Important: Before installing the ZFR1811 Router in plenum
applications, verify acceptance of exposed plastic materials in plenum areas with
the local building authority. Building codes for plenum requirements vary by
location. Some local building authorities accept compliance to UL 1995, Heating and
Cooling Equipment, whereas others use different acceptance criteria.
