ConstructionFLAMEBAR BW11 grease duct is constructed from 20 gage galvanized sheet steel in flanged lengthsup to 49” x 49” cross section. The duct is then degreased and factory fire sprayed with FLAMEBARBW11 which is a specially formulated water based compound which contains selected mineral fi ltersin a lower permeabil ity elastomeric binder to a thickness of approximately 0.04” to give a finishedproduct. The ductwork is produced in flanged sections, each approximately 59” long, and isassembled on site using FLAMEBAR gaskets and sealants. The ductwork is then wrapped withFyreWrap® max 2.0 duct insulation, consist ing of two layers applied directly to the duct surface. TheFyreWrap® max 2.0 may be installed at zero clearance to combustibles at all locations on the wrap.

All the above components are necessary to achieve ASTM E-2336 l ist ing.

The fir st layer of insulation can be installed with transverse (per imeter) joints butted and minimum 3”longitudinal over laps.

All over laps for the second or outer layer are required to be a minimum of 3”. For the second layer,transverse (per imeter) over laps of adjacent blankets may be installed using one of the following threemethods as shown in Figure 1.

UL 1978 Section 11.4a requires that the thermal insulationremain in its intended position. The Unifrax FyreWrap® Max 2.0thermal insulation is mechanically attached to the FiresprayBW11 Grease Duct Assembly, using standard copper-coatedsteel insulation pins and standard 2.5 inch square speed-clipwashers. The Unifrax FyreWrap® Max 2.0 thermal insulationremained in place during all tests. Therefore, the requirementsof UL 1978 Section 11.4a are met by the Firespray BW11 GreaseDuct Assembly with the applicable layer(s) Unifrax thermalinsulation applied.

UL 1978 Section 11.4b requires that the thermal conductivityof the thermal insulation not be increased reducing itseffectiveness, UL 1978 does not provide a method fordetermining the thermal conductivity or when the thermalconductivity tests are to be conducted or where the samplesare to be taken. Therefore, an analytical assessment ofUnifrax FyreWrap® Max 2.0 thermal insulation is being used.According to published information. “FireWrap® Max 2.0incorporates Insulfrax® Thermal Insulation as its core material.”Insulfrax calcium-magnesium-silicate fiber is recommendedfor continuous use at temperatures up to 1000°C (1832°F).

Sections d and e relate to porcelain-coated ducts only.

Assumption 1

16 gage black steel with welded seams and jointshas a UL listing.

Incorrect: UL 1978 can only test for “porcelain coated” or stainlesssteel ducts as required by Clause 7.3.

Assumption 2

NFPA 96 requires black steel with welded seamsand joints.

Incorrect: Clause 1.5 equivalency states “nothing in this standard isintended to prevent the use of systems, methods or devices of equivalentor superior, quality, strength, fire resistance, effectiveness, durability andsafety over those prescribed by this standard.

Technical documentation shall be submitted to the authority havingjurisdiction to demonstrate equivalency. The system, method or deviceshall be approved for the intended purpose for the authority havingjurisdiction.”

Assumption 3

It is widely considered that NFPA 96 is a test standard.

Incorrect: lt defines compliance with NFPA 96 as Chapter 4Clause 4.3.1.2.

Assumption 4

It is assumed that all grease duct testing should beto UL 1978.

Incorrect: As of January 2009, Underwriters Laboratories, IntertekServices and the International Code Council Evaluation Services (ICC-ES)are jointly abandoning all listings or evaluations that are based on SBCC1and BOCA acceptance criteria, both of which use the internal fire testportion of UL 1978, which addresses reduced clearances for field appliedflexible wrap systems. Once these are abandoned, the only listing forflexible wraps applied to grease ducting will be ASTM E-2336-04.

Assumption 5

There are no other grease duct fire tests.

Incorrect: Firespray have installed literally thousands of grease ductsystems around the world including the USA for more than 20 years andhave a listing for this under IS0 6944, which in some aspects is a moreonerous test than ASTM E-2336. One of the anomalies in E-2336 is thatthe test for a fire inside the duct is 4 hours at 500°F and then 30 minutesat full temperature at approximately 2000°F. If the partition throughwhich the duct passes is a 2 hour separating element, why is the duct(fire inside) only tested for 30 minutes. We have carried out the same testunder IS0 6944 for 2 hours (fire inside and outside) at temperatures inexcess of 2000°F
