Designed for standard 14" x 14" RV roof vent openings
This roof vent fan is intended for standard 14" x 14" RV roof openings and is commonly listed for roof thicknesses from 2" to 6-1/2". Always measure the roof opening and roof thickness before ordering. This model is manual opening and does not include a rain sensor or remote control.
Before Starting: Work safely on the RV roof and disconnect 12V power before wiring the fan. Use sealants and installation methods compatible with the RV roof material. Basic Installation Steps: 1. Confirm Fit: Measure the existing roof opening and roof thickness to confirm compatibility. 2. Remove Old Vent: Remove the existing vent, interior garnish, screws, and old sealant as needed. 3. Clean Roof Surface: Clean the roof mounting area so the new vent can seal properly. 4. Prepare Wiring: Confirm 12V DC power and ground wiring are available and properly fused for the fan circuit. 5. Set Fan in Opening: Position the MaxxFan Plus over the 14" x 14" opening and check alignment before fastening. 6. Seal and Fasten: Apply compatible RV roof sealant and secure the vent according to the installation instructions. 7. Connect Power: Make the 12V wiring connections using proper RV electrical practices. 8. Test Operation: Confirm fan speeds, intake/exhaust direction, thermostat function, lid movement, and seal integrity.
