Drain plumbing for under counter steam oven

3 years ago

last modified: 3 years ago

Hi there! I would really like to go with a plumbed steam oven for my kitchen renovation if possible, but it will not be adjacent or near my sink. There will be a 12 inch cabinet to the left side, but I have a steel I beam in the basement I won't be able to plumb though.I was wondering what the requirements are for this drain since I assume it's only discharging condonation from the steam, not large volumes of water. Do I need to run a vented p trap line as if a sink were there, or could I just put a simple p trap in the basement and connect behind the oven? If I have a pvc p trap do I even need too bend the supplied drain hose as well since nothing else is connected to that p trap anyway?I tried to make some quick sketches showing the situation and some options being considered. Blue is pvc, red is the supplied drain hose.Thank you!

I would really rethink this mounting position, ideally it should be in an oven cabinet at a traditional wall oven height. As well this might alleviate your drain run problem.

Gagg Steam Oven - Under Counter Install?
Q
Comments (5)
The condense button floods the oven with cold water which disposes of some of the steam prior to opening the door. But, even with this process a lot of stem escapes out of the top of the oven when you open the door. I would not even consider mounting this oven low. My husband opens the door without condensing and the steam that escapes from the top is immense. I would hate to think about what that might do to a face.

We've had ours installed undercounter and in use for two years. We attached it to the sink drain; just made sure there was a steady incline down from the appliance. And--we're getting ready to do it again in a new kitchen. It is a bit more difficult to operate the controls since they slightly slant downward, as jakvis mentions, but fairly quickly you learn to set the controls without much need to look. This istallation set-up allowed us a nice drawer underneath to hold racks and pans. You MUST be careful about standing back to open it...the steam could burn your face or arms as it rises.

Would under-counter mounting a Miele combi oven harm a countertop?

I don't think it would pose a problem to the counters, but I don't feel comfortable answering that. If you call Miele, you will get good advice, I think. The ventilation is for the electronics, NOT the steam. I retrofitted a combi steam in an existing cabinet, and I had to research that question. Basically, you need air circulation for electronics behind the oven.

Thank you- I called Miele customer service this morning to ask about under counter installation and the rep said it was technically ok, but not recommended for two reasons... one being the handle sticking out, the other is that the digital display would be inconvenient at that height. I'm only 5 feet tall so it's not terrible for me, but I do see his point. I don't have another place to put the oven unless I were to add a cabinet for it, which is not ideal.

Thank you, and ideally I agree.

Unfortunately my layout is fairly restrictive so if I want to have the option for a steam oven (and I really do!) under a counter is really my only choice, and this area would be the closest to the correct side for plumbing.

I have the Miele CSO and they have approved/detailed specs for under counter installation. Mine is in the island, under the counter and next to the prep sink, so I was able to tie into the water line and drain. In a perfect world it would be slightly better to have the oven raised up a bit, but it was a worthwhile compromise to get a steam oven and to be able to have it plumbed.

What CSO are you getting? What do the installation specs say?

I am going with a Miele as well, and at least so far I've only seen a spec describing installation assuming there is an adjacent sink. So I and pretty confident the first drawing would work since that would pretty much be equivalent to a sink drain, but I'd like to know if I have to do something that extensive.

I also reached out to a local Miele retailer / installer but haven't gotten a response yet.

That’s not vented properly. You will have issues. Hire a plumber to run the drains and venting if you do this.

We got our first CSO in 2005..the Gagg plumbed Version. At that time undercounter installation was a no-no due to the risk of getting burned by rising steam upon opening the door. i would not do it. In addition, if something is going to go wrong with your CSO..it is more than likely related to plumbing. I don’t know where I read that, but I do believe it.

i have an unplumbed CSO now and honestly I don’t miss the drain or the plumbed version. Love my CSO.

How did you end up draining with venting? I have a similar situation for my CSO location. Does Miele sell a longer drain hose than the approximately 10’ hose?

The standard dgc drain hose is 5m (10ft) but they do have a 7.5m (15ft) one. I installed a Miele DGC under counter and didn’t have any issues with drain.
