Range Hood Question

[Glennman]

I see some RVs have vented range hoods. Some are probably vented to the outside, some recirculating. I know the recirculating ones have a certain value as grease would collect on the screens and would subsequently be cleaned. The ones that vent outdoors both collect grease and vent smoke to the outdoors, which I think is very desirable, similar to what I have in my house. Most building codes require a kitchen to have ventilation to the exterior, but not necessarily via a range hood. People can install a fan in the ceiling and accomplish the ventilation requirement. I suppose the Fantastic Fan (or whichever) would be equivalent to a typical kitchen fan mounted at the ceiling.

Are you bus converters or owners out there installing range hoods; are they vented to the exterior; recirculating; none at all; or are you only relying on the ceiling mounted exhaust (?). I'm thinking the ceiling exhaust fan is sufficient, especially when I research the cheap junk that is available out there.

We have an over the stove/oven outdoor vented range hood with lighting & 2 speed fan - it expells most of the heat & cooking aromas before they "get away". We also have powered vent hoods in the ceiling. They work great to get the popcorn smell out when microwaving as the stove hood don't catch that. The two different hoods have different purposes. Code? Whats that? Lol

 The further that cooking gases, grease, moisture, steam and stink goes, the more of the coach permanently picks up the stink.

Range hoode and external exhaust catches it all as early as possible.

Old buses stink for a number of "unknown" reasons...

This source is known...

Defeat it!!

Happy coaching!

I've had three different iterations of cook top venting...

1) Our 4106 had a Jenn Air range with down-draft venting. There was a pop-up 'vent hood' at the rear of the cook top, with an extractor fan below the counter top. The air exited out the bottom through the bay and then through the floor of the bay. An oil-catch jar was in the system.

2) Our 4108 had a 6-inch 120v exhaust fan on the ceiling over the range, as well as a 12v MaxxAir fan a few feet away.

3) Our Airstream has an externally-vented range hood over the cook top.

Of all three, the Jenn Air out-performed the others hands down. Not only did it do a great job of removing the odor, grease, heat, etc. it did it all without having to mount anything over the cook top. If I were to design a bus from scratch it would be my first choice, but not sure if they can be retrofitted easily.

The Airstream's traditional externally-vented range hood works well. It does exactly what you'd expect and is very similar to a household unit. There are pre-made external vent covers with a lockable flapper that make these easy to install.

The ceiling vents in our 4108 worked, but as already mentioned being a bit further from the source they allowed odors, grease, etc. to make contact with a much broader surface. By the time the ceiling vents have removed all the moisture and such it's already spread through the cabin somewhat.

My recommendation would be for a traditional range hood, and one designed to work in an RV would be able to operate on 12v with no converter necessary.

The donor 5er that I tore up for parts when I built Honeysuckle Rose came with a ridiculous fume hood that sucked fumes through a filter and then blue them out the top.  I plugged the top and redirected the fumes out the side of the bus above one of the false windows and under the original eyebrow.  It works fine and isn't visible from the outside.  Jack

Sorry about the width of the pics. I don't know what happened but the slide bar at the end of the post allows viewing of the right half of the pics.

The plywood was replaced with a sandwich of sheet steel to rep[lace the glass, 2" of foam insulation and an inner layer of stainless steel as a back splash.

I have always used a house type of system. Fantastic vent recommends never to use their fans for cooking exhaust.

[Glennman]

Thanks for all the responses. It looks like I will need to buy a hood of some sort (preferred to be 22" wide) and modify it to suit my needs. With my method of leaving all the windows in place, I cannot go out the wall (the steel between the top and the windows and the roof is very formidable. To get something out of what's left of the "wall" is undesirable). The RV hoods I've seen all appear to go out the back. I suppose I can change that to go out the roof, which really should not be a problem. I can certainly understand that using a Fantastic Fan 3 feet from the range is not a good plan, and I definitely don't want those mysterious odors that build up over time. I really like ol'trunt's hood! Thanks eveyone.

The hood in mine vents out the top so they are available. Sorry I can't give you any more details as the bus is 1300 miles away.

[freds]

What's the air flow path in your current hood?

SWAG from looking at the picture it looks like it vents out the back. Does it actually vent via the roof?

It sort of looks like you have a hood it just needs a filter and a fan?

Did a little searching most of the range hoods that vent out the top are "under cabinet" units.

Here's some option's if you have 120v available when cooking.

If you're producing "fumes" when you cook, you're doing something wrong.

[Bill Gerrie]

You always produce some form of cast off when cooking. Just look at the filters in a range hood after a period of time. Quite loaded with grease. This is the main reason to exhaust as close to the stove as possible.

[Dave5Cs]

We just open the window right behind the stove and have a muffin fan there we turn on and it all goes outside.

[Iceni John]

All the vent hoods I've looked at seem very badly designed and poorly made, so I made my own instead.   There's an openable window behind my cook top and an overhead cabinet above it, so the window is opened down to its first detent leaving a few inches open, and a battery of eight computer fans blow smells straight outside.   When I pull the control handle the outside weather/rain flap opens and the four low-speed fans start, and when I pull the handle further the four high-speed fans then also start.   12V computer fans are only a few dollars each, and they're quiet and use hardly any power.   I also made a shower vent using two more computer fans that blows steamy air out the same window.   They both work well and were cheap to make.

[Jim Blackwood]

Your range and your shower are both under the same window?

Cool.

On both the bus and truck conversion, I did the same thing. A 120vac non vented hood with a Fantastic roof vent above. Did not want another hole on the outside. Just open one window, turn on the hood, turn on the vent to suck things out. We do not deep fry or cook bacon or hamburgers inside. Good Luck, TomC
