Fridge Vent

Post by **AlexInAVan** » 29 May 2006, 20:00

Ive got a 2 way fridge that needs installing. it came with a vent/flue thingy (pipe at 45 degree angle from the top of the back of the fridge). Is this all that needs to be fitted in order for the fridge to work or is there other vents that i need to fit? Are any vents needed at all, as i have seen some vans with no hole in the side at all!

you MUST fit the pipe you have. This is the one that ducts the poisonous burnt gas to he outside of the living area. This is often called a "lazy T".

Beyond that you ideally need a lower and upper vent so that cold air can be drawn across the fridge pipes at the back of the unit. If you get this wrong the heat is taken away and your fridge doesn't get cold. Get it right and you have a super efficient unit.

I don't have the lower vent but do have air channels to ensure a good quantity of cold air arrives at the base. My upper vent is lower than it should be (by about 25mm) so I have fitted a 12v computer fan to assist in getting the (now) hot air away.

have a check of this site.....

Its not that dangerous.

the lazy T design encourages the burnt gas out of the van. The hot air rises up the vertical and cold air is drawn across the top, the 2 combine and rush out the side. You can check its working by putting your hand over the flue vent after a couple of minutes. In fact, this is how we chack that ours is on - that's much easier than peering down the little site hole. The only real danger is if the flue gets obstructed and the burnt gas comes out the wrong side of the T but the design of the flue covers reduces that chance to a minimum. If the flame goes out, the thermocouble in the flame turns off the gas.

The venting is not so important as it is not a safety feature but a performance one - but not one I would look forward to doing. I already had a vent there.

letting the heat from the exchangers into your van helps winter warming
