Dometic Ultra Breeze Vent Covers & Optional Bug Screen Guide

Dometic Ultra Breeze: Choose the Vent Cover or Bug Screen

Replacing an RV roof-fan rain cover or adding insect protection? Dometic's Ultra Breeze range includes exterior vent covers and a separate grille-mounted screen. The model number matters: U1400WH and U1400BL are covers, while U1550WH is a bug-screen accessory.

Three details to check before buying

1. Existing vent and roof opening

Identify the roof-fan model and measure the surrounding roof area. These exterior covers are listed for standard 14 × 14-inch vent installations, subject to the actual mounting configuration.

2. What is damaged or missing?

If the large exterior rain cover is broken, select a model-1400 cover. If you have an Ultra Breeze cover but only need the grille insect barrier, compare the U1550WH screen.

3. Mounting and clearance

Check brackets, screw locations and clear space on the roof. An existing clamp-type fan can require a different mounting procedure than a flange with suitable screw holes.

Screen versus cover: Dometic's installation manual identifies the insect screen as optional. Check the exact package contents of the cover you're ordering; do not assume a separate U1550WH screen is included simply because the illustration shows one.

How the components work together

U1400WH and U1400BL: These are white and black versions of the model-1400 exterior vent cover. The housing is intended to help shield a roof fan from weather while allowing ventilation through the grille. Select by the exact part number and confirm the fan, roof opening and mounting hardware.

U1550WH: A separate white mesh insert for the Ultra Breeze grille. It does not replace the large roof-mounted housing, the vent fan blade, the fan motor or an interior ceiling grille.

The fan itself is not part of these cover products. If the existing fan does not run, diagnose that issue separately rather than treating an exterior housing as a fan replacement.

Installation notes from Dometic

The official Ultra Breeze instructions show the model-1400 cover seating on the fan's molded mounting points and securing with the specified rivets. They also distinguish other mounting procedures, including clamp-style fans where drilling may be required. Use the correct instructions for your particular fan instead of assuming all installations are tool-free.

The optional screen slides into the vent-cover grille from below and clips into the opening after the grille is in place. Confirm the clips and screen seating before reinstalling the exterior cover.

For the manufacturer-specified hardware and installation sequence, consult the Dometic Ultra Breeze 1400/1500 installation manual (PDF).

Common selection questions

Do I need the cover or the bug screen?

A cover protects the exterior fan opening; the screen fits into the cover's grille. Choose U1400WH or U1400BL for the housing and U1550WH when you specifically need the white Ultra Breeze grille screen.

Are the white and black U1400 covers different mounting types?

The listings identify them as colour alternatives within the model-1400 cover family. Confirm your original fan and mounting arrangement rather than choosing by colour alone.

Does U1550WH replace the inside fan screen?

No. It is a screen for the exterior Ultra Breeze cover grille, not the interior fan's trim or screen.

Is mounting always possible without drilling?

Not always. Dometic provides different methods based on the roof-vent construction. Refer to the installation instructions before modifying the vent flange.
