30mb cooker and propane

[Mistroma]

I am pretty sure you will find that if is designed for 30mb it is suitable for butane or propane at 30mb.

If it had been designed just for butane it would have been 29mb. If it were for propane only it would have been 37 mb

This adapter may be of interest to the OP as it will allow a propane bottle to be connected in place of a butane one with no further modification or even hose change. Useful if the existing installation has a bottle mounted regulator.

.

Thanks for the link thats just what I need to run both.

I was looking at these as well and had found that CAK Tanks seemed to sell a good range and prices looked very good. I downloaded their Cat. & Prices recently so did a quick check.

http://www.socal.co.uk £19
http://www.caktanks.co.uk £13.49

Looks like the same piece of kit and you can find it on page 58 of their catalogue (Downloaded version). They might be updating their web-site as on-line cat. says page 55 and then can't find that page).

Just download their latest cat. and price list files and order by phone. I've never used them before but intend to put in an order soon for a water tank and some gas adapters.

check the link below you can get the bulkhead reg, pigtail to butane cylinder and the adaptor to the propane cylinder so you can use either type of gas. and via this setup either cylinder will provide 30mbar

sorry haven't sorted how to copy the pics.

PS. I should have said do not use a normal 37mbar propane reg if your cooker is badged for 30mbar.

I intend to keep my 30mb marine regulator and I ordered the propane adapter yesterday. (the red handle unit to the right of your picture)

May be not after all

Apparently the Gaslow adapter may not fit on the small 3.9kg propane bottles.

Ok for the larger ones but may not fit on the little ones. Not enough room for the red "handwheel"

Like wise the "easy-fit" propane bottle hoses.

UPDATE:

The adapter has arrived and the red handwheel has just enough room to thoroughly tighten up on the 3.9kg bottle

Thank goodness!

Thanks for the feed back.

Cant have you losing hairs over it now can I

...avoid the problems associated with butane at low temps ie like now!

I use propane at home. It used to freeze every winter, until I made a "gas cozy" out of a BBQ cover and some foam.

 

[saltylegs]

Putting a cover on the cylinder will actually cause lower offtake as the cylinder does not get heated by the "warm" air. boiling point of propane is about - 42 c and the cylinders will perform very well in the open air to around - 25 c provided the offtake from the cylinder is not too high.
If the cylinder cannot cope with the offtake fit a bigger cylinder or manifold cylinders together.

Freezing point of propane is about -190C . Your home must be very cold

Fpt of n-butane is -138C

I think you must be getting confused with the fact that the boiling point of n-butane is -1C so wont vaporise effectively below 3 or 4 C

Bpt of propane is -42C so is usable down to any temperature most of us will encounter.

Simple it works-I run everything on propane -goes back to a New Year two decades past spent freezing with our kids in the caravan in Aviemore because the butane would not vapourise.
Issues only arise when switching from lpg gas to domestic methane.You then have to fit a full set of different size jets.
Personally would not bother switching back and forth-a bottle mounted regulator costs no more than about £5.Remember Propane bottles are threaded anticlockwise;butane clockwise.
The handwheel regulator-I fitted one but sometimes worry as it has rubber seal wheras the spanner on one has just a machined taper?

Better check your calor butane bottles all left hand

You sure? I thought propane and the small Calor butane cylinders were both left handed.
A propane cylinder has a female thread whereas the small butane one has a male thread.

Camping gas bottles have a right handed thread

 

[ffiill]

Yes-when I wrote this something flashed in my head-now you mention it but I am sure that it used to be that one was clockwise and the other anticlockwise to avoid confusion-or am I wrong-used a butane bottle last week for first time in 20 years.Or is it that propane useds a taper and butane a flat washer?
I use propane all the time for domestic cooking and heating as well as on boat.

Butane flat washer (BTW use the new washer provided in the plasic cap when you fit a new butane bottle)

Propane are a bullnosed connector ... no sealing washer

yip that's more like it, must be getting late.

Bullnosed normally refered to as a "POL" which is the brass cone but the wheel type with rubber face is getting more popular in recent years as no tools required, (no tools does not refer to a gas safe installer)

 

[VicS]

Any idea what "POL" means?

Edit: Found it : " Prest-O-Lite "

But the definition is


POL Prest-o-Lite fitting. A fitting used exclusively for flammable gases. Easily identified by the notches in the hex of the fitting. All POL fittings are tightened by turning counter-clockwise.


So does not refer specifically to the bullnosed part... The same bullnosed connector is used on non-flammable industrial gas cylinders IIRC. eg oxygen, nitrogen etc but with a RH thread

the notch in the hex refers to weather it is suitable for cylinder or bulk tank, one has 1 notch the other 2 but can't remember which is which.
there is a slight variation in threads and strangely one will go into the other but not the other way around if you know what I mean.

If the cylinder cannot cope with the offtake fit a bigger cylinder or manifold cylinders together.

These are already the largest cylinders, it's the regulator that freezes.

 

[saltylegs]

If the regulator has frozen its because water has gotten in through the vent and freezes( due to the low temperature of the vapour) on the atmospheric side of the rubber diaphram and thus stops it moving against the spring so the flow of gas stops, you can also have the opposite effect and the diaphram can freeze in the open position and give you almost tank pressure through to your appliance, not good.
If your reg is freezing deep six it.
