Gas oven - flexible gas pipe NOT allowed!

Just had a Corgi round to install a built-in Baumatic gas oven with hob
above. However, he and I were both scratching our heads over the oven
installation instructions, which state:

"Warning: the use of a flexible rubber tubing attached to the outlet
connector is prohibited because it cannot be inspected".

Now given that the gas hob definitely needs to be fitted with fixed pipe
work, how the hell can the oven also be fitted that way? There's no way
to access the back of the oven. We wondered about the wisdom of making
a large access hole in the external wall of the house but that seemed a
*tad* like overkill, so the Corgi just fitted the oven in the normal way
using a rubber hose/bayonet connector.

Bizzarre or what? Anyone able to shed any light on this?

My understanding is that a fixed hob cannot be plumbed in with a rubber pipe
and must have a copper fixed pipe.
Rubber pipes are still allowed on cookers/ranges with wheels ... but a
safety chain should be fitted to avoid stressing pipe of the moving unit.

Yes, the hose he used is not "a flexible rubber tubing" (which
is indeed not permitted). It is a flexible metal hose with a
rubber covering. I would have expected a CORGI to know that.

Flexible rubber tubing is what you had on a bunsen burner at
school.

I've only fitted one gas oven and I used a flexible connection that was a
few years back. However I do note that the safety guidelines as found in
some recent (2005) gas fitting texts state that rigid pipework is to be
used.

The only way I can think this might be achievable is to make the
service isolator accessible in an adjacent cupboard (say). Then make a
compression joint behind the oven accessible from an adjacent cupboard.
Thus the pipe can be disconnected and the oven removed.

I really need more info why the flexible hose is not permitted here.

Speaking of gas pipes, is it stil possible to get brass "gas barrel"?
I want to make some replica gas lights (wired for leccy!), and would
like to use screwed barrel and fittings.

That would make sense, but you'd maybe expect the instructions to make
the distinction between pipe types a bit clearer? Though I have to say
that in other respects they are as clear as mud; it took me several
reads-through to understand the ventilation requirements!

(Well, probably not 'rubber' any more but still 'flexible' something
and no steel etc)

All the best ..

Baumatic instruction books/leaflets are truly diabolically awful, I
have a couple. Both the installation instructions and the user
instructions are equally flawed. The examples I can remember from our
dishwasher instructions are:-

Dishwasher installation - it tells you to adjust the door closure
and tells you how the catch can be moved back and forth. However
it doesn't tell you how to judge when it's correctly adjusted.

Dishwasher use - it has a list of the dishwasher programs (there
are eight) which have descriptions like 'heavy', 'very hot',
'severe' etc. but absolutely no indication of whether 'severe' is
stronger or less strong than 'heavy' for example. The programs
are not in 'strength' order either, they appear to be entirely
random so it's completely impossible to decide their relative
washing power. The only way to guess, approximately, is by their
duration.

Fixed ovens and hobs MUST be installed with fixed pipework. As the
instructions state it's impossible to move a fixed oven to inspect the
hose.

Moveable cookers can be installed with flexi-hoses.

To fit the oven it is possible to have access via the kickspace void
beneath. Fit a pipe on the oven and access this via the kickspace void. A
compression joint can be used here for a disconnection device.

IIRC solid piping was required for some commercial catering equipment to
prevent things being moved out from under flue hoods where applicable. I
wonder if this is based on the same logic.

But if the hose comes into contact with the hot rear metalwork of the oven
it can exceed the rated temperature of the Gas hose. I am Corgi registered
and fit the appliance's strictly as per the installation instructions, as
required by the GAUR.

Doubt it as it's a built in oven which doesn't require any extraction
and the required kitchen extraction isn't required by CORGI so it has
nothing to do with gas ovens. Even if there was extraction in the
kitchen it isn't neccesarily over the oven.

I'd have thought that screwing it to the floor would have been a better
solution.

FACT The regulations state the hose should not come into contact with hot
surfaces or exceed its temperature limit, that is fact. "The rear of the
oven shouldn't get that hot though" that IS a guess isn't it ? Have you got
access to the manufactures test data, are you prepared to leave it on full
heat for hours in the summer, then measure it, if not you must follow their
installation instructions, which do not permit the use of a flexible gas
hose, period.

I'm thinking along the lines of a wood/chipboard top to the unit possibly
with a gap at rear. Moving the oven forward "might" result in the heat from
the oven vent being under the top, unless the vent is hidden in a grille at
the front.
As many kitchen units are fully enclosed at the rear presumably any
manufacturer will have been asked this point before and maybe a question to
them might be better than asking us to guess from here.

So are you saying the insulation on a built in oven is poorer than on a
freestanding cooker where a flexible connection is allowed?

I am saying the connection must be made in accordance with the instructions
supplied, this is why no new gas appliance (or second hand) can be installed
by law without installation instructions being available to the installer,
simple as that. New free standing appliances normally have measurements for
position for the bayonet on the wall, so that the hose hangs in a specific
place on the rear away from the hottest parts of the appliance and so as not
to touch the floor when the appliance is in place. This wouldn't be
possible with an oven because you cannot see it with the oven in place.

Immediately to mind I have seen water boilers and freestanding grills
positioned on top of stainless steel catering kitchen furniture (table type

slide them around and end up not under the hood. Just because you haven't

Then it is attached to something then isn't it. Just because it isn't
on the floor doesn't mean it can't be fixed down.

Also, I can't believe that anyone would connect a rigid supply pipe to
a non-fixed piece of equipment.

This thread is getting dafter by the minute.

Quite so! You are arguing about something you obviously have no real concept
of.. Catering equipment is not domestic, and you obviously don't work in the
game so I suggest you drop it.

Re the OPs question the best solution is going to be ask the manufacturer of
the oven.
