Step 1
Remove the old existing roof vent. Remove all old roof sealant for a minimum of 2” entirely around the
roof opening.
Place the MaxxFan Roof Receiving Flange (ref. photo #3) 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).

NOTE:
Refer to supplied attachments for further instructions regarding the model you have
purchased.
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 exhaust/intake louvers that face the rear of the vehicle, the
MaxxFan
requires a roof
area 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 outer rear edge.
The
MaxxFan
is designed for a minimum roof thickness of 1 1/8 inches to a 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 minimum 12 Volt DC, 5 amp service. Confirm that the circuit you intend to
use will accommodate the additional load. Use the proper gauge stranded wire for electrical
connections.
