Firebird Heatpac 90

Wearb

Anyone got the FB settings for this old baby. It isnt the same as the one in any of the manuals that I have. This one has a G5 burner. (All manuals have RDBs) It had a .5 60S nozzle and I managed to get it well setup with a same size replacement. The combustion chamber was longer than wide, so I stuck with the 60. From any manuals that I have, all the lower range FB nozzles are 80. As I said, I am happy with setup, but just curious.

Go with a .60 80degree H @11.5 co2 pump pressure 8.0
Or look up firebird hideaway or super q room sealed they both have same burner

Thanks Robbie. Do those boilers that you mentioned have the same baffles as is in the photo? The chamber looks a little narrow for an 80.

jimf

that's more or less a popular 90 would agree with Robbie re nozzle and set up but if your happy with your set up leave well enough alone eff somewhere around 82% gross and your on the pigs back

Wearb

Got 83.9%
I will try an 80 next time to see if it makes any difference, though it's going to be hard to improve on it. Maybe I'll get another one to play with before end of season.

jimf

will b hard to improve on that wearb that's the old design baffle set up just out of interest what kind of fg temp did you get

baffles look good in that boiler some of them can reach into the 280/290 without any obvious reason

Just under 200. Those are after being cleaned, though in great condition. It must be a tolerant boiler. Hadn't been serviced for 5 years.
Pump was at 5 bar. And air was at 2. Set off my co alarm on analyser. Still not a bit of damage. Go figure.

It was at 1.5 and 8 bar when I finished.

jimf

its funny you say 5 bar pump pressure I have come across a couple before reading the same

if I do I advise customer of the need to increase it first incase the pump has failed at that pressure because the first thing you will be told is twas working fine this morning

Didn't scudo2 design and make his own baffles that were much better and efficent than firebirds design?
