hi guys,

I went to to a job today and the client had yunca leedz gas fire, the regulator was making a strange hissing burst  sound, like "shhh, shhh, shhh" and the jets on the fire are clear,

the flame in the fire was moving small to big in sync with the noise, it is a old auto changeover regulator outside on the bottles, there is no bottom end on the reg outside, just a pipe heading down below the floor over to the fire,


do I need to change the changeover reg?


cheers.

it was reading 2.08 with the fire running, i wound it up to just over 2.75kpa , it has a black hexaganal cap and a black flat plastic thingiee inside with a allen key shaped hole in the centre that you would wind the pressure up with,

I dont want to replace the reg if i dont need to, the fire goes well otherwise

fluid in a low spot on the pipe work, sounds like you'll have to drain out some condensate.

if you change the reg and it is still there then you'll wish you'd checked the line

check that first because it will only cost you time

The pressure is pushing against the fluid then pushing past it, the shhh shhh is the fluid going back and forth

the noise comes from the reg because that's where the back pressure has its effect, good luck let me know how you go.
