Step 1
MaxxFan requires a 14” x 14” roof opening, if you are replacing another type already installed, 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 cen-
tered in the roof opening with the metal clips facing the sides of the vehicle (not facing the front or
rear of the vehicle).
Step 2
CAUTION: When installing your Roof Flange, only use a caulking/sealant compatible with the
flange (plastic product) and the roof surface. DO NOT use materials containing solvents such as or
similar to Xylene, Toluene, Methyl Ethyl Ketone, Acetate or Acetone as they can damage the flange.
Also, Polysulfide (Thiokol) type sealants must be avoided. Silicone Sealants, such as G.E. Silicone II
(non-paintable) used for outdoor applications have proven to be suitable for this installation.

NOTE:
Refer to supplied Operating 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.
