 Boght my '64 Shasta and PO had removed countertops and had a newer fridge rammed into place. It looks as if there was a box with tin, that I assumed was the vent for the fridge. I've seen this on a few other Shastas so I'm thinking it was part of the original design   im in the process of building countertops. I'm not trying to be a purist here, but I would much rather have a flat countertop and duct any heat the fridge gives off (assuming that was the original use) in another way. I'm reskinning so moving the exhaust is not a problem. I'm going to be putting in a 3 way Norcold 305. Can an anyone confirm my suspicions of this being duct for fridge (or maybe even heat from range)? Any issues moving lower and venting in a different way? Any thought on venting? |

This is how Shasta vented the gas fridge in our 64. Obviously bottom vent pulls air in top near the roof vents heat. The fridge sits about 3' off the floor.  I'm sure your fridge comes with some guidelines for venting. The box on the counter may not even work for a newer 3 way. |

The outside might give as much clue to the original as anything.  By 1964 the propane fridge was a fairly standard piece of equipment, although technically still an option. The icebox that preceded it did not require any venting. What shows in your photo seems to be a hood above the refrigerator mount. This same arrangement was used in my Airflyte, with an upper and lower vent through the wall. (The lower panel opens for access to the workings of the fridge.)   Upper vent is just a tin piece that points the air to the outside:  In the Airflyte, the upper vent is housed inside of a cabinet, but has the same type of step that your countertop would have, as shown in the other photos:  This venting is necessary not only for the heat, but for the exhaust from combustion of the propane-burning function of the fridge. The upper really should be kept as high above the outlet from the appliance as possible, so it may be possible to adapt it to the Norcold. I would not recommend moving the vent lower than the outlet from the Norcold however. The 16SC did not have a stove hood because of the location below the window. |

Thx Ten. Pulled up Norcold installation manual. Need 37" and this will extend above countertop. Looks like I need to build a vent box.

I would highly recommend getting a thermostatically controlled 12vdc fan for the upper vent if you are going to vent out the side. They are small, maybe 4 or 5 inch diameter fan blade and come with the auto-stat that turns the fan on and off as needed. Only about $50 if I remember right. Mine is called a Fridgecool. Made by Valterra. The better you vent your fridge, the longer it will last.

37 square inches in any shape? Does it need to extent to a certain height in relation to the fridge? I have wondered myself about what's needed. |

Well heat rises. Anything that get's in it's way will cause more heat to hang around near the top of the fridge for longer and have a harder time getting out. The more heat that stays in there, the quicker your fridge will melt down. Having a roof vent is the best. If you angle it out of the trailer you want the angle to be as small as possible making it as easy for the hot air to rise and escape as possible. The fan really helps a lot.
