32RLS Heat - Or Lack of it

[justdee]

I just went out and tested the heat circulation again.
I took a piece of toilet paper and cut the ends into slices so they would 'flutter freely'. With the heat on, I put the paper over each of the vents.
The one next to the bed came in 3rd with movement.
The bathroom was in 2nd place.
The vent underneath the coffee bar was the clear winner at #1 with a lot of movement and the noise from the air being forced out.
And lastly was the twin vents at the end of the island. Barely any movement, but once I sealed off one vent, the airflow increased out the other side and was noticeably improved with the toilet paper showing some movement.
I bet that this is as good as it is designed. Those island vents are the furthest from the furnace so it makes sense that they have the least amount of airflow.

Having the same issue. We have a 2024 Avenue 32RLS we purchased in Sept of this year and now that is it getting a bit cold, We are using the heater now and find that the only vents we have are 1 in the bedroom on the floor and 1 in the bathroom on the lower wall and the 2 vents at the end of the island. I don't think we have a vent at the base of the coffee bar. Now for the air flow issue. Our bathroom heater vent blows like there is no tomorrow (like an oven in there) and the bedroom vent blows ok but the 2 in the kitchen at the end of the island have just about no air flow coming out. I also covered one vent on the island side near on the stove side and it did help a little. I was looking at the vent connections at the heater and was wondering if anyone has thought about disconnecting the one hose that blows the hardest and connect it to the one connector on the heat unit that feeds the bathroom. Has anybody done this to get better air flow in the living room area and less in the bathroom ? I also looked under the island and the hot air that comes out of the vent just goes up into the island because there is no cover or anything to keep the heat from going up as heat rises. I have a call in to tech support at Alliance and will report back if there is an answer to the issue. Hopefully this is not too confusing. Thanks Alies !

we just purchased a 2025 370FB, first trip out was in October and noticed the furnace did not work at all. We took it to the dealer for this and other minor warranty work (front bathroom sink drain was never connected). Furnace works now but as others in this thread note, the airflow is severely lacking and almost no airflow at the island. It is a bit unsettling that this is a known issue at Alliance.

followup - rerouted some of the ducts at the blower box where it appeared some ducts were compressed by water lines or just bad configuration (90 degree turns with flex-duct constricts airflow) and sealed some small leaks with aluminum tape. result is some improvement in front bath and bedroom, half bath has the most air flow and heat, the island had no noticeable improvement. removed drawers in the island and vent grills for a better look. there is a thin metal box that looks it was built into the island but can not see or feel the flex-duct. in the basement the blower box has two flex-ducts routed to a metal box that goes toward the island some 20 feet away. Does anyone know if there is duct work from the basement to the island or is it a simple wood framed tube from the basement to the island under the floor. I am old enough to remember in the 70's and 80's some house builders would skimp on metal or flex-ducts by routing air through joists and stud spaces using the drywall to create a duct. these were extremely inefficient if not properly sealed during construction.

Folks, at least on our Paradigm, there is metal duct work leading from the basement to the island.
Our duct work is collapsed and restricting air flow. It is pinched together via some long screws that have penetrated the top and grabbed the bottom and collapsed it.
Repairs are on my to do list, but since we don’t winter camp much it is low on my priority list.
You can easily determine this by removing the island grates and placing your cell phone into the duct work and snapping some picture or grab a video.
Many others here have reported collapsed duct work as well.
I believe I might have previously posted a picture of our duct collapse, I must have deleted the picture on my phone by accident.

From a previous post.

As you will see it is pinched together.

2024 310RL Furnace issues

Purchased the above RV on March 6, 2024 and having trouble with the furnace. If it's really cold, the temp will increase about 5 degrees, then the furnace shuts off. If it's cool, and the furnace only needs to increase the temp a few degrees, it can do that and exceed the set point by 1 degree...

Thanks Bryan, I will check it with camera

After another chilly night in our 32RLS I decided to dive in and see what was going on. One thing that was immediately apparent was the mess of duct work connected to the furnace. The service manuals for the furnace as well as common sense says that you want to minimize bends in the duct work. When I got to the furnace - via the pantry - I found that there was a complete mess of bent duct work. It appears that when they installed the furnace at the factory they connected the ducts to the furnace outside of the rig and then shoved the furnace in. I have attached Pic's of before and after as well as the amount of duct work that was removed. Granted if you pull the furnace in the future you would have to access the duct work and disconnect it first. Hoping for a less chilly night tonight.............

Any tips for how to access the furnace via the pantry?

Will that's interesting. I have an older 32RLS and the cabinet goes all the way to the floor. So I was able to cut the back wall of the cabinet for access to the furnace. Have to say I have used that access a number of times. Sorry no good answer here......
