haier Gas & Electric Dryer RDE/RDG 350AW - Manual (Page 9)

maintain a minimum of 12 inches (30.5cm) clearance between the vent hood
and the ground or any other obstruction. The vent flap should be able to move
freely, although vertical orientation of the exhaust system is acceptable. Certain
extenuating circumstances could affect the performance of the dryer:
1. Only rigid metal duct work should be used.
2. Venting vertically through a roof may expose the exhaust system to down
drafts causing an increase in vent restriction.
3. Running the exhaust system through an uninsulatedarea may cause
condensation and faster accumulation of lint.
4. Compression of crimping of the exhaust system will cause an increase in
vent restriction.
The exhaust system should be inspected and cleaned a minimum of every 12
months with normal usage. The more the dryer is used the more often you
should check the exhaust system and vent hood for proper operation.
