Dear ,

November 19, 2012

In an effort to make our numbering system more consistent, we will be updating our Order Numbers to more clearly reflect what product you are ordering.

Current (old)

Order Number


Order Number

Numbering Method



5" Diameter DuraTech (DT) Firestop Radiation Shield (FRS)



7" Diameter DVL 46" (46) Telescoping Length (TL)

This method of numbering will make it easy to understand exactly what the part is. We realize when there is a change in Order Numbers, there will be a learning curve so we have created a cross reference guide to provide an easy way to compare the Current (old) Order Number with the New Order Number.
Product lines that will see New Order Numbers include: DuraTech, DuraPlus, DuraPlus HTC, DVL, DuraBlack, PelletVent, Pelletvent Multi-Fuel, DuraLiner, and Ventinox. Product lines that will maintain their current Order Numbers include: PelletVent Pro, DuraFlex, DirectVent Pro, Type B Gas Vent, and FasNSeal. UPC Codes will not be effected by this change.
In May of 2013 we will be going live with our new SAP Enterprise System, and all Stock Numbers will be replaced by a 9-digit number.

We have set up a change schedule (below) to allow customers a chance to learn the New Order Numbers. 

November, 2012:
Notification of change and cross reference provided to customers. Click here to view cross reference guide.

Effective January 1, 2013:
New Order Numbers will be in place. Customers will be able to order utilizing the Current (old) Order Number or the New Order Number. Please take the time to learn the New Order Numbers prior to May 1st, since all Current (old) Order Numbers will be obsolete at that time. Cross reference sheets will continue to be available.

Janurary, 2013:
New DuraVent Catalog will be published with New Order Numbers and Stock Numbers. A cross reference will be included in the 2013 catalog. A New pricebook will be published at this time and will list all New Numbers (Order and Stock/SAP) with a cross reference to the all Old Numbers (Order and Stock).

Effective May 1, 2013:
Current (old) Order Numbers will be obsolete. Customers will order utilizing the New Order Numbers or the 9-digit numbers. Cross reference sheets will continue to be available.
