34RLSA Furnace Duct
Working through the many usual quality control issues on our new RV…
Noticed that the furnace air flow is half of what we’ve seen on previous RVs. Got to looking closer at the short duct that runs from the bottom of furnace to the main duct line, and found that it is only about 1 ½” high, whereas the main duct is 4 or 5” high. It appears they had to shorten the duct height to get clearance over one of the holding tanks. I’m going to get deeper in there today and measure the square inch area of that short duct to see if it even meets the minimum size specified in the furnace manual. Thinking that this might also cause the burner to short cycle due to restricted air flow/heat exchanger hi-temp.
I'm thinking that a couple extra 4" round flexible ducts from the furnace to the main duct would be the best fix....
Can someone with a 2014 RLSA take a look at their furnace duct in their basement and see if this is common to our model?
