Furnace on 23b

[Revschuette]

We have a 23b and I noticed that when the furnace is running, there is much more heat blowing from the end vents (rear bed and dinnette) than from the vent under the fridge. Is this normal? There isn't much air flow coming from the vent by the fridge.
Thanks in advance.

Where is the heater located? Is it near where the vents that are producing higher air flow? If so, that is common. The vents closest to the heater have less ducting to travel through and therefore there is a greater velocity.

My 23B is the same way. I just figured that is the way it was designed.

Heater is located more towards the back. I would think there would be more flow from the middle vent than what there is. Just wanted to see if others have the same thing. It heats fine, was just curious if there was an issues or not.

That is correct. If you pull the decretive cover off, you will notice that the manufacture has installed a cap. The cap is not installed tightly so there is a fair amount of air that can slip past the cap. From what I can tell if the cap was removed there would be no pressure built up in the system to push the air through the ducts.

@ Jagiven.......there seems to be good flow at the back and front, just not at the vent below the fridge. Is that the same with yours?

[Jagiven]

Yep, that is the way they designed it. I would recommend pulling the cover for the furnace and see how it is assemble. To remove the cover it is just like removing the outside refrigerator access cover, so you need a coin or a key such as your cargo hold key, give the fasteners a ¼ turn and they will be free.

If my HTT was not in the shop right now I would take a photo of it.

Mine is the same way. Ours are ducted to promote flow from back to front and front to back to achieve good circulation of heated air.
