5 Hot air distribution and air return system
The Drolet furnace is designed and equipped with a hot air distribution plenum that may
receive 6 to 10, 6" (152 mm) diameter round ducts.
The installer is responsible of the performance of the distribution ducts and the air
return system. It will have a direct effect on the ability of the blower to distribute heat
efficiently throughout the house. The number, size and length of the ducts of the
distribution system and return air will vary depending on the configuration and
characteristics of each house.
N.B.: The furnace air jacket is not totally airtight. It is normal to detect some air leaks
at the jacket’s joints.
