The MAXXFAN MINI Deluxe 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 MINI Deluxe sleeve into the opening.
The MAXXFAN MINI Deluxe is designed for a minimum roof thickness of 1 inch to a
maximum of 6 inches.
The MAXXFAN MINI Deluxe requires a minimum 12 Volt DC, 2 amp service. Confirm that
the circuit you intend to use will accommodate the additional load. Circuit must be fused
and use appropriate gauge stranded wire for electrical connections.

INSTALLATION INSTRUCTIONS
WARNING! TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO
PERSONS, OBSERVE THE FOLLOWING:
Installation work and electrical wiring must be done by qualified persons(s) in accordance with
all applicable codes and standards, including fire-rated construction.
STEP 1
MAXXFAN MINI Deluxe VENTS require 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.
STEP 2
Measure the thickness of the roof opening
and, if necessary, mark and cut the height of
the MAXXFAN MINI Deluxe sleeve per the
following table. NOTE: for curved roofs
measure the thickest part of the roof.

STEP 3
Prior to installing the MAXXFAN MINI
Deluxe hood portion over the roof opening,
apply a continuous strip of BUTYL tape or
equivalent to the underside of the flange in
the area under the screw location dimples.
Attach the garnish sleeve using 4 screws
provided in the hardware kit.
CAUTION! When installing your
MAXXFAN MINI Deluxe, 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
(MEK), Acetate or Acetone as they can
damage the flange. Also, Polysulfide
(Thiokol) type sealants must be avoided.
If in doubt, please contact the
manufacturer of your RV.
STEP 4
Insert the MAXXFAN MINI Deluxe hood into
the roof opening with the louvered section
facing the rear of the vehicle and centering
the hood in the opening. Using the twenty-
eight (28) screws provided, attach the flange
to the roof at each dimple location along the
flange. Screw into the dimple to pierce the

flange, making sure not to overtighten the
screws to avoid cracking the flange.
STEP 5
After the MAXXFAN MINI Deluxe hood has
been installed, remove the excess BUTYL
caulk that may have squeezed out. Using a
sealer such as Dicor self-leveling lap sealant
or similar caulking, apply a daub over every
exposed screw head. In addition, apply a
bead (approximately 3/16” dia.) along the
outside edge of the flange all the way
around the vent.
THIS COMPLETES THE ROOF TOP

STEP 6
Remove the 4 screws holding the plastic
cover in place and insert the 12 volt DC
power supply wires into the open hole in the
side of the molded box on the MAXXFAN

inside the molded box. Using the supplied
wire nuts, connect the Positive (+) 12VDC
supply wire to the MAXXFAN MINI Deluxe
marked “POS 12VDC” and the Negative (-)
12VDC supply wire to the MAXXFAN MINI
Deluxe wire marked “Neg. 12VDC”.
Insert the RJ45 cable plug into the

Secure the wires in the box by reinstalling
the lid ensuring the wires are routed through
the built-in strain relief section of the box.
