We have acquired a Rangemaster 110 dual fuel cooker, 18 years old, gas
hob, electric ovens (2), grill, griddle and warmer. To fit will require
demolition of existing built in hob and ovens, so I would quite like to
know that the Rangemaster works before proceeding too far. At least I
would know what bits don't work, if any, and order replacements.
Would it be reasonable to just connect it to a standard 13 amp socket,
and test the various parts one at a time? The recommended connection is
30A, with the maximum draw 3kw per item, which is about 13A. I envisage
trying the ovens one at a time, just on a low setting, to see if the fan
works and the element starts heating. The worst outlook is blowing a
Yep - that'll be fine. You should be able to test each device flat out -
remember a 13A fuse will withstand a moderate overload for quite some
time (20A for at least 30 minutes sort of time). Obviously it's not
recommended to stress your sockets like that for too long so feel the
Thanks chaps. The cooker cable is, of course, far too large for a 13A
plug, so I fitted a plug to the stoutest length of flex I could find,
then joined the two with a 30A junction box.
Result! Everything works. Ovens, grill, fan, warmer, even the gas
igniters and oven lights. The cooker itself has spent the last two or
three years in an open fronted granite bothy, but only needs a good
clean. Rangemaster themselves were very helpful. They told me the
build year, and sent an original manual (pdf) by email. Very pleased.
Recommend doing a gas pressure drop test with the cooker connected onces
it's convenient - this will not be anything that can't be fixed but
you'll verify that all the valves are able to shut off tight.
Ah. Yes. That is the slightly more complicated Part II. No mains gas
here, so will have to be LPG for the four burners. Luckily, I happen to
have two large cylinders in the garden, which will probably suffice. One
is full, and both are marked 47kg Calor Gas propane. The cooker came
with two sets of jets, so hopefully one set will suit propane.
It will be a little man in job though, as there is no pipe for the gas
yet, and hopefully whoever installs will have enough clue to run the
appropriate pressure tests etc. I gather that the installer has to be
'gas safe' anyway, not that it matters, as I certainly wouldn't do it.
Having said that, do the cylinders have to be outside, for safety? The
connecting pipe would have to be copper, with rubber for the final
couple of feet?
Well, a paid installer has to be registered with GasSafe - and check his
card to make sure it carries LPG as a competancy.
Ask him if he would do a appliance connected drop test as it's a second
99% unlikely to find any problems, but you'll know for sure which is nice :)
Something like that - neighbours still have a couple of big red bottles
for cooking (we went mains gas a decade back but I guess it's not worth
the bother for just a cooker).
Yes, there is a useful list of fitters at the Gas Safe site, but we
appear to have hit a problem. I phoned a couple last week, and one
phoned back today. He stopped me as soon as I said second hand cooker.
He will not install, or even just run a new pipe for a second hand
cooker, because he cannot be sure of the condition of the cooker. Seems
a little extreme to me, but I'll try some others, and see what they say.
I would have thought the whole point of testing was to check the
condition of the cooker, but what do I know?
Success, I think. Another chap turned up yesterday, and seems perfectly
happy to run a gas pipe from the LPG cylinders outside, check the cooker
jets, connect gas and test. He said he is not a cooker repairer, so he
will install the pipe, connect and check but, if there is a pressure
drop when the cooker is connected then either there is a leak within the
cooker or a faulty control valve at which point he bows out, which I
suppose is fair enough.
Yes, I used my big wall oven that way when I was building the house,
just plugged it into a normal outlet. In fact its still like that 40 years
later, I haven't bothered to install it properly. I just have to ensure
that I don't have both the oven and the grill on at the same time.
There is no point in a low setting in your case, ovens either have
the element turned on or off, the low setting just means that it
isn't on as long.
