3.4 Connection to Chimney or Vent

Follow the recommendations by the vent or stack

manufacturer. For optimal performance, the distances in

Fig. 6 should be observed.

3.5 Connection to Flexible Duct

Flexible duct (FLF) is used to reduce the effects of

pulsating appliances on the fan and duct system. If used,

the FLF should be connected between the fan inlet/ outlet

and the main vent or stack as shown in Fig. 7. This will

decrease vibration in the system and prevent deflection of

the fan housing.
