5.8.2 Exhaust Vent Installation (CS/NX Model)
The Nortec GS (CS/NX model) humidier must be installed as a Category IV fan-assisted gas appliance.
In addition to the specic requirements described in "Installation as a Category IV Appliance" on page 48, refer
to the general requirements – "General Requirements" on page 43.
All vent installations must be in accordance with national and the local regulations.
The exhaust outlet on the unit has a female connection (metric). Each unit is supplied with a metric to
imperial adaptor (with internal gaskets) to accomodate imperial vent sizes.
To connect the exhaust vent, rst insert the adaptor into the exhaust outlet and secure it to the top panel
with four sheetmetal screws (supplied) – refer to Figure 22. Then slide the exhaust vent into the adaptor
until it bottoms out, and secure it with the clamp built into the adaptor. A sealant is not required.
Make sure that the exhaust vent is supported by hangers or pipe straps so that there is no load on the
humidier.
