Step 1
Remove the old existing roof vent and remove all old roof sealant for a minimum of 2” entirely around the
roof opening.
Place the MaxxFan Roof Receiving Flange into the roof opening and trace a pencil line around it to verify
the clean seal area that will be required. Note that the Roof Receiving Flange must be centered in the roof
opening with the metal clips facing the sides of the vehicle (not facing the front or rear of the vehicle).

From MaxxAir Vent Corporation
NOTE
The
MaxxFan
installs into a standard RV roof opening of 14 by 14 inches.
To determine if your roof opening is correctly sized simply remove the interior ceiling garnish trim
ring of your existing roof vent and measure the ceiling opening or verify the opening is large enough
by sliding the
MaxxFan
interior Garnish trim ring into the opening.
Due to the rear exhaust louvers, the
MaxxFan
requires a roof that is clear of obstructions such as air
conditioners, storage boxes, etc. for at least 8 inches to the rear of the existing standard roof vent
flange outside rear edge.
The
MaxxFan
is designed for a minimum roof thickness of 1 1/8 inches to maximum of 6 1/2 inches.
If your roof thickness is less than 1 1/8 inches build additional thickness at the ceiling opening using
wood or other suitable material.
The
MaxxFan
requires a 12 Volt 5 amp service. Confirm that the circuit you intend to use will accom-
modate the additional service load. Use the proper gauge stranded wire for electrical connection.
