New Furnace
Review by
The swop of this furnace for my old 14 year old furnace was simple.
the Propane line and 4 wires. I left the case in the RV as the duct work was attached and I saw no benefit to changing it.
Project took 2 hours most of that time trying to figure out which of the 2 blue wires was which.
Furnace runs great, Don't forget to turn the switch on the unit to ON before buttoning up the Job.
