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.
