3.3.2 Duct or pipe mounting
If installed in a ventilation duct or pipe, it is recommended to use the “Duct flange kit” as
shown in the illustration below. To get better gas coverage inside the duct it is recommended
to use the PGE11 with the extended gas sensing section as shown below.
The mounting is done by fixing the flange (A) to the installation. Attach the gasket and the
mounting bracket (B). The PGE11 (C) is slided onto the mounting bracket and fixed with two
bolts and the support bracket (D). The Duct flange kit is supplied with a nozzle (E) to allow gas
testing to be performed without removing the detector from the duct flange.
