Tjernlund HS-3C Canadian 8504002 Rev 2 09/97 - Manual (Page 4)

VENT HOOD LOCATION
NOTE: Termination of a Side Wall Vent System with a device other than the Tjernlund VH1 Series Vent Hood could affect system
performance and result in a possible safety hazard. Consult Vent Hood instructions for complete installation details.
If possible, locate the Vent Hood on a wall that does not face the direction of prevailing winds. This will diminish the possi-
bility of appliance interruption during periods of extreme winds.
