View 24V Furnace & excess heat below beds.

[Nodak52]

I recently spent a couple nights in the Rocky Mountains where the temperatures dipped into the 20’s. I set the thermostat at 67° and slept comfortably but in the morning, when I opened the drawer below the bed (and above the furnace) my clothes weren’t just warm, they were hot! So I opened the drawer opposite and it was the same, hot clothing. When I got home I pulled the drawers out to inspect the duct work and everything seemed in tact and secure. Has anyone experienced this issue or have you had any problems or even fires?
