Raypak Hi Delta 2342C in practice
The 2342C is the 2,340 MBTUH size of Raypak's Hi Delta non-condensing copper finned-tube hydronic line with cast-iron headers. The official ratings tables print 2,340 MBTUH input and 1,966 MBTUH Type H output at 84% thermal efficiency, with 4-stage (H9) firing, a 113-7/8 in casing width, a 2" NPT gas connection, a 16 in flue collar, <12 A boiler amp draw and 1520 lb approximate shipping weight.
Hi Delta models are documented by I&O manuals 241663 (302C-902C) and 241664 (992C-2342C), with submittals 241877 and 241879 carrying the rating and flow tables. The line is available for indoor or outdoor installation and vents as Category I or III equipment; natural gas and propane are both listed.
