Raypak Delta Limited H9-2069B in practice
The H9-2069B is the 2,070 MBTUH size of the Delta Limited, Raypak's indoor non-condensing copper-fin boiler based on the same basic design as the Hi Delta with a reduced feature set at reduced cost. The official submittals print 2,070 MBTUH input and 1,739 MBTUH Type H output at 84% thermal efficiency, with 4-stage firing, a 102-1/2 in casing width, 2-1/2" NPT water connections, a 2" NPT gas connection, a 14 in flue, 1450 lb approximate shipping weight and <12 A boiler amp draw.
The model-number key in the I&O manual (241330) reads H for hydronic and the following digit for firing mode — 4 for on-off, 3 for 2-stage, 8 for 3-stage and 9 for 4-stage — which is how the page's H4/H3/H8/H9 prefixes match the printed stage counts. Submittals 242015 (399B-899B) and 242016 (989B-2339B) carry the rating tables above.
Best suited to
- Commercial hydronic loads near 2,070 MBTUH input
- Budget-sensitive plants wanting the Hi Delta design with a reduced feature set
- Indoor installations on Category I or III venting
