Thanks Billy. I have that.
I am looking for correct nozzle size and angle, and combustion settings. Looks like I can replace like for like nozzle, but I always like to be able to check if the correct nozzle was fitted last time.

Short combustion chamber so maybe stick with an 80deg nozzle
Download a nozzle size calculator (app on iTunes) or use your nozzle sizing charts (in Oftec books)
and size from the boiler output. (use a 90% efficiency figure)

Boiler says max 100,400 btu, remeber the G3 is 90,000 btu max

Like a 0.6USgal 80deg H at 8 bar would be 23kw output

Been through the "Complete Technical Guide" but it looks like i was short changed again, not there.

I did have this boiler myself for years and although i don't recall the details i do remember that it was a .65/80s nozzle i used, it was pre FGA so it was by the eye but she ran clean for years. I think there was a predecessor to this sectional boiler made by Clyde and was fitted with a Clyde Climatic 30, the early Mectron, you could see if you can find the details of that.

Looks like your still smarting so. Pretty petty

Just being humorous DGOBS, surely we can still show humor and have a little banter between friends. :pac::pac::pac:

DGOBS

For sure.

Thanks. I spent about an hour looking online without any luck. I will see how it looks with current nozzle when I pull the burner and compare it to chart sizing.

I think we all spent too much time checking I know I have

but as dgobs says not a very deep chamber so 80dg I would think are prob best

I don't know whether im wrong or right but I always set pressure at 8bar and fga it from there that's because I don't have mi to hand if I get a good fga reading im happy
