Type HT" rating for chimneys for certain appliance venting applications; especially

solid fuel.

Building Heating Appliance Chimneys are suitable for use with Building Heating

Appliances and other Low Heat Appliances as described in the Chimney Selection

Chart of National Fire Protection Association (NFPA) Standard No. 211.

1400°F Chimney Listing - Under this category (UL 2561,ULC-C959), Model D A S -

PRO and DISX-PRO have been determined suitable for venting flue gases continuously

at a temperature not exceeding 1400°F, and a 10 minute intermittent service at

temperatures not exceeding 1800°F. As such, Model DAS-PRO and D I S -PRO

Models are suitable for use with ovens and furnaces as described in the Chimney

Selection Chart of NFPA No. 211, in addition to other Applications.

Engine Exhaust

Based upon the above referenced UL Listings and supplemental, UL confirmed

pressure testing, Model D A S -PRO and D I S -PRO are also suitable for use as

complete exhaust systems for diesel engine and gas turbines. When Model DAS-PRO

and DIS-PRO is used as an engine or turbine exhaust it is intended to be installed in

accordance with NFPA 37 "Stationary Combustion Engines and Gas Turbines". This

code states, "When such (flue gas) temperatures do not exceed 1000°F (538°C)

except for infrequent, brief periods, the engines shall be classified as low heat

appliances". For continuous operation over 1000°F and not exceeding 1400°F the

exhaust system should be installed as a 1400°F Chimney.

Models D I S -PRO may be used to meet various needs, such as:

Models DAS-PRO and D I S -PRO exhaust systems are intended for use in connecting

5"- 36" ID

the heating appliance, engine, or turbine to the outdoors, while operating under

positive forced draft, negative induced draft or neutral gravity flow internal

5"- 36" ID

pressure conditions. Models DAS-PRO and D I S -PRO (all insulation thicknesses)

may be intermixed in the same chimney system, assuming the proper associated

airspace clearances-to-combustibles are maintained.

ADDITIONAL

5"- 36" ID

APPLICATIONS

5"- 36" ID

Models D CL, DAS1 and D I S -PRO are also suitable for negative, neutral or positive

pressure pre- fabricated piping systems intended for use in a variety of

5"- 36" ID

applications including but not limited to the following:

Particle Conveying, Dryer Vents and Ventilation Ducts.

SUITABLE FOR POSITIVE PRESSURE VENTING APPLICATIONS WITH MAXIMUM 60"

WATER COLUMN INTERNAL STATIC PRESSURE AT 1000 DEGREES F.

MULTI-ENGINE

EXHAUSTS

A common exhaust system for multiple engine or turbine installations is generally not

recommended. Check with your engine or turbine manufacturer prior to common

exhaust system design. Exhaust gas from operating units tends to flow to non-

operating units where condensation may form. Water in engine or turbines at start-up

may cause damage. In general, a separate exhaust system should be provided for

each engine or turbine.

a) Reduce outer pipe surface temperature.

b) Reduce building heat gain by retaining energy inside the vent.

c) Increase the efficiency of energy recovery systems by reducing exhaust

gas temperature losses.

d) Increase chimney or exhaust system draft loss performance due to

reduced exhaust gas temperature drop.

e) Reduce building noise levels caused by high speed or pulsating exhaust

induced noise. NOTE: Specific tests have not been conducted to measure

acoustic performance.
