Instructions Valve installation
Fix the bayonet socket that will hold the valve to
the ceiling. If it is a gypsum ceiling, we recom-
mend putting a wooden plate on the back for
the screws to bite into. If the duct needs to pass
through insulation, we recommend measuring
the insulation section and installing a duct sec-
tion along a suitable length of the bayonet socket
(VGU or VGM). Use an NPU connection nipple to
connect the VGM and the duct section.
