Furnace vent screens help keep insects and nesting debris out of an RV's exterior furnace openings. Valterra offers several stainless-steel designs, but the correct screen depends on the vent shape, dimensions, access-door arrangement and furnace series. A Suburban round exhaust and an Atwood Hydro Flame rectangular vent do not use the same screen simply because both are RV furnaces.

How to distinguish the screen styles

Rectangular furnace openings

The A10-1300VP is a rectangular screen for compatible Coleman, Sol-Aire, Hydro Flame and Suburban vents with the matching opening. The A10-1302VP is intended for a different Atwood Hydro Flame 8500-series access-door layout, while A10-1305VP is for matching Atwood AFMD vents. Compare the actual opening size and cover arrangement instead of treating these rectangular screens as interchangeable.

Round furnace openings

A10-1301VP contains a pair of smaller round screens for suitable Suburban and Duo-Therm two-vent outlets. A10-1303VP is a larger round screen for the matching Suburban DD-series vent. A10-1304VP is a smaller round design for Atwood Hydro Flame furnaces without an exterior access door. Each part has its own manufacturer-specified dimensions.

What the installation parts do

Furnace vent opening

The existing exhaust and intake arrangement dictates which screen design fits.

Stainless mesh screen

Covers the matching opening to deter insects and nesting pests.

Spring fasteners

Retain the screen at the correct mounting points when installed as directed.

Installation tool

Helps position the supplied mounting springs in accordance with the instructions.

These components are an identification overview, not an appliance exploded diagram. The bug screen is an exterior protective accessory, not a replacement for the original combustion-air or exhaust components.

Before ordering and installing

  1. Locate the furnace identification plate. Confirm the manufacturer and exact model or series, particularly on Atwood Hydro Flame and Suburban furnaces.
  2. Identify the access-door style. Atwood Hydro Flame vents with and without access doors can require different screens. AFMD and Suburban DD have their own listed configurations.
  3. Measure the exposed vent opening. Compare shape, depth, outside clearance and the screen dimensions above. Do not order by appliance brand alone.
  4. Follow the spring-fastener instructions. Allow the furnace to cool and secure each screen to the designated points without modifying the appliance vent.
  5. Inspect at least monthly. Clean leaves, insects, dust and nesting material from the mesh so airflow remains unobstructed. Never operate a furnace with a blocked vent.

Other RV appliance vent protection

For water-heater vent openings rather than furnace exhausts, see our Valterra Atwood and Suburban water-heater bug screen reference. Water heaters and furnaces have different vent requirements, so match each screen to the correct appliance.
