Check your heating ducts

We just took delivery of a 2022 Quantum JM31 and I now have it in our garage doing repairs and mods. While installing a washer/dryer I discovered that the heat duct for the bedroom was in an S-shape and kinked to the point it was almost closed. I pulled the duct out and discovered it was about 5 feet to long. Cut in off and now it looks nice and straight. If you have restricted air flow on one of the heating ducts you might want to pull it out and see how long it is.

Also make sure they are securely fastened to the heater itself, found 2 of mine not connected, they won't come off now.

X3 on this. Two of mine were not connected. Also had a few extra feet of hose.

Fix any kink, but the hose is extra long on our 24.1 so it contacts the fresh water tank, giving a small bit of no-freeze affect.

It's amazing what you find behind those walls. Orphan screws, butt connectors, wire insulation and handfuls of sawdust!! ��
