3. Installation Guide
Follow these steps for proper installation of your FOGATTI RV Water Heater Door Kit. Ensure all safety precautions are observed during the installation process.

3.2 Step-by-Step Installation
- Remove Screws: Remove all screws from the mounting flange. You may need to remove the door hinge clip and then take down the door for better access to the screws.
- Install Filling Blocks (if needed): If the original cutout sizes are larger than the machine, you may fill the gap by attaching wood blocks to the RV body. Make sure to tighten them up with screws. FOGATTI filling blocks offer superior shock absorption, corrosion resistance, noise reduction, and are flame retardant compared to wood.
- Install Trim Ring: Slip the trim ring from the back of the enclosure to the RV water heater door. Apply a seal strip to the back of the trim ring.
- Apply Sealant: Apply sealant around the mounting holes on the RV wall to ensure a watertight seal.
- Place Water Heater: Put the RV water heater body inside the (new) RV door frame. This RV water heater must be installed at the angle shown in the video, not tilted or sideways.
- Secure Water Heater: Tighten up with screws provided, and then hinge the door back to the flange together. Screw the water heater to the RV.
- Close Door: Close the water heater door and ensure the latch engages securely.
