How to Ventilate an RV Generator

How to Ventilate an RV Generator
RV generators are manufactured to draw cool air to the system. If a generator is not properly ventilated, the system may burn out, overheat and shut down. To prevent these problems from occurring, take a few steps to keep your generator cool and in working order. The process is easy and requires little more than the consideration of a few troubleshooting tips.


Difficulty: Moderately Easy

Step 1
Check that the area where your RV generator is stored has an allowance of at least 4 inches. The generator's access door must have enough space for ventilation to travel back and forth.
Step 2
Use an air pump to clean the cooling and ventilation air inlet of dust, debris and dirt.
Step 3
Route the exhaust. Mount a PVC pipe to the RV's siding. The pipe must extend above the roof. Use a flexible hose to secure the pipe to the exhaust port.
Step 4
Make sure the hot air is exhausted out the bottom of the generator. In most cases, this is a given, but if not, adjust accordingly so the exhaust travels out the bottom of the generator.
Step 5
Disconnect previously added extensions to the generator exhaust system. Extensions can damage fiberglass and paint, crack the exhaust pipe and route carbon monoxide into the interior of the RV--and reduce ventilation.
Step 6
Turn off the Auto Gen Start (AGS), which is designed to automatically turn on the RV generator. If you are in an area without ample ventilation, you don't want your RV generator to turn on automatically.
Step 7
Block fumes from the generator exhaust from entering the camper while you are asleep. The best way to do this is simply close all windows near the generator exhaust. Install a carbon monoxide detector inside the motorhome for added security.

Tips & Warnings

Carbon monoxide detectors are available at retail stores and online.
