Refrigerator Installation question.

Hi Folks

I am hoping I can get some general advise on installation of a new refrigerator. I am installing a replacement refrigerator in 1973 Tradewind. It is a Norcold refer. I have the original upper plastic scope/baffle in place. The refer is a couple of inches larger so I am going to cut it down.


A question I have about the enclosure for efficient operation, is it really necessary I build a baffle of some sort to fill up the additional space behind the refer as the side of the trailer falls away from the top of the refer to the bottom. In other words because of the curvature of Airstream we canít get the back of the refer up tight to the wall top to bottom. The bottom being several inches away. Will this be a problem for the refer proper operation. The old one did not have any additional baffling. I hope my question makes sense; any other advice or precaution would be appreciated.

Thank You,

Tony

In general, the venting system originally in place in your '73 was a good one, and should continue to work as well or better with you new unit. I don't think any baffle is needed. However, they can be helpful with newer Airstreams which have some pretty marginally placed input and outlet vent locations, many requiring fans to move air through the system.

In the "old days" (1973) the vents worked very well as they were constructed with gravity ventilation.

You need to seal off the back of the refer completely to prevent the exhaust from the burner entering the cabin. The vertical air flow should be unobstructed in order that the heat transfers up and out of the roof vent. The floor vent should also be unobstructed.

During the install make sure that the rear of the Frig is isolated from the front area. The shroud should be connected with the air passage up to the roof vent, allowing the air flow to enter the lower exterior grill along the rear of the Frig upwards. Do not let the warm air travel up the rear of the Frig into the cabin. A little awkward to explain. I hope I have explained it clearly enough. If not PM me.

I can't believe that as I posted this post Twinkle basically is saying the same thing. My story is from personal experiences. Heat escaping over the cabinet into the cabin.

I guess great minds think alike and at the same time!

Thanks guys. So in summary the original set up is good even though the fall away of the sides causes more air space then the straight walled SOBs, no baffling needed. And just keep the back completely sealed off from the cabin.
