Bathroom floor vent in 3895 and probably other models

Cold weather has rolled back around and with it a problem I tried to solve last year but was advised in a post against my solution.

The floor vent in my bathroom for the propane furnace blows way too strong heating the bathroom up like a sauna. I bought a plastic floor register that will close but was warned against installing as it would melt in the heat.

I've thought about trying to fabricate some type of metal cap for what looks like a 4 inch round metal vent in a recessed box that feeds the 2 inch wide register, but access is limited.

Any suggestions beside slinging a wash rag over the door to hold it open???

I have about an inch of metal duct work protruding into the transition. That extra duct work could be fitted with a partial cap to block some of the heated air or a damper could be fashioned to fit inside it or a damper to fit the size of the transition.


A tin bender, sheet metal guy, could cut a sheet metal cap to cover the opening. He could solder or rivet a strap that could bend down over the outside of the duct that could then be screwed to the duct to hold it in place. A smaller cap could be cut to allow some heat to escape instead of closing it off completely.
Another option would be to have a rectangular piece of sheet metal could be cut to fit inside the transition. He could solder an axle down the middle of the long end, just like the old stove dampers were made. You could drill holes in the ends of the transition for the axle to sit. Then a little tang on the damper could be screwed to the transition to hold the damper in place.
All this would be under the register and hidden away.

First thing I would do is determine just how hot the air is that comes out of that vent. We use plastic furnace vents at home and I have an over sized gas pack to compensate for the lack of wall and ceiling R-value.

It wouldn't be too hard to fabricate some sort of damper to reduce the air flow to that particular vent. Surprised Dutchmen actually has the vent completely hooked up.

Could a wooden register work? There are some that are fairly flat so you would have to block some or all of it to control the heat.

Mike, I found a metal one at Home Deport, and I close mind all the way, and enough air comes out to heat the bathroom

I am unsure of where your vent is located, but I have thought about not only closing that vent, but cutting another vent just inside the bedroom. The small 2 inch line feeding the bedroom is quite anemic.

I also wonder that if you were to completely close that vent, would it cause an over temp within the furnace? There is a Temperature Limiting Switch...the lack of air flow combined with this switch could cause abnormal cyclic operations of the furnace. If I close the vent, I would look for a way to make another opening somewhere.

Cale, you are correct about the temperature limit switch, I have a friend that covered the bathroom heat vent and it knocked out that switch. They were on an overnight stay while traveling and had to take it the CW to get it replaced and it cost them a couple extra days on the road.

I only recently learned about the Temp Limit Switch when I was troubleshooting my furnace last month. Funny the things you learn about when working on other things.

That bathroom vent issue isn't just limited to your 3895 Mike. My 3605 has the same problem. Dedicated 4' vent going into the bathroom. 2" teed into the bedroom. I wonder what engineer figured that one out.
I'm looking into swapping the hoses around. Only nice thing is you sure don't need much hot water to shower with if the furnace is running.
