15 - Corvallis, OR, Day 3

I needed warm, sunny weather to soften the Dicor sealant used to waterproof the original vent. I used a putty knife to carefully remove the warm sealant so I could get to the screws. Removed the screws and carefully pried the old vent off of the roof. The existing putty looked to be in pretty good shape. It was only a couple of years old as the roof was replaced back in 2016. After the new vent was put in place, I put in the screws and hand tightened them to make sure I didn’t crack the plastic frame. The metal plates are for the vent cover allowing the roof vent to be open in inclement weather. Tomorrow, I’ll seal the new vent with some Eternabond tape and Dicor self-leveling sealant. The Eternabond tape I have is 4” wide. I’ll cut it in half lengthwise as 2” is sufficient.

This vent needs 12VDC as it has a fan motor, temperature sensor, rain sensor, as well as a motor to open and close the vent. The height of the ceiling where the vent is installed is around 7 1/2 feet so being able to operate it without a step stool is a benefit. The nearest always-on 12VDC is at the reading lights on the rear overhead cabinets. I fished the wires through the ceiling into the cabinet. I then removed one of the lights and drilled into the cabinet so there was a path for the vent power wires.







Just about finished. This evening, I used Eternabond tape to cover the edges of the new vent as well as the older bathroom vent. That is a different model of Fan-tastic Fan. Completely manual and only one speed (of three) works. Maybe one of these days I'll take it apart to fix. I also picked up a vent cover for this one as well.

I tried out the new fan with the fancy remote and it works pretty well. The thermostat is adjustable in 2.5°F increments and the fan has 14 speeds.

Well done on the vent replacement.

Good to see you guys yesterday Richard. Don't get sunburned working on the roof of the RV.

Looking forward to dinner on Thursday.

Great job on the Fantastic fan. We have them and they are wonderful. On two of ours we were able to add the vent covers so we can use them in the rain. The third fan vent was too close to the AC unit for a cover to fit.

Thank you. One benefit for parking in the overflow lot is no one around to complain about you working on the RV.

RichardM said...

It was hot and very bright on the roof. And it was good to see you two again.

RichardM said...

We have one already but it didn’t have a thermostat and only ran on high speed. The trailer will be in storage for a while so I wanted to leave it open with the thermostat set around 80°F or so with the fan on low speed while in storage. Keep it from getting too hot inside.

Good plan...does it not run your house battery down, or will it be plugged in? Just curious.

RichardM said...

I have 400 watts of solar on the roof charging 430 ah of batteries which would be more than enough to keep things going without being plugged in.

Lynne Goebeler said...

Ah right...how could I forget the solar!
