refrigerator
Andyg the fan I used was in a kit from Norcold. The kit is for the N600 series (6.3 cu. ft.) It came with the temp switch and all the wiring. I think it was around $90. I also followed the installation instructions and added two sheet alum baffles to control the air flow around the coils. The other pictures are of the bath wall just aft of the fridge. You can see a test piece of plywood to make sure I will be able to use 4" duct from the furnace . I trimmed the black plastic collar on the duct outlet in an effort to smooth the bend. It seemed to work fine and should provide lots of warm air in the bathroom. I will also need to attach the hose to the outlet before I screw the plywood to the wall. The water-heater exhaust will go out a 2" tail pipe. I can have it dump out behind the back of the rig. With the tankless water-heater the burner will only burn when hot water is flowing.
