1. Unscrew and remove the existing roof vent.
2. Remove any caulking compound around the roof
or wall opening. A clean surface offers a better
seal. Consult your RV owner’s manual for cleaning
recommendations.
3. Seal any screw holes and seams where the roof
gasket will be located, using a good grade of
all-weather roof sealant.
3.2 Assessing the Trim Garnish
1. Determine the length, width, and thickness or depth
of the roof or wall opening where the new fan vent
will be installed.
2. Confirm you have the correct trim garnish for the
depth of the roof or wall opening. See “Trim Garnish
Dimensions” on page6.

(CC) to the correct height, if necessary.

around all four sides from the top edge. Score the
marked lines.
b. Cut from the top edge of the corners at a 45
degree angle down to the score line, then break
the excess plastic away from the trim garnish (CC).
3.3 Assessing the Roof Structure
