Viking Achieves Enhanced UL Listing for Its BlazeMaster® CPVC Piping System

Hastings, MI, USA - Viking Corporation, a global leader in fire protection and life safety systems, has received a new, expanded UL Listing for its BlazeMaster® line of CPVC piping products which allows for exposed piping installations in basements with composite wood joists, commonly called TJI® joists.

These enhanced Listings can provide significant cost savings for residential fire sprinkler systems. Previously, when sprinklers were installed in an unfinished basement with composite wood joists, a layer of drywall was required to cover the CPVC piping network. Alternatively, metallic pipe could be used in these applications. With this new UL Listing, provided certain conditions are met, Viking's CPVC piping system can be installed exposed, without the need for additional drywall protection. The result is a lower total installed cost for residential sprinkler systems.

These new Listings also allow for exposed CPVC riser installations in NFPA 13R and 13D residential systems. Viking has updated its "Installation and Design Manual" for BlazeMaster® CPVC systems with two special addendums that outline the specific construction and installation requirements that must be met, including requirements for ceiling heights, joist depths, sprinkler K factors, and temperature ratings. The updated installation instructions can be found at Additionally, Viking provides convenient access to CPVC product information on a smart phone or tablet via its mobile web site,
