Optimus No7 stove?

Not at all a 'no no'. I installed a smaller jet in a Coleman Handy Gas Plant in order to use kerosene rather than the gasoline the stove was intended for and wrote in a previous post,

 

You gas plant and furnace guys are pyromaniacs....!

 

@Ed Winskill

I hope you're not implying there's something wrong with that... .

Well I'm finally going to do something constructive with the No7.I'm making a pot of tea for my wife and I out on the porch.

Please clear up some confusion concerning the OPTIMUS #7 campstove... I've heard people state that it is a KEROSENE ONLY stove but the one I have has ever only been used with white gas/ coleman fuel. I have run it several times with coleman fuel and it works like a champ ! Zero issues! Please can someone show me nomenclature directly from Optimus stating that this stove is kero only?

 

Using anything other than paraffin/kerosene in this type of stove is a danger to the operator and others around them for two reasons:

1. The non-return valve is of a design of adequate safety when used with less volatile fuels, but leaks can and do happen which could be disastrous with Coleman fuel.

2. The air release screw is a feature not found on stoves used with Coleman fuel- if used it will vent flammable vapour, unlike when the correct paraffin/kerosene fuel is used.


If you subscribe, there are many Optimus catalogues available to view which list stoves of this design as for paraffin/kerosene. This was an era when a stove listed as 'for kerosene' would not usually come with big warnings about the danger of using other fuels, it was assumed the user could read and would follow simple statements!

 

While CF may run in a kero stove,. you are asking to get put in a burn ward. Don't do it!!!!!

 

2 ways this stove running on gasoline will make sure you can never grow a beard again or worse. Get 2 small metal trays and put a couple of teaspoons of kerosene in one. Try and light it with a match. This is the fuel your stove is meant to run on. Now do exactly the same thing with the same amount of coleman fuel. Best do this outside well away from anything.
Now search the forum for leaking non return valves. You will see they happen a lot. In this style of stove the end of the pump tube is in fuel so when the valve leaks fuel is pushed up the pump tube and all over your bench. Which fuel do you want all over your bench a few inches from a big hot flame?
Next have a think about how you control this stove. It is by letting gas out of the tank of pumping it back in. With kerosene it is mostly air but with more volatile coleman fuel its got a fair portion of fuel. Think of that tray of coleman fuel and the match except think what happens if the fuel was warmed first. Dont actually try this.

 

You can drop a match into a can of kerosene and it will extinguish. If you do the same with CF, it will light on fire quite violently. CF stoves are sealed far better and have many more safety features than kerosene stoves.

 

Generally, but not always. The 111B is one example. kerosene technology with the capability to use CF.
One should always use caution.
