Furnace ducts on 2002 Windsor

[MSHappyCampers]

Does anyone have a diagram on how the furnaces ducts are run on the 2002 Windsor?

I want to know which ones are supposed to be supply air and which ones are return air.

Joe, perhaps your coach is different, but mine has a Suburban furnace (tightly squished, but within clearance specs) under my Samsung RF18 fridge. It has NO return ducts. 100% of its intake air (inside air from the coach, NOT combustion air) comes from the grille built into the top of the unit. Some of the ducts that seem to "disappear" are routed to storage compartments beneath to prevent freezing in the winter.

BTW, I once hoped to improve its heated air delivery volume by replacing the convoluted flex hose with PVC pipe, which was very smooth-walled. The improvement was noticeable, but not worth the trouble.

Hi Van! Thanks for the reply. Both our furnaces have access door outside. I don't feel any airflow from some of the vents inside so thought these might be return vents. Would sure like to know!

Good afternoon Joe; Glad to see your headlights came in and will be interesting to read about your install. As to the furnace. If your 02 is anything like my 01 Windsor, the hot air is forced by fan through the ducts to the vents in the coach. If your furnace is located below the refer like mine and has the wood grill over the access to the furnace itself, that is your could air return. As far as I know with our Windsor's, no cold air returns through any ducting, but I could be all wet. Hope you find this info useful and good luck with your project this weekend.

I agree with 8.3Oilbuner.

I've only have one furnace under the refrigerator. I just replaced the Norcold and had to disconnect the ducting. There were two 3" duct lines going toward the front to the registers under the cabinet the table is attached to. There was a ~1.5' duct that went to toilet room. There two 3" ducts going to the rear, one went to the basement wet bay and one to the rear bed room. The return air is drawn in through the large vent under the front of the refrigerator.

Here is some info on the Surburban Furnace which may help.

On my 03 Windsor the cold air return is also under the fridge.
