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.
The MAXXFAN is designed for a minimum roof thickness of 2 inches to a maximum of
6 1/2 inches. If your roof thickness is less than 2 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. Conrm that the circuit
you intend to use will accommodate the additional load. Use the proper gauge stranded
wire for electrical connections.
