Heater tubing under floor of Bighorn 3760

[kbausano]

While roaming around behind basement walls searching for unused space, I noticed a loose pipe (pic #1) that may have been the cause of certain airflow issues.

The question I have (pics #2 & 3) is whether anyone has this 1.5” piping running to any particular fitting to heat the basement - or are they all left ‘open’ such as this?

That "open ended" 1-1/2" pipe is considered to be the "heated underbelly" for what it is worth.

The 1-1/2" duct is stubbed out in the underbelly to provide warm air flow into that area.

I get the concept - just wondering if this air duct is intended to be simply dropped into the belly ‘naked’, or connected somewhere to a fitting of some kind?

It's just left hanging there and air flows out of it. It's not supposed to be connected to anything.

Thanks for that assurance, Dan!

1st pic the duct should be connected to the plenum.

I have same model- should be connected to heater then yes dumps into area to heat belly/basement- bathroom gets way to hot - planning on installing t off line to bathroom and putting more into basement- or possibly feeding into line that goes to back by couch - that's the coldest part of trailer- earlier in yea when it was mid-high 20's - set heater to 48 and put remote temp senders in belly area and basement and they stayed 40-42 range

you can move the wall back very easily and gain nearly a foot of storage space- I moved transfer switch and converter and surge unit further over and and currently making plans for using that big area for tool/bbg storage or for some additional batteries/inverter/solar controller.
