Calor hob

I am ready to go down the route of replacing our electric hob with a gas one but it would have to be Calor.

Many of the hobs on offer state that they are OK with Calor so I guess there isn't a problem but if anyone with more experience in these matters wants to point out possible pitfalls.....

AFAICR every gas hob I've ever bought has come with a little bag containing replacement jets to swap in if you're using the bottled stuff. Never have though!

In my experience (having installed three or four Calor hobs in various houses) you need to make sure that the hob is supplied with a set of Calor jets, in addition to the 'town gas' ones.

You'll need to unscrew the town gas jets and fit the calor jets (the jets with the largest holes are for the largest burners, and so on).

Having done this - there's an adjustment on each burner (often accessible by removing the control knobs) that has to be screwed down or even shut to allow a proper range of adjustment on the control knob.

No real pitfalls - just make sure you get the right jets _and_ the correct installation instructions. The house we're currently in had a new calor hob fitted - but the ratbags at Zanussi technical services wouldn't tell me where the adjustment was because I 'wasn't competent'.

Some kind soul on this newsgroup pointed me at the right instructions

- and the adjustment took only seconds !

The other thing that may be worthwhile is to fit an automatic changeover valve and two cylinders. This means that you get an nearly-instant changeover when one cylinder empties - but the downside is that you may not notice you've emptied the cylinder until the second one runs dry..... In any case - we've always found that the

47kg cylinders we used for gas hob and oven lasted ages - typically 18months - so using just the one cylinder may not be a big problem for you.

Good luck Adrian

Nice one, thanks a lot.

Sods Law states the single cylinder will run out half way through cooking a special Sunday lunch... Have the auto change over valve and just check to see if it has swapped over once a week when checking your oil level.

It's down a hole drilled in the shaft of the control knobs, as you doubtless know. There's a tiny screw at the bottom that has to be tightened up.

The only problem I had with my new Zanussi hob was making this adjustment, since I didn't have a screwdriver both long and narrow enough to fit down the hole. I ended up making one from a piece of wire coathanger.

Ah well

In the last-but-one hob it was a screw down the centre of the knob - but in this current house they'd hidden the screws just to one side of the control shaft. Sneaky !

Had just the same problem in last-but-one house. Ended up grinding a flat 'blade' onto the end of a thin allen key (brutal but effective !)

Doesn't require any torque - the screws just need to be gently seated...

By law whoever installs it must be 'competent' to do so (as for natural gas). As LPG is denser than air and escaped gas can find its way down drains or underfloor voids and build up into explosive mixtures there's a fairly real danger involved, apart from the normal lack-of-ventilation => Carbon Monoxide hazards to look out for,

We've found that retailers recoil in horror when questioned about bottled gas so we would be interested in your final decision.

There are two different gases used as bottled or LPG ( Liquid Petrolium Gas). Both are in the same chemical family as methane. Butane (C4H10) in blue bottles or propane (C3H8) in orange. Either can be used with the appropriate regulator but butane can't be used from bottles stored outside as it does not flow at low temperatures (freezing?). Butane has a push in regulator released with a button or knob on the side. I break all recommendations and turn the bottle upside-down and tap the end to tip out bits of dirt before connecting it, otherwise it leaks. Propane regulators are different (left handed screw fitting??)

I think most people use propane - I've had sufficient experience of pouring hot water on butane cylinders in winter to know that there's really no point in using it when propane works just fine, and indeed is probably easier to find. Yes, the cylinders are LH threaded. There's a sort of bullet-shaped thing on the end of the pipe which forms the seal. The bottle has a tap on it - you don't connect directly to the top of the cylinder. They come with plastic plugs in from our retailer, so don't get a chance to get muck in them - and the connector is somewhat bigger than your typical camping gaz cylinder.

And yes, get a auto-changeover regulator.

cheers, clive

The message from Adrian contains these words:

You could try the halfway approach by having 2 bottles on a suitably valved manifold. It won't stop the problem of the gas running out halfway through the Sunday roast but if you buy a new cylinder when one runs out the discomfort will be shortlived.

The message from "Phil B" contains these words:

When the world was young (or I was anyway) all Calor (grey butane) bottles had threaded connectors rather than those nasty push-fits. Some of the small bottles still do and they have a left hand thread. The rise in popularity of Propane might have driven the change to push-fit on Butane bottles in which case my camping burner may become unusable without more modification than it is worth. 50 years old and not in the best of health. {That's the burner, not me.:-)}.
