NOTE:
If the unit has to be shorter than 86.5” cut the top of
the
bottom
part.
ATTACH FLEX, PIPE AND VENT TOGETHER:
Attach the flex to the pipe with 24” tie wrap. Attach the vent to the 6” pipe with the ½ in screws
provided. Avoid pushing against the flaps. From the outside, slide the pipe through the 6 ¼”
hole. Insert four 2 inch screws to secure vent to the outside wall. Make sure the vent is not
twisted from inserting the screws too tight and that the flaps are working properly. Apply
exterior caulking to act as a weather seal. From the inside, measure the distance between the
elbow and the flex.
Cut off the excess flex.
If this is not done, the
efficiency of the unit will
diminish drastically.
Now that the flex is tight, it can be attached to the elbow with the tie
wrap.
Flex should not be kinked in any
way.
