It's not hard to vent the refrigerators, mine is a household type but it's got the added feature of having a microwave mounted on top of it, we added a thermostatically controled fan to exhaust the heat if it built up and reached a given point.  Because it is all built into a cabinet venting it made sence.

Ace,

Heat removed from inside the fridge has to go someplace inside the bus if there is no vent.

At least there is no CO problem though.

If you check the label on the refer you will find a wattage number.  That is the heat you are dumping inside the coach that AC must deal with in the summer.  Winter it's great!  Maybe a controlable exhaust duct?

This is fundamental but some don't know it.  Rule: any time you have a flame touching metal you will generate carbon monoxide in some quantity.  Gas refrigerators were very popular way back.  Sooooo many consumers were killing themselves that the Fed made them illegal for domestic use.  I guess RV's are an exception.  Industry still favors absorption cooling where it is appropriate.  Ya gotta vent the gas fridges or they won't work well and they will kill you.  Convection air flow for the vent means you must vent thru the roof.  You can't rely on a power vent for gas.

    A friend installed a RV type refrigerator in his eagle and installed the top vent in the wall right below the roof (Manufacturer said this was acceptable).  He had trouble with the refrigerator cooling properly and added an electric fan inside the wall mounted top vent to push the hot air out. This made a big difference in cooling ability. He later installed a roof mounted vent (without the electric fan) and has had no problems since.  Just reporting an actual case, YMMV  Jack

Norcold says a side vent can be used but advises against it.

If used the specs for the air duct are very specific.

Even then they say it isn't as efficient as the top vent.

The top vent duct dimensions are also quite critical for good exhausting.

I've had no problems with mine, it works better on gas than on AC. Hardly works at all on DC.
