76 AS Sovereign
I'm going through every system on our AS to make sure everything works and fixing what I find.
For the furnace I found out that it has been upgraded to a NT-30SP.
Looking at the FSM I found the ducts going to the black and grey tanks, but I can't seem to find the duct going to the fresh water tank. According to the FSM it should be right up by the furnace, but I don't see it anywhere.
Does anyone have a picture of where this duct is so I can try and find it on mine?
Also, the FSM shows two lines coming off the side of the furnace and feeding into the duct that travels to the back of the AS, and one line coming off the opposite side and feeding to a short duct and then directly into a vent that blows into the front of the AS. Someone has switched this around. I have 2 ducts going forward into 2 vents (one has obviously been added), and then only 1 duct going to the rear. Where the 2nd duct should connect has been taped off.
So a couple of questions here:
1) there are 4 outlets from this unit. One going to the rear is blanked off. Should I add this duct going to the rear?
2) if I do that should I blank off one of the ducts going to the front?
