Gas Pressure?

Anees · April 15, 2006

No nothing to do with Supercharger/Turbo charger boost pressure! :P

Hi guys,

I've been preoccupied for the last few week with decoration and rennovation of our new house extension. Just had our new range cooker fitted yesterday and the amount of flames that come out of the burners is abit dissapointing. It has 6 burners + a large wok burner that just seems to be underpowered.

I was looking in the instruction book (last resort :P) and it says the cooker needs "G20 Natural Gas @ 20mbar" of pressure.

It looks to me like the pressure is too low.

Is this adjusted from the cooker normally or from our gas supply? Is it something I could change or should I get the fitter back again?

Thanks,

Anees

Is the cooker available in both Natural and LPG versions? If so, it would be worth checking that you've got the right one. At a place I used to rent the boiler ran on LPG but had a bigger Natural Gas injector fitted by mistake, was like a blast furnace until the injector was replaced. If running an LPG cooker on Natural Gas I'd assume the reverse would be true, i.e. pathetic cooking flame.

The gas pressure can be measured at the injector of one of the LH Hotplate burners.

(Depending On Manufacturer).

Remove the pan support, burner head and caps. The injector is now accessible.

The pressure should be 20 mbar with a minimum of 3 burners operating.

You could have low working pressure at the Gas Meter. Faulty Govenor

This should also be checked it should be 21mbar +/- 1 mbar. With the 3 burners operating.

There are several other things that can effect the burners:-

Size of the room, openable window/door - it may need ventilation.

If the volume of the room is less than 5m cube an air vent of effective area 100cm squared is required.

If the volume of the room is between 5 - 10m cube an air vent of effective area 50cm squared is required.

If the volume exceeds 11m cube, no air vent is required.

You will have to check your manufacturers instructions for ventilation requirements for your appliance.

Check that they are the correct injectors for G20 gas.

Check that the correct injectors are fitted to the correct burner.

all the best

Great thanks to the two Pauls for the detailed answer. It turned out that when the gas fitter turned the gas back on after installing the cooker he hadn't fully turn the gas lever to the ON position. So it was low! Simple fix in the end!

Thanks for the great advice, much apprecaited. :D
