Every document for the ChesGuard CG-GD1 in one place. The manuals are the full printed instructions that ship in the box, reproduced exactly, and the certificate is the original issued by Intertek. Building owners and managing agents in New York City are required to keep proof of compliance and a record of the manufacturer's stated useful life, so download and file the certificate along with your installation dates.
The manuals are large files. English is about 17 MB and Spanish is about 20 MB. Both open in a new tab.
