Hi all, relatively new to the gas industry about a year and normally just do fires and boilers.
The only reason i have the cookers ticket is for lgsc's. I am fitting my first freestanding cooker tomorrow and i have a few questions which may sound dumb.
1. Is changing all the injectors (converting NG to LPG)much the same as a gas fire/old boiler injector take them all out and just do them back up tight with no ptfe or compound on?
2. This particular cooker has some strange 1/2" male on it rather than the traditional female thread. Can i just use one of these (https://www.bes.co.uk/1-2in-equal-socket-female-x-female-malleable-iron-galvanised-8089) with ptfe both sides, just seems a bit rubbish?
3. When testing working pressure on NG i normally have the three or four largest rings burning with the manometer hose held onto the smallest injector with the gas tap pushed in which should give me my working pressure. I assume i'm doing this bit right as that's all i ever saw during my apprenticeship.
But when doing the same with the last two LPG cookers i've lgsc the pressure dosn't rise correctly and when i remove the manometer hose a flame flys out of the small injector when removing the hose as if its ignited in the metal connecting pipe and back fed through that injector taking my arm hair off.... Have i just been really unlucky or am i doing something completely wrong here and being a muppet?
4. How much are GSRI like you fellow gentleman are actually giving a massive concern about gas pressures on cookers. As it seems every one i ever go to is under-gased like as if its general conception to just bang it in regardless as long as the flame pictures correct its good enough...??
Thanks in advance
