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
The MAXXFAN Dome
fan requires a
minimum 6 1/4 inch diameter 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
Prior to installing the
MAXXFAN Dome
in
the roof opening, apply a continuous strip of
BUTYL tape or equivalent to the underside
of the flange in the groove provided.
CAUTION!
When installing your
MAXXFAN Dome
fan, 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 3
When inserting the
MAXXFAN Dome
fan
into the roof opening:
•
orient the fan with the button toward
the front of the coach.
•
ensure that the fan wires are hanging
to the inside of the coach.
Center the fan in the opening.
Using the eight (8) screws provided, attach
the flange to the roof at each dimple location
along the flange.
Note: Opening the fan lid gives better
access to the flange for assembling the
screws.
Screw into the dimple to pierce the flange,
making sure not to overtighten the screws to
avoid cracking the flange.
STEP 4
After the
MAXXFAN Dome
fan 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 fan.
