Wadoy RV Furnace & Water Heater Vent Screens Kit — Stainless Steel insect guards, 3-size set with springs

Wadoy RV Furnace Vent Screen Kit is a stainless-steel set of insect and debris guards that snap into common RV water heater and furnace vents to keep bugs, birds and rodents out while allowing proper airflow.

Protecting vent openings on an RV prevents nests, dead insects and small animals from clogging exhausts or air intakes. This kit combines three sizes of vent screens, quick-spring fasteners and an installation tool so you can fit Atwood, Suburban, Duo-Therm and many other popular vent models in minutes. The screens are pressed from heavy-duty stainless steel to resist rust and hold shape in outdoor conditions.

Which vent models does this kit fit?

The Wadoy kit covers a wide range of common RV water heater and furnace vents. It includes two water-heater-sized screens and two smaller furnace screens designed to match the most frequent vent diameters and rectangular openings used by Atwood, Suburban and Duo-Therm.

• 8.5" x 6" x 1.3" screen for Atwood 6 & 10 gallon and Suburban 6 gallon water heaters
• 4.5" x 4.5" x 1.3" screen for multiple Atwood and Suburban water heater vents and battery vents
• 2.8" diameter x 1.3" tall furnace screens for Duo-Therm and Suburban furnace vents
• Includes six spring fasteners and an installation tool to attach to common vent openings

How easy is installation and what tools are needed?

Installation is designed to be quick and tool-light: each screen uses spring clips that hook into the vent opening. The included installation tool helps connect springs without scratching or dislodging the vent trim, so most users complete fitting in one to a few minutes per opening.

• Use the supplied installation tool to stretch and attach spring fasteners
• No drilling or permanent modifications to the vent required
• Typical install time: about 1–5 minutes per screen
• Fits behind trim inside the vent opening for a secure hold

What materials and durability can I expect?

Wadoy screens are stamped from heavy-duty stainless steel to resist corrosion from weather exposure and exhaust gases. The rigid construction keeps the mesh shape under impact and prevents small pests from penetrating the vent while maintaining adequate airflow.

• Stainless steel body resists rust and holds its form
• Mesh pattern sized to block insects, mice and small birds without restricting flow
• Spring fasteners are durable and replaceable if needed
• Compact profile (1.3" depth) fits behind most vent flanges

Will these screens affect furnace or water heater performance?

When installed correctly, these screens are engineered to allow necessary airflow while keeping debris out. They do not block the primary vent path; however, routine inspection is recommended to ensure no buildup of leaves, soot or other material that could gradually reduce ventilation.

• Designed to maintain exhaust and intake airflow for typical RV appliances
• Periodic checks and cleaning keep performance optimal
• If heavy soot or creosote is present, clean the screen to restore full airflow
• Not a replacement for required manufacturer maintenance or inspections

Who is this for: RV owners and managers who want a low-effort, long-lasting way to protect common water heater and furnace vents from insects, birds and small animals. It’s ideal for seasonal campers, full-time RVers, and fleet operators who need quick installs, corrosion resistance and compatibility with widely used Atwood, Suburban and Duo-Therm vent models.
