We're replacing a very old double oven with a single Thermador unit,
and the installation spec
calls for installing 2x4 supports. I can't get anyone to do it in time
for the new unit's arrival so we have to do it ourselves.
What method/hardware should be used to secure the supports to the
cabinet walls? The diagram suggest that the 2x4 be perpendicular to the
wall, but that would seem to require some pretty big screws. What's the
best way to do this?
Heres the install doc:
Can't see your cabinets, but can yo trust their walls to bear the
weight? If you can, I would use some sturdy "L" brackets to support
Looking at the diagram on page 4 I see two "legs" cut to size from the
floor level to the 2x4s . Those legs can also be 2x4. I would put
also 2 legs on the back and two more in the middle and secure all 6
to the 2x4s with the brackets.
So, 6 brackets for the legs, 6 to the cabinet wall ( 1 at each end and
one in the middle) and enough screws to put all that together.
Shouldn't go anywhere, but I would also secure the foot of each leg to
the bottom of the cabinet.
What about the electric box, is it in a good place for the new oven?
Hope this makes sense
I don't know yet about the electrical box because we haven't removed
the old oven yet (they're coming Monday). The only thing with what you
say is that we wouldn't be able to put another oven in the lower part
of the cabinet, which we may want to do. I would assume that there are
only post supports in the back in the diagram so you don't block the
use of the lower part of the cabinet?
Currently there is a double oven that sits on a shelf (which is the top
of a drawer located under the current oven. Wouldn't that imply that a
shelf screwed into the sides would be enough to support a single oven?
(I assume there is some sort of framing around the cabinet, but its
under a fancy veneer and I don't want to risk damaging it)
One thing of note: The cabinet is in the corner, so the back of the
cabinet is not flush against the wall. So wall studs will not be able
to be used. I think there is a bit of space behind the cabinet.
Do you know the dimensions of the future bottom oven?
you may be right.
Not sure which one you're getting, but the heaviest single is 240
pounds. Do you know how heavy is the old double? Probably heavier..
Anyway, is that shelf at the right height (dimension D on page 5?. If
not you may have to put 2x4 s or another shelf at the correct height.
When you remove the old one, you should be able to see how that shelf
is secured to the cabinet. My guess is screws or nails in the frame of
the cabinet. you could secure those 2x4s or the new shelf the same way
May want to choose the lenght of the screws very carefully.
Also, you'll probably be left with a hole in that cabinet (the
difference in height between old and new ).
I am in the middle of doing the exact same thing, including installing a
Thermador oven. However I am changing from a 27" wide to a 30" wide and have
had to build a new cabinet for it.
Don't expect to accept delivery, wire it up, slide it in and turn it on.
Your old oven probably has a fuse/breaker box somewhere close to the old
oven. Your new Thermador may have something else, or a plug that will need a
matching receptacle. I haven't received mine yet, so I don't know either,
and the manual does not give that information.
I did not use 2x4s, but built a floor out of doubled 3/4 plywood to take the
Well, the old oven is being taken away on Monday and an installer is
delivering the new one on Thursday. The installer will take care of the
electrical (they'd even adjust the cutout if the new one needed to be
bigger). So we just need to provide a place for them to slide it in.
Why are you going to so much trouble to use the 30" oven? The 27"
Thermadors are big; big enough to fit the biggest Turkey you can buy
probably. If you were buying some smallish oven like a Bosch I might
see needing 30", but I certainly wouldn't rebuild cabinets for it.
The reason we are changing from 27" to 30" is because here in Canada most
manufacturers only supply their very basic model in 27" sizes, and the ones
with their features are only provided in 30" sizes. We are also were told by
the manufacturer's representatives that they are standardizing on 30" size
for the bulk of the models for North America, and are planning on limiting
the 27" models for economy and limited space situations such as apartments,
the same as they have done for stand-alone stovetop/oven units.
Rebuilding the cabinet is no big deal, I also had to revise the fridge
location to accommodate a 48" built-in from a 36" stand-in.
Hmm. I don't know what "limiting them to apartments" means. What are
there 20 million apts in North America? When you say "you were told by
the manufacturer, what does that actually mean? They're only shooting
themselves in the foot by making ovens bigger than the spaces that
people have available. If Thermador only makes 30" ovens and I have a
27" cutout then I buy a DCS. Frankly I'd rather have a DCS or Dacor
anyway. But since you get 10-15 years from an oven I don't see why
anyone would care what they plan to do in the future. Its not like
you're going to trade it in in 2 years. The only argument I'd make is
that a 30" is the same price as a 27", which makes it a better deal.
But not if I have to redesign part of my kitchen in the process. Then
its way, way more expensive.
OK, so they took away the old oven this morning, and I'm a bit
surprised at what I see. Under the old double oven, which from the way
the two enormous men were struggling weighed about 200lbs, was
supported by 2 3/4 x 3/4 runners with 3 1.5" screws each, and a 3/4
particle board shelf over them. No special supports in the rear. I'm
wondering how these could have worked? Is the weight distributed so
evenly that such small supports could work? I'm thinking of using the
same shelf (since it fits perfectly of course) rather than the 2 x 4
runners. If there is no framing behind the cabinet ( I think there is
framing in the front but not the rear, how much weight can a shelf
thats just screwed into a 3/4" cabinet be expected to hold?
