We decided we should replace the exhaust fan in our bathroom. The one that came stock with the RV you had to manually open and then click a button to start up the fan. We already had a MAXXFAN in our kitchen and thought we should replace the one in the bathroom with the same kind.
This fan is super cool (ha! Get it?) because it has a rain cover built in, 10 speed exhaust and intake fan, thermostat, and a remote controlled electric opening. Plus, it’s super quiet in comparison to the old fan and way more efficient too!
Today we’re going to walk you through the process of how we got the fan installed. It’s a fairly simple process but does take a bit of time. Side note: we are not professionals, we enjoy doing projects ourselves, that being said do your research and if you feel like you’re not able to do this on your own get some help from a professional!
Supplies You’ll Need:
- Wire stripper
- Joint knife (or similar flat metal tool)
- Dicor butyl tape
- Dicor roof caulking
- Exhaust Fan
- Start by removing the inside trim of the old fan
- Turn off electricity that goes to the fan so that it is safe to work with
- Disconnect wires (you may have to snip them if they’re crimped at the top like ours were)
- Once you have the wires disconnected, there should be nothing on the inside holding the fan in place
- Take the roof receiving flange and apply your dicor butyl tape all the way around it
- Grab all needed supplies and head up to the roof
- Remove vent cover if you have one
- Pry up old dicor and remove the screws all the way around be careful not to damage the roof
- Once all the screws are removed and enough of the dicor is off, you should be able to lift the fan out of the opening in the roof
- You’ll want to make sure enough of the dicor is off to ensure you get a nice tight seal between the roof and the roof receiving flange
- When you have the receiving flange in you’ll then add in all the screws
- Now that the screws are all in place, cover each one with some dicor. This ensures that no water will get inside the screw holes
- Next, you’ll want to fill in the gaps between the old dicor and new dicor
- Place fan down into roof receiving flange
- Screw in the last 4 screws into the metal brackets
- Head back inside
- Strip wires
- Twist the negative wires together and the positive wires together
- Twist the wire nut over the wires you just twisted together until it won’t twist anymore
- Screw in the new trim piece (you may need to cut it down if it’s too long)
