To determine if your model has a long vent system, refer
to the type code located on the serial number plate in the
inner door well. Example: An electric model would be DALV
– ELE – XXXXXXX-XXX. A gas model would be DALV – NAT –
XXXXXXX-XXX.
NOTE: For long vent systems, use of box/louvered hoods
will improve venting regardless of length.

Connect vent to exhaust hood
Vent must fit over the exhaust hood. Secure vent to exhaust
hood with 4" (102 mm) clamp. Run vent to dryer location using
straightest path possible. Avoid 90° turns. Use clamps to seal
all joints. Do not use duct tape, screws, or other fastening
devices that extend into interior of vent to secure vent,
because they can catch lint.
