Verdict in brief
The Delta Limited H9-2339B adds 270 MBTUH of input and 227 MBTUH of output over the Delta Limited H9-2069B on the same Delta Limited platform. The 2339B is the largest Delta Limited at 2,340 MBTUH input and 1,966 MBTUH output, with a 16 in flue against the 2069B's 14 in.
Published manufacturer figures. Input and output are kept separate; blanks mean the manufacturer did not publish that value.
| Specification | Raypak Delta Limited H9-2069B | Raypak Delta Limited H9-2339B |
|---|---|---|
| Input | 2,070 MBH | 2,340 MBH |
| Output | 1,739 MBH | 1,966 MBH |
| AHRI thermal efficiency | 84 % | 84 % |
| Firing stages | 4 firing stages | 4 firing stages |
| Water connection | 2-1/2" NPT | 2-1/2" NPT |
| Flue outlet | 14 in | 16 in |
| Weight | 1,450 lb | 1,520 lb |
The H9-2069B is rated 2,070 MBTUH input and 1,739 MBTUH output with 4:1 turndown; the H9-2339B is rated 2,340 MBTUH input and 1,966 MBTUH output with 4:1 turndown. Both models carry the same published efficiency figure, so capacity is the variable rather than efficiency.
The 2339B is the largest Delta Limited at 2,340 MBTUH input and 1,966 MBTUH output, with a 16 in flue against the 2069B's 14 in. Both share the same 132 gpm maximum water flow, so the step up does not enlarge the pump or piping envelope. Shipping or operating weight moves from 1,450 lb to 1,520 lb, which matters for rigging and floor loading.
Both sizes are documented in the same official Raypak submittal for the Delta Limited family, so the decision is a heat-loss and plant-layout question rather than a documentation difference: size to the calculated design-day load, then check flow, connection and venting dimensions against the submittal for the exact model.
The Raypak Delta Limited H9-2069B is an indoor non-condensing copper-fin commercial hydronic boiler rated 2,070 MBTUH input and 1,739 MBTUH Type H output at 84% thermal efficiency, with 4-stage firing and a 14 in flue.

The H9-2339B at 2,340 MBTUH input and 1,966 MBTUH Type H output per submittal 242016.
Yes — the 242016 submittal prints natural-gas and propane ratings for both; only the 1999B is marked natural gas only.
A consultation includes a heat-loss review so the size is right the first time.
