Gas cooker bayonet fitting - how hard is it to get the right angle?
Jón Fairbairn
doing this myself, I'm not. So it's OT, but I'm sure someone
here will know:
While we had some friends staying in our flat, the gas
cooker was condemned, so we had to have it replaced at a
time when we were away, fitted by someone from the vendor.
When we got back to it, aside from the usual pieces of
brassware discarded under cabinets and so on, what stood out
was that the cooker stuck out further than it should. The
back of the cooker has two "feet" to space it off the wall
(one of them has been bent upwards, which hardly inspires
confidence) and there is a fair distance between these and
the wall. Closer inspection reveals that this is because the
hose connector isn't vertical.
If you picture the gas pipe running horizontally parallel to
the wall, the bayonet connector forms a right angle, one arm
of which should be vertical, but instead is angled out from
the wall, making the hose arrangement take up more space
than it should. So far as I could see by peering down the
back of the cooker, there is a threaded part soldered onto
the supply pipe and the bayonet fitting screws into this.
So, finally, to my question: is it difficult to fit these
things so that the hose comes out vertical? How big a job is
it for someone to put it right?
Apologies for the verbosity, but I'm not too awake right
now.

If I'm visualising this correctly it depends whether the pipe up to the
bayonet can be sprung away as it'll probably be necessary to unscrew the
bayonet connector, clean/check the threads and apply fresh PTFE tape,
thread-sealing cord or jointing compound, then screw it back in leaving
it set at a suitable angle. Just twisting it in situ could result in the
joint leaking.

Yes, I expected that part. What I don't quite follow is how
one can reliably get a good seal with the bayonet in a
particular orientation -- I guess you don't have to screw it
in all the way, but fill any space with thread-sealer or
what have you?
But anyway, I get the impression that it's a fairly short
job, so someone qualified should be able to do it without
charging the earth.
Thanks.

If using (suitable) jointing paste it's gooey enough to seal provided the
joint's done up fairly snug, and tends to harden over time setting the
joint tighter. PTFE tape (gas approved, thicker, unsintered) requires you
to screw as far as it'll go leaving it at the right orientation, which'll
generally be pretty tight (since the threads are tapered). Locktite
thread sealing cord likewise but if you get the right amount of thread on
you can get it pretty damn tight, and if you find you've turned too far
you can back it off to the desired orientation.

Interesting. Thanks.
